I hate when guys tear the rotary out of an rx7. I just wish I could arguee with them. The rotary was a unique and amazing engine! And, in my opinion, as long as they are willing to acknowledge that fact, then do whatever you want with the car. It's just a car. That LSX is a badass engine and it will make that car nothing short of a monster!! I personally want to put a gm v6 in a first gen and use the rotary for a sand rail with a vw transaxel. Sweet video!
@pinkpanthercow And you've never had to deal with a rotary you son of a bitch. They're a pain in the ass. They cost a shit ton to maintain, and you can guarantee you'll be maintaining them often. They are a kick ass engine. I loved my to death. I wanted a car that could pass inspection and would deliver me a lot of HP for not a whole lot of money. I did my entire swap for under 2000. Best thing I ever did.
how did you do the harness? and is this a 5.3 from a truck with a 4L60E auto trans? i'm doing the same swap once someone can help me figure out the harness work that will be involved
@2URBO2 It is a very compact V8. I am going to be repairing and building up the V8 in my Corvette (because I blew it last week) and am swapping in an iron block version so I can drive it in the meantime. Once I get the new engine built I will have an extra V8 laying around, so I figured I would swap it for the V6 in my Audi. Oddly enough, the Chevy V8 is both lighter and smaller in every dimension than the DOHC V6 in my Audi. Well...except for displacement.
@2URBO2 actually it will fit. however i think the benefits are outweighed by several things, 1 cost lol. 2. weight?,and 3 the power of said engine could tear teh car in half. id love to do it tho if money werent an issue. but my home is paid for, and id have to mortgage my house to finance this project. ls1 is far cheaper. and benefits are similar
@yamahonkawazuki Well.... Cost would be somewhat higher, but THAT much more? Buy a wrecked viper or srt-10? Or maybe a triton v10 from a excursion? Well, the weight is the real issue, the v10 is a heck of a dump of aluminium and cast iron..... You'd had to have the engine in the middle of the car to prevent it from getting dangerously heavy in the front... Hehe, i think the rx-7 chassis can take it ;)
@2URBO2 Thats the thing, how many wrecked Vipers do you see? They are not cheap. We cant forget the 6 speed viper trans is BIG MONEY cuz its fricking SOLID GOLD. You can get an LQ9 6.0 (LS based GenIII) with harness for 350$ from the junkyard looking pretty, I'm sure you can get them even cheaper if you look.
they may take some oil but like every engine, also they do NOT have to be replaced after 60 miles. so if you do not know what you are talking about shut the FUCK Up!
@aji8 omg just fuck off you are a fuckin noob just go kill yourself and do everyone a favor all you do is come on youtube to pick fights i have seen alot of your posts all over rx7 vids
lol at rotards, moron and other dribble from this guy.
the mazda rx7,8 were designed for rotary engines, hence the rx (Rotary eXperimental) as similar to the mx 3, 5, 6 (Mazda eXperimental) models names.
why you bothered with a piston engine in this car shows who the real moron is. i laugh at these videos, seem pointless, buy a V8. i don't want to hear the repeatitive anti rotary crap reasons as so tired of reading them. same crap over and over like a robot.
what does that have to do with a v8 conversion? all iron rotory or all aluminum v8? twice the power. twice as reliable. no weight gain? i dont see the problem.
sweet ! yeah i think im gona do the same with my 87 turbo i have been screwing aroun with that rotary and yeah it sounds cool its light it dont have much moving parts but they just run to hot here in the the virgin islands and no body has parts its just been a pain in my ass so im going v8 prob a carb and a 75 shot of nos maybe a rebuilt 302 or if i can find a dohc svt mustang engine tranny i would go for that but i want to carb it so i dont know
Does any1 know if a 5.2L Piston can hit 700-930hp N/A on Race Gas? If so please send me the link to the video I want to see it. No Boost, No Nitro, Stock internals. Pure American Muscle power with no funny stuff.
Its a well known fact that Rotary Engines require a lot more maitanance and do not last as long as piston engines. Even RX8's Suffer from the same old shit
I am sorry but it is impossible to believe that a 3 rotor rx7 is running 5.38 sec in the 1/4 mile without using nitro. Top Fuel dragsters run anywhere from 5 to 4.4 sec in the 1/4 mile and they have anywhere between 7k to 8500 hp... the fastest 4 cyl top fuel makes 3k to 4k hp and needed the block to have all coolant and oil jacket moved to the outside of the block to produce that kind of power. now if you can show me that 3 rotor rx7 run those #'s without nitro i will eat my own shoe.
That was one of the stupidest comments I have heard. Nice way to prove your argument. Line up with what rotary? Any rotary? LOL. Most would lose, and then if it did win, it probably would break down a week later. They are junk engines.
where is your Rotary engine running in the 4 second range with Top Fuel cars, or even in the 6's for that matter.
Where are your regular 3 rotor Rx7s racing on an actual track beating over anything modified thats V8 powered... oh wait.. there isnt one, because the V8 is better.
900hp? maybe but not on stock internals or stock turbo. v8s have clearly gone over the 400hp range and do it without boost or reliability concerns. and the weight issue? i doubt it All LS engines are aluminum in cars and dont weigh that much. its clear you are the one whos full of shit
No, the point was that the BASE V8 engines in cars today do NOT make that kind of power. Only the higher end models. Unless it is the "base" engine on an ultra high end model of that car or truck.
and i suppose the sti has a base engine? no. the base rngine would be the wrx engine which only has like 240 or 260 something like that. the sti has 300 and that car goes for like 35 grand. even a 2002 camaro z28 or ss had over 300 and they only cost like 25 or 27 grand
well i agree with you but people love to bach american v8s. in reality there pretty damn good engines. as a matter of fact the most powerful streetable engine currently is an lsx that can support 2500hp and still be streetable. oh but dont put that in the valiant by the way keep it old school
I will tell you where the rotary engines are that run that fast. They are in the shop being rebuilt all the time as they are glass engines. While the V8s are out running, the rotaries are getting rebuilt. Obviously circuitracer150 doesn't know anything.
Poor guys on the street trying to drive their basically-stock rotary fast and not doing maintenance is what kills rotary motors. Engines always get rebuilt in racing... because, if they're "racing", they're running the motor at it's ragged edge of reliability - even V8's. Take a trip to an ALMS race and see what goes on in ALL the pits.
So much misinformation on here. Nobody has an eyewitness experience. Internet rumors FTL
LOL..here we go with the blame again on the owner. I guess the rotary is the perfect engine and will last 500K miles and put out 5000 h.p. You are correct about misinformation though. I suggest you heed your own words.
There is such a thing as implied. All is for defense of the rotary, it can do no wrong, it must be the owner. That is the most stupid shit I have seen.. Keep it up moron.
I hope you have a rotary and it blows, which it will do. Eventually.
Here's something for you. An american V8 longblock has 99 moving parts to wear out. And they all DO wear out eventually (remember, just like ALL engines).
A rotary has three. They wear out also, of course. All machines do. Don't even think about twin cam V8's..
Here is something for you. You are an idiot. Just because one engine has more parts does NOT mean it wears out sooner. The same can be applied to OHC / OHV. According to your skewed logic, the OHC should have a much shorter life. WRONG!
The rotary wears out prematurely compared to the piston engine due to its DESIGN. I would like to know where you retards get your information. Must be fantasy land. My car with 140K was on its second engine when I bought it.
A 13B N/A makes 130 HP/liter. Apply that to a Rustang 5.0.. 650 HP. How reliable do you think that would be?
I'm a mechanical engineer, and love all engines, but for someone to say that an engine the size of a basketball that can put out in excess of 700-800 HP with 1.3 liters of displacement, is a bad design, just befuddles me. People don't appreciate innovation.
I'm only replying to these off-topic comments because I'm bored. I hope you're the same; or I feel for you.
You are NOT a mechanical engineer. You don't know how many rotards I run into that are self proclaimed engineers. If anything you are a bullshit engineer.
Proof is in your post as you would not question the wear of the rotary. You know nothing except how to lie.
I actually am. Ever heard of a little company named Elan Motorsports based out of Braselton, GA? I got my Bachelor's from Georgia Tech and worked on the design team for the 2008 Panoz DP01 Champ Car. I've got all the CNC suspension parts and CAD parasolids to prove it. Do you just like to argue?
Oh really?! and how can you prove this? Moron. Anybody can say anything on here. What we need is proof. All I see is still words! If you knew 1/4 as much as you say you would not have questioned the venerable 5.0. You have no clue thus you must be lying. Next you pulled hp/L into the discussion and anyone knows that is a ricer statement.
The problem with that logic, is we DO appreciate the innovation of the wankel. We just don't want an innovative car, we want a fast car, that gets the same fuel economy.
@DemoFly That is the perfect response. Main thing that turned me off to the rotary is how much damage a broken apex seal can do to it. Can even blow a turbo... O.o
@Tj1056 chances are hes got a t56 behind that engine which has a pretty high 6 gear, my brothers ls2/t56 gto gets 20-22 mpg highway with a mild cam too
@subaruracer107 well if you think about it a somewhat big turbo pushing low boost not working to hard would really boost the mpg if tuned right... :p and i like the PFC standalone for the 13b... can have 4 different tunes :D
"Here's something for you. An american V8 longblock has 99 moving parts to wear out. A rotary has three." Hmm! Let's examine this a bit more in depth. In the V8 when one part wears down for what ever reason the burden is then spread through at least most of the remaining 99 parts. spreading the decrease in efficiency rather vastly diminishing it through every part. Now when 1 part on the rotary wears down then that inefficiency has ONLY two remaining parts left to share that inefficiency.
Have you ever heard of tolerance stacking? How much of it exists in the path from: the crankshaft in the main bearings to the crank pulley to the cam chain to the cam pulley to the camshaft in the cam bearings to the lifters in their own bores to the pushrods to the rocker arms on their own bosses to the rocker arm bearing tips to the valve stem? If ANYTHING is worn out, EVERYTHING else gets the burden of being out-of-spec. I don't like their sole dependency on linkages of mechanisms.
Here is something for you moron. For so few parts the rotary is a maintenance and reliabilty nightmare. It can't have any more than a few parts or it wouldn't make it past day 1. The rotary is junk. Thjat is why people replace the boat anchor.,
Rotary engines may be a 1.3 but they do consume fuel equivilant to a much bigger engines and they use up more oil as well, if your going to have a rotary engine, you have to prepare for the constant maintenance it needs, the WHOLE engine needs to be replaced after 60k miles, oil needs to be changed every few months, there is no denying it is a very very smooth engine but people do replace them with chevy v8's because that engine has been around for years and its become a lot more reliable now
We now have Alfazbacchus07, another rotary liar. they live in a dreamland. It is cool, they need to try and be happy about something since the rotary is not doing anything for them and they were stupid enough in the first place to get one and face all the fallbacks. Sorry rotards. Rotary is garbage.
Still waiting 2 see a LSX Honda with a RWD conversion, but i guess 2 many people R busy putting LSX motors N places like an RX-7 where they don't belong. What about a LSX Silvia or LSX Skyline!!! Hell Y not a LSX Ferrari that would be a huge upgrade from that slow ass V12. If u don't like rotaries then stay away from RX-7's please so those of us that do like them have a place to put them N CARS DESIGNED FOR THE ROTARY.
It's possibly the LSX-block, which is a very expensive motor. My buddy has one in his F1-procharged Z06 and he pulls 1k-hp out of it. the LSX is one of the few or the only small block that can be bored to 500-cubic inches.
i hope you guys have somthing to put all that power to the ground or all that's going to do is do dounuts in the middle of the road so hope you got that down and by the way great job
assuming you're comment refers to the weight difference of the rotary and ls7. to make this short, the ls7 weighs 450 pounds with ALL accesories. 20 pounds more than the rotary :)
lol thats cool...but in my very obese american world every lbs counts man! i even crap before i go out for a drive haha just incase i dont lose muscle control and shit my self while driving haha
and performane wise it wld increase it because listen closely.. u listening? i dont want to lose u with ur preschool education..... more power in lighter car equals beter power to weight ratio.. do u got it or do i need to break it dwn barney style? remember THINK before you TYPE..... ohh and by the way great buid guy! u did an exelent job!
prototypeuk u truely r the bigest idiot ive ever seen...r u a retard? really!! think before u type!!!! the lsx only weighs bout476 bounds with the fluid in it..give or take a few pounds, and how in the HELL would it throw it off balance? please do tell!
Totally. That is criminal to put a V8 into a RX7. I own 3 rotary powered cars and none give trouble plus my FD RX7 produces 320BHP and the engine has never been apart in its 16 year life
LOL criminal? Why? Because you don't like that it is way faster than your car?
A STOCK emissioned LS engine through catalytic converters produced 345 h.p. and 350 ft/lbs of torque back in 1997. This engine now probably produces over 150 more horsepower and torque than your engine as it sits. The only thing criminal about his swap is that this will be the first time in the car's life that the owner is able to get speeding tickets.
LOL...you are a real moron. The engine has already been proven over and over and over again since 1997 in vehicles weighing more. In addition there are many documented vids and forums of Rx7s with V8s running both quarter mile and roadcourse. You are just too ignorant to educate yourself.
I hate when guys tear the rotary out of an rx7. I just wish I could arguee with them. The rotary was a unique and amazing engine! And, in my opinion, as long as they are willing to acknowledge that fact, then do whatever you want with the car. It's just a car.

Its not an improvement because mostly down tracks you see v8's getting destroyed by Rotary's.
You see more better improvement in Rotary's than v8.
V8 guys just go on and here what they here the best .
Better torque, better power-curve and more mile-per-gallon than the "oil-burning", torque less 13b with only 30 extra lbs after swap!
Rotary's might not have all that, but surely it will destroy you.

ROFL. the standard V8 motor... in what year 1970?
standard for a V8 now is well over 400hp. whats the most you can push out of a puny boxer motor in a WRX? rofl.. exactly. Physics>you
millions of videos? really?
because its just common knowledge that a V8 with similar mods will ALWAYS outdo a 4 banger.
and i am one to know, so dont argue that.
dckmn52 2 years ago
THere are MANY WRX owners out there making 900 + HP on PUMP GAS.
Show a single STANDARD V8 powered car with 400 hp.
I was trying to be nice man, but you are utterly full of shit, and have ZERO idea of what you are talking about.
You are just spouting random bullshit, with no facts or research to back up your claims.
circutracer150 2 years ago
Chevy Camaro SS. Pontiac G8 GXP. Corvette/Corvette Z06. 6.2 in the GMC Seirra/Chevy Silverado.
All I can think of for now, but my point is clear. You sir are a retard.
DeftonesFan867 2 years ago 3
900hp? maybe but not on stock internals or stock turbo. v8s have clearly gone over the 400hp range and do it without boost or reliability concerns. and the weight issue? i doubt it All LS engines are aluminum in cars and dont weigh that much. its clear you are the one whos full of shit
thehowl666 2 years ago
No, the point was that the BASE V8 engines in cars today do NOT make that kind of power. Only the higher end models. Unless it is the "base" engine on an ultra high end model of that car or truck.
circutracer150 2 years ago
and i suppose the sti has a base engine? no. the base rngine would be the wrx engine which only has like 240 or 260 something like that. the sti has 300 and that car goes for like 35 grand. even a 2002 camaro z28 or ss had over 300 and they only cost like 25 or 27 grand
thehowl666 2 years ago
They had that on the CRANK, but nowhere NEAR that much at the wheels, and coupled with shit suspension, it was useless.
The entire argument started because it was stated that NO import could reach the power level of a V8, and that is utter bullshit.
And for the record, I own a 1967 Plymouth Valiant with a 360, .30 over, mild cams, 4bbl, race exhaust, and numerous other mods.
circutracer150 2 years ago
well i agree with you but people love to bach american v8s. in reality there pretty damn good engines. as a matter of fact the most powerful streetable engine currently is an lsx that can support 2500hp and still be streetable. oh but dont put that in the valiant by the way keep it old school
thehowl666 2 years ago
Of course they love to back them, but the tech is quite old now.
I say leave the classics in the classics ( like my Valiant) and put new tech in the new.
I cannot see paying 50 grand for a car with 50 year old technology.
I understand the appeal of american muscle, but I also know the extreme ferocity and quality of many of the imports!

They DON'T rule.
V10s make more power, and V12s, and MANY 6 cylinder engines make GOBS of power without boost.
I LOVE the bored out 360 on my Valiant, and make 443 hp to the wheels with E85, but I get roasted by all types and makes of cars.

I will tell you where the rotary engines are that run that fast. They are in the shop being rebuilt all the time as they are glass engines. While the V8s are out running, the rotaries are getting rebuilt. Obviously circuitracer150 doesn't know anything.
aji8 2 years ago
Rotary is junk..Those guys are lucky if they can make it that day racing without a rebuild or spare engine.
aji8 2 years ago
Poor guys on the street trying to drive their basically-stock rotary fast and not doing maintenance is what kills rotary motors. Engines always get rebuilt in racing... because, if they're "racing", they're running the motor at it's ragged edge of reliability - even V8's. Take a trip to an ALMS race and see what goes on in ALL the pits.
So much misinformation on here. Nobody has an eyewitness experience. Internet rumors FTL
Aerosmith145 2 years ago
LOL..here we go with the blame again on the owner. I guess the rotary is the perfect engine and will last 500K miles and put out 5000 h.p. You are correct about misinformation though. I suggest you heed your own words.
aji8 2 years ago
I said "ALL the pits".
Jesus Christ.. Where did I say it will last 500k miles and make 5000 HP? No where?
Oh ok, you're just an attention-whore fucktard.
Wait for his next worthless post... wait for it... wait for it...
Aerosmith145 2 years ago
There is such a thing as implied. All is for defense of the rotary, it can do no wrong, it must be the owner. That is the most stupid shit I have seen.. Keep it up moron.
I hope you have a rotary and it blows, which it will do. Eventually.
aji8 2 years ago
Ka-ching! Worthless post! I'm so good..
"it can do no wrong, it must be the owner." - what aji8 claims about piston engines. Implied, of course. Ironic.
Wait, is that him coming back? For revenge? Noo!!!
Aerosmith145 2 years ago
Yes you are good, good at being a moron. You still haven't proven a thing except you are no different than all the other idiots that reply.
The rotary is garbage, get over it.
aji8 2 years ago
Here's something for you. An american V8 longblock has 99 moving parts to wear out. And they all DO wear out eventually (remember, just like ALL engines).
A rotary has three. They wear out also, of course. All machines do. Don't even think about twin cam V8's..
But in summary, aji8 has a vagina if he replies.
I'm going to the lake. Have fun.
Aerosmith145 2 years ago
Here is something for you. You are an idiot. Just because one engine has more parts does NOT mean it wears out sooner. The same can be applied to OHC / OHV. According to your skewed logic, the OHC should have a much shorter life. WRONG!
The rotary wears out prematurely compared to the piston engine due to its DESIGN. I would like to know where you retards get your information. Must be fantasy land. My car with 140K was on its second engine when I bought it.
aji8 2 years ago
A 13B N/A makes 130 HP/liter. Apply that to a Rustang 5.0.. 650 HP. How reliable do you think that would be?
I'm a mechanical engineer, and love all engines, but for someone to say that an engine the size of a basketball that can put out in excess of 700-800 HP with 1.3 liters of displacement, is a bad design, just befuddles me. People don't appreciate innovation.
I'm only replying to these off-topic comments because I'm bored. I hope you're the same; or I feel for you.
Aerosmith145 2 years ago
Actually the 5.0 would be quite reliable boosted.
You are NOT a mechanical engineer. You don't know how many rotards I run into that are self proclaimed engineers. If anything you are a bullshit engineer.
Proof is in your post as you would not question the wear of the rotary. You know nothing except how to lie.
aji8 2 years ago
I actually am. Ever heard of a little company named Elan Motorsports based out of Braselton, GA? I got my Bachelor's from Georgia Tech and worked on the design team for the 2008 Panoz DP01 Champ Car. I've got all the CNC suspension parts and CAD parasolids to prove it. Do you just like to argue?
Aerosmith145 2 years ago
Oh really?! and how can you prove this? Moron. Anybody can say anything on here. What we need is proof. All I see is still words! If you knew 1/4 as much as you say you would not have questioned the venerable 5.0. You have no clue thus you must be lying. Next you pulled hp/L into the discussion and anyone knows that is a ricer statement.

@subaruracer107 well if you think about it a somewhat big turbo pushing low boost not working to hard would really boost the mpg if tuned right... :p and i like the PFC standalone for the 13b... can have 4 different tunes :D

"Here's something for you. An american V8 longblock has 99 moving parts to wear out. A rotary has three." Hmm! Let's examine this a bit more in depth. In the V8 when one part wears down for what ever reason the burden is then spread through at least most of the remaining 99 parts. spreading the decrease in efficiency rather vastly diminishing it through every part. Now when 1 part on the rotary wears down then that inefficiency has ONLY two remaining parts left to share that inefficiency.

Wow Not very Adapt at determining the purpose or which side an argument is taking are you?
AcomsRazor1776 2 years ago
Rotary engines may be a 1.3 but they do consume fuel equivilant to a much bigger engines and they use up more oil as well, if your going to have a rotary engine, you have to prepare for the constant maintenance it needs, the WHOLE engine needs to be replaced after 60k miles, oil needs to be changed every few months, there is no denying it is a very very smooth engine but people do replace them with chevy v8's because that engine has been around for years and its become a lot more reliable now

LS1 is best thing to ever happen to the RX7...
Better torque, bettter power-curve and more mile-per-gallon than the "oil-burning", torqueless 13b with only 30 extra lbs after swap!
Hows this not an improvement?

So you put in an LSX block.
Holy shit!!!! Thats over-kill. That block can survive 2500 hp. How fast you looking to go?

originaldriver 2 years ago
Still waiting 2 see a LSX Honda with a RWD conversion, but i guess 2 many people R busy putting LSX motors N places like an RX-7 where they don't belong. What about a LSX Silvia or LSX Skyline!!! Hell Y not a LSX Ferrari that would be a huge upgrade from that slow ass V12. If u don't like rotaries then stay away from RX-7's please so those of us that do like them have a place to put them N CARS DESIGNED FOR THE ROTARY.

It's possibly the LSX-block, which is a very expensive motor. My buddy has one in his F1-procharged Z06 and he pulls 1k-hp out of it. the LSX is one of the few or the only small block that can be bored to 500-cubic inches.

LOL criminal? Why? Because you don't like that it is way faster than your car?
A STOCK emissioned LS engine through catalytic converters produced 345 h.p. and 350 ft/lbs of torque back in 1997. This engine now probably produces over 150 more horsepower and torque than your engine as it sits. The only thing criminal about his swap is that this will be the first time in the car's life that the owner is able to get speeding tickets.
You can keep your weedwhacker engine rotard.
