#06 255hp CONQUEST TSi[1UZ-FE(4Litre V8 DOHC)] on the Dyno

[Listerfiend808]

Looks like an AE86..

[woodgrain18]

I am in the proces of buying a 88 starion and have a 4.8 ls truck motor i want st swap in with a turbo 350 but i cant find anything on that kind of swap  i kno it can be done if that 1jz went in one

[CheesePhantom]

Good job, man. If you ever want to make it a manual, check out Quantum-Auto.

[Mrinfoone]

what engine type and from what model car.....year? Did you have change any off the suspention or tranny? Please be very specific in describiton of the modifications...thxs.

[itsmister2u]

i always wanted one of these cars. a girl i liked (who never liked me back) had one of these in the late 80's. her father got it for her. i believe it was turbocharged.

[Bluphyre1]

Conquests and Starions were not considered DSM (Diamond Star Motors) cars. The Laser, Talon, and Eclipse cars were DSM, as they were manufactured in Normal, Illinois. "Starquest" cars were imported from Japan.

[onet1me2007]

i need some help finding parts for an 88 tsi. shit is driving me crazy 2.6 is said to be a peice of shit but i wanna build it strong any suggestions other than swapping the motor would help.......please help

[sugarisgoodness]

fucking brilliant combo

[87V8Dakota]

That sounds bad ass.

[headbangerlover]

u all know nothing more than shit.

[jamaicanlovrboy]

Nice swap man now if u could fit a pair of turbos on there :D

[thevyris]

sts- rear mount turbos would be cheap and nice

[cbamode]

japan > all .nuff sed

Apparently you've never heard of rod stroke ratio... Stroke has very little to do with RPM limit. It has far more to do with the angles of the rods in relation to their stroke. Longer rods, in relation to stroke is key not the length of the stroke. And no hands down any LS series engine beats 1UZ.

[787Bisurdaddy]

Apparently you've never heard of piston speed, or reciprocating weight.

[Kornball426]

I have and typically you're not supposed to pass about 5000+/- a feet per minute if you want any kind of life span to your motor (for the street). If you talk race, and wearing out isn't important you're just limited to how much stress your parts can take before breaking. Point is over 8400 RPMs is were you pass the 5000ftpm mark in a LS1. It'll do that all day long, make more power than a 1UZ & weigh less doing it. AND have complete aftermarket support for as much power as you could want.

[787Bisurdaddy]

Bench race much? Seriously, how do you pull such a number from anywhere but your ass?

The point is that reciprocating weight has every bit to do with revability as rod-to-stroke ratio. An example would be the 9000+ rpm Honda engines, which all have less than the 1.70:1 ideal RTS ratios.

[Kornball426]

Reciprocating weight has far more to do with how fast you can go up and down through the rev range not how high it can theoretically rev. A heavy rotating assembly doesn't mean it can't rev high as long as it's well balanced, it just means it can't rev as quickly. And wtf are you talking about? It's easy to calculate piston speed & it's pretty well accepted that 5000 ft per min is about as fast as you want to go if you want a motor to last. LS1= 3.6in stroke, 8400 rpm = 5015ft per min.

[787Bisurdaddy]

I'm baffled by how you think heavy pistons changing direction 250+ times per second couldn't possibly place additional stress on the engine.

"It's pretty well accepted," well I guess it just doesn't get vaguer than that, huh? First you were talking about rod-to-stroke ratio, and now you're talking about piston speed. Which is it? Rod-to-stroke is a factor in piston acceleration, not speed. Rod length doesn't even come into play in calculating piston speed.

[Kornball426]

You're the one that brought up piston speed and rotating mass. If you didn't have ADD you'd realize I was addressing your comment, not changing my statement. I've built engines where piston speed was critical, it's a general rule don't go past 5000ftpm or you'll experience excess wear on pistons. LS don't have this problem because like I said 8400rpm is 5000ftpm and the rotating assembly isn't that heavy, the stroke isn't excessive, and they rev just fine. So, you're wrong... The end.

[787Bisurdaddy]

You brought up rod-to-stroke ratio, saying that stroke had very little to do with RPM limit. I brought up piston speed and reciprocating weight, since rod-to-stroke ratio really only affects piston acceleration and side-loading of the cylinder walls. Your argument was that rod-to-stroke ratio affects piston speed, which it doesn't. Piston speed is an average; you were talking about piston acceleration.

[787Bisurdaddy]

Furthermore, you said:

"A heavy rotating assembly doesn't mean it can't rev high as long as it's well balanced, it just means it can't rev as quickly."

Engines are constantly accelerating and decelerating. So quick revs are very much key to maximizing the performance of an engine.

And you claim that excessive RPMs cause wear on the pistons, but that's not the case either. RPMs stress the rods, not the pistons. Piston wear comes into play due to side-loading regardless of engine speed.

[Kornball426]

What are you a moron? Piston speed over 5000ftpm as a general rule of thumb, causes excessive wear. Depending on the stroke of your engine, you can surpass that speed at a certain RPM it's a fact. Rod stroke ratio(rsr) effects rpms because you'll break a piston or rod in an engine with poor rsr if you rev to hard, which depends on a shitload of factors so that RPM can't be said for certain it's different for every motor what with metalurgy, lubrication, heat, balance, internal tolerances, etc.

[787Bisurdaddy]

Repeating yourself doesn't make your statements any more correct. I've already mentioned the fact that there are plenty of engines with a worse rod-to-stroke ratio than the LS1 that can still rev higher, so I'm not sure why you're still going.

[Kornball426]

Well then congratulations on stating the obvious; "there are engines with worse rod to stroke ratio that can be revved higher than an LS1". Was that your whole point?

[787Bisurdaddy]

Facepalm.

[himynamesjoe]

something isnt right. 255 from v8?????

[toyssan1]

a completely stock 4.0 v8. 255whp is about 320 at the crank. Not bad for a little 4.0 that probably gets 27mpg+ in that patictular car.

[kfrede9]

A similar year ford 5.0 put out an amazing 225hp at the crank! Thats comes out to a shocking 187whp if you figure 17% drivetrain loss.

[funguy7979]

its just poorly tuned from the factory. Remember that the lexus sc's from the 90's only had 270hp and 250tq from the factory and that was a 4.3liter. If you tweek it a lil and maybe throw in a more aggressive cam you'll have 300hp in no time.

[MKIIIBoy]

They all had the 4.0 till the SC430 convertible thing came out. But I may be mistaken.

[ARandomCanadian]

Oh they just put a Toyota engine I see

[ARandomCanadian]

Why does he have a dodge steering wheel cover? lol

[duanedragon2]

Wow, it's like the Japanese reinvented the 1986 Ford Mustang.

[turbillb]

Not only did they reinvented the 1986 Mustang, they released it in 1984.

[jeffgooloolie]

Wow, 255Hp from a V8! THATS HORRIBLY LOW. You could have gotten 255HP from the original 4 cylinder with less weight.

[DoriFord]

dude, you know... that V8 pulls 450 hp with 1 bar... plus it weighs 190 kgs... do ya know how much does weight an SR20DET for example?.. then count..

[toyssan1]

that is 255whp, not hp. Would be like 320hp. And only a 4.0. Some people!!!!

[zpunout]

Did the car have a speed limiter thing happen at 4:40 and 5:55?

[4x4Explorer]

man i love how that shifts.. great sound

[Ktrain0218]

I guess its also a Mitsubishi Starion

[DoomiteAsh]

That Lexus V8 sounds absolutely badass! I saw a Conquest TSi for (I think) the first time today. Not a bad looking car at all. And with the sound (and potential) of that V8 under the hood, I'm truly impressed.

[TRUENOGTAPEX1600]

wtf? why didn't they use a jap model starion instead? y they gotta take our damn conquests! lol

[DThompson1985]

They are the same cars. The only difference between the two is the Name and the front grill is black on Starions

[Chromedragon79]

The 1uz is one of the most overbuilt V8s ever made. Six bolt mains mean you can leave the bottom end untouched as you run upwards of 1,000hp. No LS1 engine will ever rev like this either.

[ZechsSetsunakute]

I have that engine in my LS. Great engine and unbelievably smooth and quiet for a V8. But it's a bit thirsty for petrol and runs only premium octane.

[intheshitter]

Nice. Massive improvement on the rattly ass g54b.

[Zrider87]

1uzfe can have potiental of up to 2700 hp @50 psi...don't underestimate =D

[MichaelVannoy]

I wouldn't waste my time with a g54, by the time you jam 4-6 grand in the engine to make it do anything you could have stuck a LS-1 and have reliability.

[SidewaysGts]

Why would you jam 4-6 grand into the g54? You can get this kind of whp on a starion with minimal work, good turbo and exhaust with a boost controller is just about all youd need.

[slaughterofthesoull]

lol ls-1 = bad power to weight ratio, its a heavy peice of crap pushrod engine..............

[Kornball426]

You're retarded... Look up how much an LS1 weighs I'll bet you it's less than a 1UZ or the original motor out of this car. And there's nothing wrong with pushrods, it's a lighter more compact setup than OHC's. Plus they rev just fine with roller rockers and lifters 8000 rpm is no problem at all. I do over 6500 on my stock 4.6L chevy all the time... That's the "redline" on a 1UZ and most Jap V6's and V8's.

[timwashere]

ls1 weighs 15kg more than a 1uz which is bugger all in the sceam of things and you get another 1.7 l

[cool00bananas]

with all the accesories like powersteering pump altenator etc a ls1 is 201kg and a 1uz with the same parts bolted on is 223. the 1uzfe is heavier because of the OHC

[toyssan1]

Kornball, you don't know what you are talking about. A stock bottem end 1uz can handle 1000+hp and 10,000 RPM. Readline at 6500 does not mean that is the capacity of the motor. Upgraded valvtrain will easily take this motor to 10K. 1UZ has a stroke of 82mm where as the LS1 is about 89mm. Which one do you think can rev higher?

[DrWonderEyes]

255 hp thats all?

i'd rather work the original engine

[slimeball6969]

g54b is nothing special

[chrisutubecom]

Excellent video! I just bought a V8 car art poster from cartech49 dot gr. Great fun art for my garage wall!

[greenbrassplaya]

what rims and tires are those? not asking g63b111kw

cause honestly all he knows about on this vid is the engine (no offense in any way its just what you said)

[ca18s13]

hi :)

do u have a workshop in japan that specializes in starions?

if so are they rare to find in japan and why do u concentrate on the mitsubishi starions...

thank you

[sfbmx88]

No. The Starion and Conquest were never DSM. They were pre DSM. If you read the Conquest badging, they always say "imported for dodge/chrysler".  Conquests were never assembled in the United States.

[prozbo1]

beautiful wheels..!

[streetroyalty1]

I was wondering,,, were those considered DSM's?

[g63b111kw]

What's mean 'DSM'?

[casmitherz]

That stands for Diamond Star Motors which was basically the US (Chrysler)/Japanese (Mitsubishi) partnership which started in the mid 80's. Yep the Conquest was DSM for sure. The Starion... I don't think so since it was purely sold as a Mitsu vehicle.

I had a perfect 88 Conquest Tsi... damn it was fast. Sold it to a buddy and he totaled it in 1 month, it lit on fire and everything! I miss that car :(

[saosin520]

@streetroyalty1 no only talons eclipse and plymoth lasers were considered to be dsms

[savagexhaley14]

@streetroyalty1 technically yes, but DSM commonly refers to eclipses, talons and lasers

[SEWegman]

@streetroyalty1 yes

[WindwolfBlog]

@streetroyalty1 Nope, they are not DSMs. Built in Japan, not Illinois.

[ls1fc3s]

i want more info on the swap im in the middle of the same swap

[g63b111kw]

Unfortunately,I donn't know detail about this car.

I know just owner has order swapping motor to the professional. I heard a story that work was really hard even professional mechanic.

Hope to successful the swap.

[ls1fc3s]

ok thanks if u run accross any more info on it let me know

[g63b111kw]

That exhaust is not genuin one.

4cyln to 1pipe x2 dual exhaust.

[tokyosmash]

Did he stall it on the dyno?

[g63b111kw]

No,they just setting up.

[808TurboedDragon]

hokie smokies bullwinkle. the 1st japanese v8 that i've seen in a starion or conquest.

[g63b111kw]

It's first japanese made V8 STARION.I guess me too.

[Tomvr4]

That is phat!
