Subaru SVX Sleeved Block Resurfacing

[Mr2005wrx]

You can squeeze a lot of power out of turbo engines but it sacrifices reliability. Just look at the 1000hp/litre F1 engines of the turbo era or 1000hp/litre top fuel dragster motors. That makes 300hp/litre look easy!

[AlabamaCrackerHonkey]

John, I seriously doubt that you would be able to produce 1000HP from only 3.3 liters of displacement. Correct me if I'm wrong, but as a general rule, aren't most NA engines only good for about 100HP/1000cc and turbocharged about 200HP/1000cc?To make a 3.3 liter engine produce essentially 300HP/1000cc, you would need two turbos and I doubt it would be reliable.

[fiatnutz]

@AlabamaCrackerHonkey - The Offy engines produced upwards of 1200 hp in their day with a big hair-dryer and they were 181 cid and 4-cylinders.

[VeryTucker]

@AlabamaCrackerHonkey There are 1000hp sti race cars.... I think those use a 2.0-2.5 liters of displacement.

[nuckenfuts12]

@AlabamaCrackerHonkey Supras are 3.4 litres/3400cc stroked and they make well over 1000hp

[jgizzy]

Hey John, can you take a look at a picture of a recently machined B20A5 (Honda Prelude 2.0si) and tell whether or not the surface finish *looks* okay? To me it looks like crap, but since you're a professional....just wonder what you think. Thanks so much. (please remove the --- from the url)

[itchyundies]

your vids are fantastic priceless info for the layman and is this a 3 cyl 1000hp motor sheez must rev like reverand burn

[EG33SVXLSi]

@itchyundies its half the block. the SVX is a 6 cylinder. EG33.

[madafakades]

quite a good beard

[Maximusfool]

John when you say deck surface. I take it you mean block face ? Sorry the American termonolgy is a bit different to UK

[mbdulka]

If I send a stock EJ25 Subaru short-block to you, and you sleeve it, is the bore still 99.5mm like stock, or is the bore smaller after being sleeved? Alternatively, do you have any EJ25 short-block cores for use?

[fiatnutz]

@mbdulka - I can push the bore to upp to 103mm. I have EJ25 cores.

[mbdulka]

@fiatnutz What is the standard size after sleeving ... the stock 99.5mm? (I understand you can bore it to 103 .... but if you just remove the stock sleeve, and insert your own, is it initially 99.5mm like a stocker?) What is the price of your core (you can PM me if you want)? 1800 for the sleeve work (that includes the sleeve? Or should I buy some other sleeves and you can install them?) Questions, questions, questions.

[mbdulka]

@fiatnutz Hit me up on email John when you get time -- I sent you an email ;-)

[Ryoukun16]

Thought the engine was a closed deck like the EJ22 (Engine it was based on)?

[stampede1027]

@Ryoukun16 the ej22t was close deck.

the ej22 and ej25 are open deck.

[footyboyack]

good work John, that's a great design.

[lazzer408]

PRICE?! No one ever posts the damn prices. Maybe it's so high they don't want to scare anyone away.

[fiatnutz]

4 cylinder: $1800

6 cylinder; $2250

Includes: sleeves, installation, honing to size, surface block, and alignhone JE...

[lazzer408]

Ah now that is reasonable. =)

[mbdulka]

@fiatnutz Another question -- would you be against installing some third-party (Darton) sleeves instead of yours? And again, how much for the EJ257 core? Your work looks awesome!

[mrmichaelcross]

@fiatnutz thats actually not a bad price

[MrSkantron]

@fiatnutz So you would sleeve my vq35 hone it and resurface it for 2250? how much would it be if I provided you sleeves?

[AriesNSXS2000]

Ok I cracked one of my cylinders in my block.I just wanna know, If It can be sleeved? I mean I have the sleeves just not put in yet..i'm just afraid there gonna say I need a block instead of sleeving.Besides i'm going turbo.

[fiatnutz]

Who's sleeves do you have? The one's I designed replace the entire cylinder. My sleeves are a T-design and have a very wide sealing are for the gasket, and they are nearly 10mm thick.

[Xantex1995]

@fiatnutz

[marek0086]

hey John, why not use Steel liners ??

[fictioussentiment]

John-

I always understood a closed deck design to be better/stronger? For example, I'm always told that my open deck block on my 2.0 WRX is inferior to the semi-closed deck block on the 2.5 WRX or STi engine. I've also heard that one of Subaru's strongest engines is the EJ22T (2.2 closed deck engine). I like the idea that my 2.0 open deck gets better cooling, but is it not as strong for that reason? Because the the cylinders have more play and potential to warp or something?

[jgizzy]

All of your reasoning is pretty much dead on. Closed deck blocks are almost always stronger due to the nature of the design being that the sleeves are supported better so they don't flex and warp as easily. But an upside of an open deck block, besides it being cheaper to manufacture, is that the unobstructed coolant passage is able to cool the top part of the sleeve more evenly, which can have obvious benefits. A semi-closed deck block is an attempt at getting the best of both worlds.

[fictioussentiment]

I understand the semi closed deck blocks trying to live in both worlds, so I guess I can see why there is benefits to both. I just was always told for high HP applications, a fully closed deck is a better design to hold the power. I wonder what Porsche engines are for example...

[marek0086]

Of course closed deck is stronger..... u have reinforcement /support around the top critical area.

[fictioussentiment]

Would love to get John (fiatnutz)'s opinion on this stuff... but he doesn't seem to want to respond to my original comment or any of our discussion even though it's been 4 months now...

[marek0086]

well you're just gonna have to trust me.... coz i know what im talking about.

[subiemon]

maybe he just plain busy he runs a machine shop not a lay back in the chair job!!!!!!!!!!!!!!!!

[fictioussentiment]

Maybe, but he certainly has time to play around with videotaping his activities (to include cooking!) and manages to find time to post the videos to YouTube. If it's some kind of promotional thing for the company, why not respond to legitimate questions about the videos posted?

[subiemon]

uh ok did u not hear the motor is going to have about 1000 hp, i think he knows what he is doing!!!!!!!!!!!

[markeymark916]

4:36 ... probably the best PRO-open-deck explanation I've ever heard.

1,000 HP SVX!? Can you say SLEEEEEEPER! :)

[zapwatt]

I don't think it is going into an SVX. He said it was for an offroad vehicle.

[lazzer408]

I can say blown trans.

[AxSxKxONE]

yeah the feat trany is known for failing in the svx , if you have an svx and added more power you gonna need a 5/6 man swap

[57642J]

Nifty, very nifty, and oooooo I want a 1000 horsepower v6, pllllleeeeeeaaaaassseee?? =)

[Subarujoe]

flat 6* =] better haha

[EvanAxer]

Boxer 6, H6, Flat 6

[zapwatt]

Flat 6

[Bowtie41]

John,

Please explain what other equipment is in this engine to get 1000hp?Awesome!

[EvanAxer]

He didnt say it was a 1000hp engine he said its "GOOD UP TO 1000hp" so if no boost is added then it will be the 220hp that will be bullet proof. to get 1000hp you need like 25psi+ and ARP bolts all around. New H Billet Rods and lower compression Forged pistons, free flow exhaust, and a whole dyno mapped ECU. thats how you can try to get to 1000hp.

[oldboi1]

who wasnt talkin english lol but yh learn english

[oldboi1]

orite u cocky cunt i was asking because 3 cylinders shown and y only show it as half bit stupid and i asked because all the impreza's are 4 cylinder

[Paisley37]

learn your english some fuckwit

get engine smart

[bunnyluv1987]

can i sleeved my 99 subaru impreza

[2slofouru]

How is the steel sleeve connected to the block? Is it just wedged in and then bored out while in the aluminum block?

[marek0086]

the sleeves are 'press-fitted' into the block.....nice n tight

[SubaruXT6]

could this be done to any engine ? like the 2.7L h6 from the Subaru xt6. also could it made into a H8 ? I'm impressed with this video. how m,much would it cost to have this done ?

John aka Subaruxt6

[gdrozd555]

H8??? WTF are you talking about?

Your idea is beyond ridiculous. Unless you wanna do a whole new engine.

[SubaruXT6]

well if i could i would make a Subaru H8

[gdrozd555]

do you even know how the engine works?

Just because you theoretically could fit 4 sleeves per side, what were your plans for crankshaft (and mounting it) heads, timing, intakes, electronics?

Your idea is beyond stupid and would require a new engine to be build pretty much from the ground up.

[SubaruXT6]

yes i do. it was just a thought. not actually gonna do it.

[gdrozd555]

well, its a stupid thought

[DonKael]

Jesus christ, look at the water passages on that block! Even with the sleeves, I'm surprised that thing wouldn't warp.

[guyver280z]

Im pretty sure he said the engine came from an SVX wich is an EG33 but I mispelled with a J.

The EZ30R and EZ36 are the 3.0 and 3.6 that come on the Subaru Tribeca.

[guyver280z]

So any updates on this engine?? Im going to get a spare engine to work on it (or have somebody else build it) But I want a bad SVX, Im also going to swap an H6 into my frien's Impreza RS, so we are going to be around a lot of EJ33's.

[speedophile78]

it's an EZ33 not an EJ

[Einimas]

Huge sleves O_o

[Einimas]

What would hapen if you put a wrench on top of the block before you mill it?

[fiatnutz]

I'm not sure I understand your question. If you lay a wrench on the block w/o causing severe damage, I don't see a problem. If the surface is damaged, the gasket will not seal properly. If you can be a little more specific about your question, I'll try and answer it.

[marek0086]

what are these sleeves made from??....billet Chrome-Moly steel??

[colin340]

@Einimas it would get you like +12hp thats all

[stampede1027]

@Einimas it would be pushed off and gravity will force it to your toes. it may hurt

[bigrednumber]

Its only one half of a 6cyl.

Can you please show how the sleeves are made and fitted? I saw you have an STI block with the factory sleeves removed.

[oldboi1]

y choose a 3pot motor ?

[gdrozd555]

its a 1/2 of a 6 (pot) motor

they are called "BOXER" dumbass

[docrw]

They're engines not MOTOR's or as they are pronounced mowders

[thexrealxASK1]

nevermind i paused it at 06:02 / 06:29

[thexrealxASK1]

costa mesa research and development automotive machining does not exist , is it under another name ? cause im serious about getting my engine done

[thexrealxASK1]

a stock svx has around 260hp , so i want that block on my 92svx!! how much would that cost , im in los angeles so we are not far from each other

[Zryuken]

Incorrect. Stock eg33 makes 230hp.

[thexrealxASK1]

your right , only 30 off

[guyver280z]

I want to know how to make 1000HP on my SVX too????, 600 or 700 HP would be ok.
