Has anyone tried putting an EJ22T shortblock into a v5/6 type setup? I'm just curious if that would be worth it.

Nope not worth it. By the time you buy pistons and rods you may as well bought a Ver 7. If you are making 150hp/L that extra .2L is worth ~30hp.

Why would you need new pistons and rods? Aren't the ones that come in the ej22t short block good and forged?

yeah,
They call it a 22B replica...

That's sort of along the lines I was thinking...I just wanted to know from someone who has personally done it what their opinion of it was.

I was thinking adding the ej22T to 5/6 heads would be like a wrx 7.x:1 cr.

I've seen a lot of information on people doing an ej22t with stock heads, wrx heads, ej25 heads, ej22 na heads, but I can't find anything about doing it with version 5/6 STi heads. I'm seeing a lot of conflicting information--some say it cna hold insane amounts of power, others say it's not that great.

I was thinking about putting a version 7 into my GM6, but I saw EJ22T crate short blocks for sale and was considering the idea of saving a little money by putting an ej22t shortblock in a version 6 engine.

And doesn't the US WRX have 8+:1 cr?

The ej22T is an old phase I block and has cast pistons and the same rods as any other non Sti engine. It made 160hp stock, not like the fodged piston 300+ hp 22b. There was one on ebay with bent rods at a little over 300hp. Since the block is a closed deck it has the POTENTIAL to hold alot of hp. You wont be making that kind of power especially on stock internals.

"yeah,

The ej22t can take more then a wrx block... and has been known to take very high levels of boost 20+psi for an extended lenth of time. IMO it is a block that realy would be best if you are planing to build it up (new rods and pistons). The wrx heads are ver 5/6 castings, some of the ver 6 sets had larger ports, so the CR will be the same as the wrx heads 7.7 to 1 IIRC. Its just too low... if you are only going for ~300hp then just go with an ej257 short block.

Clark at subaruwrxparts.com told me the ej22t crate short block they sell indeed has forged internals. Are you sure they're cast?

edit: the faq says forged rods and cast pistons. I guess that puts it somewhere in the middle.

Scoobie Steve,
I think 22B replica is an appropriate term, though I should have dropped a :rolleyes: because I was being sarcastic about yet another 22B wanna be thread. It is not the same as a 22B block, but there are some similarities that make it very worthy to work with, as we already know.

And the EJ22T does have a forged crank and rods. The stock parts on that block are very good parts. I personally think the phase I vs phaseII is way overplayed. It matters when looking at using an NA EJ25 for a turbo build, but not so much on a closed deck turbo block. A number of our members have shown that if you put a stock EJ22T into your car you can make huge numbers with it, and reliably.

The lower CR with WRX heads isn't really an issue if you run a big enough turbo on it. A vf-22 is about the minimum that you would want to use, and something like an 18g would be even better. And if someone is really hung up on the CR, they can get a set of CP forged pistons from Axis that will bring the CR up.

But unless you can find a set of v5 or v6 heads for sale by themselves, I do not see the point of such a build. If I have a fully functioning v6 longblock, there is no way in hell I would tear the thing apart just to get an extra .2l of displacement and the ability to call my car a 22b replica

You wouldn't even tear it down just to get a closed vs. open block engine instead? What about putting a ver 3 block into a ver 6 engine?

No point in that unless your looking to run something like a gt35 or bigger and 30+psi and 500hp. More then you whould ever need in a street car... and more then most people would ever spend. Closed vs open means little in the real world... its only when you get to the stupid levels of power that you would think about that.

Very true there are a number of tuners and builders that like low CRs and high boost. You could run a 20G, gt287 or a small GT30 and have a very nice ca.... but I like a more responcive car.

ok, I see. I guess I'll just stick to the ej207 idea

Matt i do agree the phase I,II may be slightly overplayed but i have pulled apart more then 1 high milage ej22t 5 speed that had almost a 1/4" of crankshaft endplay due to a shot thrust bearing. If you plan to built a high hp engine with a heavy pressure plate a phase II block is a good idea. IMPO the 2.5l STi block is a much better choice then the ej22t

If you replaced the cast pistons with forged ones with no dish or possibly a little dome, won't that get the cr up to where you want it? Then you have a little more torque on the low end and still push the 8000 rev limit. It would probably be easier to get a 2.5, but I'm just sayin'...

Ya, you can get custom speced pistons to just about whatever CR you want.

didn't I say that like 10 posts back? :confused:

Ya... pretty much.And if someone is really hung up on the CR, they can get a set of CP forged pistons from Axis that will bring the CR up.

Just checking since he asked the question after I had already given the answer. ;)

I was... confirming. Merely confirming. Yeah, that's the ticket. ;)
