Default EJ22T in 2005 WRX?

I was wondering if a EJ22T would fit into a new 2005 WRX. I have seen the posts and it never says anything about new WRX! I have the shortblock of the motor (ie crank,pistons,rods,ect) and was wondering if it would bolt onto my tranny and heads and all the electronics? Can someone help me? Also I ahve no oilpan or nuttin would my 2.0L studd work?

you could swap the block itself, keep the heads and everything. then you wouldn't have to work with all the wiring and bullsh-t. I don't know what the compression would be... I don't think I have the numbers available to me for the 2005 2.5L heads.

Thanx guys! I also Have one more question! The EJ22T motor was it originally a SOHC? I was asking cobb tuning if they had any rods for this motor and they didnt. does anyone know who makes forged rods for this?

Work... ahhh... so tired.



As for rods and pistons look at crawford performance. It does have a very low CR on wrx heads and is a better block to build on. IE forged units, boring, ... If your looking for a bolt in ~300whp the ej257 is the best bet.

Yeah...do a search in the conversion forums- if it fits in any impreza it'll fit in the new ones too
- SOHC indeed, I'm bolting up the EJ20 heads with ARP studs and Comteic gaskets.
- Compression will be somewhere around 7.5:1 depending on the gasket you use and the exact distance to DTC the piston comes to the deck (clearance) and if you do anything to change the CC's of the heads.
- Oil pan will swap over yes...use the EJ22T oil pump tho: more pressure (prob for oil squirters found in it)
- The 91 came with an oil cooler (on the pump kinda thing) aka the same as the WRX does now so worse comes to worse you can use the WRX one and shim it or just buy a new replacement one for the 91 Legacy turbo and ur good to go.

I agree...if you want a quick and cheap boltup: EJ257...if you plan on more power or a good motor to build on later: EJ22T/E.

Good luck!

Thanx guys! Well I already have a EJ22T motor with Cobb tuning pistons that have coating, anodized ringlands, and titanium pins, hence the reason for the rods. Also I was just wondering whats a good head to put on these motors cause everyone on the conversion page is sayin the 2.5 SOHC and the regualr WRX Head which is he 2.0. I was wondering if the new StI head will fit. Also if im going to rebuild teh whole head like I did to the motor, should I just try to find a used wrx head, if so does anyone know where I can get one? Oh yea the block has been bored out to fit 90 mm pistons.
