Yes the EJ25 does bolt up to the 5 speed tranny. Now are you just putting the STI shortblock in and using your 2.0 heads??

Question

im looking at swaping the whole motor. ive found a few on ebay that was a complete sti motor and i know that they have the 6 speed trannys but all i want to do is just buy the sti motor and bolt it up to the wrx stock tranny. also off the subject i thought the ej25 was the 2.5 wrx motor. are the sti and the 2.5 the same motor???

my bad i just read off of edmunds.com that the sti is a 2.5 motor. now that i know that wouldn't it just be smarter just to buy a stroker kit for the 2.0 and get it tuned. there around the same price if your lucky

2002-2005 WRX's are the EJ20 motors, you know thats going to be a huge headache to put the STI complete longblock in your WRX right? your better off getting a STI shortblock and using your 2.0 heads to build a really nice hybrid, if you dont your going to have a wiring nightmare and what not.

ok thanks a lot. i may just look into a complete wrx ej20 motor with low miles. mines got 120000 and i bought it at a good price. ive read up that some tuners push pass 200k with a built motor but it would be nice to have one with less miles.

I would still go with the hybrid motor, those are great motors, just go buy a new STI shortblock and throw in some Forged pistons and get your 2.0 heads redone and throw those on that STI block.

would the newer wrx motors that are in the 2009 wrx work as a complete swap. i noticed that thoes are 2.5 motor. i got a response before when i asked about swapping a sti motor in my car and i was told to build a hybird build with a sti bottom and my stock 2.0 heads.will the whole 2.5 non sti 265 hp motors bolt up.

no the heads would still be a wiring nightmare...because they have AVCS so for them to properly work you would need the 09 ECU and Wiring harness also and probably a few other things im not thinking of

Unless the 09 wrx is also dual AVCS, wiring shouldn't be that bad. All you need is a new engine harness and ecu. If you use a jdm ecu you won't have to deal with DBW.

WRXKidid775 is more helpful than not
They will al bolt up to any tranny. The sti motor is the EJ257 the wrx 02-05 is Ej205 iirc. The 06+ is a 2.5l but its not the EJ257 from what i have read.

Will you run into the problem of the stock wrx transmission not being able to handle the hp of the sti block? or is that what makes the hybrids nice to work with? wrx transmissions are said to only hold up to 300hp... and sti motors push more than that.

It's how you drive them.

I'd switch out the tranny as well if I did a motor swap.

it would make sense to do that, but the problem that we run in to is the cost of the sti transmission...
