If you want some quick turbo power, look for an old EJ22T there reliable and they got a little bit of pep and wont break your bank.

it would be me more moeny for the ej22 i think. just cause the wiring and your going to an older engine and what not.

go with the newer sti, and your gonna have to do some stuff to it to make it work.

as one of the most experienced users on this forum

DO NOT PUT A EJ22T in an 08 2.5i
it will not end well and/or probably even start

the people above fail to realize how different the 08 is from pre 05 cars

things like:

can bus dash
vss via can from the abs module
immobilizer
throttle by wire

i believe the hvac is even integrated in to the can network

like i said above you would need a complete wrecked 08 sti


abandon this idea alltogether

I am a BMW technician. When you say bus, you are talking my language. There is some extremely high tech stuff going on in your 2008 buddy... I could recommend putting it on boost?

Save your money, trade it in, buy a car that is equiped with the correct engine.

I don't understand where people keep getting the notion that the 2.2 is the best motor out there, it's a 14 year old engine.

it prob has something to do with the old wives tale of it being able to take omega phat levels of boost when in reality its not really much stronger then a semi closed block

I've been seeing quite a few threads like this lately, just like the infamous "Will an EJ20H/R/8 TT motor fit in my LHD Impreza?".

Please just trade the car in and get a WRX. Swapping an 08, no offense, is the worst idea I have ever heard. I don't understand why people kill the resale value of their extremely brand new cars by messing with swaps. The big reason why people do engine swaps on Subarus is mainly because the pre-bugeye GC8 chassis Imprezas never saw turbo motors in the US and because bugeye guys want STI power since there was no bugeye STI offered here either.

When there is the same car with several different trim levels including WRX and STI from 04-08, it just doesn't make sense to swap it, especially since swaps cost $$$$ (Not cheap at all, especially when done correctly), and after everything is said and done you've exceeded the cost margin between the 2.5i and the slightly more expensive WRX. Sure the insurance will be cheaper on an 08 2.5i versus an 08 STI, but the fact is that you're going to spend somewhere between $10-12k for a proper STI swap with the 6 speed transmission to handle it, plus labor if you don't know what you're doing, which on an 08 I don't even think the pros like ECS and GT have even attempted to swap one, so it'd be uncharted territory and certainly expensive, given the complexity of the 08's in the first place.

And I don't know who recommended swapping an EJ22T into an 08, but you guys are NUTS. EJ22T not only is 14-18 years old, not to mention OBDI so you'd fail emissions immediately, but junk compared to the newer offerings. They are glorified because of their closed deck short blocks, but in all honesty who cares if the block will handle 30 PSI when the vast majority of people never push it past 20 PSI anyway, and the internals are junk. While the block halves will handle 30 PSI, the rest of the motor will not, at least not for long.

Some horrible ideas are being thrown around in this thread. Trade the car in or sell it outright, especially if you have more money now to buy the car you really want, which will also have the benefit of a warranty in case something goes wrong, unlike tinkering with swaps, which will certainly void any hopes of Subaru helping you out should something go wrong with your car, and things will probably go wrong at some point, as a swap is a constant tweaking process.
