Default just bought an my02 STI (from sydney Australia) - Needs an engine rebuild.

Hi Everyone,

just purchased an my02 sti that sadly requires an engine rebuild. Its currently at a performance shop and got qouted 4k for the full rebuild and installation.

My question i guess would be what i should do to it while the engine is out in terms of mods. Performance wise.

I do feel that the 2.0l engine without boost is not that powerful. So could anyone recommend a smart path to modding this so that it has better low end torque and overall better pull? I dont want to boost it like crazy or add an extra big turbo to it to achieve ridiculous HP numbers as i do plan to daily drive this. I would like to somehow keep up with my mates r34 GTR but remain civilised and easy to live with.

Any suggestions from previous experiences etc.

Since this is my first wrx or turbo car in general i would just like to pick everyone's brains here in the smartest and most effective path to take while doing this engine rebuild. I dont want to destroy the engine or anything either so i do want to be careful.

Also does it require a tune regardless after all this work is done? I hear its another 1k for tuning regardless of where you take it.

Thanks guys in advanced. Really appreciate everyone's thoughts and suggestions.

Been saving p for this car for 10 years and finally got her - but want to do it right.

Cheers,
M

open source custom dyno tune...probably around $5-600.
a quick search on this forum or google will probably point you in the right direction.

the section you're looking for is the factory 2.0L EJ series motor forum. just an fyi many reputable us tuners will e-tune your car over the internet. it does help if you have access to a dyno though and a laptop or accessport.

On a serious note, always get a tune. I don't care if the car is stock, a tune will make your car more reliable.

In Aust most tunes range from $600-2000 depending on which state you live in or what tuner you take to in Aust.

For $4000 a full rebuild? sounds like they are just going to buy a v7 sti short block, re-use your head and put it back together. Those blocks are strong and handle decent power (250kw easy with a good tune). I would recommend that use better head studs like ARP 2000 or ArP 625+.

If your in Sydney, then you should contact MSR at Michael South Engineering. His one of the best if not the best with subie builds and tuning.

Consider going for the 2.5 L bit more off boost / lower rpm power

You say you want to address low-end torque through potential performance upgrades. Consider a stroker engine during your rebuild. Can't hurt to talk to turner about it.
