not to sound like a dick but he has a good point if you needed to ask whether or not a t25 will work on a 2.5L you need to learn more. t25s run out of breath on the 2L's. i think you have a long way to go before your gonna sucessfully turbo any car

 

do the twin setup i wanna see how it turns out...

 

the guy with the t25 still hasn't answerd any of my emails, he said he would figure out shipping, then disappeared. I bought a t3 on craigslist and i am in the process of rebuilding it. This guy did a great job of completely DIYing a twin turbo set-up on a 325 cabrio

I do too. But buy a car first.

 

Too small of a snail for a 2.5l. I would get a suby turbo over that. Like a vf34 or 22!
