What mod next 330HP 05 STi
 

Hi all.

Currently i have 05 STi with 3" Milltek and Remap done by PowerStation, they measured it at 326bhp and it goes well, still you know what it's like you always fancy that bit more.

I spoke to powerstation again the other day as i noticed they are now offering the MD555 turbo, but it would be a lof of money for 25hp or so gain, next step they were talking about was a FMIC, but i'm not too keen on going that route yet unless it really is worthwhile.

So question is what would you guys reckon, perhaps the 555 + ported headers? Or is the fmic a good option even at this modest power level?



I'm interested in getting up to near 400hp mark, but i'm not looking to open the engine up for pistons etc.

Choose a 400bhp turbo, add tubular headers, injectors and remap.

I wouldn't think about a FMIC unless you are doing much sustained trackwork.
