hi all,

Im planning future mods one my new clutch, flywheel and gear box is fitted within the next couple of weeks. I would like to reach 400bhp or around it.

So far im around 300bhp what other mods would i need to reach as close to 400bhp as possible.

ive got 1993 wrx import with,

power fc & commander & andy f remap
decat
apexi induction kit
440cc injectors
walbro fuel pump
fmic
99/00 wrx import gearbox
lightened flywheel
exedy organic clutch

I know ill need to get a bigger turbo and injectors but what size? and what else do i need. There is someone selling denso purple 550cc injectors at the minute would they be anygood.

All info is welcome

would go bigger than the 550 to be honest to give yourself more headroom. I think at 400bhp range you will seriously need to strengthen the bottom end (forged pistons etc) to have and chance of reliability.

Whats the closest to 400bhp i can go before i need to fit new internals

About 320-340bhp at most I would have though... depends how well its mapped... and depends how long you want it to last???

I would diffently be gettin andy forrest to do the mapping again was hopeing though i would be able to get more than on stock internals/

I think 350 is the limit on stock wrx internals, be cheaper in the long run to get forged internals and start from that

did andy f not have stock internals on his 440bhp wrx ra. I know his was a 2003 but are the earlier import internals abit better?
