Ver.4

Hi all, i have a sti5 type r and was wondering what mods i would need in order to achieve the figures in the next sentence. I previously owned an evo 7 running 356bhp and 353 lb ft torque and was wanting similar power figures from the scoob to see how it compares.

Within the next few weeks the car will have a full 3 in exhaust system with the original headers and up pipe wrapped and ported. It will also have a sports panel filter and an apexi power fc and commander ecu unit.

What sort of power can i expect from this and what will i need on top of this? Simple stage 1 from the evo gave huge gains but from what ive read, its rather difficult to extract reliable power from the scoobies

Any insight or advice will be much appreciated.

Thanks for looking

hi ver 4.
you should fit new walbro 255 fuel pump to be on safe side..you wont see anything near 356bhp tho, sorry to say.

You'll need:
ECU + mapping
Injectors (550's+)
Larger intercooler (newage sti or front mount)
Fuel pump
Bigger turbo
better exhaust
Possibly headers
Air filter/ induction kit

At that level you're around the limit of the gearbox. However, with the Type R's low ratio gearbox it makes for a rapid car.

As above list. Turbo a 18g billet perfect choice.

Oh and a upgrade clutch too.

would the standard ecu be upto the job just ECUTEK'd rather than have to pay out for the Apexi set up?
