hey every1 just bought me a 1991 pulsar gtir. in black with 17inch white inovit redline wheels. firstly i will post it spec and could u guys tell me whats good and what might need replacing. i also want around 400+ hp, at the mo its running 340bhp and 301ft lb torque.
only running at 1.3bar tho. right here goes
jic coilover suspension
tarox discs and ebc pads (first mod will be ap kit or hi spec kit, opinios pls.)

z32 maf, plus extras but the engine is the most important bit for now.
also 700cc injectors lol
what will i need to change to see 400+ bhp, i have a feelin just a new turbo and remap will get me there, apparently the bottom end is good for 1.6 bar. i think the turbo is the limiting factor. also who can remap the car who is reasonably close to me. (surrey)
cheers for any help guys and any other advice is apprieceted. cheers

like u say a bigger turbo like a gt30 plus a remap should see 400bhp plus,with the bigger turbo u should see 400bhp on the same sort of boost around 1.3 to1.5
