real quick question if a gt28 is fitted to a aum lump is it just a matter of remapping to get it to run properly
or wud the injectors or management need changing

map will have to be a custom live setup on rolling road i would have thought, and you would have to speak to whoever you were going to have it remapped with as to what they thought the best injectors are for the job   :smiley:

your looking at up to 400bhp right there.. you would need very big injectors.. SCAT rods.. bam pistons.. cold plugs.. a very good FMIC.. and loads of other bits and bobs.. also my friend has decided to strip his 2871rs mk4 golf as the 2 manifolds he had just kept cracking both of very very good quality but just couldnt withstand movement and heat.. your also looking at £500+ for some good mapping.. Nick at RTech can also set the ECU to back fire on gearchanges like the porsche and ferraris etc do which sounds awesome in real life..

Add a 4bar fuel pressure regulator and up rated engine mounts to that list. And a better clutch and LSD.
And better brakes.

What have you done so far and what exhaust manifold are you using?

Injectors will need doing but as tech said, its not a simple 'any XXXcc size will do. need correct spray pattern etc.

well for a start you need to change the rods... the standard bam ones wont take 2871rs boost for longer than 5 mins..
