hi just wondering what power i should expect out of this setup on a na motor mt8 600x300 cooler with 3" piping 3" exhaust standard turbo manifold with 38mm external gate with 10psi spring and screamer pipe forward facing plenum with xf throttle body 750cc injectors on top feed rail with adjustable fuel regulator 3mm head gasket standard garrett t3 turbo and would this be safe or should i run smaller injectors?

Thats alot off injector for that setup but can be tuned and prob 150 ,170 kw with that small turbo put a bigger one on and use your setup!!!!!

bigger turbo what ya think

Yea mate use a gt3540 and if you want a cheaper turbo that works get one off proboost tune it up on 16psi or more it will be a killer street car as long as you have got a good gearbox to hold it and put a 044 fuel pump in to i made 308kw with same sort off setup awhile ago but i had to4z on 20psi but i had good auto
