Have not decided what turbocharger I am going to run with.
I run with T3, and want to pull 6-700hp at the engine...
Any suggestions?

Depends on what fuel you're planning on...

E85 "Ethanol"

E85 "Ethanol"

Any of these would get you there with ease:
Forced Performance HTA3582r, HTA3586r, PTE6262, GTX3582r, Super40, Comp6262, ect.

You can get better spool with a smaller 58mm wheel but would most likely need to run above 2.4bar, need cams and porting.

Thanks alot! I´ve been looking at PTE6262 and GTX3582r and they seems to be solving my HP...

Hehe, thanks!

Been in the garage this weekend

Oilcooler in place


Cut my intake to fix some fitment


The fuelrailen will be "build in", and will give the fuelinjectors a better angle


Fixing some vent for the 7A-valve cover. Will place a 90degree connection in the back of the cover so it will be hidden. Then a hose to my oil catchtank.






Mounted the front bumper last night.

Hope this will due for ventilation of the valve cover.

Drilled a hole and welded a bit by the hole.




Also welded a tiny bit of cover on the inside.




Will put a 90 degree tube connector on the side against the firewall pointing at the gearbox.
