I put the head from fiat stilo 2.4 20v for my 20VT.
I heard from one person that it will delay the turbo spool and does not give extra power.

I wanted to use the head of the Fiat Stilo 2.4 and do the valves on the 3 angles.

As it is with the head of the supercharged engine?

I currently have:
- Turbo garrett GT2871r a/r0.64,
- Exhaust and dp 3 "
- FMIC
- 440CC bosch injectors and Walbro 255

I have done 2 Maps 1.6 bar and 1.9 bar.
