Engine head.
Which one would you recommend in terms of performance and reliability on a twin turbo Z33? I have an intrest on the Nismo heads or Cosworth heads which one would you prefer?

cams have nothing to do with compression
NISMO heads are not for use on a FI car.
For a bolt on solution, the Cosworth heads are a great option. Or, you can buy a spare set of heads and have a local machine shop to you port, polish and work it that way (might end up being more cost effective).

not 100% sure if the heads from the Maxima would work...I'd suspect they would but I'd do research if I were you
If you are after a set of Z heads, let us know...we have a set for sale that is complete, perfect for someone building heads

Can you send me a PM on prices. My car is finally about to get out of the shop with all bodywork/paint/wheels/tires so now I'm starting to look at more supporting mods for FI. -I want to drive my car for a little while (haven't driven it really in about a year) then when winter hits get the interior and FI done.

Static compression ratio is pretty meaningless except at cranking. Because rarely does anything close to atmospheric pressure ever get into cylinder except near the torque peak rpm.
As the dynamic [running] compression is controlled by the VE which is a function of cam shaft duration and lift.
Study BMEP, FMEP
