Clifton Posted March 24, 2007 Share Posted March 24, 2007 A stock P90 long block with cast pistons is good for an easy 400 rwhp if you have the turbo, boost and fuel for it. Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted March 24, 2007 Share Posted March 24, 2007 it will also depend what turbo you run. as the stock t3 will start to run outta breath around 15 psi and at that rate you will have around 300 whp w/ that turbo if everything is tuned correctly. I take it you are using stock fuel injectors? You may wanna ditch those and get a pallent fuel rail and some upgraded injectors... size depending on how much power you want to make.

cygnusx1 Posted March 24, 2007 Share Posted March 24, 2007 There is a sh!tload of information about this in the turbo section. This path is the one most travelled. I think there is even a breakdown of HP vs $$ vs Mods ranging from stock to outrageous L28ET setups. Quote Link to comment Share on other sites More sharing options...
