I'm anxious to see the dyno results, 12psi on 9.4:1 is a nice amount of boost, you must have an efficient intercooling setup. What octane fuel are you running?

i got the big NPR intercooler which is about the same size as the intercooler. i got 2 1/2 inch piping going from the turbo into the intercooler and 3' piping going from out of the intercooler into the throttle body. I run 10psi daily with nothin lower then 92 octane and ill turn it up to 12psi and run 100 octane.

good point.... https://www.nopistons.com/forums/pub..._DIR#>/dry.png



im guessing you meant as big as the radiator? cause those npr's are huge, hopefully mine is still being held onto while i scoop up the cash (i wish i never got arrested again, life sux)



kevin.

is that a S4 or S5?

yea i meant as big as the radiator.. sorry my last post was really screwed up. i was gonna go with the littler NPR intercooler and mount it horizontally like the link thats posted a little earlier.. but i like the big one.. and it fits perfect right in front of the radiator.. like its meant for the FC. but i got a 87 gxl non turbo.. i had to port match my turbo II intake manifold to fit my six port motor cause i used a third gen exhaust manifold and it wouldnt clear the 5th and 6th port pumps. anyone got another 6 port motor that needs rebuild that they want to get rid of?? im trying to build me another one.. thanks a lot
