5.0 mods

overez · 02-09-2005, 04:26 PM

I purchased a '90 GT recently. The car is exceptionally clean except for some faded paint on the hood. The driveline is bone stock w/AOD and won't get out of it's own way...it's a little down on power. I was thinking about a head & intake swap, but not sure if this would require larger injectors. I would like to keep it all Ford, GT-40 heads and Cobra intake, 65mm TB, 70mm MAF from FRPP...
would the 19#'s support this or do I need 24's?, if so, do I need to do anything with the ECU? ...any suggestions?

i dont know a damn thing about FI but i can tell ya this...if u want ur AOD to go ANYWHERE put a converter, gear and shiftkit in it before anything else.

Install an adjustable fuel pressure regulator so that you may increase fuel pressure accordingly. I beleive this will hold you. 24lb injectors would be a great idea, but are not neccessary. As for the computer, nothing NEEDS to be done. Just make sure to purchase a MAF calibrated for 24lbs if you do go with larger injectors.

thanks for the advice...
I sold my GMC Syclone last year...this car is a lot easier to wrench on, cheaper too.
