Anyone have any experience with modifying/tuning an 8valve NA motor for HP gains. In search of some tuning advice. Current mods, 87 900s bottom end, 8v head shaved .075, magnecor wires, blue coil, MSS race header with 02, no cat, cherry bomb (flowmaster copy) and turbo tailpipe, all 2.25 inch.
Fuel enrichment at the fuel dist gives great power at WOT but runs like a pig around town and at idle.
Seeking similar output to a stock 16v turbo or more would be nice.
Talking with Brad at KCSaab about putting together a top end combo. Building a 2.1 based motor combo for the car. Have a pair of 2.1 bottom ends to work with. Generation 1 will be a stock used block with my shaved head plopped on top. The second will have some special stuff done to it. Plan to use the upper end combo from Brad on this incarnation. I need to do something soon as I think my current combo is about to blow up. It had over 200k when I put it together a few years ago, and has been rode hard and put away wet!
