On my 89 ta i have 3.55 gears, power pulleys, full 3" custom exhaust with dual tips and hooker hedders, k&n filter, and msd 9 mm wires. What modifications should i do to push my horses even further? Should i do something to the tbi (free flow), .5 spacer. List mods other than heads and cam for now please. Need the power and any suggestions would help.

what kind of intake...Edelbrock performer???

 

You said that you had a K&N filter, is it an open element or just the stock replacement? If it's open element that's good, if not, just suck up the loss and get an open element. Go read the Ultimate TBI article in the Tech Section and do that stuff. Take Tas's advice on top of that and you'll be alot quicker.

if you got the bucks to do an intake i recomend the performer tbi. it will serve you very well.

the ultimate tbi is basically a bored out tbi, correct? If i didnt have the tools and the time i could just purchase one of the bored out tbi's from turbocity? Right???

 

no the ultimate TBI just radiuses the top lip of the throttle bores.
