help with next mod
I need help on what would be the next wise choice on making my car a bit quicker. I have an 87 iroc 5.0. So far i have ported an polished the heads and the intake. K&N filters. 1.6 rockers, accell cap rotor and plugs. Im looking at some inexpensive ways to make it quicker. Maybe under150 bucks or so....
I was thinking an afpr?? or a chip??...any sggestions on what would be wise??? Thanks guys.

you have more air getting into the engine... but it still has to go out threw the same crappy factory manifolds and exhaust.... i think its time you invested in some headers and a good exhaust

Good headers and Exhaust would give you a great improvement compared to what you are making now. I would also recomend getting a chiip. A good one that I have had experience and know are good are from TPIchips.com. I also would like to add that I think the Gutted TPI box is an awesome free mod that you can do in the comfort of your own garage.
