Basic upgrades.... but good power gain... Posted by Jon [Email] ![]() ![]() ![]() In Reply to: Engine Mods, John Giebenhain, Mon, 26 Nov 2001 13:10:24 Members do not see ads below this line. - Help Keep This Site Online - Signup |
You have a few options (many actually)
I suggest an apc upgrade upgrade (spg9 stage 1 apc is what i have on my spg), a 3 bar fpr, and a k&n intake. If you don't want to spend the money on an apc upgrade, there is a mod you can do that will make your car boost higher for about 3 dollars. Search the board for the apc solenoid using a windshield washer check valve. I forget the title of the post but somewhere there is a link to a site showing how to do it. I added this to my setup (i had a spg9 stage 1 apc, 2.8 bar fpr, K&N intake, and a 2.5 inch group six cat-back system) and now am pegging my boost guage on my '90 spg, next step is getting a clutch that won't slip in 3rd 4th or 5th with all the power (you won't get the insane boost i have unless you do everything i have, the solenoid mod, and others alone won't make you peg your guage or need a new clutch, you'll probably gain 20 or so hp maybe 30, but thats a rough estimate)
