What Do I Do First Reply #1 – December 14, 2007, 08:36:22 AM Open up the exhaust and intake first. Engine bolt on are only as good as the car can breath. Quote Selected

What Do I Do First Reply #3 – December 14, 2007, 10:01:06 AM The first thing you should do is a good tune up and a new fuel filter. These things can get finicky under boost, and any minor issues with the ignition or fuel system will only get amplified. Use Autolite, MotorCraft or NGK plugs. No iridium or platinums. Use Motorcraft plug wires (they are cheap, easily available and are known for less "issues")As far as performance goes, the exhaust should be the very first thing. It's amazing the difference a 3" downpipe and 3" single (or 2-1/2" dual if you just HAVE to have duals) will do for these.A manual boost controller will be good after that to up the boost a touch, but the IHI turbo on the car now is really only "good" up to about 18# boost, after that you're just heating the air w/o much gain. Swapping to the Garrett T3 turbo found on the rest of the turbofords will be a minor "upgrade", but would be a cheap way to up the power.BOVs sound "cool", but on a stock system they are really not "needed" and can cause minor issues with the air metering as they vent metered air during shifts and can cause a temp rich condition. For a stock setup stick with a BPV (ByPass valve) that recirculates the vented air back into the system. While not as "cool", they are far more practical. Quote Selected

What Do I Do First Reply #7 – December 14, 2007, 09:04:45 PM After a tune-up I would do 3-inch Exhaust, K&N Mounted on VAM, Gillis Boost Controller (18#) and have a Walbro on stand-by. The Forge BPVs (or at least the one I had) aren't all that quiet. Quote Selected
