Performance Boost

[BuickPower3800]

I have a 1992 Buick Park Avenue with the N/A 3800. Does anyone have any ideas on how I can increase the performance of the car. I have already done the following: 17in. custom wheels, cross-drilled rotors, chip, and cat-back exhaust with high flow cat,180 stat.

Add a cone K&N filter in place of the stock air box, and a lower temp thermostat.

Thanks for the help i just added my 180 stat today.

Find a 94/95 SC, TB and hose. Install it (bolts right on) and swap the 92 pulley on. 20-25HP. Listen for knock.

How would doing that add that much power??

The 92/93 is 57mm inlet/TB. 94/95 is 70mm inlet/TB with Teflon coated rotors. Add the smaller pulley, you do the math. I'm running that combo in my 86 Ciera GT.

Oh, a 2.5" crossover pipe helps too. The stock crossover is pretty small.

But my engine isn't supercharged. Can I still do the mod??

Sorry, I didn't see that it was an NA.

Yeah, but I'm not sure it would help enough for the effort.
