swap the pulley to a 2.3 or 2.2 but scan scan scan for Knock retard!

Stock chargers are designed to push ~7.5psi.

There sure are things that can be done. Before you change up stuff though.. you will want to check fuel pressure, and pick up a scanner to keep watching for KR (Knock Retard). This is to maximize the power and effectiveness w/o causing problems or having the computer pull power via timing because of a lean condition or predetonation.

1. Buy a fuel pressure gauge and check it. If it'* out of spec, replace the pump and/or FPR.

2. Remove your exhaust manifolds and inspect for cracks. You have them. We all do/did. I strongly suggest porting them at the same time.

3. BUY a scantool. You'll need to scan now for KR and periodically through the hotter months.

4. NEVER run anything but 91 octane or higher. Consider a higher octane with the smaller pulley if it'* available.

Failure to abide by these guidliness can spell doom and BOOM for you. And it has in the past for a couple people. These cars are getting older, and these things need to be repaired BEFORE doing any pulley changing. SC pulleys are not a magic mod on any L67. Supporting mods must be done first.

Stock, a 92-93 can reach 9-10 pounds.

In most cases. I think the average (IMO) is actually somewhere around 8 or 9.
