About this Current Vehicle:

I bought this car in 2000 from a Chevy dealer. I got a good price on it, which surprised me since I don't usually buy from car dealers.

I bought the motor from a wrecked 1995 Z28 and a buddy rebuilt it for me, boring it .030 over and adding an Eagle rotating assembly with a forged crank, rods, and 9:1 CR pistons. A four main bolt conversion was done and LT4 heads and intake were used. The cam is a GM Hot cam, the headers are Mac midlength, and the turbo piping and fabrication is all DIY in my garage. The turbo is a 60-1 and is too small for the application. The car has a front mount intercooler and oil cooler and an electronic boost controller.

When the car was dynoed and tuned, it made 498 HP and 579 TQ at the wheels. Power drops off after 4500 RPM due to the small turbo. Boost maxes out around 14 PSI.

The rest of the driveline consists of a Spec stage 3 carbon clutch, an RPM Bulletproof T56, a Lingenfelter 3.5" driveshaft, and a 3.73:1 geared Moser 12 bolt rear axle.

Suspension mods include KYB shocks/struts and WS6 springs and oversize swaybars.

The wheels are 17" ZR1 replicas, 9.5" wide front and 11" wide rear.

Corvette C5 brakes were swapped onto the front, and later model (98+) F-body brakes on the rear, with Hawk pads.

The car goes and stops quickly.

I lost most of my pics of this car from 2003-2006 due to a computer crash.

As with most of my vehicles, there are several bug issues that need to be taken care of that keep me busy.

Turbo swap

I have removed the 60-1 rear mounted turbo and replaced it with a new MP T70. This unit has a larger compressor side and also a larger AR (.96) on the turbine vs the .68 of the 60-1. I did a short road test & was impressed by the power level. I need to have it tuned and dynoed to see how this new setup compares to the old one, which stopped making power at around 4500 RPM.
