Here's latest pics of the car I built under new ownership. I did get to drive it at SCCA Solo Nationals in Lincoln. What a blast!

Stock motor with headers and exhaust system from Precision Chassis. At under 60 MPH we were under 6500 RPM as we were on tall 18 inch tires. Car just sounds like its spining like crazy. It does have rev limiter disabled but like all stock 2.5's it makes no power over 6000 RPM.

Wow, car looks to perform great in that video! What kind of wheels are those?

I've seen their exhaust system, but haven't seen their headers. Do you have any pictures by chance?

Headers were $99 specials on ebay.

The wheels are CCW classic 3-piece wheels 18x11". Using 285/30/18 front tires and 315/30/18" rear tires. The passenger side header was modified as it had a crimp in it, but don't see much area of improvement in a higher priced unit.

BTW, anyone know where I can buy or have made camshafts for the 2.5 liter motor with limit of 0.500" lift on exhaust and intake? I plan on running the car in E Production road racing and that is the limit.

Grant built a good car, as with just some modification to the wheel and suspension setup, the car set top time on the west course at the SCCA Solo Nationals in FP. It needs a 2.7 liter to fit into the weight parameters better, as it is 140lbs overweight using FP's 0.75x(discplacement in cc) formula, plus 100lb added for wheel size over 10".
