My '91 turbo has significant weight reduction thanks to having caught fire last year. Prior to that it had a ported turbo, 3 inch exhaust and some other stuff. Pretty quick for being untuned. Always ran about 15psi. I started rebuilding it but have lost interest recently.
My '86 NA is pretty basic. Suspension, wheels, bolt ons. I've had it a few years. I race it from time to time. Its not quick but its small and nimble which lets me dance around the cones.
