Flywheel is in excellent condition, removed from '90 ZR-1 at 23k and resurfaced. These OEM flywheels are getting hard to find and well known to be better than the aftermarket ones.
$450 plus...

Re: Freon capacity for 91 ZR-1?
Bringing up an old thread. So for my '90, it is 2.25 pounds of R12. Does that convert straight across for R-134? I'm wondering since the R-134 is less efficient if it needs more or the same amount?

Re: B&B fusion cat back exhaust
As mentioned above, there is no resonator with this system. The X pipe and mufflers handle the drone. I purchased the full system with cut outs.
