I'd have no problem spending $2K on a transmission if It would be bulletproof. Problem is, a "full out" built one such as yours runs a cool $8000. I'm a pilot, I don't have that kind of cash sitting around burning a hole in my wallet I'm afraid. And if I did there a million and one other things I'd rather spend it on than a transmission.
I'm just about done with this car. The platform is dying, and I refuse to keep dumping money into it. I've spent probably $50K to date, and I'm still not happy with the fucken thing. You've spent much more than that on yours I'm sure, was it worth it? As for "OEM garbage that might or might not survive" what's saying the PAR setup will survive either? People have broken them too. All it takes is a hairline crack or manufacturing defect, and its game over OEM or not.
This isn't a 1300HP drag Toyota Supra. It's a 2600lb grocery getter that I blast to the mountains and back with on sunny days. I think I put 6,000Km on it in the last 5 years. Point is, I need to make this car "fun" again. Not just to drive, but to work on, too. If I can put together a transmission for $2K that will hold what I need it to and a little more, I'll be happy with that. Sure, custom ratios and double cone synchros are awesome, but at the end of the day, it's still just a car.
