My BL640 GTR

Cool. Zohair told me they were buildign a kit. I assumed it would be on your car. have people figured out how to make the transmissions on the GTR's last yet? I am very interested in turning one into a time attack car. I'm just gun shy with all the trans issues I have seen...

The Switzer P800 cars (arguably some of the fastest GT-R's on the road) have zero transmission work done.

so are all the failures from first gear launches? If I'm not a stoplight racer, do I not have anything to worry about? I have heard for track use they need external coolers for the trans and diffs because of the temps they see. can you confirm?

I've had no problem running 30 minute sessions. Temps can get high up there, but the problem we now see is the stock fluid being suspect (breakdown). Some believe that the stock fluid is adequate, while others are switching to Willall fluids, Dodson, etc..., and notice results with lower temps, quieter gear changes, extended fluid life (not to mention it's cheaper).
The coolers aren't that much (relative cost to transmission fluid issues).

Thanks for all the compliments! As for the responses to the questions asked, jasper, GREAT JOB! I couldn't have answered them any better. The only thing I will add is that I've never seen a tranny failure occur on a car that was not launched aggressively over and over on LC1.
