[DMCForum] Re: 24valve 3.0 PRV

["John Dore" <dmcjohn@xxxxxxxxxxx>]

Hi Martin,
I could get hold of a complete UN1 transmission from an R25. I know 
with the final drive ratio being lower that I would have better 
accelaration, but is the box in all other respects as reliable as the 
DeLorean version? Would it be worth my time swapping my transmission 
to UN1 along with the 24 valve engine?
This should be a really fun car to drive!
Thanks,
John
