ive looked through a few threads , and people have said na manuals will hold out a bit of power , my 3 speed auto is making my car chew fuel on long trips, and my mate has a vl na manual box and conversion stuff available for $600 will this bold up to a turbo motor no problem (bt1) and just to make sure...would it handle 14 psi with cooler zorst ect.. (im only running 11psi atm)

i looked at a car for sale running 15pound on the non turbo manual box and he reckons he had it like that for nearly 10 years. As long as you dont thrash it, she will treat you fine is what he said about the box.

well id thrash it 1st 2nd and 3rd...but not 4th or 5th....should old up though shouldnt it? ...and where it bolts up to the flywheel it should be the same shouldnt it....?

if ur gonna thrash it id be guessing mx7 would be best.

yeh , ive been trying to source one , but atm no luck, so im looking at some temperary options....well if it hold up it wont be temporary

my mate had a n/a box in his vl turbo it ran 13 flat all day. just dont race change

i wouldnt even thrash a MX7 too much.....there is a difference between driving hard and flogging.....it will hold up, just have less surface area on clutch plate so may be more inclined to slip, and the gears may not hold up to the sudden rev increases if u are "thrashing" it
