The new R32 super close box is installed Took me two and a half days due to installer error It's the first gearbox rebuild I have ever attempted, with plenty of advice from some very helpful guys on here and a hand from my brother it all works fantastically! Shifts are waaaaaay shorter than the 260z box and oh so nice, acceleration through the first three gears is much different, at 6,000rpm in first I'm doing 70kph and there's still 1,200rpm to redline. In second and third the power really sends you back in the seat. Ha!
The problems 1)Shifter. 2) Reverse switch. 3) Clutch assembly. 4) Box crossmember/Vibration
1) The R32 shifter is too fat and hits the console. I cut it down leaving the 10mm thick section only, basically removing the bonded upper section. This is usable but not with OEM L series shift boots as they will stop you from picking 1st, 3rd, 5th. I will modify it to match my 260z offset shifter and be able to use the oEM shift boots.
2) I fitted two different reverse switches that were 'making' in different positions (e.g. in or out) and both times the reverse light were on constantly until I picked reverse :-\ I did put three bond on the terminals to stop them seeping oil, perhaps it has some conductive properties? No biggie, I can fix that very easily.
3) The main time cost was the clutch bearing throwout/carrier, during assembly I must have knocked it and one side of the spring had popped off. The result was no clutch, no gears, the only give away was the clutch fork was sitting on a slight angle. So out it all came again, second time was fine.
4) Also, I had to customise the centre section box crossmember to get the 30mm extra length required. I did notice a vibration at about 105kph and it increased at 110kph, I'm guessing it's due to miss alignment of the prop shaft??? Maybe I got the height slightly wrong, Kameari do an off the shelf mount made for S30's with the 71C box so I may go down this path. It'll still use the OEM box mount.
Any input appreciated...
