Hey guys,
So digging this back up after a break...I'm now looking to do the swap in early October and I have a few questions I'm hoping I can get some pointers on. As a reminder, I'm looking to swap the auto transmission in my 1990 2+2 JDM Fairlady 300ZX to a 5spd. I have managed to acquire about 70% of the parts and now just getting the rest before the swap.
I have got hold of a NA transmission and driveshaft. Will these work within my TT? I have been told before that the NA and TT gearboxes are pretty much the same (albeit with some dimensional differences which I'm looking to work around by spacer plates and boring out the inside using grinders etc.). I'm more interested that the transmission in the NA is capable of taking up to say 350 BHP from the TT. Also, and perhaps more importantly, I have a NA driveshaft. However, if I am packing out my transmission to fit the TT body/flywheel, will this affect the length of the driveshaft I need to install? Basically...will the NA driveshaft fit my TT with a packed out NA transmission?
Can the swap be done without pulling the engine? I have read that the clutch hydraulic lines are difficult to install correctly with the engine in as they run out of the master cylinder behind the engine. Anyone done the swap without having to lift the engine? i don't really have the capacity to do an engine pull so looking to avoid if at all possible.
Also, the transmission oil cooler line - I have heard that this has to be fabricated for the Fairlady JDM to UK swap. Anyone know of anyone I can speak to about getting one made? Or whether it's actually required? I have heard folk say it's not really needed. Anyone able to shed any light on this at all?
Lastly, if anyone has any pointers going into this, and any little tricks they learnt or people I can speak to for help and advice it would be massively appreciated. Especially tools required...
Great community on this site, and thanks again for taking the time to read :)
All the best!
Phil.
