R33 GTR 6spd getrag conversion

[Tomak]

Hello,

 

What parts do i need to buy for r33 gtr getrag 6spd conversion?

2 x r34 prompt shaft for rear and front + r34 rear differential? 

I am looking to buy whole r34 set engine + getrag but also consider buying seperately. 

What ratio has a front r33 and r32  differential and does it matters with this 6spd convertion? Do i need to have also front differential from r34 gtr?

What in the situation when i use front and rear differential from r33 with r34 6spd getrag. is it going to work this way or not?

R34 diff ratio is 3.545

R33 diff ratio is 4.11

You don't need to change diff ratios with the getrag conversion, use your current R33 GTR sump OR use the R34 sump with the 3.545 ratio and make the rear to suit. Up to you.

Box, front shaft, rear shaft, clutch

Just note fitting one in a 32 is a bastard, I'd assume the same with the 33. 

The pull type clutch with damper is a good amount thicker meaning clearing the nose of the box is hard work. Some people clearance tunnel as a result. 

Converting to push type seems to make this a bit part a bit easier. 

 

You will need to make up some transmission mount spacers as the mounts on the body are different too.

this plus r34 slave, r34 gearbox mount and cross member, use the r33 speedo sensor, getrag gear stick, change the plugs on the wiring so that your neutral switch and reverse light switch plug in

all for a 20 year old gearbox that's hard to get parts for.
