R34 Gt Vs Gt-T

[LukesR34]

Hey guys,

I own a R34 GT-T and only recently realised during a clutch upgrade that it was originally a non turbo GT. Previous owner just replaced the GT engine for an rb25det neo but left the GT running gear in (gear box and diff)

Can anyone tell me the difference between the diffs and gear boxes of both models as my car made 200Kw last dyno run and i'm a bit worried I may be pushing the GT gear a bit to hard.

Also any opinions on upgrades would be appreciated

Cheers,

Luke

The RB25DE gearbag is the same as the RB20DET (ratios slightly different). ie, not really strong enough to handle the torque of an RB25DET (unless the RB25 is left fairly stock). The 25 turbo box is almost twice as big as the RB20 turbo box.

The diff is as strong as a turbo one. The only problem will be if it is not LSD, you will spin up one rear, which will slow you down, use tyre rubber and eventually break the diff if you twat about in it too much.
