Can a na rear diff fit on a tt subframe with some modifcation to the subframe i take it the na has diffrent mounting holes.R200 na diff/R230 tt diff .Also do all na models have hicas thanks taff.

Too much work. Different lenght and diameter drive shafts, mounting in totally different place, hole for rear of TT diff to peek through sub frame too big for NA diff + completely different prop unions. You'd be better to get the whole NA sub frame, diff, prop and drive shafts.

 

Remember though, unless you strenghten the shafts and the diff. 400bhp is the max they'll take. NA's don't have HICAS and the whole assembley is much lighter.

Thanks mate also do you know if there is a diffrence between a swb and lwb tt subframe and do swb cars have a shorter prop .Also the R200 diff fitted to the na model is the same as the 200 sx and skylines 200 means a 200mm crown wheel these are very strong and over enginered and ive seen them on 500-600 HP S13 .Norris designs s13 550 bhp car ran a standard R200 Diff with hundreds of full throttle launches on drag tyres.And a lot of big power skylines still use the r200.thanks taff

SWB and LWB are just the same sub frame for NA just shorter props. The Same goes for the SWB & LWB TT.

As regard the NA diff being the same as the diff on the Skyline and 200sx I couldn't tell you. I stick to passing on what I know and especially what I've tryed and tested.

Just a thought. If you have access to part numbers you can check out the drive shaft No's and the Diff No's. Also remember the Skyline GTR's are 4x4 which means that not all the power is pushed through the rear drive and so it is quite feasable that they are the same.
