Are the flanges of gtr and non gtr r200 lsds interchangeable? Im getting 1 piece driveshaft made up and want to run a gtr diff eventually so I can run stronger half shafts. At the moment I have a good condition 2way but am converting to gtr transmission, already have a gtr driveshaft and gtr diff input flange, can I just install the flange on my 2way and switch to gtr diff when I buy one? How do you set up pinion preload on them? Not sure if it matters but car is an R32 4 door running an R32 sub frame.

Thanks so much for the replies guys, just the sort of info I have been looking for. Out of interest, is there any sort of advantage running the z32 afm when the link g4 allows the tuner to just run off map sensor? Im guessing I would possibly be able to stay with nistune running the z32 afm?

I have been running a 25det neo in my r32 for a few years running the following set up: Walbro in tank fuel pump Electronic boost controller 3" exhaust Front mounted intercooler Pod Filter Tuned with nistune on BP 98 fuel it made 300 hp 295 ft/lb Having done 12 or so drift days I am wanting to up the power but i want to focus on mid range power / torque specifically , wanting to make a nice torque curve, not focused on a peak kw/hp number but want excellent throttle response. I have already upgraded the drive line as the rb20det box is finally starting to rumble since i rebuilt it 2 years ago when i did the engine swap. I am wanting to do bolt on modifications to bump the mid range, i don't want a really narrow power band that kicks in late in the rpm. There will be plenty of people out there that say build a rb30det but the neo block is still mint condition, makes no blow by so i would rather have a crack and just doing a few bolt on mods and seeing what i can achieve. Plans so far are Link g4 computer (can remove a.f.m) Leave the intake manifold stock and run a blitz style V-mounted intercooler with the intake and outlet on the same side After market injectors (not sure on what brand or size yet, just know i dont want hi-flowed injetors) Fuel cell and surge tank set up, not sure on what fuel pumps to run yet, i want to run E85 though so will need to change all the rubber hoses Turbo, not sure what to run yet, i want to go with an internal waste gate type to keep the actuator and it's rubber diaphragm away from the heat. From the dyno thread on here it looks like guys that run modified stock turbos are way down on torque despite being similar kw number to guy running the likes of garret gt30 series turbos. Could it be worth talking to a turbo guru and getting something made specifically for the task. Exhaust manifold, not sure what to do here, stock cast manifold is known to be good for not cracking but is it going to be restrictive? There is a local shop here that guarantees his stainless manifolds against cracking and that the will make more power than off the shelf manifolds. Cams and adjustable cam gears, Pon cams are damn cheap, are they going to benefit my mid range goals or would something custom or standard be better? Head gasket, would it pay to upgrade to a steel headgasket? Would it help response bumping the compression up a little by running a thinner gasket? Thoughts and suggestions? Am I over engineering it? I'd prefer to plan it all out first than rock up to the tuner running a generic china turbo, exhaust manifold, front facing plenum and come away with 300kw but a dyno plot looking like Mt Ngauruhoe Thanks in advance!
