@GTSBoy @Kinkstaah Thanks very much for the replies!! So the car has been tuned @ 480kw on a dynapack dyno. ABS has already been removed from the car, so there won't be an issue there. So far, I've had no problem with the rear axles. However, I primarily want to upgrade the diff for drifting reasons. Upgrading axles was rather something I was considering due to power reasons as well as if it was worth changing the whole rear setup while doing the diff... I'm thinking of going with what @robbo_rb180 said: a 1.5 way GT pro diff with some new axles? What do you guys think? what axles would you recommend Otherwise, there's a s15 diff for sale near me for a great price .. would save me a lot of money.. do you think this would do me good for the power the car makes? thanks - sorry for being a bit of a noob.

I would like to mention I've done research on this topic. However, I have struggled to find an answer and am here seeking advice. I have an R34 Skyline GT-X (series 1), meaning a stock non-turbo automatic. 2 2-wheel drive IRS (no HICAS), and no viscous lsd option. It has an open diff, from my understanding it is a R200 ABS Open Diff 4.08 ratio 3x2 bolt pattern. I have stock GT axles. The car now has been manual converted and running a forged 25det making around 600hp. The open diff is a nightmare. I want to upgrade the rear diff for sure. I am potentially interested in upgrading the axles as well as I know some of the other diffs can be put into my car if the axles are changed - also not really sure how they hold up with the power my car makes. What is recommended? I saw for sale a "R33 SKYLINE RB25DET 4.0 3x2 BOLT AXLE R200 LSD DIFF HEAD" for 750 NZD - is this a potentially good option? Would this be straight bolt on? Thanks

@robbo_rb180 @Butters @Duncan Thanks for the help guys. If I were to purchase anything I would purchase this one: https://franklinperformance.nz/products/ls-alternator-upgrade-kit-for-nissan-rb?variant=37295972253850 What do you guys think?

Hi all. I've been looking into builds and information online and have found a considerable amount of people upgrade their rb25det alternators to the LS alternator which outputs more power. I had some trouble previously with could have been an alternator but I have a spare now my engine is out. My engine should be going in soon. I will be running a haltech 2500, haltech dash and planning to get installed a headunit with apple play (i.e a screen of some sorts) and potential LED's etc. Do you think while my engine is out, I should upgrade the alternator? Please note, I do not have much mechanical knowledge, so apologies in advance if this is a silly question.

why wouldn't it be fun to drive? This same car used to make 300kw and I was looking for an upgrade. I will be running it on low boost most of the time anyways thinking somewhere like 350kw. Out of curiosity what other upgrades would you recommend doing/getting for reliability and power? what is restricting the build at the moment the turbo?

It's a street car, manual. Won't be driven on the track much (if at all). I agree that removing VCT isn't ideal but this was done by the previous owner. What would the other option be? Do you think it would be better to get different cams and reinstall VCT? Other than turbo coming on later and lower torque will the overall power of the build be affected much? and are these going to be noticeable later turbo etc?

Read my reply below.

aiming for 450kw to the rear wheels.. and that's the issue the cams don't have the engraving on them but they look big. what do you think the effect of having no VCT and going bigger cams will have? VCT is normally something you would not want to remove

I had purchased (for a good price) a 25det neo engine forged from a family member of a friend who sadly passed away. CP o/s Pistons, eagle rods, arp everything, kelford cams, springs and gears, polished inlet and outlet ports, nitto head drain, N1 oil pump with billet gears, crank collar, gates racing belt, NZ wiring trigger kit, sinco manifold, PSR 5855 dual ball bearing turbo, front facing plenum and rail, 90mm throttle body, turbo smart wastegate 50mm, r35 coil conversion, 535lph fuel pump, 100mm intercooler, haltech 2500 elite (and more that I would need to check up on but you get the idea) The engine forge itself was not done by me, however, all the other parts (wastegate, coils turbo, etc) are parts I've purchased. The issue I have is that the VCT has been removed by the looks to run bigger cams? I haven't seen this done before and struggling to find online why he would have done this... If anyone has more knowledge on why this would be done and how it affects the overall build that would be great. I'm hoping for 450kw what do you guys think about the parts I've chosen to achieve this?
