Hi again. My diff is, in technical terms, buggered. I was wondering if I could make a Frankenstein diff out of a diff like one of the silvia or 300zx diffs (not sure which one) as I would like a bit more taller ratios as I drive on Wellington highway everyday. Is this a possibility ? Or do I have to just buy a R33 diff ? They are 350 on trade me at the moment. Any other options I haven't thought about? Any advice is good. Thanks in advance RB gurus lol

Thanks for your answer bro can I used the speed sensor from the rb25det or do I have to modify the rb20 one ? also can I just use the front half of the NA drive shaft or do I have to cut the existing one and connect the two ? Sorry new to drivetrain stuff ! Shop said 2k for rebuild on big box WTF!!!

Hi all I have a r33 coupe rb25det, it has a big turbo box in it but it crunches and whines now. I have a spare rb20det gearbox and would like to put it in. And yes I KNOW it not the best option and all that but I just want to put it in to tie me over while I get my good one rebuilt what is required for the swap? Is it straight swap? Seen a lot of r33s with small boxes in them but can’t find any solid info on how to do it. cheers guys !

Anyone know anyone who done this

What about the 5 speed RWD box ??

Hi everyone I've seen/ heard a few things about the Nissan Navara Gearbox being the same or similar to the RB25DET and rb30et gearbox. Is this true and is it worth the effort trying to bolt one up ?!?! Sounds like a cool trick haha found a 2wd 6spd manual for 1k on trademe... Anyone know any solid info about this ? Cheers

I figured out why my car was "misfiring"... my r33 gtst was playing up when any throttle or boost was applied, misfiring". So I hooked up my laptop to my link g4 ECU and ran a data log and found out on that log I had been boosting over 26psi !!!! it was tuned on 15psi and made 320hp to the wheels and one day started doing this weird fuel cut or ignition cut thing. SURELY this has something to do with it, but I cant find any fault codes or anything been thrown up when im hooked up to the ECU. The only thing is a couple time a RPM limit popped up but i was no where near the 7500 redline. ???? I have no clue with this tuning stuff so any ideas ?? I also blocked off my boost controller to the wastegate and still did the same thing as before but didnt run a data log to see what was up. I will attach the data log to this. (9:51 mins is where I boost spike the most) Thanks for all your help. Log 2019-06-1 2;08;29 pm.llg

Thanks everyone

Hi I have a R33 gtst s2. My check engine light blinks 4 long blinks followed by 6 fast ones. I looked online for a code that would be 46 but couldn't find anything. The closest is 45 and is injector leak and 47 which is CAS or something... It also misfires SO BAD that you can't even use quarter throttle. These blinks are on start up, while running it stays on. Any ideas what this could be ?? The car also has a link g4, 440cc Injectors and big turbo with 240kw tune. Any help will be much appreciated thanks !!

Cheers for the help everyone... Now it won't even IDLE properly?!?! Does anybody have a clue what going on.

Split fires are so expensive wow

Must be time for some newies. Any suggestions

Cheers mate, if not coil packs and sparks what is your next guess ? I'm new to rb's lol so thanks heaps

Red mate !

(won't stop all the way through rev range)

I recently bought an R33 gtst with series 2 RB25DET. I turned the boost down on my manual boost controller when I gave it an oil change now whenever It hits boost or even half throttle it will misfire and WON'T STOP at all... Check engine came on after oil change Has link g4 440 injectors bigger turbo 42mm wastgate and straight pipe... Tuned to 240kw on 15 psi Changing coil packs and sparks this week.. any help appreciated thanks

Cheers guys ! Looking into forged kits now ?

hi everyone I want to know if a VQ30DET would fit into my 2004 350gt coupe ??? I want to either do the 30det swap or boost the stock engine but thats a whole nother conversation... Maybe a vk/vh45de swap??? In other words I'm bored of the vq35de and keen on some BOOST or some v8ness lol the old girls powers not cutting the mustard now... Please let me know yours thoughts cheers everyone !

I am building a rb30det with t3/t4 ar.50 turbo, Z32 AFM, 440cc gtr injectors ect. All fitting into my r32 coupe with rb20det wiring and ecu. I am wanting to nistune this ECU to run my new set up ! Is there anyone that knows how to do this easily and can tell me how to do so? Ive seen on a video that you can just imput your afm and injectors ect. Is this true ? Any help welcome ! Cheers guys
