RBish

yes r32 gts-4 came from factory with rb20det awd & 5 stud. so standard r32 gtr rotors should fit as thy run the gtr caliper?? i was thinking i may need a cert as i have stepped up 0.5 litre in capacity.

Hey i have just done a AWD NEO RB25Det conversion on my R32 GTS-4. i have 2 questions. does anyone know the biggest rotors i can get to fit? as i dont want the pits to send me back after fitting stock size r32 gts4 rotors. it looks as tho the gts-4 runs the gtr calipers but smaller rotors. stock 32 gts-4 rotors - Front 290x30 Rear 292x18 stock 32gtr rotors - Front 296x32 Rear 297x18 and what have your experiences been with registering an engine upgrade and then did you need to also upgrade the brakes in size? i know laws change from state to state but info would be helpful. thanks.

thanks for the info, heaps of room in the guards i just need to clear the caliper, without stupid amount if poke. i think a slip on would give me enough clearance but i dont want to run slip ons so perhaps a 10 or 15mm bolt on would do it, if i can find a set that is. i would like to run a stretched tyre but nothing too crazy either what sort of mods do you need to do to get the 25/30 working?

now things get interesting with the 3 litre. i have a set of enkei rpf1s 17x 9 + 35 offset, what size spacer would i need aprox? cheers. i dont know much about wheel fitment...

good job, cars looking good.

so dope glad to see you put a filter on, is it rwd?

i have rpf1's 17x9 +35 offset and my rims foul the calipers, how did you get these to fit?

sad to hear, looks like a re used tensioner?

got some work done this weekend. i removed sump and fitted the gts4 front diff centre, new rear main seal and resealed sump.

gts4 diff centre and pinion are now in the rb25 diff. backlash is the same as before it was disassembled. i am a happy man

love this thread. cant wait till im qualified , im definatey going to build a race car. so sick of canarys and permits and cops.

removed the pinion nut today with my 1/2" rattle gun at work, the workshop air compressor really helps... and knocked the pinion loose with a copper hammer. now i can get on with this build, thanks.

its not peened either

i had vice grips on it and tried a screw driver to jam it up. probably my weak ass bluepoint rattle gun. will take it into work or into a jdm workshop to undo it and rebuild the diff back up

i am doing a 32 gts4 rb25neo conversion and have to swap the front diff centres, i have everything gutted form both sumps except the front diff pinions. thes are really tight, i have been trying to jam it up and rattle them off but no luck.. how do you get these pinions free?
