Hey guys, just needed some advice for my r32gtst.

Ive recently got some r34 gtr brembos for the front and know that the front needs to be drilled out. i wanted to also do something on the rear as i was upgrading a fair bit for the front and i came accross the hfm 337mm rear rotor upgrade kit https://holfordmotors.com/store/HFM-3376418. Just wanted to know if this was a good combo for the car and if i needed to change the master cylinder or booster at all?

My car currently has r33 gtst front brakes with trw lucas pads all round, high temp fluid and it does feel good, but im looking at doing afew track days soon.

Thanks

You don't need to drill anything. Put helicoils in the caliper, much easier and not destructive. Note the bolts will be different (1.5mm pitch on the Brembo calipers, 1.25mm pitch on the Sumitomo calipers).

the R33 brakes should be fine though, the GTS-t is lighter than the GT-R. You'll probably get better performance from higher temp pads and ducting. The Brembos do look better though.

Can't comment on the combo, but I think the bias will be off slightly (bigger calipers up front). In saying that, it should work fine (I did a track day with 34 front Brembo and standard 32 rears).

My master is crapped out and I have a spongy pedal. I have a BM57 ready to go in when I'm not lazy, so I can't really answer your question (different scenario for me).

But, I have read that people have put the Brembo on the front and said the pedal was fine.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      R32 GTS (RB20DE) Injectors Replacement

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
