Ok, i have now reached the dilemma of needing to upgrade the brakes on my r32 GTR

the current front set up is evo 10 350mm rotors with Evo 9 4 pot Brembo calipers.. Using Alpha Omega dog bones to make them fit ;)

Piston sizes are 2x40mm + 2x46mm

now originally i was looking at getting some R34 vspec 2/N1 rear brembos that measure 322mm, with 2 pot caliper, though these have been difficult to come by

so my second option is FG Typhoon brembos that are a 4 pot caliper with 330mm rotors, Brad from profab has dog bones that will make them fit so thats no issue

whats peoples opinions, are the typhoon brakes too big, has anyone given this a go? will they stuff up the bias of the brakes

i want to use the car for the odd track day but it will be mostly street.. and i wanna keep it all brembo btw

cheers

Personally I wouldn't bother upgrading the rears, but if you are dead keen the 33/34 brembo rears have been working fine on my race car for years. Just use more or less aggressive pads if they lock up before the fronts

To really bother upgrading the rear you need to have either removed a lot of weight from the front, or shifted a lot of weight rearwards. Standard weight distribution is about 2/3 front and 1/3 rear when static, and it is even more due to weight shift when you hit the brakes. As a result the rears do 9/10ths of stuff all.

Yes cosmetically I only wanted brembos for the rear, but if its deemed un necessary then I will leave as is

Duncan I do see your point, I haven't moved anymore weight around so I think you are right in the fact I probably don't really need to upgrade them. I thought there may have been some distinct advantage in having a bigger rear set up but if you guys reckon there's not then I might just leave them and put some upgraded pads on them

Cheers for the replys

Dont get too worried about back brakes. As long as your bias is good they will be ok. See photo for comparison. Note that with DS2500 pads my rear rotors are wearing out simply because the pads are hard on the rotors when they are cold.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
