I presently have a poverty pack R32 GT-R with the Sumitomo callipers etc. As part of a brake upgrade I wanted to change the master cylinder to make use of the larger bore as seen on the Brembo equipped R32's & the 33's etc. The question I have is what is the easiest way of doing this. Now I would think that a master cylinder from a Brembo equipped GT-R would be a straight bolt up but I suspect that it will be next to impossible to find one.

Question is: does the master cylinder from the R33 GT-R fit the R32 GT-R?

Here is a photo of my 32.

I can't wait to hear the answer to this I have the same question. I have done some research and can tell you the 32 GTR Vspec brake master costs about $360 brand new. The 34 GTR master costs a measly $280. (both prices approx off the top of my head).

The only differences I can see in them is the shap of the fluid resevoir but I'm not sure if they come with our without the resevoir.

I say buy a 34 GTR master, then tell me if it fits. ;):D

Sounds like I should just go and buy a new one. Re-sleaving a second hand one will make it way more expensive.

You don't have a part # by chance?

I just orderied myself some rear calliper, um, ies. So the bank account is back to its usual parlous state. Not sure I am in the position to take one for the team just at the moment.

I will put it on the list with the other 428 bits of crap that I need from Nissan that may or may not fit.

Should do. Don't the CP5555's have a smaller piston area than the BRembos used on the GT-R's?

yep - cp5555s have slightly smaller piston area than the Sumitomos, the Brembo rears have slightly larger piston area than the Sumitomos...

worked out ok... and even bias is ok - not locking rears or anything - even with the 322 rear rotor.

sweet

I hope so. anyway I think I'll try the 34 GTR one. it has the ports in the same place etc so it should be ok. the only problem I can forsee is the fluid level sensor and perhaps fitting the resevoir to it (that's if it doesn't come with one).

i think the Z32 cylinder has a larger bore and is a direct fit...can confirm this with John Pelican at Unique.

i have one in stock for $130 plus freight if anyone is interested

Arn't the z32 bias levels up the creek for a GT-R?

  • 6 months later...
Thread back from the dead - did it ever get resolved if a R33/34 GT-R reservoir fits?

Alternatively is there a local commonly available option that will work (eg Patrol etc)

Closest I found was this. It is from an R34 so they do fit, but it was done in Japan & the bloke concerned obviously couldn't say how much messing around it required.

    • 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.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z
