excelent. this compliments my topic on master cylinders.

ive got some ktype alcons on the front

and ap 4 pots on the rear.

origonaly i had f40s. (38mm/44mm) same as porche big reds. 340mm rotor

on 355 and 330 respectivly. now they work realllllly well i can go flat out thrue the kink a wakie no problems. (about 220k) and it pulles up strait and fast.

now i recently changed to the alcons. (piecing together my f40 kit so i can sell it) these run larger pistons. (more leverage) they woprk great buy now i find the fronts are working to hard and there isnt enough going to the rears. (FRONTS BRIGHT ORANGE AND REARS NOT EVAN RED)

my point here is that the 1 inch master on a 32r is great. if only it didnt have the proportioning valve in it. an external one would be the shissel. does a 300xz one have it built in? and its bigger. 27.88 or somehting.

i was looking thru the prb book and theres alot of nissans running 25.4 (1 inch) masters. i just need to find a ilistrated book. or go to the wreckers and rumage thru the box. lol.

seems a few peeps seem to think that the factory pressures are wrong. but its the valve thats the issue. and f**k putting a pedal box with a balance bar in lol.

(and on the v8 supercar. welll sorted,, 5/8 ap cylinders pull type) sbr001 ba coon) the balance bar is alllllll the way over one side to ge the reqired 800ps1/600psi split. prettu usless i rekon.

or and that brembo lables ment to be white. now its dark blown lol the alcons came with knockback springs on the trailing piston. (large one) slight squeek but that it :)

If it's front bias, then you have the "endurance race" rear master cylinder in it to allow for the fuel load. Change to the "sprint race" rear master cylinder and you won't have that problem.

:stupid: cheers :happy:

you get floating hats?

I think my calipers have knock back springs, as i can always hear the pad's rubbing. I still get bad knock off, i'm hoping a bigger master cylinder will make it a bit better.

yeah. i cleaned the hub properly. ie no rust at all!!!!!! and had them machined. i think it must be wheel bearings cos its only on cornering.

is it definalely front causing the knock back? i have had the GTR and my old R32 do the same thing in the hills on me and it turned out to be rear hub bearings knocking the rear pads back in the caliper.... and it only happened initially when giving it stick in the hills or on the track.

Has anyone heard any reviews on the Project Mu calipers? For an S15 they have 4 pots on 345 x 32mm rotors. The pack with brake lines, adapters and brake pads was $3700 local. Probably cheaper overseas.

I'm in the market for a brake upgrade...

As usual, the tyres are the limiting factor. Past experience has taught me that a set of properly maintained standard R32GTR brakes with decent pads and fluid will outstop any road tyre.

That i can vouch for; The std brakes on my old 260rwkW R32 GT-R never got anywhere near to giving up at either The Creek, Oran or Wakefield, whereas the Falken *cough* Ziex's *cough* had well and truly had enough after about, oh, a lap and a half.

save on brakes- buy shite tyres. lol

(sorry for thread mining :))

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
