Word of warning, some R32GTR N1's had ABS and some didn't. From what I can tell it was a "delete option", if you didn't want ABS you had to order the car without ABS. If you just ordered an R32GTR N1, it came with ABS. So the "race teams" (they didn't want ABS) ordered their cars without it. Joe public most likely didn't know about the delete option, so they got ABS.

:laugh: cheers :D

Interesting, all the specs I've seen on the Japanese sites say that ABS was omitted from the N1 versions. Will keep it in mind, thanks.

One of the race cars, a genuine R32 GTR N1, had ABS. The other genuine R32GTR N1 didn't. The 3rd car, not a genuine R32GTR N1, had ABS.

Typical "homologation" tricks by Nissan.

:laugh: cheers :D

OK, I managed to track some pics down off of Yahoo Japan of a BNR32 N1 brake master cylinder (BM50) and someone else did a screen grab for me from the Nissan FAST application of brake master cylinders with numbers starting with #46010.

These photos relate to #46010-05U01 for RB26DETT.GT-R.17 N1 (which I think relates to the V-spec N1) which is number 5 on my list below.

The Japanese next to 5 & 6 is as per the following:

(5) tokiko 1 bembutsu(?) confirmed N1 specification

(6) nabuko 1 physical count N1 specification

So a further translation would be

(5) #46010-05U01 | *RB26DETT.GT-R.17 | Tokico 1" N1 Specification

(6) #46010-05U21 | *RB26DETT.GT-R.17 | Nabco 1" N1 Specification

I can only deduce from the 2 versions listed on Nissan FAST to be relating to the first version of the N1 based on a standard GT-R (RB26DTT) running the Sumitomo calipers (#46010-02U00 & #46010-02U20 were 15/16" cylinders), and the 2nd version which was based on the V-spec and V-spec II models (*RB26DETT.GT-R.17) running the Brembo calipers (#46010-05U01 & #46010-05U21 were 1" cylinders).

So after all this, I'll be ordering in either a #46010-05U01 (Tokico) or #46010-05U21 (Nabco) unit depending on which one Nissan tell me to order. They seem to still be available ex-Japan for $445.00 inc GST and $440.00 inc GST respectively (trade pricing) through Nissan. When I receive the unit, I'll post pics and confirm size.

Stay tuned.

OK, unit is received and fitted, didn't want to repeat myself about all the details so here's a link to a post on my blog about the Brake Master Cylinder information:

http://www.sillbeer.com/2007/04/brake-mast...er-upgrade.html

justr to pugt your minds at ease.

with my recent brake master thread. ive fitted a 1980 patrol master. (completly diferant style and about 20mm longer) to mine no dramas.

s15, bolt on

and im curantly using a gu patrol master. 1/1/16 with no proportioning valve(im running a wilwood bias valve)

if its a nissan and rwd and r/h/d it will fit.

common sizes are 7/8,15/16,1,1.1/16. inches.

only isssue is the proportioning valves are all diferant. for example the s14 one reduces by 20% to rear barakes. z32 by 40% so you will find unless you put the s15 valve in the rears wont work as hard and you will cook the fronts.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
