R33 Alternator

[Mick]

hey my alternator needs replacing in my R33 S2 GTST and i was wondering if there is one with higher amps that i could put in as an upgrade, i want it to be a straight replacement so would a GTR one fit in and does it have more amps

[Mick]

what alternators will work on it, like a 300zx or vl turbo for example, i eould prefer one that has more amps than the stock one if possible

[R.3.2.G.T.R]

gtr ones are 90amp, 32 ones physically larger so try one from 33/34 gtr, should be straight swap-over

[Mick]

i have an r33 gtst, does anyone know if a gtr one will fit straight in. I know the stock gtst one is 80amp and a gtr one is 90amp and i know that the positive bolt post is a bit bigger, i think gtst is 6mm and a gtr one is 8mm so that wont be a problem for me but i need to know which GTR one will bolt straight in to my R33 GTST, an R32 GTR or R33 GTR or an R34 GTR one

Aren't S1 R33 GTST alternators also 90 amp?

a31/c33,32,33,c34 stagea will work, the 2 pin plug is the same, the ground hole might be a tad different nothing a drill cant fix and the positive terminal can be flipped and used the opposite way if you have tabs on each end (or just trimmed ), might also need a slight drill pending application

ebay says r31 fits r33./r32 so i'd figure so

test your alt by putting a multimeter probe on the positive terminal on the alternator and the other on the neg bat/jumper terminal to confirm its not wiring like mine was

Have you tried looking at higher amperage after market alternators or example as follows with current price description and where to buy;

Advance 130A for R33 to R34 / black case with red pulley $ 574.18 plus freight

or

RH9 hyper-alternator 130A for RB, SR , VG series Nissan engines / silver case with blue inserts & pulley $ 554.34 freight.

from www.rhdjapan.com

just quote for either alternator from Compatibility list the more info the better and they will match to car model & engine type eg; RB25det etc.

Just remember to run heavier battery cable or get auto electrician to check your current set up

thanks for the info, i do want to eventually get a big aftermarket one cos i do have alot of audio equipment sitting there waiting to put in and its all old school kicker stuff that requires alot of power inlike there newer class D stuff but just for the moment i want to put a gtr one in cos mine is not working properly i think. And yeah im going to run all new wiring even on this alternator so when i do get a big aftermarket one it will be ready to go straight in. I actually started a new thread about wiring upgrade, i want to just use 8 gauge for the positive and negative and use stinger terminals and not the crimp on style ones i mean the proper thick allen key type ones but im not sure how the terminals will fit cos they must sit correct cos its not like you can bend these type of terminals to fit

Looked through my parts pile the other day, found a 90amp alternator that definitely came off a stock S1 R33 GTST. So I bolted it up to my engine

[Mick]

are you saying that a series 1 gtst has a 90a and the series 2 has a 80a?

[VLSteve]

Yep, over the past few years, I've bought 2 S2 engines and an S1 from a crashed stock skyline that I bought for parts, and both S2's had 80amp alternators and the S1 had a 90amp.

I even did a search on this forum which told me pretty much the same.....

[Mick]

thankyou so much that helps me out, im guessing the s1 will fit the s2 which is what i want

[VLSteve]

Yep, this thread is what reminded me I had the 90 sitting around, bolted straight on to my S2 RB25DET which is sitting on a stand at the moment.
