i think mine is 5 hole? ill have to double check.

if all goes well im going to buy a R33 GTST ABS diff with half shafts tomorrow.

also one more thing, will the R33 diff bolt to the R34 GT25 NA tailshaft?

Let me know how it all goes once you get it done man, or do a write up, im getting tempted to weld my centre :P

^ don't weld it mate, makes daily driving a big fken nuisance (sp??) i had a locked diff in my old silvia, it was fun but very very annoying!

lockers have never really bothered me to drive with, probly a personal preferance, but i have resisted the urge to lock it n id rather sort out an lsd, so let me know how yours goes

good news, fits 100%!!!!!!!!!!!!!!!!!!!

for all you 25GT guys out there, rush out and buy a R33 GTST ABS DIFF, Auto preferbly (as its got teh same ratio, 4.363) otherwise a manual 4.11 will just be fine as long as its got ABS.

:D:) can do sick skids now!

f**king Excellent! My GT will do 2's with a bit of brake feather, but goes back to single as soon as you get more than like 30 degrees of angle, i know whats next on my shopping list :D

EDIT: do the stock driveshafts bolt up?

Edited by Silver_GT

yes, stock driveshafts bolt straight up, as long as you get a 5 hole type.

ive read up that the GTST ones are stronger then the 25GT but in a NA, it doesn't really matter as its not packing much power & wont know till it breaks and i replace it with a GTST item.

Yeah thats what i thought dan, pretty much the whole suspension in a 25GT is pretty much identical a R33 GTST.

great stuff, most of the r33 and r34 stuff is interchangable. When you say that you use the stock driveshafts, do you mean that you used the stock gtst 5 bolt rear shafts? Its just every r33 na diff runs the 3x2 bolt rear shafts, the same as my r34 diff atm.

If anyone else wants to do the conversion, best to use the stock gtst manual diff, the auto diff has a ratio close to 3.5:1 which isnt very nice for a low torque engine like the rb25de

I'll be putting the r32 gtr mechanical diff in my r34 in the next few months, i'll let you guys know how it goes.

Congrates, now for some skids :)

i used the stock R34 drive shafts (mine had 5 hole type not 3x2 hole). i thought the auto diff was a higher ratio, like 4.363? (thats what my search uncovered and manual is 4.11) I know R32 GTST run 3x2hole half/drive shafts

really 5bolt shafts? my r34 diff is the crap 3x2, must have something to do with the gtfour model.

4.3ish:1 ratio is the manual gts4, 4.11 is the gtr. Autos are definately much much taller gears, around the 3.5:1

Theres a bloke i use to know that had a auto diff in his r33 (was converted to manual) and the gears on that was redicously long, as in you wouldnt bother going back to 2nd at 50km/hr to give it some shit, you go back to 1st :/

Definately wont go well with a na skiz, way way too slow

My diff has a 3x2 shaft setup and its just a normal 2wd 25gt.I am now actually confused as to what diff I actually have, All i know is 2way diff ftw :D ...

All I want now is a set of 4.3 gears to make my car accelerate a little bit quicker...

Does anyone have some for sale here in brisbane?

    • I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.
    • 15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.
    • Mrs rs focus came factory with recaro cs  sportsters in it and they a pain in the ass to get in and out of with the really high bolsters, once you were in them they were one of the most comfortable seats I have ever sat in
    • The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.
    • Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
