Yes thats right. R32 GTS-4 had RB20 turbo engine, and R33 GTS-4 has the RB25 normally aspirated engine only.

I have been looking for an R33 GTS-4 manual for over a year, and cannot find one that is for sale, but they do exist. There are quite a few automatics around, if that is what you want.

Yes the R34 does come with an RB25DET plus AWD, but it would not come cheap.

The best option is to get an R33 n/a GTS-4 and turbo it yourself, a bit of work, but not impossible.

Another way would be to fit an RB26DETT to an R33 GTS-4, now that would make a very nice sleeper, and at around half the cost of a GTR as well.

If you bought an auto GTS-4 for about $15K, a complete GTR front cut for about $10K, you would have absolutely everything you need, plus you could flog off all the unused bits and recover a few dollars.

Well.. I'm in the US. Skylines are a tad bit scarce here.

These pictures are the engine swap I'm buying, which has come from japan. And I really cannot find out exactly what it came from. All I know is that it is an AWD R33 RB25DET automatic.

I gather it's either from the Stagea or some sort of GTSt-4. It doesn't really matter, but I have been looking for information on it for a while now. And everytime I mention this engine or show pictures of it to people here in the US (or on a US Nissan forum), they think it has been modified in some way. I'm trying to figure out the truth. I know there was alot of variations of skylines out there.. but I've found no real information on the exact models and editions for each year. It obviously looks stock and unmodified IMO.

If it is from the Stagea though.. it is definetely rare. Because what I'm gathering is that there was only one year that the stagea even had the RB25DET AWD, and that was 96. The others were called VQ25DET's..

Who knows. Thanks though.

Very interesting EJ6. The RB25 block used in the AWD version is different to the "normal" RB25 block. The oil pan rails are quite different, and some of the holes are much larger to take the studs which secure the alloy sump and front diff.

So there is the RB25DE, and RB25DET block used on the R33 and R34 rear wheel drive cars, and then there is the RB26DETT, RB25DE, and RB25DET neo blocks as used in all the AWD versions.

Your R33 has definitely been modified in some way, and there are two possibilities. The original RB25DE may have been fully rebuilt with all the RB25DET parts, but using the original (AWD) bare block, this is possible, but highly unlikely.

The other possibility is that someone has dropped in an R34 Stagea RB25DET neo engine. This engine is different in many ways to the original RB25DET, and is rated for 205Kw, if I remember correctly. There are many detailed changes including variable valve timing on both cams, and the top of the engine looks totally different. It should have "neo straight six" prominently displayed. If it does, you are a very fortunate fellow.

Warpspeed, thanks for your help with this..

I've also heard that the RB25DET stagea is a bit more powerfull. I hope to god this is it, because that would be one cool thing.

It doesn't look like a neo engine either does it?

Could it possibly be a R32 GTS-4 setup? I am being told this is R33. And it definetely LOOKS like R33.. because it doesn't look very old.

When I get the swap, is there a way of telling for sure or not? I'm familiar with honda's and they all have engine codes on the blocks. Does Nissan do this too in any way?

Thanks

      V37 Suspension change

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:

      R34 manual conversion speed signal wire finding, need help

      By GTSBoy · Posted

      Yes. Autos typically work from the speed sensor on the pinion shaft of the diff. I also think that even if you have a proper speed sensor for the bog manual in the manual box, that the signal it outputs is not compatible with the auto dash anyway. You should consult that manual (the book, not the gearbox).

      And I just realised that that advice is slightly nonsensical for a GTR, because you need 2 of them. But it is otherwise true.

      Duncan's V37.......race car?

      By Duncan · Posted

      Having had a reasonable look at the car, I'll be able to remove the (one time) rams and retract the hinge (they are held in the down location by a tiny (m3?) sacrificial screw) which will get it physically back in shape. From there if you remove the rams you need a resistor to turn off the airbag light (as Mark said, there are plug in kits and I might go that way because its reversible). And...per all the threads on here, even if you have the resistors to turn off the airbag light, the bonnet light will stay on as it writes to the airbag computer history - that is either replace the airbag controller, reprogam the EPROM (if I can work out how), or remove the globe from the dash. Having seen how sensitive this system is, if I had my time over I'd pre-emptively remove the rams, even on a road car, because this is all a very unnecessary pain in the arse. Reminds me, time to go and have a look at the Fuga too....
