hey all

i have a 1994 R33 GTS-4 and i want to put a RB26DETT into it

i'v been told that i have a drive train like the GTR?? is this true?? i have the MT gear box and i was told that's the same as the GTR box??? and that the 26dett will drop straight in?? are these ppl full of shit?

i can't seem to find much info in the gts4 so i'v just been going on what ppl tell me

i want to know

1. if my drive train is the same as the GTR or how much differaint is it??

2. to put the 26dett in what will i have to do and change? like diff, gearbox, drive train? wireing? any of that stuff?

3. what parts will i need to get? other than the engine :)

4. if it's just all to hard and i should just get a RB25DET??

if there is any thing i have missed pllz tell me

thanks very much for your help!!

Rb25DET is not a GTR. There may be shared components but I don't think the GTS 4 drivetrain and diff is as strong as the GTR. I have heard of quite a few R33 GTS25T's that have had an RB26DETT swapped into them and i believe an R32 GTS4 has had the same treatment, so it is entirely possible and you might have to swap in a GTR diff + GTR ECU.

It will fit in the engine bay

That's the R32 GTS4 in Hi Octane ..

It's true that the R33 GTS4 missed out on all the good stuff, unlike the 32.

In the 32 the g/box is the same as the GTR, but I'm not too sure about the 33. It wouldn't be too hard to bolt in a stagea motor, but then again it wouldnt be too hard to bolt in the GTR motor either. YOu're just going to need all the ancillaries as well.

i know i have missed out on the 5 stud wheels, and bigger brakes, and bigger clutch and lots of other good stuff the GTR has

i want to find out if i can kinda get the same specs as a GTR coz i'v been told (by some one who imports 1/2 cuts) that i can drop the engin straigh in, the g/box is the same and every thing will fit.. but i have a feeling that it not that simple and i just want to knwo what i'm getting into

u think getting a wrecked GTR and changing all the bits over would be the way to go? would they all fit? or can i get away with just getting the engine and other bits?

your better off selling it and buying a gtr, sorry dude. given the cost and the amount of shit you'd have to change its probably cheaper to just a buy a gtr. there's so many things you have to change, notable the drivetrain in the gtr is attessa, whereas its something else in the gts4. of course feel free to search and what not, but theres a lot to be done, even if you can just straight swap the engine, which you wont be able to do most likely.

brakes

ecu

clutch

diff

drivetrain

what else?

Jimbo2000: yeah you can put the RB25 from the Stagea into the GTS4.

Paul: the attessa is the same in the GTR and the GTS4. THe engine will indeed be a straight swap, though as you put in your post the brakes, ecu will need to be changed. The clutch well yes you'll need a HD item. The diff is a different ratio and will help you get out of the hole quicker than a GTR. You'll be slower in the top end though. Drive train is essentially the same.

Not sure if the 33 gearbox is the same as the 33 GTR box. I know the 32GTR and the 32GTS4 share the same box.

But if you're not going for looks, only putting the motor and associated parts in, it won't be cheaper to buy a GTR.

I'm pretty sure the gearbox in a R33gts4 is not the same as the GTR model due to the Gts4's n/a specifications. Honestly, i reckon it'll cost too much since you have to consider so many other mechanical alterations as aforementioned. HPI did a comparison on the R32Gts4t & the R33Gts4 in an issue not too far back - The one with the red s15 on the cover as I recall (Issue 36) . Anyway the short of it was since the R32 was already turbo and shared similar specs with the GTR, i.e. gearbox, etc - The swapover for an RB26 would be easier & more cost effective. This is a common question asked by MkIV non turbo Supra owners as what they'd need to do to make their n/a ride into a twin-turbo beast and is it more cost effective - The answer more often than not is DONT bother, as it is economically crazy. I've got a 32 GTST with an RB25DET swaped in (engine work done here in Oz) and this has caused enough headaches with tuning & parts as it is. This is not including the additional costs such as acquiring a RWC for the car with an engineer going over it with a fine tooth comb which isn't that cheap. You might start to think going the GTR route wasn't such a bad idea afterall - Then again you've got to consider what you want the car for and do you really need that much power? Why don't you just do a trade for an R32gts4t or sumpthin? I saw not too long ago in the Trading Post for sale an R32Gts4 with an RB26 swap - Going for something like 20g's....maybe something to consider. By all means it should be possible to drop in an RB26 into a 33Gts4.... just takes money and some weighing up decisions. Anyway hope this helps! Goodluck!

      @joshuaho96 Hmm considering the drama you've seen/experienced, have you looked into getting a built complete long motor shipped from Australia?  Considering the AUD is basically monopoly money when compared to the USD, at a glance this seems like a good option?

      Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!

      I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).

      At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself

      I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad.
