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.

the search button is cool! and your right this question does come up alot but it's all to do with the R32's!!!! i have a R33! and i can't find any thing on them ;)

My bad, I asumed you were talking about R32 gts4's ;)

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!

i got ppl saying it can be done and ppl telling me it can't and it will cost to much

i don't want to be rude but how do u know all this JiMiH?  

how do u other guys lear about the cars and what fits and doesn't???

Not being rude at all mate ... I myself have a 32 gts4 and am undertaking the GTR conversion :)

      What's this Foreign Object?

      Forgot to update. I ended up removing it and found out that it's dead. The car seems to run better than it did, although I haven't driven it hard yet. Literally just a flow restriction.

      BCNR33 Blower Motor Resistor - Testing

      ^ This is all good advice. I can imagine that there's some passive components in the HVAC controller that run that PWM output that could die, or suffer bad solder joints. It can be worth opening it up, taking a schmooze around looking for swollen electro caps, evidence of liquid escape anywhere, tracks that have been hot, lifted, cracked, etc. A DMM might not be suitable for seeing if the PWM output is pulsing. Might be too fast and too low voltage for a DMM to keep up. An analogue voltmeter might give a better hope. I use a handheld oscilloscope (<$100 from Aliexpress if you want something cheap). A DMM might see the voltage across the motor flicker. Otherwise, as above. If you can successfully see PWM action, then the control side should be good. If you can't see it with what you have, you might need to step up the instrumentation used, as above. Beyond that, and dbm7's advice on testing the motor directly, you're down to looking for broken wires, corroded connector pins, etc.

      R34 Gtt RB25det neo Issue After Modifications

      By ChrisGtt · Posted

      So Thanks for the comments etc. To follow up on this, we went down the path of fitting a divider down the middle of the external pipe that was added to the exhaust manifold and the divider went from very close to the external wastegate all the way up to the "V" part where the pipes from each side of the manifold joined. After this modification it was finally in a position to do the dyno-tune with some degree of success. Top end power was down about 10kw (250rwkw down to 240rwkw) I believe from previous but it seems to be more responsive lower down and at least it is now driveable and fun and back on the road to be enjoyed. Apparently the timing couldn't be run the same as it was running into knock and boost was down about 1psi. For all we know this could have been from the fuel being a bit older, or perhaps some slight complication from the new head gasket as we didn't have compression figures from before that mod to compare. I'm no mechanic and this is second hand info but I just wanted to follow-up to those that commented or read the original post with interest. After so many months of stuffing around this is a big win. The interesting part was most of the info around this was gained from information around Barra motors and not GTR as the manifold setup on the Barra with single turbo was more similar.  Thanks for those that helped with info.

      BCNR33 Blower Motor Resistor - Testing

      By dbm7 · Posted

      G'day ... first up, I very much doubt that's a resistor network (as used also for this job), but the part# looks right. The description of 'power module assembly' looks to be nissanese for 'PWM driven, ground switched, DC motor speed controller'.... the circuit in the schematic kinda infers that's the case... ...with the transistor symbol appearing in the unit described here as 'Fan Control Amp(lifier)'....being driven by pin20 on the HVAC unit,  and a feedback signal on pin19 from the motor negative terminal for some reason (might be motor fault detection, maybe they detect commutator switching to determine motor revs as well, I dunno)... but if they are  counting commutator spikes, a bad segment (or really worn brushes) will throw a spanner in the works... The motor itself will as said be brushed DC with segmented commutator, rated at 12VDC nominally ~ now-a-days I just unplug them, determine the positive wire, and hook them up to a variable power supply and find out how much current they draw, if they work etc etc ...you can also check for bad segments...ie; set the power supply up to feed 1volt @ 2amp max, then watch the wattage count as you slowly rotate the fan blower motor through a complete revolution ; any bad/dead segments will be clearly evident...some folks would just say determine the positive wire, and feed it battery voltage, and if fan spin, you've got a win...<grin>... well, at least that infers it should do something when plugged back in, and the HVAC unit commands it to run... and if it doesn't, you suspect the module, but you should check the PWM signal on pin20 is actually present, and if it is, blame the module ...
