Hey guys, I'm looking at buying a late model R33 GTS4 and doing a RB26 conversion. Has anyone does this before?

Just wanna know what I'll have to change in the drive line.. like Gear box etc..

Just curious to know if the R33 GTS'4 use the ATTESA system like R33 GTRs?

thanks guys..

Yes. They use the same ATTESSA as GTR.

Its not the exact same gearbox as GTR (shorter gears) but stronger than GTS

You will have to upgrade fuel pump to match the 26's needs.

Other than that. Its all very straight forward

So the Drive line is strong enough as it is? Dont need to upgrade beside gear box clutch?

So if i was to buy a late Mode R33 GTR half cut... with Box and ECU loom.. etc.. all that stuff..

Everything will bolt in fine?

all depends on your drive, if you're dumping the clutch from the rev limiter constantly and side stepping the clutch during changes then don't expect anything to last long.

The car will be driven to its limits on the track... But on the street just the usual burst here and there...

Should be alright I'm assuming...

i hate to be a smart arse, but nissan did it. They took a gts4 and put in a rb26 a well as giving it a wide body kit and some more guages, among other things.

They called it the skyline gtr.

Seriously though, why do you want to go down this path? Cost? how much do you think you will save? Something different perhaps? Found a cheap gts4? Doing it for a challenge or hobbie? etc...

gearbox will be fine

rear diff wont be

its not a small job, like any conversion, its gonna cost quite a few $$$.

Unless you were getting the gts4 really cheap, i would sit down and do the math and see how much you're going to spend. With the price of r33 gtr's these days i think you'll find that it doesnt work out that much more to get the real deal.

But its all apart of the fun, if this is a project car go do it and you'll learn a whole lot, but if you want it as a daily save up that little extra and just get the gtr

I bet you will be half way thru the conversion and say to yourself "i should have just bought a bloody GTR"

If you do complete the GTS4 RB26 conversion, it still will never be a GTR.

Never want it to be a GTR.. just a street sleeper.

Im going down this same path with my R34 GT-four. Hoping to bolt a RB26/30 into it later this year. Will let you know how i go. I'll make a project build thread sometime in the year.

I did it with my R32, now i have a 316kw GTS4. Would have been heaps cheaper to just buy a GTR but that depend if ya gonna do the work yourself. The look on peoples faces is classic when you blow them away at the lights :)

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
