Just scored myself a GT35/40 from an XR6 Turbo, was wanting to know if anyone has fitted it to there R33 RB25DEt. What sort of modes were needed to fit this to your car? Already have a FMI, 3" exhaust, Splitfire coils, pod filter and Haltech ECU, also planning to get pump, injectors and regulator. Any suggestions on which of these i should get will be great and websites to look at. Have got 200kw ATW from stock turbo and modes with 10psi, can anyone estimate what i can expect to get without doing damage to bottom end?

i have one.

u will need... a hi mount...good luck with a low mount :S

dump pipe,

wastegate, preferably 48mm

braided lines.

u will need to change crossover pipe to accommodate the hi mount, or go a greddy plenum.

u wont need a ecu if u want to putt around.

u can use stock injectors.

note* bottom 2 are only for a short period of time at minimal throttle.

theres a bit of debate, i was told it was a 600hp turbo. but on your setup 300kw to 350kw would be achievable

nengun.com is a good site.....but post is a bit slow

Hi,

More then a few people have put a XR6 3540 onto their stock motor. Only last week there was a guy playing with rear housings.

As for sites and locations for the information you need, SAU is one such place. You just need to locate the information.

Id think you can made the 300rwkw on ~1bar that every one else makes on a stock motor.

Cheers

This was covered mid-late last year mate

And another GT35 thread

Exact same thread, with exact same questions :yes:

Enjoy the reading as there are a few threads linked in there also with some extra information.

cheers

    • Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.  
    • Welcome Adam. Car looks great!
    • "With a 1.5-WAY, the LSD is effective only during acceleration."
    • Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020
    • I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.
