Dude.... I walked into a dyno shop which had 2x R33s out the front in so I assumed yeah they might know something.

I was like yeah I have an RB30DET, 40 thou oversize, big cams, forged internals, lots of head work, big injectors, big turbo blah blah blah...

Then he was like umm... why are you running a VL engine in your car..... I was like omfg I hate people who say that.. its an RB30 block with an RB25 head. he looked very confused and then said well $1500 for a tune. leave it with us for a few weeks and we will see what we can do.

A guy owns a performance shop here, I buy a lot of stuff off him and hes from QLD. He said that all of the tuners here he wouldn't even trust them to do a power run and that he is getting a tuner down from QLD to tune his car for him and hes going to hire a dyno for him to use. I am going to get him to tune his car for me when he comes down.

Well go to some one else who has half an idea. Unsure how it is in tas but in little old country town Adelaide we have over 5 good tuners. There's only one that I wouldn't trust with my car.

Im sure there is a decent tuner there in TAS surely there not all numb nuts.

Regardless there's nothing special about an rb30det. Its simply a stroked rb25 so a dyno would have shown there's a fuel issue; at that point the fuel return would have been dropped and straight away it would have been known there is a fuel supply issue. That is standard fuel supply troubleshooting regardless if he didn't know an rb30det existed or not.

If the dyno tuner can't do the above then he would not be operating.

I hope you have a little more luck running the 30det on the stock ecu than I did. Anything above 6psi at 3000rpm saw fuel cut.

:D

Ditto, CEF11E's remap sorted that till I could get in for a remap to suit z32 afm and bigger injectors.

Guessin that he has found a DYNO Tuner he can trust and that is not an idiot as he has finally got it booked in for a tune next week...

Or maybe I should ring Brad up and tell him some of the shit you been sprouting on here about the idiots that cant run dynos in TAS.

Seriously, do you think that nobody reads this crap you post and that it wont come back to bite you in the ass someday??

I am almost embarressed to admit that I have just bought a Skyline now.

Might go join a VOLVO forum...

but then your probably a technical expert over there as well arent ya Finny??? :ninja:

How much power are you expecting from your 25/30??? Or how much did it make???

Brad at boost automotive tuned my old RB25 to 399rwkw at only 17psi, and I will be taking my engine setup there for a tune also. With a big shot of NOS to get things moving.

How does a 023 pump compare to a 044???

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
