You will be hard pressed to find any on this forum with those turbos in a twin setup.

You would also assume anyone with those turbos would be thinking about power more than they are lag. Most people on this forum would consider ONE of them laggy making a little over 300rwkw. Two would be shy of double and obviously very laggy.

Yeah single form you are in the 300-330rwkw region on PULP.

So two of them, 650rwkwwould be a rough place to start the guess work.

If a 3076, smaller than a 3040... comes on round 3000-3300rpm in .86 form on a high comp 3lt, you'd expect about 6000rpm in twin, which won't have high comp given the boost that'll need to be used.

Depends on rear housinsg being used of course.

Hope there if a rev limit of 10,000 at a minimum :D

You chasing 600rwkw+ or not?

Some people consider that 2530s and GTRSs and GT2835s and GT3037s can be a bit lazy in twin form on an RB26 .

I think GTRSs is as far as I'd go on anything with number plates even on a 2630 .

IMO from the GT3037/GT3076R and up is getting a bit extreme on anything other than a single purpose drag car . Like most I've read articles on the Japanese with their denuded slingshot cars but they are not something most would want to use for anything else , basically bloody useless except for the very rich on a drag strip .

It takes a lot more that two bigish turbos to make a GTR a drag king .

I couldn't imagine an engine that was a clapped out Camry one to 6500 revs then an unguided missile thereafter .

Anyway on paper the HKS spec GT"3040"R , todays speak called a GT3082R , is a better one than the one Garrett generally markets though they've been around long enough its exclusivity rights to be over .

I'll look up the numbers later so you know how to ID each type .

The only real difference aside from a HKS turbine housing is the compressors trim which is 50 on the HKS variant and 56 on the one Garrett usually sells . Same comp housing same center section .

The cartridge numbers for the GT3040/GT3082R are 700177-9 for the 50 compressor trim HKS spec version and 700177-14 for the 56 compressor trim version Garrett usually push .

Sadly the 56T one was very common and there are a fair number of them in circulation .

My HKS list quotes the GT3037S 56T (port shrouded comp cover version same as GT3076R Pn 700382-12) as being 480 PS and their spec version of the GT3040/GT3082R (50 comp trim one) as 500 PS .

The reality of the matter is that half an RB26s 2568ccs or 1284cc isn't a lot to have to spin up a 500 odd horsepower turbocharger . Try to imagine a GT3040 on a Suzy GTi 1300 .

Correction **bottom of the mop bucket.

ive heard Hayabusa turbo's are pretty safe. i mean they only lift the front wheel from the power until about 280km/h n then its pretty stable...:worship:

Exactly the reason that twins on a 26 will be sweet, just raise the rev limit another 7000rpm and wheel stand goodness at 280km/h.

Actually Busa engines are not in short supply 2nd hand . You go down to your local wrecker and say I'll have that one , they wipe the blood and hair off and box it up for you .

The point I make is that 1000 horsepowers worth of turbochargers is pretty extreme for a 2568cc car engine if its used on the street .

    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
    • Well this shows me the fuel pump relay is inside the base of the drivers A Pillar, and goes into the main power wire, and it connects to the ignition. The alarm is.... in the base of the drivers A Pillar. The issue is that I'm not getting 12v to the pump at ignition which tells me that relay isn't being triggered. AVS told me the immobiliser should be open until the ignition is active. So once ignition is active, the immobiliser relay should be telling that fuel pump relay to close which completes the circuit. But I'm not getting voltage at the relay in the rear triggered by the ECU, which leaves me back at the same assumption that that relay was never connected into the immobiliser. This is what I'm trying to verify, that my assumption is the most likely scenario and I'll go back to the alarm tech yet again that he needs to fix his work.      Here is the alarms wiring diagram, so my assumption is IM3A, IM3B, or both, aren't connected or improper. But this is all sealed up, with black wiring, and loomed
