maybe the way the power delivery/rev limit? (engine design)

there must be a reason 2jzgte never been used in JGTC while rb26dett GTR win more than any other engine equiped car.

True, the RB is more of a rev-happy race engine, the 2JZ is a hi-po street engine, for a street driven car extra displacement is nice (hence the run on RB30 conv. atm).

I've picked my self up a VG30DET BB turbo with plans to get it highflowed by gcg later on down the track. Anything over 250rwkw I'd be happy with. :(

For now I will be bolting it on with an adj. FPR (maybe injectors depends on $$) to see what she gets.

I'm expecting around 210rwkw peak some where around 5500rpm. ;)

Unfortunately I can't spend money on the highflow at the moment as I need to get the suspension and diff sorted.

The subframe bushes are nackered as is the diff, it now some times breaks out in to a single spinner when jumping on the gas in second, if it doesn't do that it breaks out in to a nasty axle tramp due to the stuffed subframe bushes. :(

do you know how much one is looking at to get a stock Skyline turbo high-flowed Joel?

My Neo turbo also has the plastic impeller - I wonder what the cost would be to change it to a steel one?

It comes down to you get what you pay for. As usual. :(

A cheap bush style highflow is around the 1k mark.

A BB core highflow is always up around 2k. GCG charge around $1900.

GCG are fairly well proven to highflow a turbo that is reliable and doesn't pop, I'll spend my money with them.

I could do the GT30/35 external gate thing but honestly big gates hanging out the engine bay really make me paranoid.

Sambo, Its making 175rwkw at 4400rpm then peaks up to 176rwkw (wow) by 4800rpm then drops to 176rwkw by 4950rpm then tails off to ~130rwkw or something by 6000rpm.

The stock rb20det turbo is waaay to small for the rb30.

It peaks to 12psi as soon as boost is made then quickly tails off to 9psi, this is on the stock actuator pressure. So the peak figure is made on 9psi, not too bad for a little rb20det turbo. ;)

The Rb20DET needed 15psi to make 164rwkw so it goes to show how much better the rb25 heads flow. :(

    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
