I've got my rb20 up to the level i want and i got a z32 maf and gtr injectors with resistor sitting on my shelf. My car has a JUN style plenum, 4 3/4" thick intercooler, 3" piping, NISMO fuel reg, 255lph pump, racing clutch, flywheel, top mount turbo manifold with a .50 ar to4e turbo, 40mm Synapse wastegate, and i just finished fabricating my dump pipe and a screamer pipe so small it'll fit in the palm of ur hand.

Can i install the z32 maf sensor and or injectors before i can get Nistune software? even for a little bit? I heard of guys changing their stock maf to a z32 with no tuning and they claimed it worked.

??

sorta, my top mount was this years project and i have yet to even start the car for the first time, everything else was done last year and worked very well with my mines tuned ecu. I just need to locate the damn o2 bung that i misplaced and weld that in place and build one 90 degree bend to tie the turbo into my charge system. I dont really know what boost i can run with the stock injecors and the larger turbo. I peaked at 1.4 bar last summer with a tdo5h 16g and dropped to 1 bar, but i think even 1 bar at 8000rpm is allot of air to fuel with the to4e.

Do you think running over 1 bar would be pushin it?

    • 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 👌
