1000whp 300ZX is not something I come across every day. Powered by two of our ATR43SS-2 turbos externally gated on E85 fuel. Dyno maxed at 905rwhp @ 35psi

 

Actually Tao, Prabaths 300ZX did 940rwhp on Trents dyno maxing out the torque at 1200nm.

I bought a 21u g3 used and it has minimal shaft play side to side , none front and back, and doesnt rub anywhere. previous owner said he ran at 19psi on rb20. do you think i should be concerned with the side to side shaft play or is it acceptable?

All turbos need to have a small movement in the shaft as the bearings relys on that clearance for rotation and oil delivery, you can that as bearing clearance. I say there should be nothing wrong with it since it came out of a fully working car. Assume its a bush bearing high flow, must make sure it runs an -4 oil line with no oil restrictors.

Updating on SAU about the latest result of the R34 GTR test car:

Back today at chequeredtuning with Tomei Pon cam Type B installed. Pretty interesting result to share as I never though it would make so much differences on a Rb26 engine. Using the same turbo and nothing else changed, car ended up making 444awkws @ 23psi, compare to stock cams, it made 31kws with 3psi less boost with waymore mid top end torque. It wasn't much laggier in response either. 

Car has:
Stock R34 GTR Rb26 with APR head studs
HKS Cam gears 0 inlet, 0 exhaust.
Tomei 260 / 9.15 Pon cams
R35 GTR coil packs
Trigger kit
ID 1650cc injectors
Twin 540 Walbro pumps+11m fuel line
Apexi FMIC
Trust 3 inches turbo back exhaust
PS2000
Nismo Front mount cooler
T4 high mount exhaust manifold
HyperGear 50mm External gate
HyperGear ATR45SS-1 Rb26 T4 Vband rear turbocharger
Final result of 444awkws @ 23psi

Twicked this turbo alittle bit, Made same power, picked up another 500RPM of response and 100kws in mid range at same boost level or 23psi, still running out fuel even with an extra pump.  I think the original version of SS3Pro would peek 70kws more at full capacity.

Very spicy, what dreams are made of. All in by ~4000rpm and making those numbers.

    • Nah, yeah, nah. Speakers have a nominal impedance of 8 ohm that looks more like 6.4 ohm when measured. The receiver's amplifiers (all channels) are all rated to 6 ohm (I think, it's been a long time since I cared). The real problem is that many modern class D amps have aggressive protection circuitry that cuts off the fun if they think too much current is being drawn. And with my speakers having series crossovers, as opposed to more typical parallel crossovers, and big TL enclosures, they can certainly dip down to lower impedances at some frequencies and that easily triggers the protection. Pioneer receivers are somewhat famous for it, but even Denon, Onkyo, et al, all have many complaints against them across various models. It only does it when listening to music at high levels. You have to be putting your ears at risk to do it. But sometimes I want to do that. If I was serious about using it as a listening room I'd simply upgrade the amp for the front pair to a nice Rotel or something, and just use the receiver for signal handling and processing - although that would be a bit of a pain in the arse too. Have to switch on more shit, pre-amp volume vs main amp volume, etc etc.
    • yeah pretty much, stopped playing after lightfall, couldnt be bothered with the final shape...  ran that game into the ground for years... bit of a shame.. the  story was awesome. was playing a lot of trials but the hackers became tooo much, ruined the game.

    • I reckon you are 100% right on the money. The only reason I bought Red Sport instead of the base VR30 is that I am investigating racing it in Production Cars, and they require you to run a (mostly) standard car....therefore knowing exactly what was in the RS spec was important to me and I paid the extra. Other than that, for sure I would have pocketed the $10k and spent them on mods instead. Plus the non-RS models are more likely to have had a nicer life prior. Just a warning though, mods always cost twice as much as they look like they will on paper BTW you should also consider the 400R imports, they are about the same price as a local RS but 5+ years newer. Of course that comes with the usual warnings about finding parts, unhelpful nissan dealers and finding insurance
