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.

Going back to the Super responsive ATR45SS turbocharger, now fitted to an stock Rb25det Neo motor. High mount externally gated setup on E85 fuel. Car made 390rwkws @ 26psi, 22psi @ 3500RPM.

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.

    • So next year I am looking at upgrading from my VE SS bomadore ute to something more refined.  I wanted to stick with a V8 but not anything German or Australian, either a coupe or a sedan. So if I wanted anything newish that limited my options to either the Lexus RCF which I quite like. But with the price they demand and a kid on the way a 2 door coupe is probably not going to be the best idea. The next best thing would be the ISF but the newest models are 2014 and commanding over 60k and even the older 2008 models in ok condition starting around 35k is kind of bullshit. So I figured if I could not have the noise I could perhaps make do with easy power. Enter the infinity Q50 or Skyline equivalent. The price difference between the 300 and 400hp models seems a bit crazy. Right now there is 300hp Q50 one on carsales from a dealer with 61km for 27k drive away. If I wanted to get a 400hp Red or 400R car the prices seem to start at 43k From my limited research it seems that the only differences are that the 400r/Red Red runs more boost and a more aggressive tune. There are are turbine speed sensors on the turbos. Has 2 pumps for the water to air intercooler. Runs an engine oil cooler. I'm guessing that the exterior trims might look a little more sporty as well. I had a lazy look for upgrades to bridge the gap on z1motorsports They have kits that upgrade the water to air heat exchanger as well as the coolant pump which should give a non Red/400r better intercooling temps than the stock Red/400r. I added an engine oil cooler with a thermostat as well to try and make things as close as possible. Obviously the ECU is going to need a tickle. Having not done much in the way of research they also sell a ECU flashing tool with pre loaded tunes that are supposed to boost the non Red/400R by 100hp which adds 1k USD to the cost. The total cost of the parts @ the current time including shipping and taxes worked out to be $4350 AUD. Personally I would rather get the car tuned on a dyno which would probably add more cost Assuming the worst that you got a workshop to install the new parts I would guess no more than 5 hours would be required in the worst case @ 5 x $150 per hour = $750 So the total cost could be around $5100 So for easy number 5k + 27K = 32k I guess that would leave some change left over to swap out the open diff and fit a LSD Any thoughts?      
    • Right, not sure why I thought it to be a lean spike. It might be fixable with modern card-style hot film MAFs which have some design features to avoid counting reversion flow but I've never tried it myself.
    • I did not realise this, I'll contribute more and earn my stripes and retry later. 
    • I'm only going to hassle you for posting links to images. It's against my policy to click links that could be some nasty payload. Sadly, you need to make 9 more posts before you can just stick the images directly in a post, unless @PranK sees this and bends the rule for you.
    • Hello,new to the group, I bought a R32 from auction recently, wondering if anyone knows the cars history, seems to have the usual go fast bits on it, plan is to do an engine swap- add 2 extra cylinders and 1 extra turbo. https://www.dropbox.com/scl/fi/i4rjmlzubjbwjtguh6f4s/IMG20241011140744.jpg?rlkey=q0lumm251377vknbqktfwrycq&st=7scvwx4e&dl=0 https://www.dropbox.com/scl/fi/ro24qmwzlczzlfsr4y05x/Screenshot_2024-10-10-10-49-23-90_9a2f5bb2149dae94cd1e190effc09b33.jpg?rlkey=oyguh26ttshlf04ccp48odf4v&st=xloae97b&dl=0   New to forums and posting pics, if links don't work, take it easy on me, 42yrs old and I tune carburettors!!
