Thanks for reply. That’s great result. What power it made on what psi? I’m looking for get 8374 iwg or 9180 iwg. But no result I can find.
Search my posts they are all on here including the build thread. 8374 is an incredible turbo for rb26

My R32’s previous config was setup as a Targa car, roughly 300kw @ the wheels using a pair of GT-SS's and some supporting mods. It was time for a change – my new setup is focused on track days.

Nice!  To be fair, this is a dyno result thread and posting a time slip but still no dyno sheet makes baby jesus cry.  Very interested to see the delivery of this

RWHP or AWHP?

465 HP seems a little high for a fairly standard 26 on -7's at 20 psi of boost.

Good result none the less!

RWHP.

The car did 384 whp before the stock AFMs cut me off around 17-18 psi...and at 10 psi did about 296 whp. Haltech, cam gears (rolled in about 6 deg of overlap) and intake pipes woke it up. This dyno is pretty dang accurate. Motor runs very well.

Also I just tuned another R32 GTR on stock RB26 on tomei cam gears, 8374 EFR .92 IWG, 6 boost manifold, on pumpgas 93 octane (your 98) and it did 570 whp on 20 psi. Did 636 whp on 23 psi on E30 and ran out of injector. Also on haltech platinum.

Both cars are strong...the -7 car definitely more laggy than the EFR single car though.download_20180806_220847.jpeg

480kw at 23 psi
 
Dam bald egles  can tune
This is how that car showed up on stock turbos, stock haltech igniton map and a rough (rich) fuel tune at 15-16 psi. However you want to criticize the overall power, the gains in power are undeniable with only a turbo, injectors, fuel setup, and cam gear changes.

Whoa... there is definitely something wrong with that motor if that's all they got out of an 8374 EFR .92 iwg turbo on a stock RB26! I mean how can the iwg be to blame when it's simply a turbine housing that's still in the range of what most choose on the RB if you still stay external? (Referring to the 1.05).

I thought you were mocking me with the bald eagles comment... no sweat there I have a sense of humor (hell yeah brother).

I'll get some videos of the cars this week for y'all

      What brakes on R34 GTT(Europe)

      By Dose Pipe Sutututu · Posted

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
