Also looking at getting a PAR dog engagement gearset, 1st-4th, pretty cheap. Any reccomendations?

All I'll say is - do your research. Enough info just on this forum alone to make a decision about that type of thing...

Here's the setup I am currently running. Power is a tad over 900awhp or 671kw's @ 30 PSI of boost on E85 PB of 8.97sec at 150mph makes it 2nd Fastest Street Tyred Manual Gearbox GTR in the World -

PPG Dogboxes seems to be the strongest on the market at the moment, I have great results with mine. Just remember to upgrade the stock sandwich plate with a billet item cause if that fails then everything will as well. Have done over 50+ runs, all over 800-1000awhp going through it, you wear clutches out before the gearbox I highly recommend them.

Hi everyone,

About time we posted this up - here are the specs on our "NITTO" R34 GT-R:

STANDARD RB26DETT bottom end

ARP headstuds

Nitto Headgasket

Standard oil pump

Custom head by Mercury Motorsport

6Boost mani

Precision 7675BB turbo

Twin Precision wastegates

4" exhaust custom made

Haltech Platinum Pro ECU etc.

Upgraded fuel system

Splitfire coils

100mm thick FMIC

Custom i/c piping

OS Giken sequential gearbox

Power: 622awkw/845awhp @ 43psi (ran in 5th gear, to keep the 1:1 ratio due to gear changes, 6 straps holding it down)

Nicely done. It's no easy feat to make 850hp but glad to see you finally decided to run it and put the shit talkers to rest.

I can gladly agree that you indeed make over 800hp and am very interested to see you push that stocker as far as it will let you. At this point, even if it broke, you're currently making more hp than any other stock RB26 that I know of. Well done

Not sure if you are talking about Oz, or in the world... but Manny Cruz in the States claimed ~950whp for the stock bottom end RB26 he had in his Sentra drag car back in 2005, lots of people called BS - though the car ran mid 7s at >170mph and there is no reason for him to have lied about the internals - DSport in the US also had an R33 GTR they were claiming ~800whp for a few years ago with twin RX6s on the stock motor IIRC.

Not when it weighs 1700kg

It would either need that power with 1400kg to run 150 or it would need to make 1000hp at the weight it is.

Cheers Dan...

The Powertune GTR weighs 1800kgs including driver (we thought 1700kgs too, but speaking with Chea, it was 1800). Anthony & Trent are about the same weight & both cars are in full street trim with big brakes. We'll weigh NITTO in due course! :)

Mates vl calais 1400kg plus driver, with 385rwkw ran 139mph.

Same guy now has aprox 550rwkw vl running 9.0@155 mph.

I'd be more inclined to question those figures than Powertune's - but you can't compare them straight up anyway, unless the VL also bogged, and was running 20" rims wearing low profile basic street tyres. 142mph in a full weight honest street spec GTR with a 2.6litre engine (with stock internals so probably not big rpm) is insane, anyone knocking the time or power figures really outta take stock for moment.

I just copied this from another post......

I just ran our NITTO R34 GTR at the drags on saturday at Willowbank.

Ran a 10.39@142mph on Hero 255/30R20 tyres, Tein Monoflex coilovers, OS88 gearbox, standard 05U rb26 with precision 7675 turbo making 845hp @ all four wheels.

1.77 60ft

4.69 330ft

6.9 1/8mile (107mph)

8.799 1000ft

10.39 1/4mile (142mph)

Slicks and auto vs Street tyres and manual... Thus why you can't compare times and mph

      EFR7670 exhaust selection RB26

      By LegendGTR · Posted

      I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀

      Stock Airbox and Snorkle for RWC - VIC west

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
