Ahh yeah sounds like a good idea, on both levels 22psi is pretty much where I'd be going high boost as well. 20-22psi is high but really a safe limit for pump gas, so long as you have a good tuner etc - I know people running way more than that, but they are certifiable. Really looking forward to seeing the results on 20-22psi, it should go very very well.

NICE! Been keeping a real eye on this thread, will help me decide on whether to keep the GT30R/RB25 combination How hard are you going to push the tune when you do it? It'd be rude not to crack the 20psi mark!

Haha yeah, "7s is imanent". Done 8.4 in his hands after a bunch of "improvements" so far. Will be interesting to see how it goes

AHHH so Duke DID do a 7, I had in my head that they had but when I searched around I couldn't find any proof of it.

If you will be using the original turbo, you won't be making 350-400hp You will blow your turbo up before needing bigger injectors. Don't push the stock turbo over 12psi tuned, in my opinion.

Your shift point shouldn't be at peak power, it should be where you have got an optimal area under the curve. I aim for ~500rpm after peak power...

I have mine set at at 7200rpm rev limit, no problem so far.

A plate on the exhaust wheel?? Are you sure? Either way, HKS don't create the wheels - though cast their own housings in some cases.

HKS were 7.67 @ I think around 182mph and Heat Treatments are 7.57 @ 191mph. Those are the only times to beat that I am definitely sure of.

AWESOME! Congrats, thats great to hear - I ran on street tires with the same turbo, same boost and got the same time on them and have been intending on running my next meet on Micky Ts as well Fair to say I might be able to pull similar? I'm actually looking at raising the boost a tad too.

Absolutely outstanding work - one of my mates was there keeping me up to date and said he got to meet you, and said nothing but good stuff about you guys and your car Wish I could have been there to see it. Hope you guys get to go quicker, and that whatever happened on the last run wasn't too major

ATP's T3 flanged 5bolt one is a proper one You just need a XR6T style dump pipe.

My car running a .63 Garrett GT3076R was not any worse to drive than another R33 I know with an HKS GT2535. Under 3000rpm mine didn't build boost as fast as the GT2535, but whats the point in that? Below 3000rpm is not the fun area - its the area you want to potter around in and get fuel economy... not making lots of boost. I am pretty confident what I said up there is true...

Is another Oz GTR going to be there gunning for 7s?? I heard rumour GTR700 might be making a come back.

Yeah I wasn't going to say it, but its certainly true. 2.6litres is certainly very very impressive though given its not the original engine spec, the fact that its not rounded to 2.7, 2.8 or whatever litres is pretty academic. I personally wouldn't want to taint the sheer awesomeness of the achievement Mark and crew have done by making up world records for it when the short of it is it is one of 3 GTRs in the world who have managed a 7 after years and years of top tuners and big spenders making huge efforts to do so. Its an epic achievement and its clear that it could still go faster. Top effort guys

It takes nothing at all from Mark and crews achievement due to it being a drag chassis but it still doesn't change that the car was running a rb26 so no one can claim faster rb26 until they beat its time.

Yeah, if they can go a little quicker they will be able to too The mid/high 7s RWD Sentra from the States is still 2.6

Awesome! Congratulations! look forward to hearing how it goes tomorrow

Awesome, exciting stuff 173mph is certainly getting up there, fingers crossed it can get those extra few mph and a 10th less - would really like to see this car as the next 7s one! Good luck guys.

My vote is definitely bigger turbo. Enjoy it whenever you want, and if you go too big - then you can go NOS Ohh upgrading from the GT-RS?? Single turbo time??

Very cool - good luck guys What tires is it running on now, I am assuming full slicks?

To be fair the RBs fail at NA. I'd be much more inclined on going a different car or going to the length of transplanting a VQ35 or something like that in it. The VQs straight off the bat make more power than any of the non-GTR turbo RBs, and respond nicely to mods. If you kept the hood down, you might even be able to pass it off as a normal NA skyline

As far as I know this car is comparable (if not faster than) to the Zen Performance WRX also from the UK that went to Japan to compete in Revspeeds super battle at Tsukuba that ran >1second faster than the "all conquering" Hioctane racing R32 GTR

I vote, very very very hard - that you DO NOT go GT3082R. Max out the GT3076R first, you may be surprised at what they can do. If its not enough, don't mess about with the GT3082R - go to the GT3582R

Haha I know the GT3582Rs are underestimated by many, would love to see one pushed to the limit on an RB25. So long as you go 1.06a/r turbine housing you will possibly blow people away, I've known people to run near 150mph on them.
