Lithium

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.

Have you mounted it yet?? You should find it doesn't look tiny, we've had a GT3076R and a GT3582R next to each other - the GT3076R does not look a hell of a lot smaller at all. 2Rismo - considering GT42RS?? Why did you bother going a GT3582R if you had the idea you might go something that big down the track

Trust/Greddy = Mitsi Blitz = KKK HKS = Garrett Apexi = IHI They all do things to help the turbo sold suit their application a bit more than buying something directly from the non-aftermarket manufacturer. HKS (as said a few times) offer some wheel combinations you wouldn't get when buying a Garrett "equivalent", and use a different ball bearing cage to what the Garrett units do - Garrett use a "plastic" cage which can fail, especially with insufficient cooling hence you NEED water cooling with Garrett turbos. I believe HKS use something a bit more resiliant?! Could be wrong though. Just the little things, though the only thing that'd have swung me to getting an HKS GT3037 instead of a Garrett GT3076R would have been ease of install if the price had been more comparable at the time.

Yeah the "good setup" thing runs very true here, I have similar power on exactly the same dyno as Nizmo_freek, at least as good tires on higher profile 17s, but stock suspension. I cannot go more than half throttle in first gear, and even then that sits it right at the limit of traction - second gear is fine though unless I shift gear aggressive. A rapid shift into second will result in more show than go. In the wet, rolling onto the throttle in 1st, 2nd or 3rd can be iffy... suspension is right up the top of my "next mod" list.

Yeah its Psymin - and the times it has run are not that flash at all for the power its made, hub dynos read higher than Dyno Dynamics BUT that is still slow for that power on that dyno. Is yours still a 2.6?

There is a chap in NZ who has a 800hp Stagea using an RB26DETT converted to single T04Z, it struggles to go much faster than around mid 11s on the strip though I figure the 2.6 is far too small for the heavy thing.

The only GT30 that has the T04S compressor cover is the GT3082R, unless you count the weird ball bearing GT30T04 thing that some guys in Ozzie end up with. GT3076R is a .60a/r antisurge cover That turbo looks like a weird Ozzie GT30T04 76mm thing with a VG30 turbine housing bored out to fit the turbine wheel.

Not true, higher revs add a far greater load than increased torque on an engine. You can double the power of an engine using boost and the same rev range (provided good tuning) while adding only a percentage more stress on the bottom end - well short of 100% more. Its pretty much the opposite for extra revs, add 25% more rev range to a car to make only a little more power and the stresses on the bottom and top end go through the roof. The trick is that a large amount of the stress on rods etc go into accelerating and decelerating the pistons/rods in each direction (with the rods holding a lot of the force). Putting more boost into a motor will not add to net effect of the of the reciprocating masses, revs does.

13.3 @ 112mph I'd post a time slip but its a huge pic. That was done with no boost controller it was effectively boost creeping, until it finally reached 1bar and it would stabilise a bit. I needed to be well into 3rd before it reached 1bar of boost, so first gear was no/hardly quicker than with a stock turbo (running 11psi pretty much) and then built up from there. By 3rd is was starting to stomp. Since then I have put an AVCR in it and the comparison is night and day from back then - on the dyno it makes pretty much no peak power difference, just that in first and second it all comes in and the midrange feels WAY better. It was also lagging a bit on each gear shift prior to the boost controller

Yeah thats a fairly good point, if thats in 2rd - mine gets a lot more savage than that and romps through second. Makes the pretty noises too, but probably a fair bit cheaper setup - and only running conservative boost. The GT2835 vid posted in this thread sounds like it'd give it a spank Heres a clip with mine when I got the internally gated housing, before I got the boost controller for it: http://www.youtube.com/watch?v=1tajFNv_q7Y

This is interesting to me - GT3071R and GT3076R being capable of similar power, cases I have seen at least the GT3071R (at least on our hub dynos) start falling over just above 300kw where the GT3076Rs can start pushing higher than that. You probably need cams to really utilise the higher flow of the 76mm compressor wheel though. I know people have got well into the 350wkw area on hub dynos with them on pump gas, or over 370kw on race gas with the right setup.

Haha I have a fair idea of what a setup like yours drives like, and I recommend semi slicks being a permanent fixture to the back of the car

Most cars are around 1400kg these days, all the EVOs etc have porked up to that kind of weight. There isn't much you can get modern which is much under 1300kg. And in terms of fuel, you just described the state in NZ - 98oct is $2.04 a litre at the moment

Very nice video Was interesting to observe, I can't tell watching it if my turbo (.82a/r GT3076R) is any laggier - nothing obvious thats for sure . Something else which is interesting is your car is definitely a bit quicker than mine, I have made very similar power number but on a hub dyno so all it does is confirms what every already knows - hub dynos read a bit higher haha. When I sort a couple of things out I am tempted to try a 17-18psi tune and have a blat at the local race track (I actually have one 15mins drive from my house!! ) and see what mine does the rolling to 200k thing like. Should be good for some rapid 1/4 mile times like that, especially with some sticky tires.
