No doubt, mine isn't getting pushed at all and it's starting to get right up there power vs power rating wise.

I just find it hard to imagine a larger turbo on basically the same motor set up as mine and Jez's is making almost double the power at 4000rpm and a huge extra wack of hp top end... All while being on 99 octane fuel vs Jez and myself on E85

If I thought that graph was genuine and repeatable I would have already sent an email requesting an invoice for the purchase :)

Any thoughts on how it is possible? I agree, it seems unbelieveable - but there has to be an explanation! SAE doesn't inflate numbers THAT much unless the temp sensor is somewhere silly, perhaps.

Might have to check more MGT dyno results to see if they have other numbers which seem too good to be true - they are meant to be a reputable outfit.

<edit> I think I have found a trend :(http://www.gtr.co.uk/forum/176121-high-power-rb25s-mapped.html

Lol you are everywhere when it comes to turbo results :P

Probably wont be able to get much help here but what would you guys recommend for a n1 motor with vcam?

6262 .84 twin scroll seems to be the go for a 26 but with vcam would the 6266 be the better choice with a bigger rear (1.0+).

Car sees a little track mainly for street though and will be run on e85. Ideally I'd want 450awkw+

  • 2 weeks later...

i rekon a 6266 .84 divided rear would be choice

I got that same turbo on my built 26, still have standard cams, e85 etc getting tuned Friday so I can post up a graph then, will be good to compare to all the 6262 graphs getting around

Update guys, The Old girl made 350kw 15 psi 430kw 24psi, 30psi made 436kw @ 6000rpm ignition prob the splitfires arent coping plus Im thinking the exhaust maybe holding it back 3.5 inch dump pipe 3.0 inch exhaust maybe to much back pressure we will check & see whats going on. Should be up around 500 plus in my eyes gate is vented straight out with screamer pipe. Need to iron out the little bugs then hopfully see some decent numbers.

Very nice mate!


When does this all start to happen, RPM wise?


I would have to agree that 3" is too small for any part of the exhaust when reaching for those power limits.. 500kw is basically 4" TBE zone.

Didn't it make good power on pump gas? If it can made 450kw on straight pump gas then it should be able to make a fair bit more than that on E85... if it isn't then the cause is more likely to be ignition or something along those lines.

to put it straight Lithium, The 450kw was on race fuel at autosalon with to4z .82 rear 24psi, was making 430 on pump98. Just its really bugging me that it seems stuck at 400 plus. In all Honesty it should crack 500 plus @30psi one would think engine sounds great. Did a comp test evrything is good 134,134,134,135,137,134. Thinking either LS2 coils or okada what your thoughts about the situation?

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
