2.6 = 60's. They're still a 400 hp turbo each. The threshold might not be much on the V6 3.0 but it might be a different story on a shorter stroke engine minus 430 cc. The bigger engine will soak it up, the 2.6 needs all the help it can get.

How big is big?

Can't. Blew my gearbox up lol

Simon, in that first video it sounds like they're surging (not shuffle but surge). It could be just the video though. I have just done an overlay between your graph and mine. Obviously its a little rough but I was going up in 250 RPM points.At 4500 RPM we are the same, you overtake by a rough average of 20-30 kw then fall away at around 6300 RPM. Different dyno's and whatnot so it isn't the most accurate thing. Now, if you went from 550 WHP to 632 WHP (on this sheet you posted) and nothing else changed, then that is farken silly. Can you remember what boost level the -5's were running to achieve that? I spoke to the guy that tunes my car and he said to go the 63's. Now considering the -5's are a 360 HP turbo, 60's are a 400 HP turbo and the 63's are a 430 HP turbo, I'm not sure if I need the 63's. The 60's should (on my engine seeing that the -5's have already done 472 rwkw) do 500 with a much better curve to match (as you have not given away anything at any point), couple that with a 250 degree at 11 ish mm lift and it would be silly. What I am really curious about is that throttle response/lag between gears. It doesn't exist! Also, Gav from WA went from -5's to 63 mm GTX's and the last time I spoke to him, he was going to go the 67's. I wonder where our little rear housing is going put the white flag up and call enough?

Got an off the shelf kit ready to go? If so, how much?

When will you get the engine?

Say helllllo to twist

If they were -9's then they should be making more than 100 kw at 4000 RPM.Something is Definately amiss.

Very strange choice for a RP car, that's for sure. If it had a curve like that with massive 272's it would have been stupid with a cam in the 250-260 range, for sure!

Haha!!!!Do you know what cams were in it? There is still a little lag after a gear change with the -5's. It's funny because the 63 mm GTX is a larger wheel than the -5 comp wheel.

I'll play around with the graph tonight. Obviously different dynos and stuff but it will give a good indication.If they're 63's one could only wonder what the 60 mm curve would look like. Who did the machine work on the comp housings? You are an evil man posting stuff up like this! Compared to the -5's, what was the on/off/on throttle response like? Noticeable difference to the normal cast -5's?

Simon, were those runs done in 4th gear? It looks like it but it looks like it's only running to 7300-7400 rpm. In assuming 265/35 x 18 tyre with stock diff ratios.

I wouldn't believe that for a second otherwise the smaller versions wouldn't exist.

That is one angry looking car! Yum yum By looking at the engine bay and having stock pipe work I'm assuming you have the stock style comp housings? There is no denying that graph comparison, it's quite a significant improvement. What size cams and comp ratio is it? Being an ex Racepace car, they would be on the smaller side if not standard items unless you have changed them. Got me thinking about putting 60 mm versions in my own car. I don't want anymore power, just bring it in even earlier than it does. I'd love to know the weight differences of the cast -5 wheel and the 60/63/67 mm GTX wheels.

Depends if you want to spend the cash on the driveline. Area under the curve wins. Bugger that big dick number in the top right hand corner .

Interesting. Nice looking curve too. Any chance of a photo of the engine bay?

Yeah mate. It all came in a box. Everything you need, as you'd expect from Nismo.

Set that angry angry thing to soft! After "run in" use the OS GIKEN 80w - 250 oil. It will calm it down a lot. You'll see

Oh. Damn auto correct lol

Disagree with the holinger. Totally not needed and is a 30k investment by the time it's all said and done. Centre plate is a MUST!

Nismo c spec. Been in my car for 9 years, 40,000 kms, over 300 launches currently holding 472 rwkw. Good enough to just an OS GIKEN 5 speed. Lovely to drive. Ordered yet? Lol

Not sure on current prices.

Quaife or Nismo front, same again in the rear and extra few friction plates in the transfer case, commonly known as "the transfer case mod". Prob looking at $1800 ish to do the front, around the same for the rear and $600 for the transfer.

Haha. . Nah, I just keep sneezing and breaking stuff .

^^. After putting the Nismo in the rear, it has taken a bit of the front drive away. That GT pro is one aggro mofo. After speaking to Chris last time I was down, they do a few cheeky mods to it (which is no surprise). Mine is currently set on medium which is waaayyy too crazy balls. I'll back it off and when the box comes out, get the transfer case mod done. That should sort it out. I too would like to see how the Nismo front differs. With the stock diff there was a fair whack of torque steer, with the Quaife it's 95% gone I'd say. What you think is too early to get on it, it's not. I've turned around to redo the corner and basically get on it as soon as I tip it in. Best. Mod. Ever!
