The .82 exhaust housing is the best option for the Gt30r. The open scroll housings flow a lot better and the .82 is the winner here. I've seen guys make 550whp on that turbo with that housing.
I would be hard pressed at this elevation to really push the turbo that hard. The only reason I really went with the 6262 is because I want to hit that number of 500whp. And I want to do it on this tune, with less than 25psi of boost.
I am excited to see the difference the turbo makes. I feel like the setup now is how I always wanted. Its responsive as hell, feels amazing on only 10psi. But high boost numbers seem to fall short of my goal, and the turbo seems to wheeze at this altitude. It feels great, but I don't really feel like pushing over 30psi to reach my goals.
The other downside, is all that torque. It likes to break things. Things that cost money. Here's how it stacks up. In the past 2 years, I've broken:
3 Axles. 4 clutches. Broken 1 input shaft. 1 final drive. 1 2nd gear. 2 3rd gears. 1 4th gear. Gone through 6 transmissions total. Smashed one prothane rear mount, and broke a stock front mount that was window welded. All from 400-448lbft of torque and no wheel hop.
So my goal now is to lower torque just slightly, even though the RS6 transmission is stronger. And to hold torque out to 8k, with a 9k rev limit. Make more power with less boost. And not turn the engine into a DOG in the process. I feel the 6262 will meet those expectations. But who knows how this engine will respond. I could make ridiculous power gains, or just modest gains. Either way, I'm hoping the gains outweigh the loss of response.
I've seen insane numbers put out locally with this turbo. 15-16psi making over 400whp on single cam hondas. It will be embarrassing to see a D16 making more power on lower boost than the almighty SR20VE, and I refuse to let that happen! lol
