So how much longer?

Since you haven't ordered yet, maybe I'll chime in before you chuck another signature Rob :)

From what I understand, the 6262 makes a bit more power than the gt3582r, but is noticeably less responsive on the street & makes less midrange. Nothing in turboland comes free. The 0.82 rear would make it larger & a bit less responsive than my GT3582R on your motor (larger inducer I believe). Not sure if that's a good idea for your setup considering your 2L displacement, block & rpm limitations.

You'll undoubtedly make more power (still a great turbo), but IMO it will not make for the greatest drive. That turbo on a 2.3L 4G63 is brutal past 5000rpm, so I can only imagine a 2500-2700rpm power band for you (approx 5400-8000rpm). Josh from the States ran that turbo off a 5SGTE which spun past 9000rpm with significantly more boost than you can run. I'd consider that a nice match, but I think yours won't quite be. I'm prolly off on the spool calculation but you get the general idea.

Don't wanna burst your bubble, but I'd suggest you to reconsider. Maybe try the GT3082 first or downsize to a 0.63 A/R 6262.

I think you'd get well over 350rwkw on e85 with the 0.82 6262 if on dyno dynamics.

Oh no...

How much to change the turbine? Maybe a better option considering the quality of the Garrett product. Especially if cheaper. I'm sure you've read on the component differences between the two.
I do think you will notice the lag difference though. Prolly not massive, but you will notice it. Personally, would be too much trade for me, but you're not me :) haha!

If they've already done some tuning, can't you take it for a quick drive now?

Good decision Rob!
 
I also like that turbo and I've read a few articles on comparing it to a normal GT3076 through some dyno testing on an STi (http://blogperrinperformance.com/?p=263 Part 1 is linked on that page too).
 
I'm also very keen on seeing how it runs on the e85 with 20+ psi, and how it compares to your original GT3082 with the new gear (injectors, inlet mani, etc.), be able to compare the difference between the two.
 
Probably almost as excited as you haha.
 
 

good choice. ive pushed gtx3076 turbos on evos to about 330awkw on pump e85 a few times, so it should be more than enough.
I also have issue with precision turbos being oil only, its asking for trouble with the lack of airflow around the turbo on an mr2.

Here it is, GTX3076R with 0.82 A/R turbine housing:
 

 

 

 
*EDIT*: It proved to be too difficult to modify the dump pipe, so the turbine housing has been changed to a 4 bolt instead, but still 0.82 A/R.

Hey Rob,
With your brakes, did you have to change your master cylinder to accommodate for the larger disks/calipers.  If you did, what did you use?
