6262 twin scroll?
Any input on this turbo..I've search everywhere but I can't seem to find any s2k owner with the t4 6262 twin scroll setup..I've seen a couple of twin scroll garrett 35r setup but it's not what I'm really looking for unless I have no other option..Also, if this helps my Hp goals are 700 on race gas and mid to high 500 on pump..Somewhere around that range..lmk

you got a problem with a twinscroll Gt35??????????

Seriously though, when I made my decision to use the 6262 it was b/c the 68mm turbine on the GT3582R was a bit large. In theory the 62mm with 0.82 A/R should help the spool and transient response even more than the divided housing alone. Also they do not offer it with the Billet Wheel for it yet and they do not offer a ball bearing cartridge that does not require water cooling.

What you have to realize is the 68mm turbine wheel is measured by Garrett at the inducer of the turbine wheel (the big end). Precision measures the "62" at the small end of the wheel - the part that you can see with the housing on. If you were comparing the same measurement from PTE that Garrett uses, the "62" is actually a 72mm.
One thing to keep in mind with transient response is which bearing you decide to go with, the journal bearing units create a bit more drag and will have a larger compressor rpm delta on gear change. The ball bearing unit is definitely preferable for all aspects of transient response. (I'm not sure if you were already planning to go BB or not on your 6262)
Another thing to remember is that just because most of the Garrett BB cartridges come with a water cooling provision, that doesn't mean that you are REQUIRED to run water cooling. The oil cooling portion is obviously self-contained, so you can either plug or leave open the water cooling and it will still function fine. The water cooling is simply there if you'd like to use your coolant to pull a bit more heat out of the cartridge.

I spent a lot of time researching all the different choices and no one ever brought that up.
Is this published anywhere so I redo my reference? That really annoys me, I was looking at the 3076R but the 57mm compressor seemed light in reality it was probably the perfect size.
You correct on the bearings but the size of the wheels and mass plays are HUGE role also. Take the little T518Z on the Greddy kit, it has a much better transient response due to the small and lightweight turbine and compressor despite being a journal bearing turbo. The smaller these wheels are the better the response.
I know that many run w/o water on the cartridge but that worries me. Coking on the ball bearings has greater effects than deposits on the impeller shaft. I would be nervous using these turbo w/o out it and if I did I would defiantly want to reinvestigate a turbo timer.
Thanks for the heads up

Not with the turbo just with you.

i'm running a t4 HTA gt3582r twinscroll on my evo and this turbo is good for 700+awhp.
If you want more power they make a HTA twin scroll t4 GT2586 that is good for all most 800whp
