Who runs a GTX3071 then?

[Rocco]

I have that turbo rocco but with .82 tial housing as its better for spool up I have been told mind you your a stroker would like to see your power band

and how do you describe it?=

are you running it on stroker?

I'm not on a stroker rocco just a 2.2 with oversized pistons. When are you mapping? Would like to see that's all

I have now CT355 turbo and tubular manifold but i thinking to change this to wagner rs2 evo t3 manifold and new turbo what i compared are garrett gtx3071r or Borg warner EFR-7670. My engine have ported cylinder head.
New setup must give about 500-550HP.

Can anybody advice good distributor for Borg Warner turbochargers in Europe ?

Crag at Tdi Turbos quoted me a good price on an efr. For your power goal a 7163 will work great.

01202 825650 ask for Craig.

Sorry got confused with jarnos post looking 500 to 550bhp efr 7163 is perfect for that.

Thanks!
Regarding power target I'm looking to more or less the same; ~600bhp (2.5 stroker) and looking into twin-scroll EFR-7670 (1.05 A/R), but I'm still afraid if it will not be too small

[diesel des]

7670 should do that. Same target as I have on my urq stroker. I'm using a gt35r with 84mm billet wheel.

No point in a twin scroll on our engines unless you plan on a quick spool valve

Yep, I was just wondering how the twin scroll would work.
the QSV will hopefully help with the bigger turbos. Has any one use this on their cars and can offer some insight on how well they work.
