lol the AR is 'aspect ratio', not specific to a unit of measurement as such (ie inch or cm).

As for the comparison to 2835... The 2835 is nothing like your other 2 options... Its actually a 3071 with a cropped exhaust wheel.. The 2871 is something completely different.

I think you mean Area / Radius ratio

So far my RB26/30 with 272 deg/10.5mm jun cams and hks 2530's are promising and may fit your bill, time and a final tune (currently on run-in) will tell.

Standard OEM manifolds with the turbo flange ported to match the turbo.

Also split flange dump pipes (dodgy ebay ones that we had to hit with a hammer to make fit...)

and a trust front pipe, high flow cat, HKS zorst.

Genuine HKS branded 2530's with HKS wastegate actuators.

Will post up dyno charts in my main build thread when I get them.
