2871R but which one

[minimivic]

I have enough credit at a turbo company for a GT2871R, but I need to know what specs are best.
Its a daily drivable Audi tt quattro (225hp version)
I'm thinking 0.86 exhaust housing but am unsure of the A/R and trims that will work best.
Searching for 2871's returned so much info, but i need to let the company know ASAP.
Thanks

From what I've read 0.86 would be laggy....

I'd narrowed it down to a .63 housing for road use.

I'm interested to see what the people that run 3071's are using housing wise. A 28 series housing .86 should be similar to a 30series .63.

on Tims GT30R he runs 0.63AR hotside, and its not bad spool and good for 450bhp
