Hey mate, i saw you were selling your turbo on facebook and was going to comme t but didnt want to f**k up your sale.. 20psi @ 5000rpm does not sound right
I use a 6466 Gen2 with .82 Vband single entry housing on my built RB26, which has a Nissan 2.6 crank and HKS 272 10.2mm cams
On E85, it makes 30psi by about 4500rpm, and makes 710rwhp
I would highly recommend this to anyone.. it has less lag than my previous 2860-5 setup, which i personally did not think was laggy.. but theres no contest when compared to a big single, it comes on like an absolute motherf**ker
