I think they're close enough, but still wish they did a .64 hotside 7163. We're really a niche for BW though with our relatively unique turbo location. On my inline 4's with very short runners there's very little difference in spool time between the two. When you've got 3 feet of piping it is more pronounced though.

Not really comparable since it's the B2 frame vs the B1 so the hotsides and wheel aero are different. The data I saw on the 7064 put it slower spooling than the 7163 with roughly the same output. The steps are really 6758, 7163, 7670.

I know the 7163 came out after the 7064, but I have no reason why anyone would want it over the 7163. Personally

In my case, the 7064 is a better match over the 7163 for my S2000.

To the guys running 7163s at high boost: are you using the stiffer spring in the EFR bpv?

honestly it has a bigger inlet so you dont need as big of an ar to compensate for the lack of exhaust flow

I didn't, ran the oem one with no issues up to 27 psi. I swapped to a Forge unit later
