Best Exhaust housing size for BHT3B bottom turbo.

Postby MikeThomas » Tue Apr 01, 2008 12:28 am

Just educating my self, but what would be a better choice for the exhaust housing on a BHT3B, the 26 or 23cm housing? My top turbo would be my 60/14cm setup... How does those number equate into a/r numbers?

Go with the 26 if you aim to be pushing much fuel. Like 400+rwhp worth.

Mike, if you get one with a 26, and you want to try a 23, guess what I have hiding in a box in the shop.
