The FP 54 is not available from FP with BB (I asked them). But it looks like the RossSport/OwensDevelopment turbo is VERY similar and is available with BB. The downside is the price.

 

All of the new greens use the 57lb/min 73htz compressor. They offer the FP54 with the smaller turbine in the MHI housing, and they have the big 67mm turbine with the single scroll housing.

 

Interesting, I've heard of Ross Sport but yeah the price is a big downside especially with the NZ currency! @letsgetthisdone, are you using the single scroll FP red? I was thinking of purchasing one but a person told me their one was leaking oil 8months after. Also I can't find too many people fond of the SS housing?

 

Mine is ball bearing twin scroll (MHI turbine housing). Mine required crank case ventilation mods to not leak oil. But it's just fine now.
