any advantage off putting a vf28 exhaust housing on to a vf35, or leave the vf35 as is.

silent running

Dunno. Is the VF28 exhaust housing bigger? If so, surely you want to do things the other way around...a relatively larger compressor housing with the standard exhaust? Otherwise you're generating greater turbine efficiency at higher revs with the classic trade off of worse lag...but the standard compressor wheel will be 'overdriven' beyond its efficient range by the turbine. So in effect, you get the WORST of both worlds - more lag, and inefficient compressor flow when it actually does get working? But I'm not an expert but that's how I see it. I may well be wrong.

Anyway, this link might help. http://www.mrtrally.com.au/forums/to...TOPIC_ID=25267
