Okay, I recently purchased an Hx30 that had a good deal of shaft-play, and in separating the housings, the v-band lip on the exhaust housing side of the CHRA was chipped in several places. So I am in the market for a new CHRA. Ebay shows several aftermarket options but I have seen both good and bad posts on here about the Chinese turbos. This is to be the small turbo in my hx30/35 compound build. I am wondering where I can find a genuine holset CHRA or if anyone has had a good experience with the Chinese turbos.(as i am assuming they are Chinese). Also I have the 6cm exhaust housing and have seen multiple different diameter compressor and turbine wheels on eBay CHRAs but none match my measurements exactly. Can I go smaller and not hurt performance? Any help is greatly appreciated!
