So I went for a autoX'ing event, after the finish of the first go the turbo bearing went.
I have a new CHRA that i'm testing from "Turbo Rebuild Limited" as their standard 270 degree bearing variant, as they offer an uprated 360 degree one as well specifically for the GTIR.
When I took the old one apart two things happened, one the housing had multiple cracks tracing around the CHRA turbine housing seal ring and interior, and the housing is a 0.64A/R. The turbo that was in there is not standard and I believe it's from a S15 T28 turbo (as its PN 14411-91F00 suggests).
The CHRA I received was meant for a GTIR and wouldn't fit the with the turbine housing I had on hand, so I bought a genuine garrett T25 turbine housing with a 0.86A/R IWG.
However I just tried assembling it back together and find it also is not the right size. The CHRA turbine side flange is much smaller than that of the turbine housing I have and the trim must not be the same as the turbine will not clear the housing completely ( though it is very close)
Can anyone point me in the direction of what specific housing I need??
I've attached some pictures to show the difference in the OD of the CHRA turbine size and the ID of the Housings' flange for reference
TIA
