t4 hx55 turbine housing

[kelvinb]

anyone by chance know of a place that might sell these? this is pretty much the last part of my build i need and ive been looking all over the cummins/rx7 forums to no avail. ive called bullseye and they cannot do what i need. basically what im looking to do is exchange my t6 flanged turbine housing for a t4 flanged housing. if a modified hx40 housing is what i need then i can go that route. any info would be appreciated. thanks.

From my knowledge, the hx5* series turbos have neither a t4 nor t6 bolt pattern. But something VERY close to a t4. All several have had to do is widen the holes of the t4 flange on their manifold a little to get it to boltup.

Yup you have to open the holes a tad to get a HX5* to line up with your t4. i had the same problem because my 52 didn't come with a Exhaust housing. Holset is unwilling to sell just the turbine housing alone. i already tried.your best bet is to buy a core or just get another and keep one as a back up
