Turbonetics Rebuild or CHRA Swap?
My little brother's Turbonetics 60-1 took a crap. He thinks he needs an exhaust wheel, the shaft, and new bearings and seals. Evidently the Turbonetics stage 3 wheels (with larger 5/16 shaft) have been discontinued and replaced with F-1 wheels, which will not work with his exhaust housing. So he has been told he can either replace the exhaust housing and update everything to F-1 spec, which would supposedly cost him 7-800$, or he could upgrade the center section to a BB Garrett T-series CHRA for about $900.
Is there any reason he should or shouldn't do either of the above? Which would you recommend?
