About 3 months ago I had to replace the TPH060 Pfeiffer turbo on our MAT252
with a TPH062. Pfeiffer is no longer rebuilding the TPH060 and the TPH062
is there replacement/upgrade. Not being able to find a replacement in a
reasonable amount of time I went with the replacement from Pfeiffer. I had
to wait 2 wks for a rebuilt TPH062 which cost about $2900 US. According to
Pfeiffer there aren't too many options left without upgrading the turbo
controller. Perhaps it would be good to hear from anyone who has found a
way around this problem.
