useually the 60-1 last maybe 5-10k miles when boosted hard. IF Jon at MDC
rebuilds it, he has access to a high end balancer, which wil help its life a lot.
Also there will be a group buy soon with a 56mm turbo wheel compressor, its
just a hair smaller, but will last longer. With a 60-1 get Jon to clip the exhaust
not only for more flow, but less turbine shaft failure.
