I've been using Jeff Gladish, owner of Maztech, 4810 N Clark, Tampa, FL 33614
He's been the local guru in Tampa for quite a while.
My 93 VR Base was rebuilt @ 112k
Cost: Engine w/3mm apex seals......$3,500
Turbos rebuilt by CMR Turbo...$1,175
I know we're on the opposite side of the country, but you can still get an idea on the cost.
