I'm new the game GN here, so bear with me...
I'm doing a complete engine rebuild on the '87 I just purchased, and while tearing it down i discovered the turbo has a ton of endplay (so much that it's digging into the housing on the intake side). When I purchased the car the previous owner told me the car had recently had a new turbo installed (about 5,000 miles ago). The model number on the housing tag reads: TRO448.
First, can you tell if this is a stock turbo from this tag?
Is there anyway the turbo can be shimmed to remove the endplay? (I realize I will have to clean up the inside of the housing and replace the rotor if this is done)
If it is necessary to replace the turbo, what would you recomend for a replacement, and any suggestions for vendors? (I want to keep a fairly stock appearance, and i would like to upgrade. Currently i've got a stock converter, but i'll probably be upgrading this winter. I'm installing a mildly larger than stock cam)
I also found the car has a cracked head and have decided to upgrade rather than have it welded. Any suggestions for a ported iron head? (I'm looking at champions)
Any thing else you would suggest to have done while I've got everything torn down? Other than gauges, an aftermarket fuel pump, and K&N filter i't pretty stock right now.
thanks,
