Ok, I'm gonna give this a try and hope it doesn't get too complicated.

I have a 70 Chevelle Malibu that had 2 stock 87 GN turbos. One of them started to get some bad shaft play so I bought 2 new Precision TA-5557's with .63 a/r to replace them. The new turbos picked up a good bit of power and spool relatively quick but I prefer the instant boost of the stock turbos.

That being said this is what I'm looking for. Your excellent condition stock turbo with inlet bell plus $500 for one of my TA-5557's.

Your turbo must be in excellent shape and reasonable mileage. My 5557's are about 6 weeks old and have less than 800 miles on them. Each one will come with a stock ported inlet bell, and a billet inlet bell. No actuator or exhaust elbow. The turbos have been painted gray. The wastegate port was ported/blended but the hole was not enlarged.

I don't have them ready to ship but am starting to remove them from the car now.

My advise would be to go to the stock GN turbo .63 Garrett housing on them. It will cost you about $250 to get them machined and you will gain a lot of spoolup. Should be close to the stock turbos.
 
Is there a tread or page with your complete build?

I am planning a similar project for my '65 Plymouth/400ci big block and would be interested in seeing the details of your build.

Thanks,Sean
