They are the ceramic ball bearing and oil cooled turbos. They came with .96 ex. housings but the car was flat above 5k and was overboosting. Now the car pulls hard all the way to the 7200 rev. limiter.

Can these turbo go with a bigger compressor housing and bigger compressor wheel for more volume and increased HP. What if any, choices do I have with these turbos.

Thanks for your help.

Serial # T-14229 with a 70 stamped on the inside compressor housings with 1.30 AR housing...

There aren't too many options for the 60-1 compressor wheels beyond what you have. You could rebuild the u it's and use a 62-1 compressor wheel instead. You could probaby squeeze a few more horses out of that way. There's also the GT-K61 compressor wheel now which is an updated design on the 60-1 type wheel. What is your ultimate power goal with the turbos? And what do you make now? Just trying to get a sense of your goals so I can try to help give you a sugggestion on which way to go
