Anyone know where I can find the spec's on the 99 turbos from 3rd gen? Or any site that tell u what blade andbearing was used in the turbos? I want to make my 93 turbos into the 99 spec's, thanks

 

Thats not really feasible. One of the main advantages of the '99 is the abradable seal which results in a much higher efficiency. On the 99's, each turbo is 1mm smaller and reshaped. Without the 'trick' seal, you'll only be making turbos that possibly spool a little faster while producing less power over the stock setup(not to mention modifying the internal housings to compensate)

Better off just saving time and money and getting the '99's
