Hello. i had spoken to someone a long time ago about getting a turbo kit from you. i ended up buying a single turbo supra from wotm with a 71,fuel kit,aem,4'dp&mp,etc. i dont like the lag and want a smaller turbo that will hit high boost lower and so i dont have to put in high octane fuel all the darn time. would a 67 do the trick for me. i dont drag the car but would like it as a fast street car with minimal highway runs, just a 2nd through 4th gear car.also could i purcahse a turbo from you with dual ball bearings or does that not help out that much for spooling faster.thank you for your time.
