68hta a big turbo lol. Matt your a funny guy
My 68hta is flowing 52.5 lbs a min, and I think any turbo under 55 to 60 lbs/min is small
I am just advising if you are going to do all the work to swap the turbo your better off getting the 68HTA there price is relay low right now.
you can just set the boost lower with a better turbo to get better results and you will be happy down the road when it's time to turn the boost up to 30 psi or more =).
