Torque convertor vs turbo lag question

tooslow said

Thanks-I will order one. $37.00 I can't go wrong
I already have the GT-45 and it was a pretty inexpensive newby Turbo $260.00 This is kind of a science project for me. Lots to learn.
I did read a smaller turbo will spool up quicker for better low end?
Sounds like I may run out of Turbo on the top end. Putting the 383 in a truck so limited RPM

Thank you for helping!

If the 383 runs fairly well I would use a 3000- 3500 converter with a highway gear in the back ( 2.70's ), The reason is instant boost like you WILL get under the tourqe peak may make timing at low rpms a hassle ( may ping no matter what under 3000 rpm with boost ) if you tune it to run between 3500- 5000 rpm it will pull like a freight train, I imagine a gt45 China turbo would fall off at or before 5000 rpm anyway...
