I am looking at making it more for a 1/4 mile. I don't pull very many loads other then a 4 wheeler. As for budget don't really matter just list some things and ill work on getting them. I hear the GM-8 spools faster but it will choke as the ATT will take longer to spool but won't choke.
What would be a good turbo to replace the GM-4 turbo? I am looking at a A-Team turbo. Id also like to know whats the max boost I should run. I hear 12-15 is the max and stock is 7-8. Id like to know a few things that will improve performance. The few things I have is a 4" Exhaust and Air pod...
