what would it take to make a stock 12A out of a 1980 7 after (or before if you need to do stuff to the engine while its apart) to run 15 psi safely i know i would need an intercooler but how big of one

thanx

 

Yes a big intercooler is a must and so is a turbo

 

intercooler goes with a turbo like peas and carrots!!!!!
