going h22 on boost built block ad head with a blockguard tryna make around 500 or 550 on a street car looking at precision turbos anyone got any idea what size is best

 

Is that power requirement on Pump or race gas? You've been PM'd

 

6262sp from precision has proven to be a great all around turbo

 

idk the 6262 goes on track cars and on a pump gas street car wouldnt that take too long to spool and causr me to have trubo lag. i know guys with track cars that have his turbo they claim its too mych for a street car

 

just put a squirl fan on your intake manifold, hook it up through your 12v cig lighter and feel your power bands kick in....

 

As I stated in my PM to you, you need to state some goals, purpose, engine, chassis, budget (amount you're willing to spend on the turbo) etc. Precision is a good company to use, but there are also other options
