it's only in the shop all the time because you got the cheapest or didn't use your head. think cautious. if the stock motor can run 12psi all day long for years with no problem then run 10-12 but no more. if you want your motor to handle 20psi don't build it to handle 22psi build it to 30+. use a boost controller with limiters ( blitz sbc id-lll ). use an engine management system that will cut your rpms if boost is above a certain point (hondata). use ebay to get the lowest ( not cheapest ) price on the best products for example tial 38mm wastegate for $180 brand new or hks ssqv bov $130.

again tune the car right, use reliable parts, leave a wide margin for safety, know everything you can about what the parts are suppossed to do and remember an ounce of prevention is worth... not havng having to say your car in the fucking shop AGAIN.
