its time to upgrade the super B. looking at a

killer B 63/65/14
a 62/65/14
and a 63 or 4/68/14

the truck is and alway will be used as a truck but i pretty peppy one. will always b a single turbo, possibly an occasional pull at the fair. 500hp range. im really leaning toward the bigger turbine wheel but like the spool of the 65. any first hand experience with any of these maybe price differences.
thanks

 

at 500hp i'd go with the 68 turbine we've been using them alot latly and i really like them. they spool very close to the 65. as far as price its just $50 more for the 63/68 vs the 62/65

 

also what is a relitivly safe PSI # to run with the 62 or 63mm wheel with stock bolts and HG? seems everyone likes the 35-40 range but there has to be a large volume difference between a stocker and one of these.

 

i wouldnt want to push it past 40 without studs
