I got it rebuilt because of the bad rings it had. i rebuilt it with arias pistons and eagle rods, other than that just normal stuff like arp head studs, new oil pump, new rocker arms and 5 angle valve job stuff like that. i've pretty much left the head alone for now, there really won't be a need to touch it until i put more boost on it later this year. i'm only gonna run 10psi for now, which will still be a GOOD improvement over stock SR, but i'm waiting to buy injectors, map ecu, and do the head work all at the same time. the place i had it done is Paradise Racing
