I'm not a fan of built motors..? Very few people know how to do it reliably.. (Motormans S13's motor = super strong) And its a rare thing to have them work for an extended period without hicups.. Josh went through a couple of built internal 4a's pretty quickly..

Mine is a fully standard 4agze with a HKS manifold (cast baby ) and a T04b turbo.. I'm running an Adaptronic with a safe tune.. Its boosting at about 12-14 pound i think.. We changed the bearings when we moved the motor to my car but it was completely unnessisary..
