I was getting usually 17-18psi boost causing my truck was not perform while towing load at highway speeds like it used to. During my turbo "rebuild" I was hoping I would find an issue with the ring or vanes but was my turbo was in clean condition and no significant wear on anything including the ring and vanes. I replaced all the kit parts including the compressor housing o-ring but this did not improve my low boost. I have since then pressured up my induction and exhaust tracks and I discovered a significant pressure air leak in the compressor housing, and maybe this was the issue all along. So, finally my question. Can the compressor housing be re-machined?, would this be a good idea? which turbo would you recommend if I need a replacement? My truck has no tuner and is pretty much stock except for some durability mods. As far as the replacement turbo I don’t necessarily want a performance up-grade but a durability up grade would be good.
