Just incase someone is in need; I just picked up my service kit for my TD04HL-15G turbo and have to say that i'm pleased with the kit.
I have rebuilt a few turbos with aftermarket service kits for $80-$120 and never new what i was missing. I picked up a Mitsubishi kit this time for $150 and was amazed at how thorough the kit is. Every serviceable part, save the turbine shaft is included. Imo, buy the OE kit.
I can't recommend Alamo Industries in calgary here enough for turbo rebuilds or parts.
