I have an 1993 HCR32 with an RB20DE manual 5 speed non-turbo. I want to upgrade internals of engine and every thing around it. But keep in mind i want to keep non-turbo. What parts should i choose/need. More interested in dressing up engine inside and out. And any good mechanics specialize in rebuilding engines in Q.L.D. Around wide bay area.PLEASE HELP
