I had a guy come in to our shop last week looking for some glow plugs to his 3B motor. it turns out he took a 3BT manifold and a later 80s supra turbo and mounted them up and now he says its pretty quick compared to stock. I also just finished a head job on a 85 BJ60 cruiser and it over heated and when the head came off in between all the valves were cracked good and all the pre combustion chambers had taken a beating can crack also. I can get the name of the company we used for the parts ie. valve, seats, pre comb, chambers, head set. I do remember they are based out of Australlia and take 3-4 weeks for shipping though. Let me know if you need any more info im a diesel mechanic in Salinas,CA.
