1HD-T Engine Rebuild

Post by TWITCHIN »

Hey people. Lookin into rebuilding my 1hdt. It's done 456,000kms, have replaced the head gasket bout 2 year ago.
Just wondering if anyone has done it themselfs and what dis ya find? Also what costs were involved etc. I am a Mechanic so labour isn't an issue. Just tryin to gather any info on what people have. Also I'm not 100% sure but are these a sleeved engine or complete cast cylinder?. Was thinking about boring it out a lil bit but I haven't heard much about what are the options on these. And who did ya source the parts from. I'm not a fan of cheap rebuild kits, so where ever possible I wanna use quality parts. Let me know what ya info yas have, cheers.
