So, rebuilding a 6A13tt, for the sake of knowledge; What's involved, what usually breaks first. Are there oil issues like RB26dett's that can see piston 5 or 6 let go or spin a bearing? Any design flaws or inadequacies. Is it a biatch to rebuild a v6, more camshafts etc? or is it easier than most standard engines out there. In OZ I can't really see anyone having to face a rebuild just yet, but pays to find out all you can. What do you think would be a reasonable starting price get a workshop to hoist out and strengthen the internals of a still functioning standard engine for those chasing much higher power figures by playing with larger turbo setups like TD04's.
