Wow, that sucks. I wish people could somehow get ahold of members on the boards who have done multiple engine swaps int their Supras and would be willing to do it for a more reasonable price. I mean, 6 months to do an engine swap? I'm with justanothervictim (sorry), 2 days (provided I had all the parts) wouldn't really be a stretch. Maybe 3 days if you wanted to replace all the gaskets/seals.
Sure members wouldn't be able to offer a 3 year unlimited mile warranty, but most members who can't do the swap themselves just want a JDM engine put back in their car so they can get it back out and enjoy it. That being said, they're probably younger, working after school, trying to make ends meet, and can't afford $1,000 for an engine and another $1000 or w/e to get it in and back to running. I know I would be more than happy to do a swap for less than half of that and, if you gave me the parts, put down 4 day MAX in writing.
But back to the story, How were the hoses hooked back up again? Trans to the oil cooler and the oil going through the rad?
