I have been off the site for a couple of years because my 1993 LS400 has been running fine. Several weeks ago I was on an interstate, the water pump must have broke and I dumped all the coolant and screwed up the motor. I would like to purchase a JDM engine. I live in Florida, have a restoration shop and am capable of the engine change. What am I in for? Thanks for your reply. You have been very helpful in the past. Tom
