take i form someone how has worked on ALOT of these maximas. it would be alot easier to get another engine and swap it out i just did one on a 91 gxe. by the time you get the engine apart and have to do heads and t-belt and seals and stuff youd have way to much caked into the car to make any moeny on it.(around 700-800) call green leaf auto recylers in tampa i got a nice low milage motor from them for my 89 se(675 with 1 year warranty) i had and it as a good runner untill the day i sold it and then some..... best of luck with the car.
