OK, I just purchased 2 3rd gen preludes both 90' red ALB Si's. I made a pretty decent Lude out of the 2 but now need an engine. 1 car is 5-speed the other an auto, the "good" is an auto and that the one I want to put an engine in. The 5-speed has a B20a in it that has 250k miles on it but runs. The Auto has a B21 and doesn't run. I searched but alot of the links given are now dead. Does anyone have a lead on a B20a5 from a JDM importer for a decent price. The best deal I can find is $725 shipped from noyanusa. Nippon-motors sells em for $495 then $200 shipping but are out of stock. Anyone have any ideas???? Thanks.....
