That's great feedback. Thanks for your input on the different tranny's. I have never been a big fan of V8's. My background is in the 4 and 6 cylander Nissan Engines. I love an I6 turbo engine!!! That's why I really would love to do the 1JZ. So, according to what you are saying, the SC300 is by far the better choice over the 400 for what I want to accomplish. Thanks very much for your reply. I will have to decide whether I want V8 power or to find an SC300.

I have searched every thread I could find at this and other Lexus and Toyota web forums and have not found a difinitive answer. I am considering purchasing a high mile SC400. It has over 180K and I know that the engine would last another 100K,... but not at boost. I would like to swap in a low mile (50K) 1JZ engine set. I assume that the mounts are the same? I know that most car makes with two or more engines choices in the same chassis are setup with the same mounts to make the manufacturing easier. Is this true with the SC's? I assume that the tranny is the same length between the 300 and the 400, because the shift lever is the same place in the two cars. But, what about the driveshaft? Is there a difference between the rear diff in the two vehicles? Do I need to get a custom driveshaft to mate the 1JZ tranny with the 400 pumpkin? Wiring will be a pain in the neck.. I know that ahead of time. Are there any wire diagrams that anyone can post a link to? Yeah... I could make things easier and just get a SC300, but they are a more expensive to purchase than the 400's. Any input would be greatly appreciated. Thanks EIKON
