Need some help guys. We have a 2004 g35 with a blown engine and its a manual. We pulled a engine from a 2003 with a auto and when we went to swap over the flywheel to that engine it seems to have a extra bushing compared to the original engine. So does anyone know if the automatic engine will work in the manual car?

 

This is the bushing im talking about on the engine from the auto

 

Take things off until it looks like your old engine - I've heard on here that your swap will work but you'll need to have the correct pilot bearing and whatnot for the manual trans - don't reuse the old one.

The auto engine is obviously set up for a torque converter. Ask a mechanic if you haven't already.

 

We have taken it apart till it looks close but the auto block has that extra bushing and the manual block does not. So it stops the flywheel from bolting to the auto block
