Hello Everyone,

I would like to know if you can take an engine and transmission of a 2003 G35 coupe 6MT and put it in a 2006 G35 coupe 6MT without any modifications.

I thank you all for your help.

 

yup you can

 

Yeah, you can put it in, but will it work properly.
There is numerous threads about this, but before the OP takes this advice and heads into trouble.

The 2003 6MT engine is different to the 2006 6MT engine.
06 has rev up and 03 is non rev up.
