do i have to change the intake manifold? or it dsnt clear the hood?

 

Most folks replace the B20B I/M for one out of an LS (B18B1). Also, you will need the correct intermediate shaft along with the 5spd rear motor mount. Yes, both of these parts are different compared to the automatic ones.

 

any specific reason why they change it??

 

it doesn't clear the hood.

 

oh ok thanks
