the throttle bodys are the same size, the manifolds are different the B is slightly better flowing, as far as the cams, intake are the same no difference, exhaust the B's is slightly bigger.

 

no the a TB is smaller.

 

wow 2 mm diff 90-93 58mm 94+ is 60mm same as GSR 94+

 

so why would you say they were the same?

 

Are you planning on a swap?

 

the a is cable tranny and the b is hydro. this is if you asking about the complete swap.

 

Don't forget the pcv systems. Newer motors don't have the black box.

 

yeah plannin to do a swap not sure what yet but just wantin to know the difference befor i buy nething, was plannin on doin ls vtec but not sure...but thanks the info helped

 

the blocks are identical (pcv aside)
