I bought a 1990 Acura Integra GS with a B18A1 with a Non Vtec head. And I was wondering Which Head from the B series I can swap it out with to make it Vtec. Plus I plain to swap the engine in to a 89 CRX, how much trouble would that be, and what do I need to do the swap.

Thank You!

 

b18c_ c1, c5 are the gsr and type r, then b18c3

 

DONT FOR GET THE ALMIGHTY B17A1.... 90-93 gsr 1.7 liter 170 hp..... those heads flow VERY well, but they are VERY hard to come by

 

The B17 head is no different than the obd1 and obd2 B16 head

 

Yeah, and you forgot to mention the B16.

 

yes it is.. the ports are different and so are the cams....

 

but why would you want a b16 head on a b18 block? i understand they are both basically the same block, is there anything to be gained by using a 16 head? i did not think there would be, so i kept it to the 18's....

 

If you get a B16 head, it will lower the compression. This would be good if you plan to run a forced induction set up.

 

u asked if there was much troble.. well a little ,non vtek to a v-yek takes new wiring on the ecu part and a new oil line to the head aswell..,,,

 

not from a B17 head. but yeah from most B heads it will

use a SiR head. lower compression and best flowing.
