I know they stopped making it and it fits a d16 and a b18c. But will it fit on a b18a1/vtec?

 

B18A1 is not a VTEC engine... are you saying you have a VTEC head installed on top of a B18A1 shortblock ??? If so, what VTEC head are you using ??? GSR, ITR or B16A??? You can find used kits from time to time, so you might get lucky and get what you need.

 

I know its not a vtec motor. I believe its a gsr head but that still doesn't answer my question as to if it is compatible with my setup

 

These supercharger fitment designs were based upon the intake manifold design of the engine. So if you have a GS-R head, regardless of the block you used, then the roots blower style you would get would be for the GS-R. Now, with that said, that means that you'll need different sized pulley and accessory belts for the fitment because of the different deck height of the B18A1 Block. But if you're asking if there was ever a complete kit specifically for the LS/VTEC or B20/VTEC , as a result of high demand for creating that hybrid , the answer is no. You'd have to look in the official JRSC forum and research there to see what people did for LS/VTEC & B20/VTEC JRSC setups and what they altered in order to make it work.

Good luck to you.
