hey, i have a 93 gsr head and b18a1 block. Im wondering if i can use 97 gsr cams in this head? Would i have to get the caps machined? Would i be better off using just a full b16 head?
oh yeah, and is it true you can use a 92-95 civic si sohc ecu for this swap?


r u selling ur head or not???

all vtec cams are interchangable…so no, you don’t need to modify anything ot get the gsr cams to work in your b17a head.

yes a civic p28 ecu will work, however it will need to be chipped.

Cams will swap right in… B17 head= B16 head
same thing.
Which ECU you use, depends on what year your vehicle is.
