could i just put a b18b head on my b18a block or would that not work? would i need to upgrade to a 92 ecu? also if that dooesn't work... will the b18b block bolt to the b18a tranny?? i believe that the head is the only difference between the b18a and the b18b. if anythingelse is different that i am missing please let me know. i just cant really seem to find to many performance parts for the b18a so i want a b18b in it. thanks

 

really not trying to be mean but I just can't remember, can noobs on trial use the search function?

 

any part that u see for a b18b head will fit in the b18a head. its the same head only difference is b18b has a slighltly more agressive cams. dont even waste time or money on putting a b18b head on urs. also, searching for 2 seconds wouldve answered this question for u
