I just bought my 88 CRX yesterday and it already has a SOHC ZC swapped in it. I was wondering if I could use the D15B VTEC head to build a mini-me. I have tried to search for a good write up but I am stumped. Thanks in advance

 

Sorry I was wrong,,I dont know ****

actually, there are 3 D15B SOHC VTEC engines - one has head like Z6 - one has head like VX and one has 3-stage VTEC

I thought all the d15b vtec engines were 3-stage vtec. Because if they were different, they would make different power numbers. Thats why the d16y5 makes 10 hp less than the y8, because of the 3-stage vtec

i jdm d15b vtec has a more agressive camshaft compared to the zex 55410 camshaft

read my post in this thread maybe it will help you

and they a;; arent 3 stage, only the ones that came from the ek's were. the generation that you will find the most came from the eg and those only have the regular vtec stage.

and yea the cam in the d15b is more agressive than the one in the d16z6 and is comparable to the zex cam.
