Just wondering the difference between a 1995 d15b7 from a civic DX and a 1995 d15b7 from a civic CX ?

I did some reserch and some sites say CX came with 70hp and DX came with 103hp

Does anyone know what makes HP diff between these motor's

Thank's
James

 

cx 8 valves dx 16 valves

 

btw dx 93 hp

 

I pulled the valve cover and it is 16 valve and out of a 1995 civic CX

Could it be a different size cam or valve sizes?

 

no hes right cx has 8 valves

 

CX = D15B8, 8 valves, 70 hp
DX = D15B7, 16 valves, 102 hp

 

your thinking D15b2 (dpfi) which is 92hp
