im replacing my d15b2 head with a d16a6 head. the a6 has about 150 less k on it, and a more agrressive cam so it'll be good to have. i want to put the head on my block. keeping the DPFI (if that matters) not converting to MPFI. i just want to know if the timing is the same and if it isnt how do i adjust is and by wut specs? thanks guys. one more thing... im replacing the gasket. i buy an a6 head gasket correct?

 

bump.

 

I have done this my self before and it works fine. If I remember correct the b2 and a6 heads are from the same casting just with a different cam(dont quote me) I used the head gasket for a b2, but the box says b2,b1,a6 etc.

 

in order to use the a6 cam gear in a b2 head u have to have either a y7 gear or adjustable cam gear, their 4.5 degrees diffrent..theres a small diffrence with the cam and DPFI, but not as much as u would see with MPFI

HEAD Castings where Honda was lazy and used the same mold
D15B1
D15B2
D15B7
D16A6

If you can, use a head gasket from a D16Z6 or D16Y8 (Same thing but one may be more expensive then the other), not for the compression increase but for the "I'm a metal head gasket and won't leave a hell of a mess like my paper counterparts."

 

so putting my a6 head onto my b2 bottom would be a direct plug n play swap then? really dont wanna expletive things up lol. i tought the same was the only real difference, just wanted to make sure the timing was the same between the b2 bototm end and a6 head. thank for hte help

 

If you want to specify timing, there is a 4.5 degree timing difference between the B2 cam and the A6 cam.

 

I would definately get the (d16z6)metal gasket over the stock paper version..And for timing issue you can get an adjustable cam gear..

Is it 4.5 degrees retarded or advanced?

 

im not swtching just the cam... the whole head...or do i still have to adjust the cam? or is it not necessary to adjust it?

AEm good **** i would assume.. or is spending this much money neccessary?

do i just put this ontot he cam and instlala nd its good to go?

 

I recomend megan racing cam gear(s)..Ive used megan,older aem,and skunk2 and the megan was the best in my opinion..

about a year ago i swapped the A6 cam into my B2 engine, and had it pretty figured out so i didn't have to use an adjustable gear, but if you want it perfect you need one.
