Hey guys im kinda new to site and engine modding but this question is .....Will a d16a6 haed fit and function properly with all other components added on a d15b2 block? I ask this only because i have a chance to get a d16a6 head and IM ,dizzzy, and other stuff for free ......and my duel ponit setup aint cutting it .....just in case you dont know by engine size my car is a 90 ED hatch wit the d15b2 engine, the valves are shot it smokes like crazy when i floor it. but the car is not bad for $50. car........any info is appreciated

the a6 head will work. you of course need to mpfi swap the car, but other than that, it should bolt up and work.

mass-hatch

yea the mpfi is what im going for just could not find any body talking about all i find are d16z6 and y8 swaps ......but thanks for the info

It's bascially the same head, everything will bolt right up.

that d16a6 is out of a crx si or hatch si right ? so si harness and what a pm6 ecu should work? right

sanimalp

yes. si crx or hatch.. pm6 will run it.. you will need the si distributor also.

the wiring is really the hardest part.. but there is plenty about that in the faq.

when you say the wireing is the hard part ;do i need the other half of the harness that goes into the car to the ecu.or can use the dpfi one to my ecu?

whoa its len 2

d16a6 head will bolt on. if you use the d16a6 cam, use a y7/y8 cam gear. if you use the d15b2 cam, use the d15b2 cam gear. as far as wiring, use your dpfi harness and convert it to mpfi. theres lots of write ups on this site on how to convert it.

sanimalp

That is correct.. you keep your entire wiring harness from your current car, and add a couple wires to handle 4 injectors instead of 2, and the additional sensor on the new si distributor. you also need to do some pin swaps in the connector in the cab of the car so all the wires go to the right ecu pin now that you are using the pm6 instead of the pm5.

Search dpfi-mpfi or just look in the faq.. there are probably atleast 5 different tutorials on this site that all explain how to do the wiring portion.

Or you can sent the whole harness to rywire and he will take care of it for you, for a price.

thanks guys for all the help..... i was worried about the harness part

ok so y7 or y8 cam gear...now do i still use the d15b2 timing belt ?cause i am using the d16a6 head with cam....and what years do i get the y7/y8 cam gear from?is it 92-95 ?

whoa its len 2

d16y7 and d16y8 share the same cam gear. theyre found in 96-00 civics. use the d15b2 timing belt. reason for doing this is because the y7/y8 cam gear corrects the timing due to the difference in deck height between the a6 and b2 blocks. the dealership sells the y7/y8 cam gear for under $20 bucks.

thanks for the info

i know this is old but i figured i wou add info here rather than start another, dead end thread.

why cant i use the b2 cam gear? on the a6 cam?
