Would anyone know what the differences are between these two engines? The D16A6 is rated at 108hp and the ZC is 115 (120ps). The bore & stroke & CR are the same. I believe it may be in the ECU only. Would anyone here know?

 

The sohc zc has a different cam.

 

is everything else pretty much identical? i just purchased a zc cam and the lobes didn't look any bigger.. they actually looked smaller but i don't have the tools to take accurate measurements. It also has a weird lobe at the distributor end. wonder if that would throw off the balance of the valvetrain.

 

that extra lobe is for the mechanical fuel pump. youve got a cam from a carburated SOHC ZC. all together worth 105ps. its NOT the same as the MPFI SOHC ZC cam. the exhaust timing is a bit off. you really wouldnt be able to tell visually. you need a dial indicator to see the difference.

(whats with all these sohc ZC threads lately? a big container of junkyard SOHC engines come off the boat last month or something?)

 

so would this cam not work on my d16a6?

 

it works. i cant say if its better or not. its just different.

 

anyone else have this cam?

 

I purchased a ZC motor from hmotors and it came carb'd so I have the same cam. I switched to fuel injection and my zc will pull on other d16s w/the same mods.

 

so you started with a carb'd zc? sweet.. so i can use this cam

i am not sure if the carb'd cam will go in a d16a6. but my zc seems to pull pretty good w/ the PM6 and a little more fuel pressure. I do have the DOHC ZC tranny as well but before my old tranny died it would still pull on other d16's.

 

bump for any more input on the carbd zc cam into a d16a6.

 

the head castings are the same. it will install without issue.

 

hopefully it works out alright. I put the cam in last night while i still had the motor on the stand. It seems as though the lobes are a little bigger because i had to loosen the valve adjustment a little to get them into spec.

 

theres about a .002"-.003" variance from the A6 cam, but not much. youd have to do a valve adjustment when switching cams anyway. btw, did you consider that the exhaust timing is 5 degrees off the A6 cam when adjusting your valves?

no i did not.. hrmm.. so i should adjust the INTAKE side at TDC and then the EXHAUST side at + or - how many degrees?

 

anyone else running this cam in an A6??
