will a DOHC ZC head fit on my D16A1?
i got the dohc zc rebuilt head with JG engine dynamics
the zc came from nippon motorsports some time ago.
i paid 50$ for the engine and it needs new rings im guessing
and the main piexe to hold the crank in so i was wondering i i could just swap the rebuilt head onto the d16a1

 

the DOHC ZC head will bolt right onto the D16A1 - if the A1 is 86-87, the 88-91 ZC head will have different bolt patterns for the distributor and for the cylinder sensor - if the A1 is 88-89, the ZC head will have the same bolt patterns as the A1 - the ZC head has different mounting hole locations for the timing belt cover - the ZC head has a hole on the end for the driver's side engine mount that the A1 doesn't have

 

i have a 89 d16a1.
so the head will bolt on and i can use the camgears.
will it make any power gains?

the A1 head uses one head bolt that is longer than the other 9 - the ZC uses all 10 bolts of the same length

 

so really it would be pointless? ive head the ZC cams are a little bit different. add a little more hp

 

the ZC cams are better than the A1 cams - just use the ZC cams in the A1

 

yeah i could do that. and change out the crank gear so i can run the brand new camgears

 

before you tear into it to change the crank gear, make sure that both cranks have the same size front snout (where the pulley and crank gear go on) - both the ZC and the A1 came with 2 different size front snouts, one was 22mm and the other was 24mm

 

how would i go by doing that?
