So I've been digging through the search box on swapping out the d16 crank on my D16a1 to the D17. But can't find any hard info on swapping out the crank on a DOHC D-series. Has anyone done this to a DOHC?
the biggest problem will be with the timing belt gear on the crankshaft - most all of the D17 cranks used in the D16 blocks have been on the SOHC engines in which the D17 timing belt gear can be used (after machining off the crank trigger wheel) since it has the same number of teeth (19) as the SOHC D16 - unfortunately, the DOHC ZC (17 teeth) or the D16A1 (20 teeth) don't share the same timing belt gear that is used on the SOHC D16, and they won't fit on the D17 crank - it would need to be bored out and re-splined for the D17 crank - here is an article about the D17 crank in the SOHC D16 which goes into everything else that needs to be done:
not all the DOHC-swap setup cranks need to be shaved.
considering a B series pulley fits on the d17 crank to potentially make it a machinist-free swap, im sure one or more of the dohc crank pulleys can be found to fit.
24mm snout? im foggy on the details for sure.
but the stroker setup is worth the trouble regardless. but you do limit yourself to either stock d17 rods or only aftermarket d17 rods, and the thinner big ends tend to reduce strength, so keep her under 180whp or so lol
I've read all of the topics about DOHC ZC engine in ek civic. I found the only answer that converting it to obd-1 would work. I have a different situation.
D16Z5 is already in my ek. It has all of the engine obd-0 wiring, obd-0 dizzy. Also I have interrior wires from CRX that...
We are building a D16A9 DOHC normally aspirated engine for circuit racing in the UK.
Looking to increase the power quite substantially but there is very little information to help us !
We have two engines stripped down to scavenge for bits. We have forged pistons and con rods on order, bearings...
My name is João and I live in Portugal.
I have a D16A8 (ZC) engine running in a Rover 216 Sportcoupe and I would like to get about 200hp on it without turbo, but in Europe isn't easy to get the best material.
I want that my engine project be something like this:
I already have a...
