How many people out there have a SOHC ZC? I have one in my 88 CRX Si and it pulls hard as hell. What modifications have you guys done?

i have one and yes it makes good power for the 1.6 non vtec.

i did have a sohc zc and it ran pretty nice. lot better than stock engine. i ran a 50 shot nitrous and ran 14.7 at like 93 i think. but now ive upgraded to dohc zc and turbo just wish i could get it running right.

im in the process of building mine but im doing a z6 head and a sc50 turbo with forged internals and built topend.

Ive been pretty happy with mine, basic bolt-ons, it went 15.1@90 with the stock dx 13"s at gainsville

I have a couple of questions sorry if this is the wrong thread.
I am getting a crx si with a blown motor for a daily driver. I am between a stock d16a6 and a sohc zc. so heres the question is there a huge difference? and i know its pretty much pluyg and play for either motor but do i need a different ecu for both '
thanks foir any help

Gumbey75

my friend with a 88 a6 has the basic bolt-ons and higher commpression pistions. im only stock with DIY cold air and i can spank him around about 1-2 cars ahead

The SI ECU will work fine with both. I think the only major difference between the D16a6 and the SOHC ZC is that the ZC has a more agressive cam.

so i couild put a zc cam in a a6 and have the same thing? or would you go to HMO and get a z6 swap?
i should add i may boost it some day with a t25 or something

CRXSiSage

Well, i wish i had a zc...All i have right now is a big ol' d15b2, and im thinkin of the mini-me.

I have a SOHC ZC as well and I think the main reason is its pretty inexpensive and easy to do. I'm hoping to turbo mine pretty soon as well.

I have the SOHC ZC cam in my D15B1 head. The profile is much more agressive than the original (an extra 3 or 4 mm height on each lobe). Pair that with an MPFI swap and you pretty much have a SOHC ZC. With the cams being interchangable you can see that there probably isn't much of a difference between a D16A6 and the JDM SOHC ZC.

1_Slo_zc

so save the money and find a good d16a6 or go sohc zc swap? That is my real issue and wanted to know if the power/reliability was worth the money, and the ability to turbo the motor on all stock internals.

Idiotboy

Im getting a SOHC ZC from HMO, and I plan on putting a T25 turbo on it. In theory it should make 150 to 160 HP, and thats alot in a CRX or Hatch. Plus its like $160 cheaper than the DOHC ZC and its only a factory 10HP difference between the two. For bang for your buck, its the SOHC ZC all the way.


By the way kool thread, nice to have some SOHC D sreries disscusion.

Were you able to just use the zc cam gear when you put that in? I really want to get rid of that d15b1 "fuel efficent" cam

1_Slo_zc

at the risk of looking like a fool i am going to ask a stupid stupid ?
What is the engine code for a sohc zc. I have a problem with thinking i know what im talking anbout when i really dont. I know a d16a6 is a stock si and a z6 is a sohc vtec what is the non-v ZC?

Ass$nyper

motor code is ZC
i dont get why but every sohc ZC I've ever seen burns oil like a **** was it due to the headgasket being differnt the a6?

Idiotboy

Hey question, can I use D16a6 pistons in a SOHC ZC, I want to get forged pistons and rods before I slap the turbo on?

i had a sohc in both of my crx's. 88 and 89. my best time was 15.64 @ 88 i believe w/a ghetto intake and exhaust. i think my car weighed 2900 lbs too. (i lived out of my car so all my **** was in there)

c.dub

I got a sohc zc in my 89 crx. I'm putting on a p&p and milled Y8 head very soon

Can us D15 guys get some feedback from sohc ZC cammed D15s? I'm really interested in this thing.

I got a sohc zc in my DA teg went well with i/e went a bit better with a custom turbo kit 250whp stock engine.

I got my SOHC ZC cam off of ebay. It dropped right into my D15B1. This was the first mod I did to my engine and even with the DPFI there was a noticable difference. I did my MPFI swap and an intake and my engine sounds sweet. Unfortunately I never had access to a dyno so I can't give any real numbers. But if you're looking for a few extra horse than pick up a zc cam. I know that the lift on the ZC cam is definitely higher than the D16A6 cam.
