DOHC ZC in my 92 hatch.. http://photos.yahoo.com/slowcivichmm

Questions:

I want to rebuild my motor soon, and not sure what route to go yet all motor or turbo...

right now I have stock air box w/ aem intake arm and K&N filter, full apex i n1 exhuast, B&m fuel pressure regulator, ex tranny with new stock clutch and flywheel, comtech 4-2-1 header, msd 6al with blaster 2 coil....redline tranny fuild if that matters..lol

My plans are running a 50shot zex kit for a bit, and eventualy turbo, but I dont' know about compression...lower is better for turbo correct?? what about high compression adn turbo?

I was thinking..

D16a6 pistons
b16a rods
d16y7 or 8 stock metal head gasket forget which one it is...to raise compression

Crower cams
Crower LS valve springs
3 angle valve job
JG Cam Gears

Anything I should add??? or change??

From what I knwo this is a pretty good set up for all motor, how would it do with turbo???

 

don't think the ls springs will fit
high comp turbo is cool, as long as you can properly tune the motor, most people go with low comp turbo since its easier and cheaper to tune
Not certain with the d16y gasket i think you need to keep it in the integra realm (d16a1)

 

But aren't you better off asking in the EG forum since a '92 is an EG? some issues are different than EF's. And where some here will know you would get far better results in the group where everyone knows about it.

My guess is that the EG guys aren't as familiar with the ZC. I am also guessing that this is an OBD1 ZC. As far as the questions, the ZC stock compression is pretty good for turbo set ups. However the D16A6 pistons will lower compression. Instead of B16 rods machined to work, why not pick up a set of Eagles. Probably wouldn't be that much more and you have something you can trust. Just food for thought.

As far as the top end. I haven't ever had much luck locating after market components. Keep us updated with what you find.

True, I wans't being critical. Just trying to help make sure he got the most bang for his buck by targeting the right people. My ZC is OBD0. If I was building mine I'd go eagle rods. Have heard nothing but good for those.

 

hey jose, how's the dohc treatign you? blueck do a good job witht the tranny rebuild?

 

I'm sorry who are you?? hahaha

Yeah I guesss you know BL....me and him did the tranny works good...one bearing is making noise...other than that feels great....will open it back up in the near future for th SRR(SSR) 4.9 final drive and to change the bearings...

the car is and EG but the motor is made adn only used in EF's that is why I asked here......u know...

yes OBD1 stock.....5th aniversay edition zc sir motor...

D16a6 will lower comp?? I red that it raises compression....hmm

links to eagle rods???

Why wouldn't the d16y7/8 metal gasket work?? only stock metal gasket correct and the thinniest to rasie my comp??

insert from that thread:

Engine: Well, where the hell do we start? The motor mounts all have gaps in them. Filling them with window cement is a poor mans way to get some “solid” mounts. Okay, now that you got that sucker still, lets increase some power.
On a naturally aspirated engine there are # things you can do. 1. Up the compression. 2. Increase the displacement. And 3. Add more aggressive cams.
One way to up the compression is to mill the head. It is very important for you to not remove more than .30. If you do, you risk timing issues because the timing belt is going to be shortened and you will risk jumping teeth. You can also get thinner head gaskets, the Y8 is cheap and is the thinnest metal OEM head gasket that you can get.
Now that we have covered some inexpensive increases, lets go to pistons. The 1988-1989 D16A1 Engine came with some really high dome pistons. They cost around 30 dollars each from the Acura dealer as well, and will increase your compression ratio as follows:
d16a1 pistons (stock bore) in the following with a y8/z6 metal headgasket(no mill):
d16a6= 11.08: 1 compression
d16z6= 12.03: 1 compression
d16y8= 12.61: 1 compression
Obviously high compression and you 91 octane folks should consider a thicker headgasket.
Since you have decided to open that sucker and upgrade the pistons you should also consider upgrading your rods. Whether you decide to shot-peen your stock rods or upgrade to some LS rods, it’s up to you. Better yet, shot-peen the LS rods! When upgrading these, you should consider some ACL bearings and ARP rod bolts. Strength is always a comfort, right?
The head is what traps all of the power in any style engine. Be it naturally aspirated (N/A), nitrous injected, supercharged, turbocharged or all three. It has the valves that allow the air in and out of the combustion chamber and the cam (J) that opens and closes the valves. Porting is the process of removing material to make the holes for the valves larger to allow more air even if you use the stock cam. But, within the head you have all of these moving parts that rub against each other, even with oil there is friction. To reduce friction, you can get bronze valve guides, coated valves, and roller rockers. Roller rockers are cam followers that have wheels instead of a contact point. They greatly reduce friction and, the HX has them! Unfortunately, it only has a standard 2-lobe cam instead of a 3-lobe cam. Again another crazy topic that has been discussed a few times. Still with a custom cam, This “VTEC-E” head could theoretically produce more power than the VTEC head ever could. Since the rollers would allow for a cam lobe so aggressive that the regular followers would fail. Adjusting the cam with a cam gear can also change your power band to what best suits your driving, some drive easy, some drive hard every now and then, and some (like me) visit 7200 with every stop light and every shift. Well, almost.
Remember, an engine is an air pump, the more air it moves the stronger it is. And the best way to move air is to open the valves really high for a long time. Some good quality camshaft makers are Crower, Zex, Hondasaver, and Skunk2.
