Nice. Keep the updates coming
Jose

hi

Sounds great.
ilove(.)(.)

nice.
mr. honda

UPDATE: so I've been thinking of what to do next and a complete single cam ZC with trans fell into my lap (whole swap was free, got it in trade for some work). also picked front and rear camber kits in a trade. Ill post some pics of the ZC asap
4dred6

Nice ZCs rock
mr. honda

I'm going to be puting a y8 head on this ZC.... can some hook me up with a parts list plz

I posted this link, along with a complete parts list.

I'm located in South Reno, if you ever need any help on your sedan.

Your car & build is extremely similar to mine.
Whats your paint color code?

Good stuff so far pal!

thanks bud. Do you want the paint code for the red color the car is currently???
mr. honda

Just another update I now have a single cam ZC with a y8 head that I got in a trade and now it's a complete motor as I picked up a complete intake manifold and a b7 obd1 dizzy for only 60 bucks. The mani has p10 stamped on it... is this a b7 manifold? and is it a good one to use on a y8 head?

Post a pic of the mani

Paint Code for my car is R66M.... I'm going to be painting it soon though
mr. honda

UPDATE: ok so its taken sometime to get the ball rolling but the rebuild kit is in route... I got some LS meshies and I've done a rear disc conversion and I did the WD40 engine bay detail also picked up lx doors with the power windows and mirrors
89 LX SOHC ZC

Nice cant wait to see some progress.

NICE  Cool
mr. honda

Here's a before and after shot of the engine bay detail.. sorry the pics arent that great





more pics coming soon.

Car is coming along nicely! Laughing
mr. honda

Thanks guys. The rebuild kit got here yesterday so I've started on that but I work till 8pm the next few days so this rebuild might take longer than normal.

Right.... thank you I was very happy with the way it turned out I'm also using that same trick on the engine and its looking outstanding  so far Very Happy
mr. honda

Well here it is.... (sorry for the bad pic)  just finished the rebuild ill put the clutch and trans on tomorrow. Also getting the valve cover redone. Hope to be done soon
4dred6

Looks clean. Are u gonna do the VC red again?
mr. honda

no I'm going to have a friend do it crinkle black for me... he does amazing work and even oven bake's it so it won't chip or fade... I'll post before and after pics of it when is done
mr. honda

So I got bored and after some late night work......



Engine is in. I still have a little work to do but its coming along nicely Very Happy.

I'll post more pics asap also lookin to get some HX's soon
89 LX SOHC ZC

It always feels good to get some work done nice progress man.
4dred6

Awesome  Very Happy
mr. honda

UPDATE: engine is in and it cranks, has spark, has fuel and timing is prefect but it just won't fire up......
EF Sedan Enthusiast

Double and triple check your grounds.
4dred6

Check ecu if it turns on when u turn the key on.

Check the firing order on the spark plug cables.

Like Jon said check the grounds.

Fuses?

Does the main relay clicks when you turn on the key?
mr. honda

Ecu does turn on but the CEL stays on with the p28 and with the pm6 the CEL comes on for 2 seconds and then clicks off

all the grounds and hooked up and I can't see any signs of corrosion

main relay clicks and all fuses are good

firing order is correct 1-3-4-2.... 1 being the left bottom corner if looking strait at it and moving in a clockwise direction

I think I need to test the dizzy I think the coil or igniter unit maybe the cause

That doesn't sound right... Let me find a pic you can reference from

Stupid picture, but this is how it should be:

4dred6

Yup firing order sounds right. Dizzy 180 Degree off maybe??
mr. honda

4dred6 wrote:

tried that to and it would only go into the back of the cam oneway
4dred6

yea is rare when the dizzy goes in both ways but you never know.

did it ran before, like already converted to mpfi.?
mr. honda

Yes I rebuilt the sock motor in july and converted it to mpfi at the same time and it run after the rebuld before I pulled it for the zc swap
4dred6

That's weird idk what else could it be

I didn't realise my dohc zc had a different firing order! Sorry mate.
mr. honda

@ Sp33- no worries bud I was starting to question it myself though.

I think I'm going to check the voltage to the injectors I was thinking last night that just because fuel is passing though the fuel rail doesn't mean the injectors are working

mr. honda wrote:

There you go, try using starting fluid. Open the throttle body and spray
Some in it, you'll instantly know if it's the injectors.  If it tries to start
then focus on the injectors
bac_ed36

Looks like your in a tight spot. Go with the injectors it looks to be the problem. Or switch out ecu's.

will do... I've a p28, pm6, and a pr3 with no change
mr. honda

So I've got zero compression in cylinder 1 and 90 in cylinder 2..... I didn't bother testing the other two cylinders..... and I'm not sure but only three valves in each cylinder are moving. is this a sohc vtec thing?
4dred6

No, all 4 valves should open and close.but don't trust the compression
test just yet. Cuz to my understanding the motor should be warm to
perform that test, I'm I wrong, other thing you can do is poor a bit of
oil into the cylinder so it can seal.
FlatTireRacer

Ok *cracks knuckles*, first question: are you rolling the engine over to where each cylinder when you test it is at TDC for that individual cylinder? The way to check for this is to watch the cam lobes. Both the exhaust and intake lobes will be "up". While 4dred6 has a good idea for the oil it should be a thinner solution. Something like Automatic Transmission Fluid & Mineral Spirits mixed 5:1 will work great. The reason you need something thinner is because you don't want the thickness of the oil to seal up small holes that will return when you fire the motor back up. Compression tests are better performed warm but they can be done cold too. You just have to take that into consideration when receiving your final numbers. Second question: When your making your assessment, how many times are you turning the motor to build up pressure? Should be at least two to three times for each cylinder. Turning it over by hand is acceptable but if your doing it in the car put the starter to work for you.

Now with this being said, I'm not trying to call you out as an idiot or anything I just don't know your knowledge of motor workings. Ok? So if you're reading any of this and being like "No s#!t...?" Don't take it personal. Lol! Hope some of that helps, bro!

Also there are two different VTEC cams profiles for the SOHC VTEC head. One, when VTEC isn't engaged opens both intake valves but only about half what they open when VTEC is engaged. The other does open one intake valve almost all the way full time and the one next to it just a fraction of that. When VTEC engages it opens both intakes all the way. Unfortunately I don't know which is which anymore. Sorry.

When I test compression I use the starter to crank the motor for me and I crank it until the needle on my gauge stops moving. oh and I welcome constructive criticism it helps to hone our skills as mechanics. I'm going to try sealing the cylinder and retest
mr. honda

SHE LIVES......... HAHAHAHAHAHA. After doing the compression test and little more troubleshooting I went with my first instinct and changed out the whole cylinder head and it fired right up. Also now the oil light is on bit there's plenty of oil in it I'm thinking that maybe because I havent hooked up the vtec wires to the ecu yet is why its on
4dred6

nice. and about the light, oil pressure sensor??
mr. honda

maybe I'll be troubleshooting it later on today
89civicracer

Glad to hear it cranked up...
mr. honda

me to and because the muffler fell off (before I got the car) its sounds really cool....... NOT. But I'll upgrade the exhaust at a later date right now other than the engine I'm working on adding power windows,locks, and  mirrors
89 LX SOHC ZC

Good to hear she fired.
mr. honda

Ok so I fixed the oil light issue but now the seems to be very low fuel pressure.... I'm starting to get frustrated with this swap but such is life I guess...... anyway fuel pump primes for two seconds and the main relay clicks but when the I loosen the bleeder screw on the fuel filter (because I don't have a pressure gauge) the fuel just leaked out when the key was turned to the on position it didn't spray.... could this be a filter problem?
mr. honda

Ok so I got it running again the problem was I wasn't getting any spark though the plugs in the engine a quick change out and she fired up with no issues Very Happy.

Here's how she looks right now

Looking good homie
