You can be the mad scientist on my old ew4 head if u want it. I live in daytona beach. hows $25+ shipping sound? and its in good runing order want the cam and valves too? either way ill donate to the mad cause. hell ill give ya the ew4 block too. its just junking up my carport. email or pm either way TJ is cool with me.

I did have an idea though that you might help me with. Instead of worrying about plugging old injector holes and adding new ones, you think i could use the carb manifold to use? since the flange area of the ew5 is not as big as ew4. think i could use it on the ew4 top portion?  or perhaps i can find a pre84 cvcc 2g civic with fi and steal its manifold. just a thought

I'm not exactly sure I understand what you mean by "...the flange area of the ew5 is not as big as ew4". I thought the flange would be bigger on the ew5 manifold because it has the cvcc ports to cover. Could you explain that in more detail?

You could definitely use a stock cvcc carb and manifold because your head should be the same.

yes i see what u mean, in retropect i was talking of the surface area the intake bolted to a EW5 head not having the same area as the ew4.Which is actually less on the EW5 head, the ew4 intake actually sticks up about a centimeter from the gasket area. Which i have encoutered causes a problem because of a very slight but noticable intake leak, which may also be the cause of my stalling . The manual does say an intake leak would cause that. when i press the gas , u can notice a moment of hestiation or stalling which in low speeds would cause the stalling.

hence my whole need for the ew5 intake in the first place , LOL!!!! but i can make the ew4 work with some creativity

which ironically proves my point with what you mentioned, the carbed flange is smaller than the fuel injected manifold.

But to switch a fi to a carbed is unholy, id hate to be the first dork on rpr than actually wanted to do that. ( ohh here we go , someone will post and say i did it and then flame me for saying it)


haha ok, this is a challange but fun. hell its still drivable , just sucks when the chicks behind you are waiting for your bucket to move before the light turns yellow or red again. quite embarrassing coming off the freeway ramp after you blew by them then have them wait for your stalled car. lol

There are no civics pre 84 with fuel injection.

this is interesting...lol (got a 1.5 carb intake and carb, carb's in a few pieces though ill give it to u for a couple dollars and shipping)

Im still entertaining the idea of converting to fi if some one has all the stuff for cheap(reasonable price)... since selling my car is taking longer than i though. also i dont want to reassemble a head or ne thing

Ok, i had another idea on the way to the local junk yard. Instead of moving the whole fuel rail back an inch and messing with pluggin up the old holes. Why dont i just drill1 hole on the bacl of the top intake manifold just past the throttle body, put an integra injector there and wire splice into one of the factory injectors for the signal. that way it will feed the cvcc chambers ,all 4.and it will be down stream. I could just get a T fitting on the fuel supply line to feed it and fab up some holding device and coupling to keep from leaking fuel.

Also another idea i had to go with that is , what about that grounding wire to the thermostat housing?Maybe i could use a fluke meter to see if it has a signal from the ecu and use that for the injector wiring. The reason i thought of that is Honda most likely used the same wire harness for the US models as the JDM, and since we didnt use those wires , they grounded them.

Just some thoughts, would like some feedback and suggestions.
thnx,
Matt

or ya know...you could make a trottle body injection engine out of a DX mani

one big(maybe 2 small) injectiors for the primary and another injector for the cvcc. yeah you'd have to play with settings a bit but it is sooo doable
like eldo(? or someone else's) 4bbl carb hybrid very cool btw but i dunno about using a 750cfm on a civic LMAO
hmmmm....

I took off my intake manifold today to prep . turns out there are 5 chambers for the cvcc. *O* O**O O*. I looked at a gallery that has a ew5 manifold and only these are used *O O**O O*. so ill just plug the second one from left. I also noticed that the 5th injector is fed directly from the fuel rail but i didnt see wiring so ill have to fab up a hose/tubing to all 4 chambers and just tap holes in manifold flange to fit some fittings. should be simple. problem is which injector wire harness should i splice into? i dont think a gravity fed tube would work, being that i think the air forces it downward or at least a pressurized injector of 36 psi.

any thoughts/ideas anyone?

Iare 5 chambers for the cvcc. *O*  O**O  O*. I looked at a gallery that has a ew5 manifold and only these are used  *O    O**O  O*.

i dont get it...

hmmm i guess you dont have the luxury of a spatial mind. The O's are intake holes and the* are cvcc chambers and their location in relation to the intake holes. easier that takin pic , and fighting to get it working on here.

The extra hole is for the EGR.

well I gathered that. also I figured that the extra was for EGR but i remembered that right after i got off the stupid box. i guess the ew5 just has that disabled...
so the head isnt the same as the usdm ew1 or what??

Ive never seen the EW1 head so i dunno. but i will close that off. and just wait till i get an extra intake naifold to play with to fab it up and make it work . in the mean time , i have disabled the cvcc rockers on the cam and driving as a regular si.

ill take picks of what i had in mindwhen done. its a simple mod but takes some drilling , tapping and hose play.
