You are now farther than I am on my wagon.
Guess I should start assembling the ZC.
Too dam many projects here and the little ones aren't helping me manage time either..
I've seen mention of a water injection kit that Jackson used to offer. Supposedly there was a plugged port in the intake plenum specifically for that use.
I can't find a picture of that anywhere . All the posts I'm finding are from'04 and earlier.
Don't port the water injection on the back of the manifold. It won't distribute evenly enough to all the cylinders. 2 & 3 will get the lion's share of the cooling and water. 1 & 4 will be starved and likely run much hotter. Put the nozzle into the air intake ahead of the throttle body. At the very least, put it after the throttle body, but before the blower. Those spinning rotors will do a great job of homogenizing the air and water, and cool the rotors and blower in the process. Don't worry about the coating on the rotors getting blasted/washed off by the water/meth. It never did it for me.
If you go between the TB and the blower, you'll need to incorporate the solenoid that I sent with the injection kit, and figure out some way of controlling it with engine management or a pressure switch. Otherwise, engine vaccuum will suck the water out of the reservoir under normal daily driving and it'll be empty when you need it most!
Thanks, Jaker. I was leaning that way, but I will have all 3 locations drilled and tapped before final installation.That way I can move the nozzle around and experiment if I want, without undue fuss.
I also picked up the header from 1981jrod to play with. It is supposed to be 2.5" collector, while the one I have now is 1 7/8"..Does anyone know where to buy just the collector flange? Or maybe just a collector tube section?
Have a read through this JRSC DC2 build, you can see how he did it with water/meth combo and how it kind-of didnt work.
An idea was to get an ~inch thick sandwich plate/intercooler made in between the manifold and the SC. A small water-to-air intercooler run through a little water pump that goes to a oil cooler radiator at the front of the car. At least with this method you can put ice or something in it if you were going to do a half hour run in 4wding. Or alternatively you could connect it up to your old aircon pump and transfer the cooler from under the dash to under the SC and use refridgeration power
Thanks for the link^^SiRge. I read for a couple days
I've been working on finishing touches to the engine. Swapped in the DSM 450cc injectors
I bought the kit with a broken vacuum nipple on the bypass diaphragm. This piece can be bought for about $90, but I'm a rigger
I used a 1/8" MPT x 5/32" hose barb adapter. Carefully drilled out the hole while holding a shopvac to retrieve the shavings, then tapped the plastic housing.
No pictures of it, but upon testing I realized that the brass nipple extended too far inside the housing, interfering with the return spring and preventing full actuation of the diaphragm. I took it back out and shortened it, then reinstalled with some adhesive on the threads for insurance.
Works perfectly. The valve cracks at 3 in.Hg
...and is fully open at just under 10 inches. It's perfectly sealed, held vacuum steady for several minutes.:)
I never was able to comprehend the instructions from the original JRSC kit about crankcase venting, so I just did it my way!
Using a section of 1/2" PCV hose, I ran from the original "black box" up through the intake runners, then along the back of the fuel rail to an OE PCV valve before dumping back into the S-pipe.
With so much going on in such a small space, it's hard to keep it uncluttered.

Moved enough junk to get 'er back inside. Here we go...
Speaking of junk- I have too much! Inside my little garage I have:
5 engines
11 transmissions
9 loose intake manifolds
7 flywheels and clutches
5 cylinder heads
etc...and that's just the Honda junk on the floor that won't fit on my shelves!
The VC will have to be repainted, I dropped it and skint it bad. I like the gold color, but the closer it gets to the pyrite the worse it clashes. I'm not sure if I'll stay with that color or not.

Anyone?
Speaking of trial and error, started modding my header to fit
Also found that a d16a6 FPR fits the jackson manifold without the angle adapter (that I don't have).
The d16z6 regulator has a straight-down fuel outlet that didn't clear the manifold.
I don't have TIG setup, and ain't paying hundreds of dollars to mod this $59 header, so what you see is what you get
other one without
The other has a Blocked off port on the back. near center of pic. After the SC
other one without
The both have different TB tube adapters.. But, Both fit d-series correctly.
I don't know why.. I think JR switched up some things along the way.
I tried google searching yesterday but all I could find were K series with jackson racing super chargers and meth.
I did at least try.
The second, newer one is what I wanted to see...I think.
Dan: Nope. Just used the regular mild steel wire. It'll either work or it won't.
RBW: thanks. You got the same results I found.

Can anyone tell im bored at work?

I paid the $90!!! Wish I had thought of this!
