TW: Distributor adaptor plate GB?

[Secondaries]

I've been trying to figure out for a while how I wanted to install the F22 distributor for my OBD1 conversion. I want to keep the engine capable of being reverted back to stock, so I've settled on the idea of an adaptor plate. Using the eMachineShop software, I drew up a sketch of this plate with rough estimate measurements, but a one off plate is expensive - eMachineShop quotes me $219 for a single plate. But that price drops off DRASTICALLY when the number goes up. For 10 plates, the price is $55.25. For 50, it goes to $42.51 each. For 100, the price is $29.56!!

The piece I've designed is in 4140 Steel. I originally tried to get them to quote me in 6061 Aluminum, but the program told me that the material wasn't suitable for the machining that was asked of it (specifically, threading).

I'm including an image to give you an idea, but please note: This is without any real measurements taken. I'll measure the exact hole dimensions for the head and clock the F22 dizzy mount holes to just the right angle, but this is a simple quick n' dirty to get a quote. The price shouldn't change when I correct the measurements.

I just wanted to gauge interest in a group buy on these. I don't want to spend $220 on this plate, and I'd like everyone to get in on it also. If nobody's interested, I think I'll just buy a mini drillpress and make my own. But if you are, I can take this drawing to a few local shops to get quotes. If they are about as much as eMachineShop, I can just go through them for simplicity's sake. Please, let me know guys. I guess I'll throw a poll up there.

Also, I'll draw up a cam key spacer also, and that'll probably cost a few bucks more, but before I go through the trouble, let's see who is going to be seriously interested.



EDIT: Oh yes. Please don't view my 38 post count as belonging to some guy trying to scam you guys. I've got over 1,900 posts on PreludePower. I've been a member there for 5 years now, and to alleviate any kind of fear, I'm going to put my info right out there.

If this goes through and I flake out, I want EVERYONE close to me to come and beat the crap out of me! But that is NOT going to happen.

[ghettogeddy]

im def interested

[MessyHonda]

cool i would get one also...but the plate would not help alot you will still need to grind part of the distributor so it can clear the water pipe behind it.

better then cutting the ears off and we welding them lol

i dont think 10 people would do it also....you would need to have at least 500 bucks to do this swap. i got my parts cheap but here is a break down.

stock 4th gen distributor if bought new or reman ~185
conversion harness~110
ECU~150-200
adapter plate if 10 people buy~60 bucks shipped.
Dyno tunning~100bucks per hour plus tunner (may take up to 2-3 hours)

at the price some of the current obd 1 users might want one for a cleaner look and it like 60 bucks thats nothing lol

my swap looks every OEM. i have a high chance of passing visual on my car.

we only have 4 running OBD1 swaps on A20s nation wide that i know of

Guayanabo

maybe some one else

most of the turno guys are obd 1 arent they or are they stand alone

[MessyHonda]

i dont want to F* post whore...but damn geddy...only guy one stand alone is some guy over at prelude power that has a 2nd gen cyruris or something like that. 87 prelude still had a vac advance dizzy, bobafet has been taking his time doing the obd1 or stand alone option. Eliah( i dont remember what he was running but im prety sure it was not obd1 but i could be wrong) a20a3 just has a turbo manifold...im not sure what management accordentepricer(sp?) is running im sure johnny O and jason bud had stand alone on the car.

[ghettogeddy]

well that adds a possible 4 people lol
and u dont want to post whore lol thats a first

4?

[ghettogeddy]

4?

whatever im interested anyone else

[bobafett]

another thing you guys might want to look into is designing this adapter plate, and having somebody like aaron weir build them for us. I am not sure if he would even do it, but it might be cheaper than e-machineshop pricing, and more we probably wouldn't need more than 10 to get him started with it.

food for thought anyway, this is his email: [email protected]

I think this is an awesome idea!

[Chuoiz]

I'm interested...I like simplicity..

[2drSE-i]

im interested, but id need the cam key along with it. It would also be necessary to make a spacer in between the cam end and distributor end.

[bobafett]

and by creating a cam end spacer you could build the offset angle into the spacer, so that you wouldn't need to re-index the key. that would be a much more elegant solution imo...

that actually makes a lot of sense. The 4g distributor key is 90 degrees off of ours right? i also had a question about timing, i think someone in here could answer me. 3g distributor should be adjusted to 15 degrees BTDC, where as the 4g should be adjusted to 4 degrees BTDC. What would we adjust it to, 4g specs or 3g specs?

[Secondaries]

From what I understand, it can be mounted so it isn't off. But I will figure out how best to mount it, angle wise, and I'll draw up the cam key spacer to account for any rotational difference. No modifications whatsoever will have to be performed! Just bolt up and tune!

yup....i know openloop had made a custom mount plate that could be dont with a piece of sheetmetal

I just got a dizzy at the jy for $30. They are selling them new for $109:
http://cgi.ebay.com/ebaymotors/ws/eB...m=190158612091 $98.10 when you use the discount code "hondatech"

All the connectors are easily made free with deep pockets. Someone with a soldering iron and a little experience can bulid the harness. The real problem is mounting the dizzy.

If we go through with this, I will buy two adaptor plates with cam spacers.

Doesn't it hit the water pipe below the distributor when mounted like that? I've noticed on mine that there is a drain on the bottom that would no longer be on the bottom when rotated...

I'll just throw in some random thoughts I had before I went off the deep end into Megasquirt land with a distributor-less ignition, and was considering doing a swap to an electronic dizzy.

It *might* be easier to use a dizzy from a 3g Prelude instead of a 4g Accord. From what I could tell they have basically the same guts but the 3g Prelude dizzy is the same size as an A20 dizzy. So it might be a little easier fit. Probably not as plentiful as the 4g Accords though.

An adapter plate is a good idea but I'm wondering about how you are going to do the spacer. Would it maybe be easier to just make a new longer key?

I'm interested in this, It would allow me to mount my distributor closer to the head. And I may not have to make custom plug wires any more.

Weren't most of those still obd 0? A new, longer cam key seems like the best plan to me.

[guaynabo89]

You can mount the dizzy without doing anythign to the key if you mount it like this.







All you have to do is bend/shorten etc the hardpipe coming out of the cylinder head so that it clears the distibutor. Then either use some brackets to hold on the distributor or make a thin adapter plate like openloop did. It looks like thin sheetmetal so it probably didnt push the distributor back at all.







And what do you mean not clean!

I think this looks very clean.
