b16 dizzy cap

[velocitySiR]

yo what part cross references to a b16a1 dizzy cap because i need to pick up a new one...... i wouldn't think 2000 si ones would because i thought they were cap and rotorless, i'm prolly wrong tho.

Use one from the del sol VTEC.

Its the new type, and will fit your dizzy, but you need the Rotor and the Cap together, and as per my post in your other thread you have to change the grub screw in the rotor over.

I replaced my dizzy cap and rotor yesterday, the p/n for it is
06303-PR3-X00, but that's the p/n for a Euro B16A1. I assume Honda Europe gets these parts from Japan(??) So can't you order parts from your US dealer with that p/n?? I assume they also get it from japan(??)
I always wondered about that. I guess it isn't that easy and there is a catch but I just thought I'd post it.

Im curious, Bracer. Was the rotor and cap differnt to your old one?
Did the rotor have a complete circle of plastic around it? or was it an old single finger type?

Funny you ask, the original rotor was the single finger type, when I opened the box the rotor in it was a complete circle. There was a piece of paper with it which said "The shape of the cap assembly has been changed due to parts inification. Replace rotor head with the supplied one during installation"
I guess this means the original first gen B16A rotor has been discontinued, why do you ask? Is that a bad thing

I was just wondering if the change was universal.

The old finger type Rotor and the cap that went with it couldnt handle the high RPM of our little babies and were prone to cracking.
In some case's it caused obviuos problems like velocitySiR's but in my case I only realised it when I replaced the cap after advice from a Honda tech. Both the cap and rotor were cracked, but only causeing a small loss of power, that was only noticed when they were replaced.

The new cap and rotor design is much stronger, if you compare the two, the full circle of the rotor not only prevents spark jump, but also provides a lot of extra strength, and a close look at the cap revels larger and more side webs, as well as extra reinforcment around the base.

Bascily Honda continued to use a lot of parts from the old B20a from the prelude, the dizzy being being one of them, it worked well on the low revving lude engine, but couldn't handle 8,200rpm on the B16a.
(its not the same, but is very similar, just like the throttle body and intake manifold are not the same, but are clearly closely related).

ok so if i get the one off a del sol VTEC then do i have to do anything special to get it on......... that and i'm havin a hard time gettin the rotor off i don't wanna pull too hard and break it, is there somthing i'm missing.

[velocitySiR]

well i have a hairline crack in my cap towards the center, there isn't any moisture in it but would this cause my sputtering? i'm guessing it would because the engine isn't getting sufficient spark, but i'm terrible with electrical stuff.

the grub screw in the side!

Its small and you'll need a small screw driver to undo it. Then give the rotor a good tug to get it off.
REMEMBER TO REPLACE IT! when you put the new rotor back on.

Ummm.. my grub screw required an allen key

I still don't know why I had to modify the cap to make it fit. Everyone elses seems to fit fine yet the dizzy stub for locating the cap was on th opposite side to the cap.

My SiR is a bit older than moppie's, but in theory it should be the same design.

Moppie: I might take a pic of mine tomorrowand post it up for you to look at.

Cheers

[Moppie]

Oh quite whining!

Your car isnt that older than mine!

It sounds like you just stuck the cap on backwards!

I actualy took swaped grub screws on mine, so I honestly cant remember which it uses, but I know one had a flat head screw, and the other was an allen key.

Yep the rotor is bitch to get off, even if the screw is out. I broke my old rotor in 3 pieces before it went off
My car was also sputtering like crazy and the cap had a few hairline cracks as well. New cap solved it all.

Moppie, thanks for the clear explanation.
I didn't notice any power difference but it's nice to know it's better now

ok i realize it's 11:30 am and i went to a parts store on easter sunday, i'm the loser i never wanted to be, but i picked up a cap and rotor for a 2000 si the cap is completely different, i'm gonna go back and see if the 94 del sol vtec works..... i just pulled my old rotor off and there is a crack in that too, damn.

[EightOhOne]

For some reason im thinkin you use a dizzy from a 90-91 teg and you gotta break off one leg to make it fit right....but ill check around on the usual sites to see if i find anything so you dont have to go on a wild goose chase for parts

[velocitySiR]

yo i know it sounds dumb but we lined up the old cap with every single honda 4 cyl cap in there and the 2g crx one worked, i took it home and it fires, but on cyl 4 it sparks it but i'm not sure if the spark is enough to ignite under compression, keep in mind this is the same cylnder that the corresponding plug wire end snapped on then was semi- rigged back, so i'm gonna try a plug wire of my friends teg and see if the pile fires.
