b series dizzy rotors

[vinnY]

they all the same?
found the part number for the b16a2 dizzy rotors, can't find a b18c one to match it up to though
guess it's about time i replaced mine

[Slaz]

I believe they are.

[vinnY]

cool as
well i should have a definite answer tomorrow :)

[vinnY]

just a fyi to everyone
it is indeed the same, design's a bit different but it fits the same

seems half of the contact was pitted and burnt

vinny get the solid metal Vision Motorworks one from eBay shop autodinamics

had the same prob.. was getting inconsistent spark coz of the burning/pitting.. plus thanks to the ricey clear dizzy caps i was also able to realise the rotor burning because it was glowing.. i got a youtube clip of it if your interested?

[vinnY]

you showed me the glowing rotor remember? ;)
it's okay, changed it already with an oem item
changed my timing a bit though strangely enough had to hit it with the timing light again

car drove fine, just had an odd shudder around 2-3.5krpm(which i've actually yet to verify whether it was the problem or not) will find out soon

edit; fyi did not fix my chassis shaking problem :( car does seem to drive smoother though

yeah when i reset my timing on the rooted rotor, it was off randomly between 1-2* when i installed the new one because of the spark jumping at random points on the rooted rotor contact.

the new solid metal one perfectly sparks off the middle everytime

[vinnY]

say changing the rotor shouldn't affect timing hey?
i realised after changing the rotor and reinstalling the dizzy i had to retard the timing a bit to get it back to the stock 16deg
shouldn't happen right?

[tinkerbell]

could happen,

the rotor is the direct contact for the spark timing, even a little movement in where it sparks from can change the timing.

make sure it is on properly, but it could also have changd due to the pitted busted ass one sparking later as it was further away?

[vinnY]

yeah sounds right actually
rotors on fine, sparking on a different position on the rotor would probably make the difference since only about 1/4 of the old rotor was actually not burnt and pitted

double checked the timing again today and it seemed to be spot on(knocked it back to how it was before just for giggles, WAYYYY advanced looked about 7mm away from the 18deg marker)
