EFI hardware sequential dizzy for a 202 run Haltech

http://www.efihardware.com/products/185 ... Holden-202

Just trying to work out which distributor option to go with my Haltech E6X set up on my 202. This dizzy is made up from a Holden VT 5lt dizzy with a custom made 6 tooth hall effect disc in it so there is 6 trigger and 1 pulse signal. im just not convinced its worth the 600 dollars seems rather high priced. It will give me the option of running 1 coil or 6 (ls1) coils. six coil set up the make a billet cap for the top of the dizzy for an extra 100 bucks.

Is there any other 6 cylinder hall effect style dizzy i could modify ??

That's pretty much what I'm using in mine. Didn't want to pay their ridiculous prices though, so just bought their rotor and hall effect and modified a standard EST dizzy to suit. Cost me about $200 all up.

Yeah they probably wouldn't because it's more money for them.

The EST dizzy has no internals, other than the rotor that points the spark to the correct cylinder. The EFI unit has rotor, the reluctor system to fire the coil, advance weights and the vac retard unit.

I don't have the part numbers unfortunately, but if you tell him you just want to buy the 6 cylinder sequential rotor ($110 from memory) and the dual hall effect sensor to suit (~$80), they should be able to give you the right bits.

Took me about an hour to make. Still need to get a cover machined up for it though.

They're very good to deal with. They're located in Mitcham if you're in Melbourne. They usually have the rotors in stock (think they make them), but I had to order the hall effect in (next day).

Yeah thanks mate ill try and get a est dizzy now and do it that way no worth 700 with there billet cap. Yeah i spoke with steve today he was extremely helpfull just over the phone. I went there years ago with a mate for fuel pump im on the mornington peninsular so about an hour away. what sort of cover you going to machine up for yours ? you running 6 coil packs ?

Yeah I'm running 6 of the D585 Chev Yukon coils.
I'm just going to get my engine builder to turn up a cover using the dizzy cap as a guide (but with a flat top)

Nah the D585 coils put out triple the spark energy the LS1 coils do.

LS1 coil (D581) - About 40mA peak secondary current

Image

LS2 coil (D514A) - About 80mA peak secondary current

Image

Yukon/Truck coil (D585) - About 120mA peak secondary current

Oh look, the LS1 coils put out a fair bit of spark. Certainly for NA or mild boost applications they'll be more than enough. Especially if you've got some already!
