I have a distributor being rebuilt head to toe at Advance Distributors. Jeff (the owner) is also installing the Crane Optical. He says its as good as it can get for using a distributor. And that is from a guy that rebuilds them everyday. I trust his word.

Can you get the part number for the optical kit? Well, assuming you're using a stock dizzy as well....

I will as soon as I get it back. It may be a few more weeks. He is installing it in the distributor and getting it all setup. I just have to install the distributor and time it. Of course also mount the amp. It's real simple, Amp goes directly to the coil. Three prong plug from Distributor plugs into the 3 prong plug on the amp

Reading on the Crane page I found this-

When is a ballast resistor required?

A ballast resistor is required only with XR700 systems. Without proper ballast resistance, the XR700 and coil will overheat and fail. All vehicles with original equipment points ignition are factory equipped with ballast resistance. This can be in the form of a ceramic ballast resistor or a resistance wire between the ignition key and COIL- terminal. It can also be in the form of internal resistance within the coil, such as Bosch® blue coils (typical on VW) and Lucas® coils found on older British vehicles.

Good to know as we were talking about this a week ago.

Then I read about the 3000-

• All new status LED light for easy diagnostics.

• 150% greater spark gap energy over stock points ignition.

• Uses high output coil without ballast resistor.

• Optical trigger for precise ignition timing accuracy.

• Converts points type distributor to electronic ignition.

• Fully sealed for protection from dirt, moisture and vibra- tion.

• SMT=“SurfaceMountTechnology”forreducedsizeand greater reliability.

• Short circuit protection. • XR3000 is the high performance version of the XR700.

I'm not familiar with this system but to me it seams to fall short of the MSD 6 and their blaster coil.

Maybe I'm wrong.

If it were me I would still go with the 700 and then go to the MSD and Blaster coil when funds allow.

The MSD gives off a real nice, clean tach signal for when you go Megasquirt.

A $315.80 solution... HM.

Could go up $46.00 to the 6AL-2 digital version with 25/10% bigger numbers respectively. http://www.summitracing.com/parts/MSD-6421/

Or down $110.00 to the Streetfire with 5/10% smaller numbers... http://www.summitracing.com/parts/MSD-5520/

Hm.

I have no business even looking at this crap right now..damn you Pertronix.

Maybe I should just stick to the XR700 for a hundo. Grrrr

When I went through that process I decided on the Crane XR3000 and PS91 Coil, which cost around $200 together.

For another motor I bought an MSD to mate up with a 318i electronic ignition dizzy that would not fit a Crane optic takeoff. It works great, but the MSD is saltier than Crane.

For a 2002 motor, I would do the Crane setup.
