Put 18rgu in ke30 has electronic dizzy do I need to change coil. It has a gt40r and ceramic resistor, do I just get a gt40 and get rid of the resistor. I have read a few comments about this but there is so many different blogs about this it's all just confusing. I'm pretty shore there is only 1 wire on the dizzy I will have to check.

You could change the coil, the resistor coil is designed to run at a lower voltage than the non-resistor GT40, and you're probably tripling the voltage being fed into it. On the rally Celica Steve fitted a GT40 with the Spitfire electronic setup.

 

Then again, I fitted the 5K electronic dizzy to my KE70 and never touched the coil. If it dies I'll replace it then. Just run the GT40R without the resistor fitted and open the plug gaps to about 35thou..

Thanks mate

I'll do that
