So i have very low spark on my 18r-c at the moment. And it makes it practically undriveable as you never know whether it will start after you stop and it misfires constantly. I am aware that it comes down to the distributor in this case. So i thought i may as well upgrade the ignition system rather than replace it. So i was wondering if anyone has done this to their 18r and if they could point me in the right direction of what i need to get and how i would go about doing the upgrade? Also if you have upgraded your ignition system did you get any power gain?

Thanks
