Thread: Which replacement Coil for 2.25 Petrol

The "R" means it needs a Ballast Resistor, I believe, and the non-R version does not. The non-R version suits electronic ignition, not points.

So, unless you've converted to electronic ignition, you need the GT40R.

I could be wrong, but that's my understanding.

Not always true as disco and range rovers use GT40R and RT but they also have amplifers as well

In my stage 1 I am using a disco coil with no electronic ignition

Part No
0 221 119 030 (for a series 3)

Gday Mate,
I replaced my coil on Saturday. Just went down to Repco and got the one from their catalog. Ill pop down to the shed and have a look what it says. Works like a charm, the car has never started so good (i suspect the old coil has been on its way out for a while)

EDIT: Been to check...appears I have the GT40R... Works a charm :-)

Your a gem Josh... Thanks for clearing this up for me.. All the best Phil

Another little tip, make sure your coil is wired the right way round. Negative (-) to the distributor. I spent ages changing burnt points every oil change in my KE20 Corolla until the mate I mentioned before pointed it out. That car had a dual circuit ignition.

Also on coils, the other day I had a friend burn one out on his S3 just by leaving the ignition on without running it. NB: it was a cheap coil though, made somewhere in the backblocks of Taiwan. I fitted a second hand GT40, and now it goes just fine.
