I’m not a trained mechanic and I have absolutely no idea if this is a stupid question. Can I convert the 220 turbo distributor type ignition to a later coil pack ignition? Or, can anyone supply the wiring diagrams for either engines? I now have a fully rebuilt engine in my 220 Turbo but was only getting one spark. Fitted a new cam sensor and all looked fine but it only ran for about five seconds. Now back to just one spark. I’ve got a 620 I’m using for spares and I’m wondering if it’s worth making the ignition swap as I have no idea what the problem is. Any advice would be welcome as I’m completely stuck and have limited knowledge. Thanks

Yes you can but it would mean opening the engine up.

You need replace the inlet cam, injectors, wiring loom and ecu from memory.

What have you checked so far on the ignition system?
I would think its a lot harder to retrofit the wasted spark system than to work out where the fault lies.
Did the engine run ok before the rebuild?

Sorry, I am a little confused
Please could you explain what you mean by "only getting one spark"?

I have the original Rover electrical manual and diagrams here (for the R8 range) and could probably take photos of the relevant pages for you (unless somebody else here already has a pdf version?)

Thanks for the replies.
So when you turn the car over you get one initial spark from the coil and nothing else. When the new cam sensor was fitted it ran for about 5 to 10 seconds then died now back to only getting one spark from the coil. Replaced coil, plugs, leads, cap, rotor arm, crank sensor.
220 GSi Turbo, any wiring info would be much appreciated. Thanks.

OK, I will dig my manual out tomorrow.

If you could PM me your email address, I can send you some wiring diagrams and discuss possible immobiliser issues with you.

I have a PDF of the 1992 R8 Electrical manual. Do you both want a copy?

[RoverRevival]

Are you definitely sure it’s only a spark issue?

You have fuel and compression.

[DiverJim]

Yes, have fuel and compression
Cromp 85, a copy of that manual could be useful. Thanks. I’ll pm you and 220 GSi Turbo.

Has anyone done that swap before?
