Would it be possible to take the coils and cdi from a bike engine (carb model engine) etc and fit them to a car engine to control spark?

The old zx10 i had was quite simple and the cdi only really controled the spark, i know i need the crank sensor but this could be fitted to the engine or just use the original sensor and splice this to the bike setup.

Just wonering if its been tried as im temped as its locost lol. planning on running a k-series on bike carbs and this would sort out the spark.

could be made to work, but why not just use megajolt?

Ray

because im skint as f**k because me n our lass have just bought our first house lol.

Plus i can get the bike parts for next to nowt.

You could but you'ld be lucky to find a bike ECU that matches the ones you require for your K series....

ie from a ignition map point of view. The timing will likely be wrong (for maximum power at least)...

get the cheap bike parts, ebay them then build a megajolt with the £££

The coils and HT leads would probably be just fine. The CDI will have a timing map to suit the bike engine. Even if you got a suitable crank sensor on your K series (probably not that hard) then the timing will be pretty poor.

It will either run with limited power, will run rough or may not run at all.

edit to say, actually, you might be lucky and it runs just fine. It depends how much your engine matches the bike engine.

How much would it cost to build up a megajolt system to control the spark?

Approx costs for what i bought

Megajolt kit - £50
Coilpack, EDIS4, VR sensor, TPS, Leads etc from breakers - £30
New cable for loom - £15
Shielded cable from Maplin Electronics - £4

So all in you will be looking at around £100 - £120. Definately worth it and as said the bike ECU is likely to have a totally unsuitable map.

didnt realise it was so cheap, might as well go megajolt then. Whats the best place to order the kit from?

Thanks for the replys guys.

Forgot to add to the list above - you will need a trigger wheel to bolt to the crankshaft pulley also. Mine was about £10 although you can get them from a breakers yard too off certain Ford's

As for suppliers, try dropping Paulf on here a U2U to see if he can help. He supplied my kit to me a few months back. Took under 2 hrs to solder up the kit and is pretty simple following the instructions.

linky

Cable i bought from Vehicle Wiring Products and ordered it in the proper colours with lengths to suit the car.

You'll need parts from a breakers yard off a couple of cards so try a search for recommended bits and what car to find them on

i think im going to go with bike carbs so am i better off finding a set of carbs with a TPS already on?

If you can yes - R1 carbs have them on already but am sure there must be others
