I have a c20xe (coil pack version) and have jus got twin 45 carbs, could someone pls shed some light on wat I need to do the conversion and if I can do with coil pack type engine as was under the impression I needed the distributor type...
I think there is but have seen somewhere u can use coil pack, which I'd prefer to do as better ignition, jus want someone to confirm it really...and tell me wat parts I need other than inlet and management. Cheers
if you want to run a dizzy setup you will need to change the exhaust cam for an early type. then use a dizzy, coil and ignition amp setup from a mk2 cav 1.6/1.8 (check the drive on the dizzy as it may need changing for one from a xe dizzy)
or ring h+h ignition (0138 4261500) and tell the what your doing and they will supply evrythnk needed for ignition side of things.
or you can use megajolt witch runs a ford edis coilpack IIRC
when wiring the coil, there is a square black plug that joins the starting/charging loom to the c20xe loom. use the black wire that runs to your coilpack and run it to the + side of coil
you will need a bike fuel pump or a facet type with a pressure regulator to drop pressure as carbs only need around 3/4psi
Most distributor conversions seem to be just for RPM, which is fine if you just drive flat out all the time and don't care about getting the best out of the engine.
There are a number of mapable electronic conversions around, which have the advantages of having exactly what 'curve' is needed for best torque/power at full throttle AND can further advance the ignition as required for part throttle use which increases torque and economy. They also tend to work with what you've already got fitted.
An example is SBD Motorsport MBE9A4i ECU bit pricy, perhaps, as a little over 600quid with the Weber TPS, etc - however, with the cost of petrol, it may pay for itself in short order if you use the car a lot around town.
H+H uses the cavalier setup and sells it as a kit. it has vacuum feed for engine load reference
i thought you could use a dizzy on a coil pack cam, but not the other way round. theres an offset threaded hole where the cam rotor bolts too which i believe is in the same place (dimensionally) for the offset peg on distributor.
Agreed, TBs would be (was) my choice, however, some people just like carb's or they may be a requirement for some types of class racing.
With the money for selling the carb's and manifold, there wouldn't be that much difference for a 'turn key' TB installation.
Tbh I do intend on goin throttles at a later date but I'm doin carbs as a temporary upgrade as I got almost brand new 45's off my pal for cheap! Cheap cheap! N one of my gd pals wil map it set it up etc for just a drink...
Any u could recommend using? And does that mean I will be able to use on throttle bodies as well to save doing at a later date?
I don't see why not, effectively you're using everything except the injector map, outputs and lambda - they may be able to be disabled in the mapping or, perhaps, a dummy resistance used if there's a problem with an open circuit..
Have a word to the guys at some of the places that sell the the full EFI conversions and, perhaps, try contacting the manufacturers of the units.
