Well it's about time I got moving on with my original plans for this car. My original intention was to build it as I would have done back in the 80's and then after a few years of running it like that start to progressively modify it using period parts right through to a full modern management and EFI. So, I'm starting to plan the approach and direction I want to go.
My car is built using period parts and looks like it could have been built in the 1970's or 80's and I want to keep any modifications as subtle as possible. I've been planning this for a few years so have a good idea of what way I want to proceed and I've gathered together some of the hardware.
I will probably be using a single 48mm throttle body with an home made alloy plenum style manifold, adapted from an MGF, complete with MAP sensor, injectors, fuel rail, pressure regulator and various attached sensors, a Bedford CF Bosch JHFU4 Hall effect distributor with a Bosch '008' type (Intermotor 150000) ignition amp and matching Bosch coil.
At the minute I think that a semi sequential injection configuration would be best suited as the injectors will be mounted quite far away from the valves and injector timing will not be so critical. But a 2 channel injector board will limit my options if I choose to go fully sequential for some reason.
The object of this build will be to do it on the cheap, do as much as I can myself, to keep the installation quite discrete and do something different from the norm. This route rules out the now quite common 'Jenvey' style individual throttle bodies.
I've looked at the Patton Engineering Stromberg carb injector conversion kits which are super discrete but those are quite expensive and the Strombergs are very restrictive and won't flow enough air for future tuning options.
All this will be managed using a DIY ECU. The Megasquirt system is the best known of these but the design is now quite old and kits are becoming expensive for what you get. I'm considering the Speeduino ECU which is still very much in the development stage but already looks very promising and relatively cheap too.
I've already been running the CF distributor for a few months and it really needs the advance curve altered to make the engine run really well. This is what has prompted me to get moving on this as the ECU kit and software will give me programmable ignition straight off for less than the price of a mechanical re-curve.
