Hi legends!
I've just purchased a complete front cut JDM accord with the H23a Vtec engine. I will be putting it in a '72 Citroen DS.
I have gotten my head around the ECU and tuning, I need to purchase a P28 ECU with a OBD2b to OBD1 conversion harness and get it chipped. The H23a will remain stock internally.
I will use the original DS gearbox as it has inboard disc brakes, these boxes are used in the early Lotus Esprit so they are good for 200+ hp, but I still need to figure out the best way to couple the engine and gearbox together, the DS engine spins ccw, is a front mount, N/S configuration and the gearbox sits at the front...
As I can get a stronger DS clutch and longer input shaft, if required, I think the best thing would be to machine the DS flywheel to mount on the H23a and machine a gearbox adaptor plate. This will also allow me to use the DS starter but I am unsure if it's location will suit the H23a atm as it sits on the engine side...
The other option is to adapt a H22a bellhousing to the DS gearbox and maintain the Honda flywheel and clutch. But then I have to worry about the input shaft matching the Honda clutch as well as the odd shape of the H22a belhousing.
Next is how to run the alternator, a/c compressor and the hydraulic pump (which controls the brakes, steering and suspension) as I doubt there will be enough room or any access at that end of the engine, as it's squashed in to the fire wall...
Here is a nice section cut of how the motor sits in the engine bay, note that the gearbox sits forward underneath the steering rack...
Any ideas,support or suggestions are welcome!
Cheers,
Harley
