Hey'ya guys. I am planning on doing a full upgrade and a makeover to my HM Contessa (1983). The original car was made in the days when our economy was still not open to foreign trade. I really found the ride + comfort of the Contessa surpass most imports available today.

Anyway, I'm planning on doing a complete upgrade. For now, I'm focusing on the engine, transmission, and suspension. If anyone can give me an idea as to what engine, transmission+clutch can be fitted in the car, it will greatly be appreciated. I am not interested in smashing records. I am more in for the smooth ride. Here are the tech specs of the original components:

Any ideas on what parts can be used in the above areas will be greatly appreciated. I am not planning on refitting or repairing the engine. I'd like to work with new parts. Thanks for the time guys. The pic of the HM Contessa is on the thumb below.
