RS Motorsport :: Classic Speed Restored

Hi guys I have a genuine rs2000 auto and trying to keep it original as I can and would like to keep the auto but upgrade it so it can take abit more power ect ect but shift kits and stalls are pretty much unavailable does anyone know if there is someone I could take it or send it to that could upgrade it and make it abit more bullet proof? Or know of a conversion that would fit and would be a touch more heavy duty?

thanks warren ive downloaded vizards book but he seems to say that the c4 is the auto used in escorts is he confused or me i had the understanding it was a c3 in the escorts

the heading of the chaper says Building a c3 automatic for high output engines but all he talks about is the c4?

Burpengary auto. Mick the owner can help.
