i used to do a lot of banger and saloon stox racing,many years ago.
fit a rad and fan in the car,where the back seats used to be.and use scafolding pole to connect it to the engine,
cut a side wall out of a tyre,and use it on the outside of the wheel,you will need innertubes to keep the tyre inflated,this stops damage and punctures.
2.0l engine,fitted with a 1600 cylinderhead.very high comp,difficult to start/may need 24v to the starter motor,but it will rev really good.wont last long,but who cares.
