greeting. transmission from the engine to the gearbox will be the belt (at the same time is the clutch and make-weight loss and reduction of speed or tension) I have 4 pulleys of different sizes all with 2 channels. that is mounted to the engine and the gearbox? what size? clutch will be by loosening the belt and tensioner lever with a roller bearing. no water pump radiator engine and therefore will be positioned above the engine. water circulation will be the thermosyphon principle - hot water rises, cold water down. must have a propeller mounted radiator for cooling water. I have the original exhaust. If something has put a muffler on a car? is a lot of work but it is my pleasure. I do not know if I can find to buy a Skoda gearbox 120. 1300 Dacia gearbox is not good? 4 speeds forward and one back. waiting for a reply and we thank you struggled to read me
