Hi there a few of my friends in the youth class up to 1400ccm drive I wanted to ask what such a conversion of a car costs if you can do it yourself. and which is a suitable car. a friend drives a polo v 16 with 101 ps. since I would like to tinker with him I would like a good car that is drydem cheap. then I would have another question to remodel. I asked a bit and found out that you can only use serial cars. can i trozdem if i e.g. ine polo with 75 ps has used this with 101 or is that no longer a serial car? dnake
