Nevertheless, definitely a great project with the V6 Transformatiin, it was not meant negatively. My son finds the conversion to V6 very cool, he himself drives a tuned 4 Cyl. NA for years.
Here in the link below is an American version of a conversion that you can officially buy there. In the specs at the end of the report, however, the 2,700 lb indicate about more than 200 kg extra weight, which, however, is not only one-sided front add but also the double-flow exhaust system, etc. makes weight. Sure a lot of fun.
