Hello my query is the following: I have a Renault diesel trafic 2.2 model 94 which I bought for family use. What I did not take into account is that the ratio of engine and gearbox comes to use it as a vehicle d load x what has strength and a maximum of 90 km / h with the very demanded engine. The question is if you can change \ adapt some engine and diesel box of another vehicle to give the use that I want from now I hope some help thanks.
