Before you will start a conversion, be sure you have the time, space and patience for it. DO NOT RUSH!
Having the right tools will make the job a lot easier: a rachet set, wrenches, screwdrivers, soldering gun, torqe wrenche, pliers, engine hoist and some small tools. When you do not have a engine hoist you can rent them at several stores. For your own safty use a jack and 2 axle stands!!
When swapping the engine some small welding needs to be done. A welder and a grinder are a must. For turning down the cranck pully in a Corsa A – Nova swap you need a laithe. This can be done in your local machine shop. The same goes for building your own hubs and driveshafts.
