Measure everything

Engines come in different shapes and sizes. For example, bores can be wider or narrower; camshafts can be longer or shorter compared to others. Measure all the dimensions you can find. Count also the number of parts you will need. Only a fool would buy a kit for a 4-cylinder if the engine is a 6-cylinder. These are just some of the few things you need to count before buying a set. With all these numbers in hand, refer to the supplier's catalogue to see if they have the right kit for you.

By this time, you should've already set a plan for yourself as to what you want to do with your engine. This will help you in picking the exact contents your kit will need. Manufactures know that not everyone needs a complete engine rebuild. Some just want to work on their pistons, while others would only want to tinker only the frame itself. Aside from the basic rebuild set, there are also high performance kits available for those who want to get more power out of the engine.

Tips:

Label all the parts to help you with reinstallation. You can also record a video of yourself doing the disassembly.

Don't hesitate to let an expert do the rebuild for you.

Have lots of patience, and you'll earn an improved engine
