We are doing our first in-house engine build at the throtl headquarters! In today's episode of throtl, our new mechanic Quinn begins the process of our 4G63 engine rebuild. The first step to any engine build is to strip the entire engine down and make a list of all the parts that will need to be replaced. Stripping the engine down is an essential step to checking the quality of the engine and getting it ready for a rebuild. Check out the video below to see a detailed process on how Quinn stripped down the engine from our Mitsubishi Eclipse GSX.
