One of the best feelings a car guy can feel in his life,is working on his own car.Yes it would be way easier to pay someone to do the job for you,but nothing can beat the feeling of knowing you have done something to your car,on your own.

Mr2mk1hero uploaded a video in his youtube channel,that shows the 4A-GE he built for his 1987 Toyota MR2.The best thing about this video is that he is an amateur,not a professional and this makes the video even cooler to watch.The final assembly took about a week,but all the work to collect the parts and learn all the skills he needed to build the engine,took about 2 years.
And in the end he said:
“it got me addicted to cars, engines [and] mechanics.” Now that’s the kind of ending we like.
