Hi friends!
From the title of the thread is clear about what will be discussed. At the moment there is a spare 4G69 engine. With this engine I'm conducting different experiments. It will also be a great and interesting topic. Probably a couple of months. When I get results. For this project, I try to use all possibilities to increase the capacity.
In this topic I want to talk about making the lightweight crankshaft pulley. I've seen a lot of graphics power, those who set up such a pulley. This gives you about 5-7 HP. And faster acceleration of the engine.
Originally I wanted to just buy on ebey. But unfortunately, found nothing suitable for a 4g69. There are a few pieces for the EVO. But with a caveat.
Firstly, they're all reduced size. This is not good. The power steering, pump, alternator and air conditioning will not work properly.
Secondly you have to choose the size of the other belt.
Third, they mainly made in China. Now I will tell you in more detail.
