Can I use four 3SGTE Pistons on my 3SFE Block and Head engine. The reason why I'm insisting in this setup is because everyone does the same thing. Install the 3SGTE engine and your good to go. No, I want to develop this engine. Their are many 3SFE engine in Japan Turbocharged and Supercharged. When the owners of these vehicles stay with this engine. That means that the HP is their. You just have to work with it. On this island, the 3SFE engine is abundant. The 3SGTE engine can be counted with one hand. To tell you the truth, I've never seen one. Were can I get 3SFE forged pistons?
