OK, admittedly I'm not a toyota owner, but I'm still a gear head and we all need help once in a while.
I'm trying to find somebody who is intimately familiar with Toyota's VVT system who can help me with some technical questions. I'm in the process of building a Mercedes 2.3-16 into street/track toy, and I think that there's a good possibility that I can reverse engineer the VVT system onto my older engine.
The engine is a 2.3L inline 4 cylinder with a cosworth designed 16 valve DOHC head. The cams are chain driven. I got the idea when I noticed that many of the new generation inline 4s that Toyota, chevy, ford, and nissan have developed over the last few years bear a remarkable similarity in design and specifications to the venerable Cosworth engine that I have. My reasoning here is that despite its age, my engine has what is still a very modern design which could concievably benefit both in term of HP and efficiency from variable valve timing.... besides, it sounds like a fun waste of time to try it.
Anyway, IF the early toyota VVT systems weren't computer controlled, but relied on something simple like rpm to determine the timing, and IF the timing mechanism is carried completely on the cam gear, then I think I have a good chance of success. What I need is somebody who can give a detailed description of the system, and maybe provide some detailed pictures of the mechanism.
So what d'yall say? Can anyone help a brother out?
