Ive been reading through all of this and I'm new to turbos. I still havent decided whether I want to turbo an M50 or an M20 engine. I like the M50's much better. I have a question about what i need to physically run the turbo system. I understand the hardware, but as far as tuning, can I get a chip to plug into the DME (OBD I) and then I'm set to go? I don't know how that controls spark advance/retard and fuel. Do I need to get a piggyback ECM or do I need a complete new ECM? Also, For a turbo controller, what does that even mean/ Ive tried doing research, and even on noob forums im a bit lost. Any good books to read on the topic? Im looking at one now called "Performance Fuel Injection Systems" by Matt Cramer/Jerry Hoffmann. Its mainly for V8 systems, and everything is specific to them.
Thanks in advance. SICK car man. Very well done.
