So how big ahve you seen or heard of a 2.0 liter type 4 with a tweeks stock FI setup???
I need to know specs, I know 2056 works, I feel that it could go bigger, I am thinking 2.2 possibly, with a higher CR and a web cam, ported/polished heads. I would like to hear Jakes real world trials to see how far he has gone, I know he has tried big displacement with the stock FI, I just want to know where the line is?? On that topic, how about 2.4 liter using the 4.8 liter mercedes injectors (they fit and have the same voltage requirements, and an old porsche race team mechanic said he had done it before) Any thoughts?

I am not an expert in mixture stuff by any means. I got a Wideband O2 sensor so that I don't have to be :-)
I am pretty sure that running lean causes extra heat. It can also cause burnt valves. Turbo engines running lean can cause catastrophic results. Beasically - I think if ytou are running lean you get an explosion instead of a controlled burn. This can also burn your valves I think. Running rich doesn't seem to do all that much, but it does cool things down, and causes some build-ups that are bad. Lean also puts out more power from what I understand. Our engines are supposed to run slightly rich of ideal (stochiometric point) which I believe is 14.7:1 Air to fuel. I think we are supposed to run at about 12:1 or so. l8r, Fiid. |
