I'm getting ready to build a 2.0 engine for my latest 914 project. I've put together several of these motors in the past but have always used the Euro type Mahle 94mm pistons. How big of a piston can I use and still retain the FI. I can make minor modification to the FI if need be. I've done this in the past. Has anyone out there try this?

My engine is a 78 x 96 with a mild webcam for FI engines. It has been together and running extremely well for 10 years. I've been driving very hard at autocrosses for 8 years and it doesn't even leak a drop. And yes I built it! It does not run lean anywhere. No it does not make as much horsepower as Jakes, but it is a torqy SOB and it was probably less than 1/3 of the cost of his. I built this engine to pass smog and it did...barely. The compression is around 8.1:1 The fuel pressure is around 36 psi. Early 2.0 manifold pressure sensor/injectors (supposedly flow more gas and cheaper at the time). Stock rev limiter, larger or bored out throttle body. The big deal is to trick the brain into thinking its cold outside, so put a resistor inline with the head sensor. Mine took about 400 ohms resistance to accomplish this. I determined this with an O2 sensor in the exhaust and later it was checked on a chassis dyno. Do a search it has been discussed here before.
