I am thinking of building a reliable race motor from my stock L Jet 1.8. I am thinking of increasing the bore and going to flat top pistons and slightly higher compression ratio, keeping it below 2.0 liter displacement. Either single heavy duty or dual valve springs and stainless steel valves, etc. I am thinking of using the L Jet system that is on it now, going to 2.0 liter injectors. Are there any performance camshafts that will work well with the L Jet, or am I barking up the wrong tree. My other option is dual 40 IDF Weber carbs and a cam to go with them. I'd like to try to use the L Jet if a suitable cam is available. Anybody done something similar? All comments welcome.
