1.8 Liter Race Motor Questions, L Jet and Cam Options

[motorvated]

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.

Found it in the 1972 GCR

1.2 mm bore
So a 95mm cylinder would be legal
But not 96

It’s a rule created to allow water cooled cars to salvage their blocks
Not intended to create a performance advantage

The throttle body size is also regulated in the 1972 PCS
But carbs are accepted and solve that problem as well as work with a real race cam/high lift/more rpm. You can buy JE pistons in any compression ratio you want
