Wow !!!! So narrow minded!! The thing is in motorsport you are in different classes, and the lower cc's are very competitive, so you need to broaden your horizons as they say... the C16XE (corsa gsi engine) designed by lotus, with minimal modifications makes good power and is very reliable, the x16xe (corsa sport) same engine block as the gsi with slightly different intake setup ... thus chap has asked a sensible question being the vauxhall engine makes good power, light And reliable, and the k11 micra is a very very good handling car even in basic form so tbf its a good combination to build a competitive car... also many people on here run various conversions from other cars... Still makes them micra..... just saying ....
