Ok, what are the physical differences between these 2 engines??
What is it that gives the Redtop that 14bhp advantage??
The reason that I am asking is that I know some of the Redtops share the same bottom end as the Ecotec (including the G50 idler wheel) and these also have the head with DIS module.
What I'm thinking is that if I can get the head off one of these it should go on my Ecotec with all the Ecotec management system without too much of a problem.
