a starion clubmember built a mitsu dohc 2.4 street rx7. Dyno'd 564hp using a $30 stock hyundai head straight from u-pull-it
If facing pumping money into a sohc, can't help thinking about all those $30 dohc marvels just sittin out there - lol

so the bare 2.4 sohc cyl head needs valve guides and seats installed, at minimum.
I'm thinking they can cut a 3 angle seat. Is it feasible to lap in your old valves (if they're fine) ?


My plan is to use the mechanical shaft & rockers from a 2.0 + performance cam + upgraded springs
Always preferred the smoothness and simplicity of the sohc, and intend to see how far I can take it boosted
