SOHC Ka vs. DOHC ka

The new rules have not been released yet but the rumour is you can run any N/A aka no turbo motor sohc or dohc 4 cylinder. Any nissan motor can be used in a Nissan, any honda motor can be used in Honda etc…even if a certain model never can with a certain motor

RB30E/DE!!! N/A!

Still, if thats the case, don’t stick with the KA, theres tons of options, only reason to stick with KA is if your on budjet.
