Ok so i have finally purchased an engine. k24a2!!! finally. now it came with an rbb intake mani and throttle body. i have tried searching and reading and i keep getting mixed answers(or maybe its me). if i use the rbb, i need an adapter to use my prb tb. if i use my prb i need to tap a coolant port on the head? would i be able to use the rbb tb(i am pretty sure youcant cuz its electroni).. whats the cheapest and best way?
