I want to do an all motor build but am having trouble figuring which ecu to use, lots say the p13 and the p72, but is it possible to use a p73 to attain higher rpm numbers? i have a jdm p73 ecu and everyone tells me that though it is a rare and useful ecu it can only be used by the b18c. i am curious as i want a high compression and high rpm engine.
