So my friend recently blew up his bottom end in his rsx type s and hes giving me the head off of it. I see alot of people saying its a waste of time and money but im also changing out all of the parts in the a3 block to the a2 parts. Ive been doing alot of reading and haven't been able to find any information on what I need to do the swap. I plan on turboing it after it after its all built. Here are some of the questions I need answered. Do I need a rsx type s ecu if I run k pro or can I still run the a3 ecu? Do I need to use the a2 intake manifold or will the a3 be able to work? What is everything I need to buy/do to put the a2 head on the a3 block for it to run right. If you kniw of anything else I need to do for the swap please let me know.
