could i put a type-s head on my k20a3? and i f so how much would it cost?

 

yes u could but there is something else to do i cant remeber other then just swapping over the head

 

i was just thinkin of that same questions last night....would anyone care to elaborate on this...curious myself on the steps..etc

 

that something else you need is kpro (or possibly a prb ecu, not sure if that is sufficient)

the general consensus is that you may as well just swap the whole motor instead of doing the head swap

 

I think about it my self to do it ,
here what you need
k20 a2 or z1 head
intake manifold
throthle body
ecu ( need the go to honda dealer to set the key immobilizer )
and time cause you need to take the engine off of the car to loose the timming chain thats mean not shure but pretty confiant that you have to empty the ac but some part are not the same in the block k20a3 and are highly recommend to add to be swap into a k20a2 z1 . Like the crankshaft not ballance enought to spin at 8700 rpm (hondata reflash ) piston does not have oil squirter to cool down those oil filter is not water coolded . if you dont plan to change piston to get from 9.8 to 10.5 cp ratio i think your k20a3 will handle it nicelly but dont rev to hard on a unbalanced crank it make a big mess when it broke !!!
I do not confirm everything i say thats was the answers i get for the same question i post on montrealracing forum !!! take it or leave it !!!
