i have a base rsx, with the k20a3 engine, and i've been reading posts about how it differs from the k20a2. i haven't read a concrete conclusion saying that it's possible to change a couple parts on the k20a3 to make it act like a k20a2 when it comes to hitting vtec. after changing those parts, a hondata can take care of the ivtec engagement. what other information am i missing?

 

You pretty much have to put a a2 head a on a3. you can't convert parts really.

 

so if i put an a2 head on my a3 motor, will my motor be running like a type s? (after all the ecu changes)

 

new tranny as well

 

crap that's a lot of money.

The water passages are different, A3 has no oil jets, oil pump is smaller, has a different pickup, and aswell as a different pan.

 

crap that's a lot more money. am i looking at around $2000? what if i got aftermarket products for the things a type s owner could replace?

 

Most people will tell you it is cheaper to find a k20a2 swap and keep your k20a3 as well.... Some people sell k20a3 swaps for 2400 on ebay....
