someone probable ask this already but is it worth it to put a k20a2 head on the k20a3 block, someone said it was a waste of time or something, but i wanna get some opinions. just trying to find out the best way to do my car.

 

not a waste of time, but you will need k-Pro, and you can have a full A2 long block for just a little more than the price of the a2 head. the 5 speed gearing is not great for either set up, so just save for a complete A2 (type S) swap or boost the A3 and you will be much happier.

aiite koo thanx homie

 

I have the same question as you , sorry I can't help you out. But I believe it would be a good combination because the A3 has better torque than the A2 stock. Good luck with what ever you decide. Later

I thought that this was another thread, posted just a week or two ago...

Anyway, a link to the next-previous thread about an A2 head on an A3 block:
