I know the SOHC vtec is nothing like the DOHC vtec, but how much better is it than a non vtec SOHC

 

From what I hear, it's just maybe another 10 hp.
That's why I've never even thought about doing a mini-me swap.
Only problem is that the non-vtec is hard to find cams and such for.
If anything, if you want vtec go DOHC.
