do i need a piston upgrade on a Mini-Me?
 

I have no idea what the pistons on my D15B7 look like, but I figure that those on the D16Z6 head I want to swap onto it have a noticeable valve relief, seeing as how they have to accomodate valves that are pen for a longer period of time (VTEC, of course). Is there any difference between the top of these pistons? And if there is, do I need to switch to them in order to have a successful Mini-Me? (and avoid smashing my valves to bits)

if its a 8v 1.5 its not gonna work ... itll only work if its a 16v 1.5 ... so it has the valve relief..

it is a 16v... all d15b7's were 16 valve. So I do have valve relief on my stock pistons then?

yes it will work as long as its 16v .. it has the valve reliefs...like this 1.6 does..
