not a dumb question, more like a heavily covered question .

 

An for the love of <insert deity belief here> It's VTEC not VTECH, we don't put phones in our cars.

Since you are new, I would suggest looking at the FAQ's at the top of the list and read threw things that may interest you.

 

i have the stock d15b2 witha mpfi swap the only thing in that post about (vtec) on that link is on a d15b7 i think would the z6 head work on my engine?

 

It's exactly the same procedure for any bottom end that is not factory VTEC.

 

you can use either a z6 or y8 head
