I know it's a old post but hopefully I'll get a reply. I have a 2000 zx3 with a pw charger, short story I had kids and got married so the car was put on hold ( on blocks for 6yrs) I'm trying to use the parts I have 2.4" pulley , ford racing head , and rods. Just wanted to know if I could use stock pistons or do I got up grade and to what compression ? I know it's old and I'm having hard time finding parts for it. I can get 8.7 or 10.6 CR. I was looking for 9.1 as I believe that is stock CR but no one has stock.
Thanks for the help.
