what about a b7?
It will fit just fine, but you'll need a d16y series cam gear or an adjustable one to move the cam timing 4.5 degrees to get it at TDC.it will fit the b7. im not farmiliar with the z1 sorry. i have the b7 so thats what i know about
Not good performance ones.cool. can't i just go to any auto zone and order the piston and rods??
