I was wondering what a y8 block and a6 internals, crank,rods,pistons with a z6 head be like? stock or a higher compression? and I have found some rods but I wanted to know what do I need in fuel for a 75shot of nos in in my y8? any info would really help.

 

Your gonna have to bust out the compression calculator for that. I like this one, http://www.zealautowerks.com/dseries.html. Looks like its around 9.7:1, which is a little high, depending on if you want to go turbo or stay n/a. Play around with the calc, i calculated it with a a6 head gasket, which is the thickest so thats the lowest compression you can get with that set up. As far as the nitrous, Most systems like Zex add additional fuel with the nitrous. All you really need to do is get a colder step spark plug to handle the higher heat.

 

SOHC injectors cannot handle 75 dry shot............

 

ok, but what about wet shot of nitrous?
