i just got a nice deal on a zex kit, and just found a good deal on a built GSR head. I'll probably get it and mill it enough to get 11:1 CR (stock is 10.6:1).

anyway, i know when it's tuned for all motor power it's probably not safe to spray it. I've always heard that you should use 2 step colder plugs and retard the timing for N2O.....but advance timing for all motor power.

So how do i do both safely?

one thing i was thinking of doing is buying a VAFC just to richen it up 15% every time i wanna spray it. Would that be sufficient?

TIA.

SOHCmaster

The higher the compression the bigger the shot..

SOHCmaster

Advance cam gear 2deg and retard timing at least 4-9 and or spark retard if running MSD unit with this built in. Step colder and full 75-100shot all day.....

id double check that retarding the timing 4-9, thats alot and a big difference from 4 to 9.

well i understand that retarding the timing would be safe for the n2o, but what about for the rest of the time...since this is my daily driver i want it to be tuned for nice all motor power.
