what size shot?

ZW99GT

If you want to spray quite a bit you may look at the NGK BR7EF. I ran those in my car. I can't remember exactly, but I either melted a BR7EF or a R5724-8 in #4 cylinder (thanks to having the wideband only on one cylinder bank. lol). When really racing or leaning on the car on the spray, it won't hurt to go cold and narrow on the gapping.

R5724-8 (PN - 7317) two and a half steps
R5724-9 (PN - 7891) three steps
R5724-10 (PN - 7993) four steps

Is the NGK TR6 good enough for a 150 shot????

to be safe I'd go with the BR7EF. Have you ever used N2O before, if not start off small and work your way up to a 150 shot.

yeah i used to have an 03 gt before with

Patriot heads stage 3
typhoon intake
comp cams stage 2
75 mm TB/Plenum
Full exhaust
3.73 gears
Diablo tuner
fully built bootom end .40 over bore
and i had it sprayin 175 shot

But i wanted to get some ideas from everybody here how the stock engine with all bolt on mods are doing with 150 since i never sprayed my previous gt with stock motor.
