ok so here is the deal, i am going to go nitrous (zex wet kit) this summer starting off with a 75 shot. then i am going to save again to buy pistions and rods and crank it up to a 150 shot. do i have to buy a whole new system like a direct port or can i keep the first kit. because i want to do it right the first time. thanks guys for all the help

 

if you're going with a 150 shot you might as well go direct port. a single fogger kit isn't going to be very efficent over a 100 shot. you'll probably need a different manifold as well that you can tap the nozzles into.

 

he is right. a single shark fin will not be able to produce a full shot of the juice on anything 100-125 shot.. direct port FTW
