I will be runnin direct port nitrous, but the 1g b16 mani is kinda cramped for space. So I am wondering if it would be ok to put the nozzles on the bottom side of the mani. Would this hurt anything? Would this be too dangerous?

Also, if I wanted to run a 100 shot, then would I put one 100 shot jet at the distrbution block or would I put a 25 shot jet at each nozzle?

 

no prob w/ that...make sure its all tight. i got a kit for sale.
430 w/ everything

 

That's how I have mine, but it's with a victor x manifold and the nozzles are pointing straight towards the combustion chamber. Your's will probably be pointing straight up, but they have nozzles for 90 degree aplications. You'll want a 25 shot jet at each nozzle

 

it's ok. a lot of people place them on the underside of the manifold. however...it's a bitch to change jets if you ever need to.
