my friend is selling his NOS nitrous direct port setup off of his LS integra, i was wondering if the 7thgen can handle a direct port setup? and how much jetting? i dont know how to bend those lines and can i dont wanna drill into my manifold. can i just hook it up to my intake?

that wouldnt be a direct port. that would just be a dry kit.

There are a couple of things that you need to do to get a direct port set done right. You need a flairing tool and a small tube bending tool that you can pick up at napa to do the supply lines. All of which need to be the same length. The problem with direct port is it's for larger shots of nitrous, which our cars can't handle. because of the plastic intake manifold and weak internals. but also when you do direct port to ajust the different shot sizes you need to adjust the fuel pressure, so you need a better fuelline, fuel rail and adjustable fuel pump. The best way to figure out the jetting is to just call NOS or NX or where ever, they have the jet sizes to fuel pressure ratios you need.

The car certainly couldn't handle it with out some upgrades, exspensive ones.

Actually NOS sells a direct port kit that also adds fuel making it a wet kit.
