I'm running a NOS wet kit on my 2.8. It currently has very very low miles on it (Bought it in December with 75miles on the engine.)

I don't want to anything crazy to it. I'm looking at a 50hp to a 75hp shot of nitrous. I have a bunch of different jets, so I can try out different settings, but I would like to know about other people's experiences with N2O on the 2.8 and what's a safe amount. I bought a book about what nitrous is, how to install it, and how to use it and I'm pretty confident in my ability to not do anything stupid with it.

I'm going to be asking a few questions after this one, so bear with me.
So for this post:
What size jets should I use for N2O and Fuel, and what HP rating should I shoot for?
thanks.

Just don't drill into the valve cover.

Bump for ya, I kind of want to run a 50 shot on my Turbie.

I don't know if NOS is the same, however I do know the NX nozzles fit into the NOS 'shark tip' thing so they might be similar. My NX kit was rated as:

HP N / F
35 31 / 18
50 35 / 20
75 41 / 24

hmmmmm that's a good idea... I wonder what N2O and fuel would do to the engine in there...
Bet I'd get an awful lot of pretty colors!

any particular reason your going with a wet setup? Usually that's for larger shots or carbed setups where the factory fuel system can compensate on it's own. I have never run a dry setup myself, but plan on it so I'm not dumping fuel into a plastic factory manifold on a 3800 series II n/a engine... figure I'm less likely to blow a very expensive manifold apart that way.

My 289 Mustang ran a 175hp (never stepped up to the 250 jets... couldn't hook it up under 90mph anyways) Cheater setup from NOS.... now that's a blast (even more so if your fuel system leans out... and believe me I know from experience). Turned 12.56 at 116 mph on street tires with a 2.1 second 60 foot time cause I could never make it hook... Ran 13.90's off the bottle at 98mph.

Light the wick :-)

Check with the manufacturer on jetting. They will be different depending on the designed operating pressure of the system. Some are designed to run at 800psi, others run at 1100psi. This will effect jet sizes. Running a jet designed for the 800psi system in an 1100psi system will cause it to be lean..........Paul

I just installed and deinstalled a dry NOS system on my "87 with 66,000 miles. Oh, did I forget to mention that it was deinstalled since I basically destroyed my engine, @$&^!!!!!! Yes, I neglected to do a compression check on the engine before installing the N20, or I would have found a weak cylinder. Well the N20 found it for me. The number 6 cylinder has a blown oil compression ring and perhaps it has all the rings destroyed. So- I would advise staying with a low HP shot if you are not having any problems.
I suppose that to put N20 on any engine that's 16 or more years old without a thorough system check, is not a great idea. Ed

Excellent point by Firefighter1, if your engine has any underlying mechanical problems nitrous will find them for you ...Paul

Well, like I said already, this engine is practically brand new. And since I bought the car last year I've been pretty much babying it. I've blown up 4cyls before from romping on them too much after being rebuilt.
I don't think I have anything to worry about on the mechanical side. But when I change the spark plugs, I'll get a compression test done.

The reason I'm running a wet kit is because I don't want to have to mess with injector sizes and I've just heard that the wet kit is simply safer then the dry. The reason? I'm not sure. Just what I've been told.
