NOS & CL-S -- NSX System
Ok I talked to NOS Systems and they told me to use the NOS Kit for an NSX. Anyone that can confirm that? Someone help me out, don't want to waste money!
Also a quick note - they told me to find out if we have a "vacuum sensitive fuel pressure regulator", so I called my local dealer - Wier Canyon Acura, after talking to a tech they said we don't have one of those. Everything is done electronically. Not trusting them I called up Park Avenue Acura, and got the correct answer. We do have one! - I wish I was on the east coast!!!

Yea, the NSX one would be fine. It is primariy based on the engine displacement. We we both have 3.2L (196 ci for us non-metric compliant people), it would work ouf fine.
They really just supply a generic EFI kit with jets more closely sized to our engine.
As for the statement about a non-vacuum controlled regulator. I certainly would not use that dealer. The idea of using a vacuum controled FPR is to maintain a constant pressure ratio across the inject tip. Without it the fuel mapping would be signifiantly more in depth.
Did those guys ever open the hood or the shop manual and look at the fueling system??

Would you guys recommend Nitrous Expres or NOS Systems? The Nitrous Express system is cheaper by about $75

NOS's EFI kit is a dry system.
Nitrous Express is a single nozzle wet system.
Two different types.
I have no idea how long the intake runners on the CLS are. It's not a good idea to run NX/wet system through long intake runners. Intake runners are made to flow air and not fuel.
NX/wet system works great on 4 cylinders Honda/Acura because they have a very short intake runners. It does very poorly on LT1..etc.
NOS's solenoids are more reliable. NX's accessories are more advance.

Wet means it mixes with the fuel first, dry means it sprays it directly into the intake valve or something? 
Btw, has anyone tried NOS on the higher compression CL-S before? I'm worried.

Wet system means the nozzle sprays fuel and nitrous at the same time. Dry system nozzle only sprays nitrous. There are few different types of wet system. Single nozzle, direct port or plate system. The placement of these nozzle/nozzles is what's different between these wet systems.
Nozzle placement for NOS dry kit and Nitrous Express single nozzle wet kit is the same. You want to put it between the MAF and the throttle body.

No MAF here, The CL uses speed density. Secondly, is a single nozzle wet system were used, problems could certainly come up.
You could get puddling in the plenum end tanks. If you went multiple nozzles wet system. You could plumb into the center plenum chamber and tap directly into the down runners. This would be very effective (might disturb the IMRC flow a bit, not sure though) system by being right above the ports. But complicated to install.
A dry system would be much easier to implement in this case. A single nozzle just after the TB right at the plenum split. I had forgot that NX used a wet system in their basic EFI kits.
NOS then..

I saw a stock CL-S running a 100 shot NOS at Moroso race track. That was his only mod. He ran a 13.6

I would still put the dry nozzle right before the throttle body and not after like you said. What if the soleniod get stuck open? If it's before the throttle body, the throttle plate will limit most of the nitrous from flowing into the engine all at once. The nitrous would just all run out towards the airbox/fiter.

Im sure you already know this... but for everyone else's benefit....- Automobile grade NOS is mixed not pure N2O .. With a sulfur % to discourage "misuse" from pharmaceutical grade N2O...... The reason NOS gives the yellow/brown smoke...... if you blow your tranny or worse a competent mechanic will see the tell-tale signs in the form of anything from scorched/fouled heads, pistons, valves, cats, tips ..-etc...- be wary ..... or very sneaky. lol

But I guess it could be placed prior to the VSA throttle. But that is just rubber hose...

I guess that NOS is the make that everyone is looking at??? What about Zex? Do they make quality stuff???? I was about to buy a zex system, but since I see you guys talking so much about NOS...I may just change my mind.

The other main reason with going with NOS is because the are BIG and have a huge market share - they must be doing something right. Also I got to go down to their West Coast office and check their stuff out. Was alot of fun.
Other than that though NOS, ZEX or Nitrous Express I don't think it matters to much (except that Nitrous Express is a WET system which sucks). Its not like spray N2O into the intake is that complicated.
Also if you want to see what the install actually involves, I scaned a few pages of the instructions.
