Need A Link To A Nitrous Install On A CIS-E Benz Thread Please

I have done an internet search and have only found stupid stuff like questionable YouTube vids of CIS-E cars supposedly equipped with N2O but nothing with actual useful information like the specifics on an actual N2O install on a CIS-E car.

There's even an old thread here on this site from over 13 years ago http://www.peachparts.com/shopforum/performance-paddock/30042-nitrous-300e.html where a mod (300Evil) is trying to procure the same information on the same topic, but he was unsuccessful.

I have so many things on my plate I don't know when or even if I'll ever get around to doing my long dreamed about turbo/CNG install on Benzer5. The outcome of the "Bad 300E" build (in the sticky section) has discouraged me even more. In the meantime driving a low to mid 16 second car is getting profoundly old!!! So I want to do a quick, dirty, and cheap N2O install using a used kit scored from Craig'sList. (No, I haven't "scored" one yet, I figure I should get more info on what I need first.)

Please, SOMEBODY out there has already done this, I just need to see how they did it. I really don't want to blow my 110,000 mile engine trying to learn lessons somebody else has already learned.

To anybody wondering why don't I just do something with one or the other of my M119 cars, I simply have grown too tired of working on them all the time. One won't even start and is in storage; and the other one is sitting with a badly blown trans seal. As I've said before, I don't want to go through the misery of R&Ring that 145,000 mile trans to only just replace the seals when it's likely that the trans probably has less than 20,000 miles left in it anyways. What a nightmare! Frankly, it would be easier to just pull the engine and trans out together and install a freshined 5.0 M119 and a rebuilt trans in their place. But now we are talking about another major project that I just flat don't have time for. Don't have the money for that new powertrain either. Enough said on all that.

So please, let's just put N2O on my daily driver. All I know so far is that I don't dare install a "dry" system, I need to use a "wet" system since it's highly unlikely that CIS-E will be able to properly keep the AFRs in a safe zone when the N2O is activated.

Again, please, all I'm asking for is a link to a thread where somebody has already done this. It would be a plus if the thread is about a CIS-E M103/M104 car, but at this point any CIS-E install would be a help. Thanks!

Regards,
Eric

There is nothing different about putting a wet kit in a cis car. Just put the nozzle under the throttle body. Then you just need to adjust the timing. A timing retard device is simple enough. But to answer your question I have never seen one on a CIS car. Just make sure you have enough fuel supply if you are going to tap off of the stock fuel system. My experience is the dual pumps are good for about 300-350 hp, more if you remove the check valves in the fittings. Put a wide band sensor on it. You can easily run a 75-100 shot if the headgasket is fresh.

Thanks Whipple.

The "under the throttle body" thing is one of the things I don't understand. I take that to mean "after" the throttle body. I'm getting conflicting information on this. Many sources of information are saying to put the fogger before the throttle body. Then there is the CIS air valve to contend with. I'm sure I'd need to put a wet fogger after that because slaming fuel into that plate is going to cause it to separate from the nitrous. Worse yet, it would even cause the fuel to puddle in the intake manifold. But installing the fogger after that plate would be introducing a sudden blast of rapidly evaporating nitrous and fuel immediately under that plate which might disrupt it's action. As sensitive as it is, it might just be forced back up. Even just a little bit of that would spell big trouble for our A/F ratios. I just don't know.

Which fittings are the check valves in?

Think of a nitrous plate on a v8 carb engine. They are all under the carb. You are only going to arm at full throttle anyways. You can go before a throttle plate but you would not want it hitting the air flow sensor plate as you said. As far as pooling you simply do not want to hit it to early in the rpm band so you have high air velocity. Use an rpm window switch for activation with WOT contact. If you were worried about even distribution to the cylinders then you could build a port setup. It is just more expensive and time consuming.
What is really nice is to use a progressive setup so it is not a massive shock in torque. But with a small shot like 50-75 it would not be that big of a deal.

Make sure you drop to a colder spark plug also.

Thanks guys.

I'm still hoping there's a thread out there some where though. I really don't want to be a trail blazer on this one.

The fuel rail,on some engines have a sharcder valve.There's a big nut cap on it.I had a fitting that connected,my gasoline to fuel solienod.I connect to my rear battery with a relay.Ran hot wire to cabin,and back to solienods.I bought a extra pressure valve that shuts down nos if fuel pressure is low.I use the instructions at N.O.S. sniper system for E.F.I.I used same plugs and timing with a 125hp shot.

That reminds me of something. The nitrous kit's fuel solenoid isn't going to be expecting the 65ish pounds of fuel pressure that the CIS systems run. I'm going to have to reduce that somehow. See what I mean about treading into this un-charted territory? I wonder what else there is that we haven't thought of.

You just change the fuel pill according to the fuel pressure. The solenoid will not care about the fuel pressure.

Your fuel injection system runs at only about 43ish pounds which is where most systems run. I probably should try to find a good low mile HFM car myself but it's just so hard to find a 20 year old car with low miles! That's why this 92 was such a major find! Too bad it's not just one year newer. (Cause then it would be a HFM car!)

It seems like this is a bad time of year to be trying to score a good deal on a "used" N2O system. Too many people with too much tax refund money I guess. I remember last November deals were everywhere. I'm taking brand new in the box kits! That's why I like bad economic times. Nobody has any money and stuff is cheap!

I prefer to deal locally. I've had bad experiences with KnappyBay. They were admittedly a long time ago but I still feel too burnt to give them any more chances. Plus I hate Meg Whitman, former CEO of KnappyBay, which still to this day causes me to avoid doing any business with the company. (I hold a grudge for a long time.) Thanks though.

I'll come up with something. In the meantime the biggest problem for me is that I still don't feel like I have all the info I need to do this right.

One thing I need to do is score a M103 intake manifold so I can run gasoline shot through a wet fogger through said intake so I can find the ideal fogger placement for even fuel distribution. I really don't want to try to do an individual port set-up. Remember, this needs to be relatively "quick, dirty, and cheap" or it won't ever get done!

Well the NOS brand Sniper kit is not that expensive new.around $350.I would make sure my fuel pump didn't have to many miles on it.The other brands to me have quality issues.One brand has intergreated solienods. I perfer where you can replace them seperate.Remember better to be rich on mixture than lean.Have fun.I went from stock 17.5 in a 1/4 mi. to 14.67. Beat two v8 mustangs.
