Safety Gear:
Fuel Pressure Safety Switch
NGK Plugs (Gapped to .035)
Good set of wires.
Wide open throttle Switch.
RPM Window Switch
Maybe a manual activation button like I have.

One of the most important parts is a good installation.

All the switches will ensure that you are at WOT, above 3000RPM and have enough fuel pressure.

I have pics, but i have a 97.
Good luck if you decide too shoot it! [img]graemlins/thumbsup.gif[/img]

I may want to go with a dry kit, if I can route 2 nozzles on each side of the air lid...

If the 2 nossle set up works what sizes should I order?

Also has anyone done the NOZsle kit from NOS on their car yet?

can some one give a direct list of "safety" parts I should have for my car?

With a dry kit there is no need for two nozzles, unless you are just going for a certain look. The 5175 kit comes with a 47 jet. If you go with two nozzles, you will need to split the difference. Each one should be a little bigger than half, to keep the 85 hp rating. Two 24's would not flow as much as one 47.

I would love to hear about NOSzle too (or however you spell it). Looks like an easy direct port system without having to take the intake off.

Safety parts:
On the bottle end, a blowdown tube connected to the safety release valve.
On the engine end, the fpss, and if you have a manual transmission you should probably have a window switch.

I also have a fuel pressure gauge, and use an autotap to monitor my a/f ratio via the o2 sensor readings, and have a maft to tune with. If you go with the stock jets in the 5175, you probably will not need the autotap or the maft, but I had to know...

I may have a picture of the nitrous setup in the link in my sig. (edit- apparently f-body.net has let their domain name expire, so I guess never mind about the link, until they get it fixed...) I probably have a pic on my pc somewhere.

Is it Very important that I get NGK plugs I've got about 43K on ths stock ones and I guess changing the wires while I'm at it would be good? Also, do many of you guys have autotap, I don't know if I want to deal w/ that. I'll get gauges (i.e fuel pressure, a/f), but would dynoing it after install be fine, making sure the computer is running everything right. Also how do you guys have your computer systems set up, does the MAFT+ help?
thanks
Matt

Most people on here swear by the NGK's. I'm one of the few exceptions. Still running my stock plugs and wires. With 80,000 miles on them... I did regap the plugs to .045 vs. .060 because I had a slight misfire when spraying with the stock jets, but only with the big plug gap.

I went with a bigger shot, and had a slight misfire again. So I bought NGK's recently, but haven't put them on yet. Rejetting my fuel jet, and installing bigger fuel injectors solved my misfire (because I was running a little lean with the bigger shot). So I may not put the NGK's in yet. I'd like to do a before and after, once I finish tuning, and see what difference they make, and see how well the stock plugs are holding up to the bigger shot. The supercharged GTP boys seem to mostly run platinums too, checking another board.

Autotap is not essential. I have it. I mainly use it to monitor a/f ratio for tuning. If you get the a/f gauge you mentioned, you can watch the ratio that way, but it may not be as precise as monitoring the o2 sensor readings with autotap.

With the stock jetting on the 5175, and the stock fuel injectors, I used the maft. I set it to 2% lean na for best performance, and 6% rich when spraying. That was based on o2 readings reported from autotap.

When I drilled out the nos jet to a 100 shot, I had to go to 14% rich when spraying, and it still wasn't quite enough, but it was the max setting.

Then when I put in the 24lb fuel injectors, I had to go the other way, over to 10% lean.

Since then I have drilled the nos jet out just a little more, and need to check where I am now. I will probably install the boost-a-pump before too long, and that may further change things.

So the maft has worked out well for me, with the various changes and tweaks I've been making to the car.

**Badv6** · 09-25-2002, 10:08 AM

How do you control your settings for the maft John? I want to be able to control everything from my driver's seat? Is this possible? Also I guess I'll get the NGK's what model and gapping sohuld I get? Does anyone know of a good place to pick these things up at? Also what wires do you guys run with?
Or is it just easier to get an MSD dis-4?

NOS 5175 is designed for a stock ignition, you don't need an MSD. You don't actually NEED NGK plugs, but why would you want to chance it? You know that nitrous isn't safe, so why cut corners?
Get NGK TR6 Plugs, gapped to .035 and most people run the Taylor Spiro Pro wires because they cost less than other brands. Beware that the total cost of getting you car n2o equipped safetly is more than you would guess. The plugs cost money the wires are about $50, etc. This is just one of those things when you don't want to be cheap about it, or lazy. If you think changing the plugs is a lot of work, how about walking everywhere you go?

BTW, the NOSZle i believe is for a wet kit, if you want to go dry, then you can't use it.

The maft instructions say the car has to be turned off when making changes. I would love to be able to change it from inside the car, especially since I change the settings when I switch between nitrous and n/a. But the turning off the car part would make it kind of a pain.

The box comes with two cables, about a foot and a half each. You unplug the stock cable from maf sensor, and then plug it onto one of the cables from the maft box. Then you plug the other cable from the maft back onto your maf sensor. It basically just splices into your maf cable, using the same style connectors.

To change the settings, you take the cover off the box, and turn a teeny little dial (about 1/4" dial) with a teeny little screwdriver in the slot in the top of the dial.

Can you route 2 lines, sure. It seems to work quite well for a good spray pattern and cooling effect on the newer style intake set up.
What size, just check with nos tech line. 47 jet? That might be it. I don't remember that hp level :D
NOSzles, this is a poor mans direct port system. It is not a true direct port system. It is way too expensive!!! It is cheaper to just get a direct port system. I do not know anyone who has this set up. I did not like the look of it. I would get direct port instead.
Search for safety precautions.
I've listed them all.

I'm a fan of the ngk tr6's. They have worked very well for me. They are 2 ranges colder than stock and gap them at 0.035. I know some people run stock heat ranged plugs regapped but that isn't for me. If it works for them more power to them.
No platinum plugs, they do not work well.
Keep stock injectors. If you go bigger you need to send out your computer for tuning. Sure you can install bigger injectors and yes they will work. The pulse will be different and top end it will run lean, how do I know? I already tried accel 24 pound injectors and I'm on my second engine.
Please do not drill out jets, I'm not a fan of that either.
John, please do not think I am bashing you in any way. I am just scrolling down this post and replying to whatever I see. What he has done works well for him. I know what has worked well for me. The best thing to do is sit back and learn all the ways to make a better nitroused car. I encourage all feedback here. He has experience with the maft translator, I have none. He is smart with tuning with the autotap and maft. I plan on moving in that direction soon.

No problemo...

A lot of the stuff I have done is more advanced, and is probably not good for somebody new to do. With porting the throttle body, going with a different year maf sensor, changing injectors, resizing jets on the nitrous and the bypass side, maft tuning, it's a lot of stuff to throw into the equation.

And I am kind of "out there", when it comes to the plugs and injectors and stuff too, the renegade of the bunch, going against the flow. [img]smile.gif[/img] Gotta be different, gotta find out for myself.

The real test will be when I'm done tuning, and see where the e.t.'s fall. And see how durable everything is after racking up a bunch more runs. Four bottles is a good start, but there needs to be a lot more. I'm curious what I will pull without any head/cam/converter mods and still on stock tires too.

So yes, to anyone who is thinking about following any of the stuff I did, it should probably be considered experimental, and is definitely contrary to popular opinion, and should not be taken as a recommendation for just starting out...

Cool man.
Best of luck also.
Who knows, you might stumble onto something that becomes the norm for nitrous peeps in the future
