I was wondering if anyone was using NOS with over 100k on their max? I have just hit 132k and have nothing to say bad about my car. Would this kill my max?

am still debating it, its so cheap! i have 95k or so on my car, lots of people told me it won't do much more harm unless i use it everyday.

Two words, compression test. If you're in the specs, spray away!

how to do a compression test myself but nissan dealership said they wouldn't even bother doin one for me cause its a waste of money cause they know my car is in good condition, good friends with the service guy Karl considering i have gone for lots of my mods.(suspension,exhaust,brakes)never knew the dealership would do it for me, maybe not as cheap as other places but if they screw up they garaunteed me they would fix the problem

A compression test is very easy to do. What you do is save up $15 dollars and go to your local Pepboys{Or significant other} and buy a Compression guage, the instructions are very easy and straight forward. In short you just have to remove all your spark plugs and screw the guage into each spark plug{one at a time} and then crank your car for 5 seconds, then go out and look at the reading on ther guage. FYI, my car had 168 PSI compression all the way around= Perfect

if you guys want nitrous let me know....i am wholesale distributor for NX, which in my opinion is the best kit out there. it's a wet kit and it makes more power and a lot more torque than NOS.

Find me a price on an NX kit or NOS kit and i will beat the price.

bosco500

what is the difference between wet and dry kit?
is it a big price difference?

Where were ya about a month ago.
I believe at least 4 or 5 people have already bought the NOS dry kit from JCWhitney.com for $375 delivered.
Since this is the kit most discussed and used on this board it seems to provide a level of security and support for new NOS users.

i'm just not comfortable running a dry setup.

i know it can be done but for the price (an extra $75-$100) you can run a wet kit.

a small 50 on the maxima will not be bad with a dry shot but if you want to get bigger you should definetly go with a wet kit, which is the only kit that NX offers.

Single nozzle wet systems on the "L" shaped intake manifold on the 4th and 5th gen Max's are not advisable. The Intake runners are designed to flow air not fuel. This will cause un even fuel distribution and may cause serious problems. A "profogger" or nozzle per cylinder system is the best to use but it can be more expensive than the single nozzle.
I dont know of any one who has ever run a single nozzle wet system on a 4th or 5th gen?

Most use the Nitrous Oxide Systems (NOS) dry kit. Their are quite a few people here who use it on their 4th gens. It has proven to be very reliable. My self and SXR7 both run 100hp jetting and have not had any problems.

cool!
i learn something new everyday.
the wet kit is on my maxima but i never use it.
it's just for show. maybe i will run it some day and see if i can blow up my engine.

thanks for the info.

I wanted to do a single nozzle wet kit too, I had the parts and its much cheeper and easier to tune. I talked to NOS teck support and they advised against it. I then called the frieldly folks at SGP their in Houston and they confirmed that the single wet nozzle system on a motor with a "L" shaped intake is not a good idea.

I want NOS NOW

I have been wondering this same thing for awhile. My engine has 140,000+ miles and I figured forced induction would kill my engine before I'm ready to get rid of the car. Even if the car shows good compression, with that many miles surely something will give right? This is a serious question. A blown engine would definitely not be feasible with my wallet, not to mention the headache. It's easy to say "just go for it" but I worry about engine life.

You guys run a dual stage NOS setup, correct? What is the cost of the systemsa you have? I'm looking to do what you have. Did you guys do it with one installation, or did you have the 60 shot and add the 40 shot at a later date? What is a viable weekend warrior with mechanical knowledge estimate on time? Sorry for all the questions.

I run a straight 100hp shot. Whorked up from the basic 5177 NOS kit over a year or so of ocasional tinkering. To install the basic kit, less then a day. To tune it, a few more days.

Frezny

So what did it cost you? I know Thomas uses the 60/40. Are there any advantages of doing one over the other?

I had most of the parts for the basic set up off and old NOS system that was on my old car.

Figure like this...
$400 5177 kit
$120 High Flow Walbro Fuel Pump
$70 Autometer Fuel pressure gauge
$230 Apexi electronic EGT Gauge (Autometer is much less $$)
$40 Window switch
$50 A/F Gauge
$20 Autometer Gauge Pod
$120 NOS Bottle Heater
$100 for misc items like jets, wire etc..
----------------------------------------
$1150 total

I also added an adjustable fuel pressure regulator $160, you may not need this. Thomas doesnt use it. The 60/40 set up like Thomas has is easier on the drive train and traction. I have a stock clutch and it slips with the 100 shot.

To do the dual stage set up you would need
$40 another window switch
$70 a second nitrous solinoid
$50 in misc parts and hoses

Some folks also go for the purge kit wich is about $120.

Frezny

Thanks, MGM. I think I would like to do the 60/40. Auto Tranny doesn't need any more work for now and rough $1200 estimate sounds way better than the $4000 SC cost and time.

The cost difference is $2800. At $3.50 per lb of nitrous that will give you 80 bottle refills.
