Hi all, i have been thinking about this mod 4 ages but havent found the right people to talk about it, with a 25 shot of noz, not much power i know but will it cool our engine down, also whats the max we can put through our car safely

Right something i have a bit of experience with....

Loads of cheap systems onb the market at the moment... They're all crap!

The only one i would go for is one with Wizzards of Nos Pulsoids as opposed to Solenoids. These give better controll of the injection volume. and allow you to go proggressive (start with small shot that gradually gets bigger = less strain on engine, clutch and tranny).

a 25 shot you'll hardly even feel. You can safely fit injector jets that are rated for 50% of your stock engines output. However anymore than 50bhp jets will require timing modifications (you might be able to get some electronic gismotry that adjusts the timing automatically) that will cost you BHP when your bottle is empty... which it will be most of the time as a 10lb bottle costs around £50 to fill and will last you around 6 minutes at full throttle (or 60 seconds if you have a purge kit).

 

NX do a nitrous cool charge kit... I'd check that out.

 

I found it to be a big PHAPH and expensive but I'm always skint so in retrospect selling my nitrous prelude and getting a 300zx wasn't such a wise move as the Z32 is by no means as reliable as my old lude but there we go... it's all fun!

cool thx mate for this info, with wizard of noz dont they use plastic hoses and not braided. sounds good though.

 

worth looking into.

Braided hoses look the dogs danglies but are completely overkill unless you're running 400bhp+ setups. Easily replaced if you just want bling from any haudrolyc specialist. I think the newer W.O.N. kits are now using braided. Not sure tho.

so how much would a kit be fitted and with purg kit aswell.

I picked up a Cold Fusion system off ebay. £450 with polished bottle. £75 for a dual purge solenoid. Fitted it myself - easy job done properly in a day. But as i said above... it's a cheap system and is subsequently a load of crap. After lots of experimenting and no noticable boost I eventually got a slight increase in performance running a 30 bhp shot but it was far from a worthwhile increase. Every initial shot would actually cause the car to hesitate. Spent weeks trying to figure out what the problem was and eventually concluded that it was because the initail shot did not contain the right nos/fuel mix as the nos pressure is far higher than the fuel pressure, the nos gets to the combustion mix first. This causes an initial lean burn which could have been fatal for me engine. Wizard pulsoids get around this by putting the regulator jets in the pulsoid outlet where as mine and all the other shite kits put the regulator jets in the fogger nosle that sits about 8" away from the sloenoid. so you have 8" of pipe that the nos and fuel effectively race eachother down to get to the jets. Before the first shot those pipes are empty then after the first shot some fuel is retained by the jet..... I'm rabbiting on now but the one thing that's important here is don't get anyhting unles it has W.O.N. pulsoids (If anyone from W.O.N. is reading this I have a full C.V. that i can forward to you :rofl: )

 

:hyper:

PS put aside about £1500 for kit + pro install + tuning/setup

I have used a wizards of NOS kit, had it fitted to an escort turbo and later bought the extra parts to fit it to the Z. And to tell you the truth it never worked on properly on either car. only ever caused misfire and detonation and before everyone says its my fault i had both cars down to their workshop to have them looked at and they couldnt do anything with it really. I do believe they are good at sticking it on bikes and old carburettored engines like rover V8s which is what they started out doing but i dont think they have a clue with modern injected engines. Remember the consequences are not just the cost of the kit it could be your engine as well.

I would personally use a proper NOS kit lets face it that stuff is used on almost every drag car running in the states right up to those 6 second monsters.

Your choice though bud, just my experiences.

Paul

The info i got on NOS (the original) is they're old technology - havent changed since the 70's, in fact the cold fusion kit i had was "aparently" using re-branded nos solenoids. So maybe steer clear of nitrous all together would be the best advice. I don't know anyone who has/had it and raves about it, except for the people who actually sell the kits!

DaFox I will pick your brains nearer the time .. as i want this for the summer... but wont even tempt myself yet... will killmyself too easily in the winter... so will wait ...

I have had Nos for ages and have had no probs.It is a true NOS Z Specfic Kit that I fitted myself. :hyper: :hyper: :hyper:

hello bud hows you, can you send me info please, many thx mate

I wouldn't go NOS, no experience of it but I am convinced it would lead to premature death of engine. Although you could just install the kit for show and purging at shows?
