Nitrous *Project Now Complete*

[Wasso]

Hi, to all those techy Z owners or mechanics out there. I am a fairly new owner and I have owned my 2006 (300bhp) Zed for about 3 months now. I was massively happy with the power when I purchased it, although now feel that some additional power gains are required. I have already been to a specialist garage who look after serious modifications and I was quoted £10k for a turbo, which I believe included additional engine modifications to take on the turbo.

 

Since a recent visit to the Jap Show at Santa Pod, I was intrigued to see the vast number of cars using Nitrous. My initial thoughts towards Nitrous were cautious, as I understand great care and attention is required for the install and for the setup/maintenance to ensure detonation is avoided. I have reviewed the Wizards of Nos website who have a system which bolts on to manage the flow and power of Nos required, right down to a 10th of a second, which sounds impressive.

 

Using Nitrous I see as a massive cost saving against the turbo, although I still have doubts. What is your opinion of applying Nitrous for street use, with occasional quarter mile runs now and again (not for serious competition).

 

My questions are:

 

Will I kill the car! (important question)

Is there a preferred system for the Nissan?

Is it wise to install a management system / and which type to avoid detonation?

What other engine modifications should I consider to work alongside Nitrous?

 

I have already set my first milestone at getting the air intake and de-cat exhaust sorted. I was recommended to have a custom built de-cat solution at a cost of £450. I was advised that some distributors claim to have de-cat systems, although they are not totally 100% de-cat?? Advice on which systems would be helpful.

 

Budget for modifications is £3,000, which I am sure is plenty, although I would like to change the SatNav screen for a normal monitor, so that I can then install a DVD player, or E-pc, Netbook for some funky nitrous software/engine management display/information data?

 

I would be happy to claw 450bhp with my budget, although I am sure your comments will clarify if this is at all possible.

 

Cheers

As I'm a bit of a HP junky and like to be kicked back into my seat I had a quick google and found this article:

 

http://www.turbomagazine.com/tech/0409t ... index.html

 

Kinda explains it pretty well I think. Not sure about it though, read here from website selling the stuff:

 

http://www.edelbrock.com/sportcompact_n ... _dry.shtml

 

Can't see that there are any engine managment system included and would think that you would want to have one (to get that perfect tune) Would be cool to have one though! You going to be the 1st on here? (stand corrected; 3rd)

 

450bhp = not sure the internals will like that on the Z

 

Mine started at 265 (fly) and now has 318 (fly) only thing left for me to do to gain more power would be FI & or upgrade the internals. Then again the latest dyno was done on the wheel (Where it acutally counts) so maybe I could change something alon the power train to not loose so many ponies on the way to the rear. As for 3k... I've used up a bit more then that I think with all the tunes and the engine management system. (did most of the installs myself to save some dosh)

 

Best of luck and if you go down the nitro route let me know how you get on!

 

 

Some notes from another site:

http://www.350z-tech.com/forums/index.p ... topic=2333

I think 3 grand to achieve 450bhp is seriously ambitious to be honest.... Infact you could quite easily spend that on a decent full exhast system, CAI and engine management which is unlikely to take you beyond 350

 

Some more experienced members will be along shortly I'd be surprised if anyone has achieved 450bhp on a normally aspirated engine.....I know that nitrous could temporarily deliver a 100bhpshot in theory, effectively giving you 400bhp but I cant imagine it would be long before the engine went bang

[Stew]

Certainly won't be the first on here.

 

P15UL T and Zedrush both did Nitrous. Zedrush got (and posted) some good stuff on nitrous on here.

 

450 on standard internals is a quick way to go bang! Not sure what of 'shot' the standard internals will take although the budget is probably plenty healthy!

[maxi-glasgow]

Have I not read on here with regards to FI that the OEM internals can handle up to 400BHP, so if you can get 100BHP boost from Nitrous on a 297bph car then it shouldn't have any adverse affects, or am I wrong. Does a nitrous boost put extra pressure on those internals which FI wouldn't?

thanks for the thread link, tried searching for zedrush as member and within that using nos or nitrious but came back with nill... Good read on that thread.

[maxi-glasgow]

That is an extremely informative thread from Zedrush, it's actually got me thinking of doing it now, with the controller and window.....

+1 if I can find someone over here fitting it and I can use my haltech ecu instead of the controller + window setup

[Wasso]

Zed'ers, thanks, great information, especially the informative threads posted by Zedrush. I believe that I will go ahead with the modifications, although will now seriously consider increasing the budget to accomodate strengthening the internals. Has anyone on this forum gone through the internal modification route? What sort of costs are involved? I had a quick browse and found some forged pistons at £799, what further modifications are required on top of this to assist with power over 400bhp?

 

I must admit, I will without a shadow of doubt go for the progressive controller and window switch, I really don't want to suffer any engine issues.

 

Has anyone any further comments de-cating the exhaust, as mentioned, I was advised to have a "hand built" solution which would benefit over any aftermarket product?

 

Again thanks for all your comments, very helpful.

got a quote on between 8k-10k € for that work on mine

 

That was all the labor and parts. From 3.5 to 4.2 and re-tune.

 

parts will land you around: 5200€ delivered to your door. Then xxxxx amount for the work, that depends if you do most yourself or if you know somebody that will fit it for less then 4k? let me know what you decide to do, is your wallet an empty black hole like mine???

It will probably depend on what figures you're looking for, i think the first thing to go is usually the con rods. The hand built de-cats sounds a bit strange as any de-cats i've seen are just a straight bit of pipe.

[Wasso]

Hmmm looks like engine modifications/strengthening are also going to be expensive. I think I am going to go for the 75-100hp increase from the Nitrous (with the progressive controller etc) and hope that nothing goes bang from my very heavy right foot. I can't justify spending £10k on the car, I think next time upon purchasing a car I'll get one with a turbo already installed, i.e. Mits or Scooby? Not that the looks are anywhere near a good as the Nissan, neither is the comfort anything to write home about. I guess if I want a reasonably easy upgrade of an engine to source a car already turbo'd.

 

A great shame, although if I ever windfall any large cash amounts in the next 3 years then I'll definetly go for the full modifications.

 

Thanks all for your comments.

I know they are a little on the chav side. Although what other options are there? Name me a great car, with comfort, i.e. Leather, SatNav, cruise etc, that has a turbo and can be reasonably priced? I can't think of anything?

 

The Zed gives me all the above, although no turbo without shelling out fortunes. Maybe I am just greedy and that 297bhp should be enough, and it's not enough! Although a lot of the power is lost due to the weight of the car. A friend of mine is currently dirving a Civic Type R on a 02 plate. His car is 50 stone lighter than mine, and he's keeping up with me! I need to shake him off good and proper!

[cookiemonster]

Just checked with my insurance company (admiral) and they have said under no circumstances will they insure me with Nitrous.

turbo the yoke mate and you wont need to get another car EVER... 20k and you're set

 

Regarding comfort etc... two of those aren't needed: satnav and cruise There's plenty of other beasts around without going down scooby route... (sub)

There are plenty of insurance companies out there who r fine with nos as long as you state its for track use only and you will take out the necessary insurance on the day. dont think any insurance company will let you have it insured for public road use, not only that I think if caught its not so black and white if its legal. Shows, private roads and tracks are fine, public use is still questionable and not worth the hassel (not to mean you cant have fun but I wont put my name up endorsing it). But for insurance purpose they will be fine as long as you say you have it but is switched of until you track it in which you will get extra insurance for. It is very easy to remove should worst case scenario happens, unless you have direct port into each six cylinders Carry spare induction pipe with you, should you need to quickly swap.

Nos will soon see you loose him... weight is pretty necessary for handleing in all conditions unfortunatly.

 

You may want to look for something like a unichip for help with controlling the Nos...

 

There are a few other owners that have NOS on here too

[Wasso]

Well, I've spoken with Wizards of Nos and they have quoted for a fully fitted system, with window switch and progressive contoller, including all setup for £1500. So plans are to install in the new year, as Nov5 and Dec25 are normally expensive periods of the year for me.

 

A great shame that I don't have endless amounts of excess wedge available to really have a good time. If I did force my extra cash into the car I am sure without hesitation my other half would put a "for sale" sign up on the house . Leaving me a very unhappy chappy. Although at least I'd have a super quick car .

 

With regard to the insurance, I think I will also speak with my insurers to see what they say, and tips to mention the Nos is for track days sounds a pretty good idea. I could also say that the equipment is taken out whilst general driving.

I would only say that to your insurance company if you are taking it all out for day to day road driving. Otherwise you might as well drive with no insurance!

Hi,

 

I have a 100 shot progressive WON setup. I've done alot of the work myself.

 

You can read the build thread here: http://forum.nitrous-advice.org/viewtop ... 63&start=0

If you need any guidance, let me know.

 

WON is DEFINATELY the kit to get IMO mainly because of the unrivalled support that Trev and his team provides. They're one of the most transparent companies I've ever seen.

[Wasso]

Sorry for the late post, thanks for your tips. After speaking with WON they were very helpful, I asked for my requirements, two of which are important - Power and Safety, or is it Safety and Power? Either way I don't want to blow the engine, although at the same time I am looking for some considerable increases to blow away the competitition.

 

I am yet to purchase, due to house moving - although I am in the realms of purchasing a nice ARC induction kit courtesy of JDM Performance.

 

So I guess the bug has started. I will keep you posted and thanks for your comments.

[Wasso]

Aha!! my NOS has arrived! After spending £1,100 on the kit I am dead excited!! Wallet feels a bit lighter, although in the back of the car is my project for the weekend.

 

Looks like I am starting with a 25bhp to start with (advice of Wizards of NOS) upgrading the jets in intervals once I am happy the kit is working to it's potential without hicups!

 

I shall take staged pic's to upload over the weekend.

 

In addition my new plenum spacer received today from Envy Performance will also be added - so it looks like I'll be a mechanic over the weekend - so that's no Modern Warfare 2 for me this weekend

same mate of mine has his type tunes to about 250-260 wiht a few bolt ons , no back seats and up to a tonne hes ahead then it evens out.

put simply though if you want a car that will give the first 70-100 bhp for cheap you need a turbo thenall the mods really do is just wind up the boost.

but if you can afford to boost the Z forget being caught altogther !

[Wasso]

Interesting, you say - my mate is now contemplating NOS himself for the Type R - I think he was more excited about seeing my NOS that me!!

 

I'd really like to review saving some weight too. I've been checking out Titanium Exhausts - expensive I know, but massive weight savings. Not only that but carbon boot lid - not too expensive but def a good investment for saving weight. I'd love to strip my luxuries out the car, but feel that I wouldn't enjoy the car for what it is. If I had the spare cash I'd have a 2nd Z just for moding, but that's not possible.
