I bought a normally aspirated 300 recently.

 

The roads have been pretty slippery so it seems plenty quick enough. But maybe one day I'll want more power.

 

I realise turboing it would cost what... £4K maybe?

But I reckon nitrous would be more like £1K.

 

Does anyone know if it's been done?

can the engine and gearbox handle the extra power ok?

 

Cheers folk

 

:dance:

Sll it and buy a TT.

Otherwise........ Jock has nitrous on his NA.... and he's a tight fisted scot, so it probably only costs about 37p

LMAO!! :D

 

has he actually got it working yet tho??

The usual route is exhaust, induction, ecu. These are the easiest to do and reasonably cheep. (you will have probs finding an ecu chip for an NA tho ) from then on depends how far want to go money and work wise. lightened underdrive pulley, headers, polished and ported head, racing cams, all thoese add power but cost some and involve a fair bit of work in ascending order.

 

The reason I went for NOS is that it is reasonably cheap, easy(ish) to fit and, if you fit a good kit and stay withing the limits of the engine, doesnt put undue strain on the mechanicals.

 

The 11lb bottle i have is said to last around 60-90 seconds, doesnt sound a lot I know, but factor in this: a reasonably fast car will do a standing 1/4 in 14 secs, Nos is only used at wide open throttle, so that is between 1 1/2 - 2 miles on full tilt Nos and WOT. The problem that i had with the above is that I dont fancy chucking 100bhp/ 200ft/lb of torque through my back wheels at one hit, so am fitting a progressive controller (allowing a preset build up of nos, over a predetermined time) (also its another gadget) this has the benefit of controlling the power and making your nos last longer., the controller cuts in between 30-60% through to 100% over a time of 2-9 seconds, which again is increasing your FT/WOT time.

 

If you are going somewhere like a track, you make sure you have enough gas (an 11lb co2 fire extinguisher has the same fittings as a nos bottle and is a dam site cheaper) if not it is a little surprise for the traffic light grand prix laddos.

Posted the above cos I couldnt be bothered typing out the relevant bits. Around the 1k mark is about right for nos, if you buy it brand new, look on Ebay, get the kit for about 400, the controller mentioned above, new, cost about 300, so it can be done cheaper.

 

Have had mine working twice, and removed it twice cos i wasnt happy with it, now in its third reincarnation

jock,

whats the 0-60 time of it now?

I have no idea , but is it quicker than a TT now?

I would guess yes.

If you're going to fit Nos, remember it's only good for short bursts. True, it can be used for longer but that isn't what it's designed for and you will soon be getting through a lot of gas.

 

If you want to put a turbo(s) on it then there will probably be a lot of additional work in terms of loom and other ancilliaries. So it may not be as cheap as you think.

 

As a final option you could put a supercharger. This will give you (depending on set up) maybe aother 100bhp and there is a lot less work involved. It might also make an interesting project to do anyway. As far as chargers are concerned you wont need an intercooler either with that sort of powerr so the whole thing is easier all round. As well as the normal types of charges there is also a new type - "electrocharger", which looks really simple to fit: http://www.alphamaleperformance.com/pages/1/index.htm

 

Think long and hard before you start and now what sort of power you want and how you want to use it before you start anything.

Excuse my ignorance, but how the fook would u supercharge a Z????

 

You'd have to have 2, or 1 and split the output to each bank, which i can't imagine helping power much, and where the fook would it all fit?

Well according to the Z car club of Washington they have one :eek:

When I bought my NA I started out regretting it, as I had said to myself I would ONLY buy a TT, but now I think it was the right decision. It might not be as powerful, but it is fun to drive, in a different way. I (kind of) know what I'm talking about as I have had a TT Soarer for a while at the same time as having the NA zed. The biggest difference I noticed (although this might be an auto/manual thing) was when I put my foot on the pedal in the Soarer, after a little lag getting to 3500rpm it just lept forward and left everything for dust. Anything I was overtaking was a spec on the horizon in seconds. In the manual NA overtaking is not such a feeling of power- I have to work at it, and rev the engine quite a bit. When I was getting used to the car I was reluctant to rev the tits off it, but with some advice from people here, I have become a bit more ready to rev it (after it's suitably warm) and I find that in first and second it doesn't have bags of power, but when I go into third and get up to 5000 or so rpm it really takes off AND has a lovely engine note too.

 

Am I being naive, but does anyone REALLY do over 100 on the road? My zed is NOT a trackday car, so does it really have to do TT speeds? 0-60 is about 7 or so secs in an NA(?) and about 6 in a stock TT (or thereabouts?) so does that kind of difference really matter?

 

I like my NA, no, I LOVE it now and would NEVER sell it. I will have this car when I'm 92, having said that, I am still thinking of getting a TT and having the best of both worlds. Maybe what makes the difference is having a 'reliable'/boring daily driver so you can rest up the 'best' car.

 

Um... has this gone off the point? Oh yes... I would have the NA as it is and enjoy it- is it you that has a 1999 NA? That is a lovely car and doesn't need to be a TT.

Better get two then :cool: :)

Or just connect it before the AFM.

Would it work properly if it's before the afm?

(I don't know what i'm talking about now, just an engineer thinking it through)

 

The air after the supercharger would be hot which i guess would have problems cooling the hot wire well. Also does pressurized air cool proportionately aswell as standard pressure air.

 

Also, how would u drive it?

 

I preffer Fuggles idea of 2, which might as well be situated where the turbos are, and in which case just drop a turbo motor in!

No! Leave the N/A in and sell it and buy a TT. Dont bother with a conversion - its really not worth it - The TT has uprated engine components that the N/A would need to handle the power reliably.

Robtor,

 

I can't comment on Bilky's comments as I don't know the Z engine - he may be right. However, if you're not going to abuse it that much this may not be as big an issue as you might think.

 

Don't put the chargers in front of the afm, this will creat chaos.

 

There will be some heat from the supercharged air but I would guess you can get away with this. Make sure the inlets are ideally situated to prevent hot air being drawn in and also make sure you minimise the heat soak. It's never going to be perfect but I wouldn't go worrying too much about air temp.

is it you that has a 1999 NA? That is a lovely car and doesn't need to be a TT.

 

 

I love it to bits. But everyone I tell I have a 300ZX says: "ooh, isn't that a twin turbo?".

 

Oh well, they also get in, see the mats which say "Fairlady" and piss themselves.

 

I guess I should just ignore them and enjoy the car.

 

Besides, all my mates have Seats, crappy VWs etc so they're in no position to knok my purple monster.

 

 

 

 

:hyper:

they're in no position to knok my purple monster.

 

Surely you're just boasting now! :x:

 

Steve

Craig,

 

Dont do it. I think the N/A rules.

 

I'v said this before and I'll say it again, I love my N/A and drive it every day. Yes I have had a few problems with it, Gearbox, Heater and a water pump but all these TT guyes spend more time talking about when their car is going to be back on the road than they ever do driving them.

 

Yes you can make the N/A a little quicker and I will be adding a few mod's and yes it will have more BHP than a stock TT by the end of June. I'm looking to add 60-70 BHP

by then, the last RR day turned out to be 168 at the wheels, that was stock. So with a 1K spent in the right places who knows??

 

If I dont make it, "So what" it will look and sound just right..

 

Don't put the chargers in front of the afm, this will creat chaos.

Mercedes have their air mass sensor after the supercharger & it seems to run fine!!

 

but i shall phone them & tell them that they are wrong straight away!! :rolleyes: :D

craig david we told you to buy a turbo in the first place. everyone allways wants more power. my mate did the same thing and brought a na poopra now hes gutted when i piss past him

True

But i could't afford a late turbo or even find one for sale and I don't trust myself with an early car.

everyone allways wants more power

Dont mean to get all antagonistic on this, but what a load of Toss. Bottom line is the 300zx NA is a fast car. It isnt as fast as a TT, granted, but it is easier to work on and maintain, I have found it cheaper to insure, there is less systems to go wrong and it is my belief that you can use more of the power of an NA more of the time. I support these beliefs by the fact that I have driven and worked on both.

 

Dont presume that everyone who buys an NA secretly wants a TT, If I wanted a TT, I would buy one. I chose to buy an NA and there isnt a car on this forum I would swap it for

 

Craig, my suggestion to you, is learn to drive the NA (eg, thrash it. Seriously, all the power is high up the revs, much the same as a bike) and as your mate in his TT goes past muse quietly on the fact that you havent got turbos to go pop, you havent got hycas to mess up your handling, you dont need to buy blow off valves, AFR, big intercoolers, boost controllers etc. Yet you still have a fast, beautiful car :) And NA's with an open pipe sound so much better than a TT :dance:

no sorry jock but im not having that so your telling me that

1 you dont want more power

2 na sounds better than a tt

3 hicas messes up the handling

then you tell the kid to thrash his na? who wants to drive round at 6 to 7 grand all day in third gear. as for twin turbos breaking down all the time mine hasent and i dont think my turbos are gonna go pop as i change the oil every 3000 miles and am running standard boost. as for hicas i doubt that nissan would put a system on there cars that would mess up the handling. the only valid reason for wanting a na is to save money on insurance and servicing etc. why else would you want to buy a car that looks a million dollars without the engine to back it up?

sorry if i upset any of you na boys but come on you know you all want a twin turbo

I don't think anyone drives around near the rev limiter in third. You might use it to get speed on, but what speed do you cruise at? Any more than 90? Really? If you want to overtake you might drop gear and rev it, but don't you do that in a TT?

 

Why do many people remove HICAS from their TT? Would you REALLY notice the difference if it wasn't there? (I don't know, I'm asking) Would you notice an improvement even?

 

How much power do you need? My car looks lovely, it's well kept inside, it has enough power. I would like more power, but when does more power just become a pissing contest? Why does someone buy an NA? I had a couple of reasons- the car I saw was just in too good a condition to pass up, but also at the time I thought the performance difference would not be too huge. I drove the NA and liked it, even though I had driven TTs. I thought I had made a mistake, and I'd still like a TT AS WELL as my NA, but I couldn't sell my NA now.

 

If someone said, here have either a 1999 purple NA or a 1991 red TT, I think I'd take the NA. If one was an SWB and the other wasn't, that would be a closer call

In answer, 1) In some cases I would like more power, else why would I look at NOS, that doesnt mean I want a TT 2) Ask anyone who is honest on this forum. An NA with an open pipe has a gorgeous throaty and loud roar, TT's just dont sound as good. 3)If HiCAS didnt mess up your handling, why are there so many mods/ HiCAS restrictors on sale? some people are even looking to buy NA steering pumps in order to remove it from their system completely. I didnt say your turbos are going to blow up, but if you have them, it is not exactly unknown is it? On an NA, its not a problem. I did tell the "kid " to thrash his car, but nowhere did I say that he should ride around at Hi Revs, I said that the power was in the HI Revs, by which I meant that he should allow the car to rev freely ( I have raised my rev limiter, as do most of the tuners who work on NA's) before changing up, thus accessing the power that lies in the upper rev range. And I repeat again that any Zed is a fast car, some are faster, no argument, but none which are running properly and cared for are slow. proof of the pudding, if you like, is that there is less of a gap (RWBHP) between my NA and the "standard" TT's than there is between the "standard" TT's and the guys pushing big power.

 

So, to extrapolate your argument, do we not only "all want a TT", but also all want a 500RWBHP TT? and if so, Why is yours standard? Dont you "want more power"?

this is waaaaaaaaaaaay better than the usual gearbox fights!!! :D
