An all out ffa for the #1 HP gain.

which is best for the buck?

First, I'm no expert in this category, but I might be able to answer a few questions...

It is really hard to say one is better than the other because this depends on what kind of setup you make to your car. Just pick NOS for example, you get either a dry, wet or direct-injection system. Where dry/wet system cost less and they'll give you around 70 hp gain, and the direct-injection system obviously cost more, but your hp gain is virtually unlimited. (what I meant here is you can vary your hp gain by adjusting how much NOS will directly fused with your fuel...

Which one is better for your car? I would prolly say Turbocharge/supercharge better than NOS because of its consistency. (notice my uncertainty here :D) But all in all, they're all bad for the engine (shortens their life)

Nitrous will always be the best bang for the buck. I would say that depending on what you wanted outta your car time wise you're prolly lookin' for turbo and then a smaller nos shot for the launch. Personally though your motor will be just fine with any form of FI and NOS, as long as you get the proper mods done to your car at or before the time you choose a form of FI, or NOS. :D Any questions let me know please. :D <IMG SRC="cwm59.gif" border="0">

<IMG SRC="cwm68.gif" border="0"> hi. kind of new to this, i have an LS with 65 shot of NOS, so far i have not had any probs. I only spray , now and then, but learned not to spray off the line at Moroso motor sport, all you do is sit at the line like a fool spinning.. that's when they know it's your first time....

i am farely sure that all NOS does is provide more Oxygen, than what is in air, for the engine to burn. The combustion temperature in the piston is dramatically increased by more burning but the use of NOS decreases overall engine temp. From what i have heard unless NOS pistons are used than using NOS frequently does great harm to the pistons of your car and increases there wear. I am more familiar of it on american cars but I figure it works the same way. Superchargers just force more air into the engine which is why a higher velocity fuel pump is needed (keep air to fuel right) With the more air comes more O therefore more power but since it is not as concentrated I believe it doesnt do as much harm to the engine. But I could be wrong...Just my limited knowledge haha <IMG SRC="cwm55.gif" border="0">

Very good response, I'm also in agreement that NOS works the same in all cars, foreign and domestic. There are different reactions depending on the shot you're doin' to your particular application.

I've just been given moderator here so if anybody has any questions please let me know and I'll be more then happy to help you out with anything you'd like to know. Thank you

Hey guys, I'm about to get a Zex setup for my civic, as it seems the best bang for the buck (I have very low numbers of bucks right now). I plan to get the following:

Zex Kit
NGK Plugs
MSD Window Trigger with pills

That's all I can afford right now. I'll have to run stock timing for awhile. But soon I'll hope to get my hands on a MSD Digital 6.

I don't plan to use it all that much at all (more for the once inawhile street drag and racetrack drag days) so I think I'm okay with my stock clutch.

Any opinions on what else I might want to invest in the future? Oh, and btw, I plan to run 55 shot.

If you plan on squeezing I suggest a new clutch as soon as you can. otherwise for now you should be alright. I always suggest to people though to upgrade their fuel pump, injectors, fuel rail, and get a fuel pressure regulator, along with doin' a msd or other ignition system. this is for 75 shot or higher though so keep that in mind. If there is anything else you'd like to know feel free to ask and I'll be sure to get back to you on it.

from my little knowledge:

SC i think is best for ur car. it doesnt increase overall engine temperature as much as a TC will do. If the timing is right and everything is done right, engine would last longer than any other FI app.

TC has more power, but increases engine temp like hell.. also hear that if the compression ratio is high, then TC is not the way to go? (heard something about the compression ratio with that matter)

NOS is most flexible in that you decide how much power u want. but if u dont know wut ur doing, u can ruin ur car fast. also the engine tends to break down faster.

my opinion for money and power, especially if u have a civic is the JRSC (jackson racing supercharger). i think that is the best imho

Very true, but youre thinking of a lean situation. When most people add NOS, or some kinda charger, they usually upgrade their fuel system. Increasing the fuel richens it all up bringing the temperature back down to tolerable levels, so in essence, the burn problem is solveable.

I think, in the long run NO2 is actually more expensive (if you run often for years), cuz you gotta recharge the bottle :)
I think its actually safer to run NO2 on a equally prepped engine, for it doesnt significantly add to compression and isnt used nearly as much as turbo. With that said, its dinner time!

yes i also agree with member #13
what nos actually does is increase the level of oxygen in the engine when you hit the trigger. But from experience nos should not be used by itself. it is necessary to have many other mods before adding the laughing gas to your car. If anything i would suggest a superchager, it is less maintence than a turbo (i.e. intercooler, wastegate, turbo timer) and is more efficient at creating torque than a turbo, which we all know most imports could use a little more torque. <IMG SRC="cwm55.gif" border="0">

I am not a fan of the supercharger...but this could also be because I have not supercharged a car either. I'm partial to nitrous, but should be doin' a turbo on an 89 RX-7 real soon, just for fun anyways. But like I said before, NOS is the best HP adder for the buck. <IMG SRC="cwm59.gif" border="0">

A real Nitrous kit down't just add more O2 to the engine. It increases the fuel flow as well. Otherwise, it wouldn't have much of an effect. Granted nitrous will make you run a little hotter, but it does the same thing as any other kind of forced induction. Nitrous is just a chemical means of doing it.

Maybe I'm misinterpreting what you're trying to say, but you're severly mis-informed if you think that the reaction is different depending on the shot. The reaction is the same. With the application of heat, it degrades to O2 and N2. The shot size merely moderates the flow rate.

I might suggest investing in some octane booster if you're going to be running the stock timing. I have a Zex kit in my RX-7, and it detonated badly when i first hooked it up. Granted your engine is quite different than mine, but i would keep a close ear on your engine for a while.

Yeah I think you did misunderstand me. I was just simply sayin' that the bigger the shot the faster you go...plain and simple. <IMG SRC="cwm50.gif" border="0">

Zex is a wonderful dry system to run with, with minimul problems. It is safe and if you have any q's please ask.
