Na Fc

Is it possible to push a 87 NA to 200hp? If so what kind of mods do I get to get there?

You can get over 250HP on an N/a engine(FULLY PORTED OUT THE *** AND NOT STREETABLE )

200 at the wheels is a hard number to hit without some good mods. Every aspect of the engine and its systems have to be upgraded and modified to the fullest. Engine porting is probably going to be required also. Full Intake, exhaust, ignition, and engine manegement would take you a long way but you are gonna have to fine tune everything to get to 200 or over.

At the wheels?

It can be done.

It's not cheap though. EMS, port work, etc..

yeah, don't use NOS or you'll damage your manifold, fry your piston rings, and damage the diamondplate floorboard you have.


(happy now? )

That's cool.

Repuatable members say a stock ported Microtec powered N/A 13B will beat a stock S4 TII. I wouldn't be surprised if a ported and modded engine still on a stock ECU would get some pull on one too.

Keep in mind we are talking about a stock S4 TII. If the TII could breathe, it wouldn't be happening.

I have a bit of snail-envy.

Anybody have any torque numbers from a modded N/A? I'd be interested to see if the torque is moving up on the same scale as the rwhp.

Well, NOS is a viable option for anyone who is N/A that wants to see 200+ HPs. The 13B takes really well to wet shots of NOS that are 75 and under.

Oh boy, where to start....

Since WHEN did N2O render a car NON N/A? Did I miss something? Is NOS considered forced induction?

You guys need to get over the whole NAWWWWWS thing. It is a viable tuning option for people who want good reliable cheap power. THATS RIGHT, I said RELIABLE . When NAAAAAWWWS is done right, its cheap, safe, fun, and RELAIBLE. And its STILL N/A.

Nitrous Oxide makes the car not N/a when you use it. Your engine is not NATURALLY ASPIRATED during the spraying.

Ive never heard of different classes for N/A, and FI. At least not in the street categories. But whatever. I am not here to argue the finer points of what is N/A and what isnt.

Fact of the matter is, and Santiago touched on it, the engine is still N/A. He wants 200 HPs out of an N/A motor. N2O is one such method to attain that goal.

I don't know where you guys get these silly ideas, but in the automotive world the term natually aspirated means the engine does not use forced induction. No turbocharger, no supercharger. That is all. It has nothing to do with any chemical additives.

so your telling me I can put a nitrous kit on my car and run at the next drag event as a NA car????

well ****, why didnt i try that before???
I can own everyone. Right now im nipping at the heels of the 350Zs, maybe if I do a 75 shot I can win the whole thing. I guess I could still be NA, from what you guys are saying.

disect the word...

Naturally, meaning normal. IE not aided but anything. Now if there were nitrous oxide NATURALLY in the air we breath you could consider that naturally aspirated. but then of course we would all be high..........





hey thats not a bad Idea

In his sig it says RX-7 SP

SP- I am guessing means street port. Given that he is probably in the 150-180whp range already and most likely he has other bolt on or custom mods.

The Z although has more power also weighs atleast 300 pounds more than the GXL and almost 500 pounds over the Sport and BASE/SE. Given most people that buy the Z are not looking into weight reduction they will probably stay the stock weight for a years to come. Most FC owners do SOME weight redux to help the HP/LBS ratio.

Santiago


I still stand by the fact that Nitrous Oxide(When sprayed into an engine) is not natural aspiration. It is the delivery of a concentrated COMPOUND which has O2 in a significantly higher proportion than the air we breath on a daily basis there for it is not normal and you are adding MORE than the NORMAL amount of O2 into the cumbustion chamber.

That actually makes perfect sense. The bottle is compressed. The compression isn't used just to spray it into the combustion chamber, it's used to send MORE at ONCE.

N/A Nitrous IMO would be an atmospheric charged (no charge) airtight box with only N2O in it. That way the engine would be pulling the N2O in, rather than using the compression of the bottle to spray a higher concentration into the engine.

Right?
