hi, i have some questions ...... i hope to help me.
i substitude the "air temp sensor(air box)" with a resistor (resistencia) of 3.3 kohms and it seems to be more power.
how do i to improve more power with a resistor? can i connect a resistor in the maf? can i connect a resistor in the temp sensor?
if yes, how i do ?
thanks.
more power with resistor. help

first off, you shouldnt really do the "intake air temperature sensor replaced with resistor" mod.
your fooling the ECU into thinking that the air is not as dense as it really is, causing the air fuel mixture to lean out.
you going to gain some power, but your also removing some saftey margin.
the maf works on a different principle than the IAT sensor. do not attempt to place a resistor on any other components. your risking engine damage.
in your attempt to gain cheap power, your going to blow your motor.

I think my reply about him ghetto modding his ride is pretty ricey got deleted. I had suggested that he go on ebay and order that little turbine noise maker u stick in your muffler and get some "type R" emblems.
My point being that import drivers get a bad rap as being stupid kids. Guys doing stupid things like trying to do stupid things with their engines is where that rap comes from. It reminds me of the time a ricer was asking me how many valves my car had. (he was in a 16v focus and probably thought that's how many cylinders he had).
If you want some cheap power, get an intake. It'll give your car a little more pep and sound better when u step on it. You get what you pay for.
People, avoid the rice. Really.

And i suppose that makes 'TXmike" the be all, end all on engine performance. Mike, dont tell maik21 about sh*t you dont even understand. Putting an intake on your car and not modding your exhaust is not going to do anything for him noticably except make the revs louder.
Dont listen to TXmike, listen to IvoryJ30t on this one, he actually proven his knowledge more than this newbie.

Such anger. Tsk Tsk. Look if the guy is trying to go cheap, he probably doesn't have a big enough piggy bank to go drop cash on a decent set of headers and exhaust. SOOOoooo...since an intake is relatively cheap and easy to install, it might be something that the resistor guy can actually afford and do.
Sure, you could tell me that if I want real power instead of wasting my $$ on an intake and exhuast I should have just dropped in an SR with a T28 upgrade, but hey, lets get back to reality. That isn't in my price range right now, not to mention that I'm working on handling 1st.
You can tell me that adding an intake will not add any pep to your motor without an exhaust also, hmmm, Ok, but you would be wrong.
I like an angry kiddo calling me a "newbie" becuase my message count is low. Oh, yeah, not only am I new, but I can't drive either, and my car's junk. Yeah.
Bottom line, instead of playing with a resistor for .5-1 hp, put an intake on and get 3-5. Cash left over, throw on an exhaust and or headers for another 10-15+

Brother, if you swapped the cat and added a decent muffler, you picked up some power. For a good intake with a large HKS style filter that won't trip your check engine light go here: http://projectsilvia.com . They're based out of Dallas, but are 240sx freaks. The main man drives a 350z as his daily driver and saves his peaked and tweaked s14 for "special" occasions and the number two guy DRIFTS an AUTOMATIC s13 coupe. They can help you out with quality parts.
Don't play with resistors or "cheapy special" parts. You get what you pay for and you'll be better off with a well tuned car using good parts than gizmos.

I only call you a newbie because you are one. You take offense because you yourself know the proper order to mod your car and are informing others how to "cut corners" and saying there will be a performance increase that is felt. Dynoed, an intake for a KA engine makes about 7 hp total in cold weather. Thats 1 percent of your total horsepower for every 10 degrees below ambient temp. It wont even help your time at all...

I gaurantee you that "placebo effect" alone will make the car "faster" with something that looks good under the hood and increases engine response. Besides, the guy was asking about sticking resisors on his motor, I still say a simple intake is a couple steps up from that and at least heading in the right direction. Apparently this cat has done some other stuff with his exhaust, but even if he hadn't, everybody has to start somewhere. (and an intake is about the cheapest place to start)

spec is right about 18deg, with 93 octane, you could prob do 17 without knocking, but not sure it really do much for you other than cost you more in fuel. Unless you've done stuff to the engine, 89 octane should do ok and save you 10cents a gallon and not really cost you anything in performance. BUT if you're of the "every little bit helps" thinking, than you can try it.
You can switch to Royal Purple (about $5/quart at O'rielly auto parts) and actually gain 1-2 hp due to less friction. (oh, and 2BN-s13, before you say something about that, I'm quoting from a dyno test in Tuner Performance Reports).
