Need some advice please.

Alright,first of all i just got my hotshot header and hks hiper exhaust today,and i was drooling for a long time.

Anyway,i read in a few threads that the hotshot header shows up a blinking light after install,what's the deal with that?I don't mind a blining light.

Also the HKS hiper is fukin HUGE.What's the deal with that?The muffler is bigger then a rocket booster,that gonna sound good?

Here's another one i'd like to know.People always talk about passing emissions,how does it get to that?Do i have to pass emissions at a certain time?No one i know had to ever pass emissions.

Thanks for any info.Yeah i did use the search but couldn't find the threads again.Sorry.

[Structure240sx]

you didnt search too long but i just got down ripping on someone for it so ill help u out. the 2 previous generation hoshots had problems thats why there is a third generation the one i have on my car. as long as u bought the newest one you wont have a check engine light unless u screw up the install.

the hks hiper is 3" right most performance exhaust are thats jsut the way it is. depends what u thik sounds good i've heard alot of people liking it.

as for passing emission everyone does when u get ur car inspected. they test ur exhuast. the hotshot, at least for the s14's, removes the cat so you wont pass emissions with out moving around the o2 sensors from what i read on another thread not so long ago. my uncles shop does inspections i think or knows people so ill be ok i hope.

[Jaegermeister2k]

I think i have the newest header,it has 3 o2 sensor holes,as for the hks hiper it sais it's 65mm which is around 2 1/2",but i measured it and it seems to be only 2 1/4" but i'm talkin about the muffler.The tip of the muffler is HUGE.

So will i have to pass emissions if i don't want to?

[Jaegermeister2k]

The header came with a head gastek,but the instruction manual sais i need to buy a new one.In another thread i read that enjukuracing sent that gasket,and not hotshot,so can i use that one that came with it?I took some pictures of it,seems awefully thin.

[Jaegermeister2k]

Another picture.

[nismofan14]

Hotshot doesnt send gaskets.....that one looks rite though. If you prefer a different type or brand go to the autoparts store nearest you. By the way, it has 2 O2 sensor holes the other is for the EGR line.

[Jaegermeister2k]

Well i put it all in today,the check engine light did come on but i'm not bothered by it,i started the car without the exhaust and just the header,and it sounded like a truck but then i put the exhaust in too,and it sounded really nice.Anyway the sound is great,but i don't notice much HP gains,I noticed way more after i installed the intake a long time ago,now i have header and exhaust and it's really just minimal.Could i have done something wrong?

[yellow_jacket]

I'm pretty sure that if the check engine light is on the computer kicks into a safe mode and no longer adjusts the mixture. This will account for lower fuel economy and probably lower power gains. Someone else may know more about this though.

[Jaegermeister2k]

I read around the board and it seems like it doesn't afftect performance at all,but it might e.I don't see how this could be fixed though.Unless i get a new chip for the car.

[PabloHoney]

clear the code and see if it comes back. If that doesn't fix it then you have other problems I would imagine.

[Jaegermeister2k]

Clear the code?How do i do that?

[Structure240sx]

search on how to reset the ecu im too lazy makes sure u got everything hooked up right maybe one of ur O2 sensors is screwed up. i noticed the biggest difference with the header

[Jaegermeister2k]

I did search and i found out how to look up the error code,and it flashes 3 times slowly,and 3 time quickly,which is 33,and i found out that error code means that the first o2 sensor is malfunctioning.I gotta try to fix it somehow,but i gotta wait till it cools down.Any other advice?

[Jaegermeister2k]

I tried resetting the ecu but it won't.If i turn the car on right after resetting it,the engine light is off but comes on after i accelerate,then it comes off at idle and comes on again,then when i turn the car off and on again the engine light stays turned on constantly again.Any help?

when you do your o2 sensor just don't touch the end, the grease from your fingers can shorten the life of it greatly

[Nismo_Freak]

Take out the 02 ... look inside the little slit and see if the ceramic "pill" inside is still intact. If its busted you need to get another one. On the S14 there is no timing retard or mixture change since the car will switch to using the secondary 02 from what I understand. You should notice the gain from 4000+ rpm. I noticed the motor pulled more up top with my install. All I have is intake, header, exhaust, and fuel pressure regulator.

[Jaegermeister2k]

Only time i touched it i had gloves on,but that was after the problems.Anyone know where i could buy one?And how much they cost?

[yellow_jacket]

What year is this car? Did you take a cat out that was between the two O2 sensors?

So since i also have an s14 i should not experiance weaird fuel mixtures,and the check engine light shouldn't affect performance then,right?I also can't see inside the sensor.

It's a 95,and the cat that was there is actually just a hollow pipe,and i had to leave it in because the exhaust wouldn't fit if i didn't.

[Nismo_Freak]

That hollow cat is a resonator. 02 Sensors are around 60 bucks for our cars.

Yellow, the removal of the cat wont give a primary 02 sensor failure.

Jaeger if you cant see in the 02 you might want to clean it out. Get some Gumout Carb Cleaner and spray it in there. Its safe to use on the 02s.

Will do,thanks man.But that doesnt explain the fact that i didn't have that problem before i installed the header and exhaust.I saw smoke come out on the sensor but that was probably the WD-40 i used for the screw.

No... MOST states do not have emissions testing. Sucks to be you.

[yellow_jacket]

When I put a header on my 97 civic it set off a primary O2 sensor failure. Of course that was a honda and the cat was in the header.

Just go to NAPA or the dealership and get a new O2 sensor and see if that solves your problem. Or if you are really ambitious check the resistance across the heating element, the voltage supplied to the heating element, and the output of the O2 sensor.

[Jaegermeister2k]

Hmmmm?I started the car up yesterday and the check engine light went off,and it stayed off since then.The lamp is still working since it comes on when you put the key on the on position,but it goes off after that like normal.Cool...I guess.
