I needed a guide on how to put a sr20 back in, or perhaps some kind of free videos.. Thanks!!

[-***JOKER***-]

hello guys,

we are putting in a g35 transmissin to our s14. We just purchased the transmission. Now we will get the shaft made but we need some dimensions. Anyone have or know where can i get the dimensions of the g35 shaft head? any help would be much appriciated.

thanks

for sure then. thanks

Will a sentra sr20 fwd o2 sensor fit on a red top sr20det s13?

[NickIsAZero]

I need the part number for S14 Kouki headlight bulbs.

Inner
Outer (projector lense)

Also correct me if I'm wrong, but the inner lights are the brights?

[dahveed]

tanabe pro-sevens. i've got the rears on my S13, and they dont really go that low. the bottom cup thingy(lol) bottoms out really far down the strut, is there any way around that? the 2 rings underneath the coil dont affect ride height?? confuseddd

anybody have some kinda of diagram on how to take off the right passenger side mirror. It is used for a 91 s13 the reason is because it shake while driving on freeway im assuming maybe its loose so ill take it out make it tighter somehow

[Mista Lee]

Is it necessary for me to have a turbo timer even though i'm running coolant lines through my t25?

edit: also, what's the purpose of this can? Any way to delete it?

[Martino]

Charcol canister...used to recirculate gases...totally useless for our already environmentally horrible cars.

Take it out and plug the vac lines.

Simple.

What is the benefit? I'm pretty curious actually. Still effective on an SR?

[pandaroo]

so i sold my coupe and decided to by a cleaner running one lol. i found an add on craigs list for an s13 coupe with a stock sr and by the pics looks pretty clean.

what would you guys pay for it? hes asking 3800.
heres the listing
1989 s13 240sx coupe
thanks in advance!

oh ya...will i pass smog without them in?
thanks in advance zilvia!

I took out my egr and butterflies i didnt notice any torque loss. It might just be me but my car idles fine. And as for the mpg, it chugs up a bit more gas. The only problem I have is my car takes longer to crank on a cold start but once the engine is warm it cranks right up. Im N/A for now but I feel about only a 6hp gain.

and also since you blocked off your egr, it wont pass smog, at all.

[Scorpion34]

Looking to buy an S14 here soon would like to know what I'm getting into. Tried the search feature but didn't have much luck.

Any suggestions on what to look for when looking at one?

I already know they are prone to rust, especially in the rockers. What else do I need to look for in particular?

ya i did it today since i had to replace my gaskets anyways. cant really feel any significant gain. maybe a slight loss in low end, however the power band is more smooth. car is idling fine but i disconnected the battery while i took off the butterflies so my ecu probably reset. i kno that ill fail smog...which is why i just made a blocker plate so i can take it off and my egr will still work. as for the mpg, i guess ill see in a couple weeks.

what are the effects of taking the charcoal canister off?

Heres my understanding of it. The butterflies in there are what allow the intake manifold to act as a dual stage manifold. At low rpm/load you want thinner, longer runners to allow smaller quantities of air to efficiently enter the engine. This provides better throttle response and mileage. At high rpm/load, the ideal setup is shorter, wider runners (hense the greddy intake manifold- short, wide runners). This allows for the most flow at the upper end of the powerband. The idea behind the butterfly valves is to have the "best of both worlds," that is, the benefit of long runners at low rpm, and the benefit of short runners at high rpms. It does work in essence, but some performance is sacraficed on both ends (high and low rpm) in order to have this type of setup. By removing the butterflies, you are removing any performace gain that may have been acquired at low rpm in favor of freeing up the power sacrificed at high rpms. From a practicality point of view- if youre not turbo'd, the meager gains youd experience by removing the butterflies is not worth the noticeable drop in fuel economy. But for a turbo car, the gains can be quite rewarding.

Im gonna start out with some info so people know wth im talking about

a stock s14 ka has 1.75" headers going into a 2.5" downpipe then a 2" exhaust pipe lets say I upgraded my headers to 4-2-1 which is 2.5" which goes into my downpipe thats 2.5" then upgrade my exhaust to 2.5" would I virtually LOSE POWER or torque or gain either of the 2? please PM me with an answer incase I dont catch the reply

[240sx123$]

You wouldnt lose any power. Thatd be basically the ideal setup for an NA KA. Are you sure stock piping is 2"? I want to say its 2.25", but either way, going from a 2.5" to a smaller diameter (bottleneck) will severely hinder flow. You always want your exhaust to step to larger piping, or the same size piping, never smaller.

2.25 might be correct but im certain the headers are 1.75 and downpipe is 2.5 but you think i would gain anything? im a drifter kinda guy so i want my torque

Yeah if youre planning on staying non-turbo and want the best performance that the KA can offer without being turbo, a 2.5" exhaust would be ideal. If youre planning to turbo, youre gonna want a 3", but a 3" would have minimal losses on a stock KA. I ran my stock KA with a 3" exhaust for a year before finally swapping my SR in. The losses were barely noticeable.

1st problem is the gas gause doesnt seem to work any ideas? ive check all the fuses and even replaced them. everything else on the gauge works

2nd is my brake lights turn on but when i pres down on the pedal they dont light up. any sugestions?

does anyone know?

[chiboy002]

for the gauge, take off the cluster and try using a voltometer to check if the gauge works

for the lights, you could have just burned the filaments, or old owner put wrong bulbs in

s13 brake lights are double filament, 1 is for normal parking light and 2nd is for brake

Well I am wanting a ka-t later on.....but the exhaust tip I already bought has a 2.5" inlet and it was hard enough finding the style of it cause I'm not a n1 tip fan....

is there a way to adjust zenki headlight if the adjustment screws dont work ???

What losses? Can you back this up?

You can still go turbo with a 2.5" exhaust, but your power goals will be limited by it. If you already purchased the exhaust, dont sweat it. Run it, keep it on there until youre turbo'd, and upgrade it when it becomes a limiting factor again. For the time being, youre fine.

Well its debated- Im sure you know this. Are you baiting me into an argument about a 3" exhaust on an NA KA?

Haha just kidding. There is some reasoning behind the fact that TOO BIG of an exhaust piping diameter will cause a loss of power or throttle response at lower RPM's. There is also a fair amount of support that suggests that losses from 3" piping on an NA KA are minimal. I cant say that, after putting a 3" exhaust on my NA KA, that neither theory is 100% correct. Granted, I never went to the dyno, but Im fairly confident that I felt a slight drop off around 2-3k rpm, and a fair improvement above 4500. Thats not to say every car isnt different, but by and large I feel that my car is AS FAST as it was with a stock exhaust. Not slower, nor faster. Just louder.

I've dynoed it on the same car with same mods other then the exhaust change. The graph has been posted many times on the forum.

So basically what youre saying to me is "not uh, youre wrong."

Why not just say that?

Why try to bait me into giving the answer that you thought Id give, only to shoot it down, when you clearly knew the answer all along? Were all adults here, I dont think the childish games are really necessary. If you know the answer to a question, answer it. If you have something to add to someones answer, add it. But dont belittle the poster simply because their answer wasnt "up to par" with your standards. If you have a better answer- were all ears. Simply posting "not uh, youre wrong, ive dynoed it" isnt helping anybody. Rather than being rude, wouldnt it have just been easier to post said dyno graph?

No response to this is necessary, I just thought Id point out how unhelpful your line of thinking is, not only to the person asking the question, but to anyone who may be browsing the forum.

To keep things on topic:
What is the name of the black metal bracket that is bolted to the top of the bumper support and runs across the width of the car? The bracket that the bumper cover bolts to. And is that part the same between zenkis and koukis?
