I'm New Here And I have A Simple Question Thread, (No Flaming Allowed)

[brkn240]

Hey man, I just got certified in A/C repair. You may NEED to take it to a shop to get it done right. I'm not sure if these cars are orifice tube or thermastatic expansion valve systems, but it sounds kinda like after 18 years, something's probably gummed up. It may just be low on freon, but if it is, it had to leave somewhere. The o rings are pretty good at drying up and not sealing as well over time. If you take it to a shop, they'll be able to vacuum out the remaining freon in the system, then open it up to check/change the o rings and orifice tube. Although it isn't needed, you should also think about replacing the accumulator. There's a little desecant bag in it that absorbes any moistier that may get in there (moistier is death to your compressor, as water cannot be compressed). Anyway, that desecant bag may be pretty old and wore out, too. If you go to walmart and get a couple cans of freon and the cheap recharge kit, you can really run the risk of over filling the system. Plus if you've got a leak, it won't matter. My advice is to take it to a shop. Yeah, it may be expensive, but since you don't know what you're doing and/or don't have the equiptment neccisary to work on the A/C, I wouldn't suggest this as a DIY fix.

Ok, i just got a 1992 240sx se Automatic. I just wanted to see what the first thing i should do to it. Maybe shocks?

[PapaSmurf2k3]

Does it need anything? Is it leaking anything, any odd running problems? First thing to do would probably be a damn good wash and wax. Clean the interior, and engine bay. After that, I'd be doing a 5 speed swap for sure.

[2ndnissan]

I KNOW someone's gonna tell you the first thing is to swap it for a 5 speed!Just do regular maintennance to it to begin with and get a feel for how it handles. congrats on the new 240!Coupe or hatch?

[jonny_s13]

Its a hatch

[jonny_s13]

The only minor thing it needs is a window washer fluid container but thats not going to be a big deal.

How much boost is a stock S15 T28 actuator sent to?

[[S]eraph]

Hey newbie here, I had previously been building and tuning hondas since 98. And recently I saw the light and have converted to nissan. All praise the 240. I have a 1997 240sx LE and I need to know what coilovers to get for it. If it was a honda I would have already ordered skunk 2, but as I said I have seen the light. Yet I have no clue what kind of coilover to get. I am looking for something well rounded. 1/4 mile, drift, and daily driving. I am not so worried about comfort as I am performance but I don't want to feel the tiniest(I think I spelled that wrong)pebble on the groung either. My budget isn't really and issue but I don't want to spend extra for a name either. Something around 1200usd. I have read alot of good things about stance and tien. And I have used tien in hondas before and liked them. I saw good specs for D2 and tanabe as well. But I am still up in the air. A little bit of oppinions and suggestion sent my way would be greatly appreciated. I am going all out with this car and I want to build it right. And one last thing, the S14 top notch sr20det, how well is the bottom end built for the turbo? What is the max boost stock can handle? What are the best ignition parts(wires, cap and rotor) for these cars? Msd doesnt' seem to make anything for it. And do you need wheel spacers for the z32 caliper conversion when using stock se wheels? If so, what size? Thanks and sorry for the nube questions.

I'd also be interested in any advice concerning suspension/coilovers/etc

[onemad240]

sounds like your in the right direction about coilovers, a good thing to do now is try and ride in others peoples 240s with different coilovers to really get a feel for them...i have stance and am dissatified but thats just me. as far as the sr goes you can proly find the answers pretty quick if you search, try google too cuz i dont know bout that, and the same to the brake question

[onemad240]

is this too advanced for a stock kade? you can see the mark where it originally was, it used to try really hard when it got to 4000 rpm but now it runs great



another question is why is there even an option to advance or retard the timing(in general)? manufactures didn't make engines thinking people would do performance mods right? so why can u adjust the timing and not just have it at one spot as only option?

[Vicious176]

Anyone know who makes this conversion kit? I may have seen it posted here or elsewhere, reguardless, I'm in love with it.

You should probably get a timing light and set it. If it is out that far, it is possible you are off a tooth. If everything runs and feels good though, and you are happy and getting good mileage... well I guess thats all that matters! (Until you try to pass inspection that is hah)

[onemad240]

do u mean the distributor may be off a tooth or the timing chain, cuz i have not done any adjusting or replaced the timing chain?

[jonny_s13]

Ok i have another question.

I'm about to change my oil and i would like to get the best for it. Any suggestions?

[HeckYes]

My question.....how exactly does boost controllers work..

what i konw so far...-turbo spins off the exhaust from the manifold

what im confused about...-not sure how a eletronic device can control somthing thats just physically running itself

i found this article when i was searching and it was way over my head so it didnt help me at all...http://www.splparts.com/doc/tech/EBC.htm also whats a selanoid they are talking about??

[Lorder]

Aights....This is my noob question..Im just about ready to buy a 92 240sx se hatch with the hicas system (not sure if it has the lsd). Car has about 204k miles and motor has about 80k. Everything else is stock. I test drove it and nothing seems to bad. Except that the shifter was shaking a bit more then i would like it to and so did the motor when i was just going the 25mph roads. I know the car/motor isnt beat up cuss the owner is my co-workers older brother who is like 40. interior/exterior is good enough for a 16 year old car. just passed emissions test and wat not. He is asking $1800 cuss im a friend which i think is a pretty good deal. now adays these things dont go for cheap. the car wil be used most for my DD from work and fishing wat not. I'm planning on lowering it and putting in a short shifter and will see from there. first time driving it compared to my 96 integra ls and my lexus gs 400 it didnt amaze me but im still buying it. just want ur guys thoughts on this... if theres anything i mite of missed that u guys would want to know feel free.....Thanks

[porkchop911]

Im new to the forum as u can tell but i need help with trying to figure out which engine swap i should do with my S13. I was thinking about gettin a RB25det but dont kno how hard its gona b to do. Does anyone have any good advice>

Thanx, Porkchop

[brkn240]

No RB drops right in.

[Pyrokid]

^ He speaks the truth, RB are a labor intensive swap, but if you have the cash, the time, and the skill I'd say go for it. But if this is the first time you've had your head under the hood of a car, stick with the KA for a while.

[PapaSmurf2k3]

I mean the dizzy may be off a tooth. You should either buy a timing light, or take it to someone that has one.

Ok i have another question.

Mobile 1 is good shtuff. Get 5w30 and get the mobile 1 filter as well. Stay the hell away from Fram.

ok, I didn't read the article you posted, but this is how they work. The wastegate is the thing that opens to divert exhaust gasses away from the turbo. It diverts enough away to maintain constant boost pressure. If it isn't big enough, it will not be able to divert enough away, and this is how you get boost creep.

The wastegate gets its "signal" from a vacuum source on the car that sees both vac AND boost. Usually this is the fuel pressure regulator vac. signal. The wastegate begins to open when the pressure in the signal line matches the pressure of the spring that opens the valve (to divert away the gasses). What an electronic boost controller does is inhibit that signal from reaching the wastegate until you have reached your desired boost pressure. After that it lets the wastegate see enough signal to open, and vent the gasses away. Note: you can only regulate pressures UP, meaning if you have an 8psi spring in your wastegate, you can NOT set your electric boost controller to 5psi, and have the turbo operate at 5psi... it will operate at 8.

make sense?

check it for rust. If it has HICAS, it has LSD, unless for some reason it was swapped out. Your motor and transmission mounts might be bad... not a big deal. Post some pics up!

[jonny_s13]

Thanks PapaSmurf2k3

[ISHC]

im thinkin about buyin this 95' from this dude on auto trader he wants like 4 grand for it, but im trying to see what some other people think. 100k miles or so.



heres the link:

[PapaSmurf2k3]

eh, its a little steep. Looks like he has 2 different styles of wheels on it. Its also automatic.

If the interior is uber clean and it runs and drives great with no leaks, then its a decent buy.

[KiMbRoZz]

I wanna turbo my ka, and I am aware that you need to upgrade MAF. Will a SR20 MAF work with my KA motor? let me know!

[ISHC]

i wasn't planning on keeping it automatic, one of my friends dad owns a transmission shop and if can get the tran. he told me he would drop it in and link up the clutch dirt cheap.

other than that i told the guy ive got 3,300 cash and could take it off his hands this week

[Lorder]

Sold my integra today and am waiting to buy the 240. the guy said he recked his other car which i saw when i went to test drive the 240 and wont have another car to commute in if he sold the 240 cuss the other driver didnt have insurance. so it will be a while before i get it DAMMMIT=( so mad at this timing. was waiting so long to sell my integra cuss i had the title changed to my name from my dads name and was waiting for it in the mail. then when i do sell it i cant buy the 240!!!!!!!! Im not happy at the moment but i dont blame him just the timing. i cant wait to DD the 240 lol. will post pix when i get it and maybe get a better digital camera then my 4megs now.

[sil.40]

pop open the flip up lights button. cut the brown wire. there you go. im not gonna tell you how u use it though.

Sounds good.

You only need to upgrade your MAF if you plan on making more than about 250hp at the wheels. If that is the case, you should get an N62 MAF from a 300zx tt. SR20 MAFS will work, but I beleive they max out around the same spot the KA MAFS do.

[KiMbRoZz]

thank you, papasmurf!!

[Drifting10]

so i may be retarted but how do i go about replacing my headlight bulb in my 91 hatch? i tried the other day and couldnt figure out how to get it outta the glass
