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

[venom90s]

I would say if you reuse the stock flanges any pipe that you can weld to it that is lightweight could work, but make sure you know which pipes could be welded to it or not, since some steel/alloys have different melting temperatures.

I'm pretty sure you can buy exhaust flange kits or something and the piping also.

i found some info of welding cast iron and it pretty simple. heres some links: http://www.buzzle.com/articles/welding- ... steel.html http://www.ehow.com/how_5051927_arc-weld-cast-iron.html http://www.thefabricator.com/article/me ... -cast-iron

If you want totally new, awesome, badass flanges, get a gasket, give it to a friend that has some sort of CAD software, and get him to mimic it into a drawing (give it about 3/8" thickness or so), and send it to http://www.waterjetcutting.com. Have them water jet it out, or laser cut it... BAM, a whole new set of flanges in whatever material that you want (which should be Steel).
These guys could also be used for any custom brackets you might want. Turbos, superchargers, etc.

that would be an awesome have you ever bought from them?

[PapaSmurf2k3]

Just ordered some stuff from them for work. Some complex bracketry cost me $150 shipped, including material. It was 10 ga. steel, so a little thicker than 1/8". They can cut up to 6" thick stuff.

[venom90s]

oh ok. yea i did see that they can cut up to 6" thick.

for some reason my car couldn't start today, the only thing it did was turn the crank and shake the engine really bad. so after my friend and i brainstormed my friend disconnects the number two spark plug wire with no clue what would happen. so them he tells me to start it up again and it turned on with no problem. i then turn it off and reconnect the plug and i started up and it turned on with no problem. so my question is what do you think happen wrong? i know it has something having to do with the ignition

[breadbox]

So anyone wanna guess what the worst that could happen from not having a pivot ball retaining clip on a throw-out fork? Is it more of an extra measure or will my fork fly out of position on the first down shift?

You will blow through slave cylinders like nobody's business. It puts a tremendous amount of side loading on the internal pistons in the cylinder, tearing seals. Get used to shifting without using the clutch. Definitely want to replace that pivot bolt.

Sounds like sheer coincidence that it started with the wire disconnected. We'd probably need more info next time it does it. You'll have to pull a plug and wire and see if you're getting spark, etc.

[breadbox]

Good to know. I'll take off the trans again clean it up and install my new Rock auto switches.

[venom90s]

would there be any problems if i were to use the wiring of the stock electric fan to connect 2 12in fans?

[Mitchum]

I'm doing a 5 speed swap and the guide on the tech section for S14's says ill need a new 5 speed "finisher plate". After reading it sounds like Finisher plate=Center console(Ive never heard of "finisher plate"- is that used normally and I haven't heard it?) So will my automatic center console be the same?

It also lists a 5 speed cross member. Again im not 100% sure what that is-maybe I refer to it with a different name?

Thanks a lot

Not entirely sure, but why run 2 12in fans? I run the stock AC fan and have 0 overheating problems, and I'm in the dirty south.

I've never done the 5 speed swap, but maybe these writeups are better:

[Mitchum]

Thanks for the help-after reading through the second guide it appears that the "finisher plate" is the plastic rectangle type piece that the leather boot attaches to within the center console.

[venom90s]

i've been running with just the ac fan too but my car has been overheating so i was thinking maybe 2 12in fans would solve my problem.

[PapaSmurf2k3]

Is the car stock? How old is your coolant/thermostat? I'd probably start there before trying to tackle that project. I've seen lots of fan-jobs go bad, and people ending up with no fan at all.
Does it overheat while you're driving at highway speed?

[venom90s]

yea its pretty much stock it just has a aftermarket muffler. i already replaced the thermostat 2 weeks ago and it did lowered the temp compared to the other thermostat but i guess the problem is not there. it does heat up when going at highway speeds.

[PapaSmurf2k3]

If it overheats at highway speeds, then fans aren't going to help you. Look for any type of blockage, or upgrade your radiator.

[nismoracingsx]

might want to look into your water pump as well..if the fan clutch is shot and its not even spinning, then you have no flow

yea its pretty much stock it just has a aftermarket muffler. i already replaced the thermostat 2 weeks ago and it did lowered the temp compared to the other thermostat but i guess the problem is not there. it does heat up when going at highway speeds.

Try starting you car up cold and taking the radiator cap off. Then wait for the tstat to open and watch in the neck so see if the coolant is flowing.

Oh, and to comment on a discussion much farther up on thermostats...I live in the south east and run year round with no thermostat and have done so for years. Still get decent mileage in the mid/ high 20's and car runs fine to this day. GL

And on to my question!



The black box on the right that connects to the intake. Searched and found some references. Nothing concrete. Apparently its to heat the intake air or something during startup? I'd investigate myself but i'm deployed
Could I remove that without issues w/ driveability? I figured it was emissions related, but will not having this heater box thing hurt my mileage that bad?

Love this thread, it's my fav

[PapaSmurf2k3]

Yeah that's your "AIV- Air Intake Valve" or "PAIR" valve or something. It's function is to aid in heating the engine up faster when its cold... it really doesn't work too well, and later 240s didn't have them. Yes, you can remove it.

[nismoracingsx]

You're the man, papasmurf ^_^
Now, just have to remember this when I go home in 2 months = p

[PapaSmurf2k3]

IIRC, there were a few write-ups on NICO about it. You're going to have to plug the hole in your exhaust after you do it. IIRC (again), there is the "nickel trick" or quarter trick or something. You unscrew the tube from the exhaust, cut the tube off, and put 2 nickels underneath it then screw it back down. Its pretty straight-forward.

[nismoracingsx]

i'll try an search it out, thx

[Skyline_BNR34]

I had something similar on my Golf, except it was a heat shroud covering the manifold and ran a tube into the air intake box, I removed the tube on it but put it back on when I sold the golf.

[rootS13]

Im at the very end of my 5 speed conversion but I cannot get the transmission onto the shaft on the back of the engine. The pilot bearing was replaced and put in all the way and the teeth fit fine through the clutch and bearing. I think something is in the way but Im clueless. I have already removed the clutch/ flywheel 3 times to try different things. Any help/ advice is appreciated.


Edit: The car is a 90. The engine is from a 98 and the transmission is from a 91. From what Ive searched, I should not have any problem with this combination. It appears that the transmission gets caught on the nipple that holds the dust plate on and also that the bolt holes do not line up correctly. I called it quits recently since it was getting dark. Again, any input is appreciated.

[venom90s]

yea i believe the radiator i clogged cuz i can see that the coolant isn't flowing and i even put another new thermostat just incase. i noticed right after i installed the new thermostat that the coolant was flowing and the temp was in the middle but then it just started to heat up and the coolant wasn't flowing anymore.

[truckmtr240]

Is it even worth it for me to get a new intake for my stock 91 240?

[speedeast]

^ Sure, why not. I've never heard of a Stock setup choking, but an intake is key if you ever upgrade the exhaust. You might even get something noticeable out of it.

So I live in CA, and have a newer friend interested in parts off a 300zx 2+2 im parting out. Hes helped me a few times with my s14 for pretty much free and wants to know what he can get the 5 lug conversion, front brakes, vlsd and axles for. Im not sure on pricing for all that so there's my question? haha. I want to give him some sort of deal for helping me out but Im also looking for some coils for my car so...

PS thanks speedeast and papasmurf for being ballers when it comes to answering questions. everything Ive asked on here has gotten an answer from one of you two. <3

[heggytime]

ok my simple question is i have a 93 coup and i need to check the ecu so i got a obd2 and i cant find the plug under the dash to plug it into...do i need a obd1? also i did ready the sticky on testing ur ecu but my car wont turn over at all so from what i read thats out of the question...also this is what my cars problem is...i tried to crank it one day and nothing so i thought dead battery so i charged it for 10min then it crunk fine like normal....next day charged it again and it wouldnt turn over unless i pumped fuel while i crunk it...then after it was crunk had to keep pumping fuel or it would drop to 0 and die also horrible sputter and miss and wouldnt rev past 4000rpm...gave up for that day then next day it wouldnt do anything at all...checked maf that looks good i left car out with no hood in a rainstorm(very bad rain storm) so i unpluged connecters and dist and all that and cleaned pretty good...thx

In good condition, I would throw $400 at him. ($80 each axle, $100 for the VLSD, $100 for front brakes, $250 for conversion = $610 without a multi-item discount most people give)

Feel free to start a thread about this issue, as it might get complicated (too much so for this thread). There are a lot of problems that could be causing this, usually a combination of problems is likely and hard to diagnose. Testing the ECU on a 93 will not include an OBDII scanner as it is OBDI. You can check the ecu codes by pulling your ECU out where it is visible and determining the codes it's throwing per the following thread:

1991-1994-240sx-reading-computer-ecu-codes-t253912.html

Start here and then let us know what you're getting and we can make sense of it all for you. Some codes are thrown simply because other systems are faulty, so don't assume everything it says that's messed up is indeed messed up; check back with us first. Good luck!

My dad and I have sort of hit a brick wall.
We put all of the timing on and had every single mating mark matched up, everything was TDC, when we turn it we get no resistance so there is no valve to piston contact.

My question. Are the mating marks ever going to meet up after they are initially put on? We turned it multiple times they never did. So we pulled everything off and tried it again, and we still cannot get the marks to meet up again.

[speedeast]

^^^^^^^^^^^^^^^^^
The mating marks are for installation only. Once you start turning it, they don't matter anymore. You can still get it back to top dead center when the #1 piston is at the end of it's compression stroke. Once everything is together with the mating marks in place, you're golden. Don't worry about the mating mark meeting back where they're supposed to be. Good luck.
