[sleepingpanda93]

ok got an 89 240sx when im driving on the freeway when im in 4th gear or 5th gear i lose power as soon as i hit 3500 rpm and by lose power its like i popped it into neutral and my rpm's begine to go down, the car doesnt turn off or anything but it does stop letting my go any higher, already checked my maf and for awile it did like me go to about 4500 or so but i didnt need to keep going and next day lost power again at 3500 so idk wat to do now.. help?

[PapaSmurf2k3]

Does it hit real hard, like rev right up to 3500 and then start slowing down immediately (like you're completely off the gas, in gear), or does it struggle to get up to 3500 a bit, and then slowly start to come down?

This should point you in the direction of being something electrical (like a speed limiter/rev limiter that isn't working/intermittent MAF connection), or mechanical (fuel pump going out, fuel filter clogged, runs lean and bogs you down).

ARGHHHHH I just don't get it.
My SR20DET tuned with an APEXI PowerFC idles like poo. I have replaced the IACV, set the TPS, ensured there are NO leaks anywhere. I am also using a MAP sensor with this particular PFC.
The car, on startup, will idle high, and then choke itself out after a minute or so. I have to gas it to keep it from dying. After warmup, it still does the same thing. And when I am coming to a stop, I need to heel toe just to prevent the motor from stalling as I slow down. It's really irritating having the car shut off at every stop. Another thing, if I manually stabilize the idle (I can give just a little bit of throttle right as it chokes out) and it will idle fine. Then, after it idles for a minute or so flawlessly, I give it a little rev, and when it comes down, it begins hunting again and sometimes stall. I'm at a loss, I have no idea what's going on here. The wideband shows the mixture leaning out when it chokes.

I've never messed with a PowerFC. Can you datalog with it? Maybe view your IACV duty cycle, O2 sensor input, injector pulse/duty cycle, coolant temp sensor, etc?

Hey, new here.

Bought a project 240sx - very first car.. kind of a dumb question, but can anyone please tell me how to remove the spare wheel in the hatch? I can't seem to figure it out, and there doesnt seem to be any bolts except a bolt that looks like a T holding down the tire, I just stripped the interior and cut out some major rust patches, and there seems to be some water in the spare tire well, just needa clean it out - thanks!

I don't run a spare tire, but there should be a clamp in the center that keeps it bolted down. Check your jack area for a tool to remove it. It should also be in your owner's manual.

[mechanicalmoron]

I could be wrong, but I don't think it takes a special tool, mine never had one (but I never got the jack either)

It's the T-shaped bolt in the middle of the spare. That's just a handle, it's like a big wing-nut. Just turn it counterclockwise, if it doesn't unscrew it's jammed and just needs some oil and tough love.

Hi guys. Simple as it can be
What this wire is for? They all come from electric box in front of air box.


It has a blue/green insulation.

[PapaSmurf2k3]

Weird. What engine is in there?

What is this? It appears like something on the frame is mangled and broken to me. I'm looking at buying my first 240sx (This one is a hatch) What is the deal here?

I posted the question to some of our CA18 moderators. Hopefully one will chime in here.

Looks like someone effed up their frame rail either hitting something or trying to jack it up by that point. It should still run and drive fine, but you might want to try knocking a few hundred bucks off their asking price because of it.

Don't know if ur still having problems with ur 240 when ur hittin 3500 in a high gear,but I've had 240's for awhile now and my second one did the same thing and it was VERY intermittent. As in it did it totally randomly some times and then all the time when it was at O.T. (operating temp/ warm engine) What it ended up being was the distributer wiring on the distributer. Try having a shop O.B.D. it (on board diagnostic) If u have OBD1,which it probably dose(unless u have a dif engine than the stock KA24) ,they will have to drive it until it dose what ur saying it dose and drive it back to the shop,keep it running, and plug into the ECU and read the codes that are firing off when ur car loses power when driving.OBD1 dos'nt have a memory to store the info about sensors reading problems in ur engine.So when ur driving and it happens and u go home and turn ur car off the ECU losses all the info about what was going wrong with ur engine.Where as in OBD2 CAN store any info about sensors reading problems internaly in ur engine.Long story short....Take it to a shop u trust and then tell them to drive it till it losses power like u said and then have them bring it back and check the ECU while it's still running after the test drive.That should give u a broad spectrum of what could be happening.Best of luck!

Is it anything major that would require fixing or effect the car in the long term?

[PapaSmurf2k3]

Not really, no... unless the undercoating was removed, then it might rust.

Wanted $5999 said 5300. I think 5k is reasonable. Clean title , nice body.

All its missing is 1 ac line and recharge

As long as you do it properly, it can be eliminated without issue.

What year is it? 5 grand is a pretty good price I'd say.

[PapaSmurf2k3]

Sounds like you're asking if the transmissions are interchangeable. Yes, they are.

Whats up new to the forum figured id introduce my self some
names andy i drive a 1996 240sx se
live in the north ga area
newb question looking into swappin my car to a 302, wiring and such is no big deal to me but wondering if there is write up any where to get some more info. Ive seen plenty of s13s swapped to a 5.0 but not many s14s so im lookin for as much info as possible, thanks in advanced.

[PapaSmurf2k3]

Everything should be relatively similar between S13 and S14, except the wiring, which you said isn't a problem. A 302 --> S13 write-up should be a pretty solid start.

[slideways96]

ive been told i can use 460 big block ford mounts in my s chassis and they bolt right up to the block and chassis. but ive also been seein in s13s they have a stabilizer bar on the driver side. reckon that's absolutely needed? and what about the oil pan clearance?

[PapaSmurf2k3]

Swapping a 302 into an S14 chassis is a little outside the scope of this thread, especially when you're talking about the specifics. You'd be better off starting your own thread.

[Chief1402]

I have a 96 240sx I was in a wreck last weekend.. Police report has my car down as a "3" for severity..can you guys tell me what I'd be looking at to fix it? Or if its better to save the cash for another car. I can't post pics off my phone and I know that doesn't help... Damage is to door and quarter panel area, passenger side, door is pretty dented in, so is quarter panel, area of door frame close to qp is bent a little, door opens and closes with a hard slam. Damage goes from middle of pass. Door to the top of rear tire.

[PapaSmurf2k3]

It'd be pretty tough to come up with an estimate without actually looking at the car.

[Chief1402]

I have pictures on my phone I can email you or text them to you.

[PapaSmurf2k3]

you're better off getting it quoted by a local shop. Does it still run and drive?

[Chief1402]

Yes, runs and drives as normal.. my dad looked it over and the frames not bent, and now the pass. Rear window is about to fall out.. a friend has quite a few 240's and he's offering a entire passenger side for body parts. Plus he can weld a new quarter on for us. I'm just at the point where if its a cheap fix ill go ahead and do it, if not I'm gonna save for a 350z..
