Majorly disappointed with the 240sx

[4banger]

In the faq's it says how to disable the speed govener from the computer they said to splice a toggle switch into the 8th wire down on the left (the yellow w/green stripe). I did this and it kind of worked the car dosen't stall at 111mph but studders at 115 mph. Do I have to disconnect the Rpm sensor also, to get it to work totally. Or will even work? If I can't take the governer off this car is history. Liked the 240 but having 100 horsepower hondas blowing by you on the freeway sucks. I have a 94 Z28 so I thought i would get an import, major disappointment no torque plus the thing is limited on the top end what use is the dual overhead cam if it has goveners on the speed and rev limiter. Please help me I like the car, but the way it is looking I'll probably sell this thing to some kid who wants to put a big muffler on it and make it sound fast :pface

[singlecamhonduhkilla]

YEA THAT IS DISSAPPOINTING TO KIK ALL THESE KIDZ AZZEZ ALL THE TIME AND THEN JUMP ON THE FREEWAY AND GET SMOKED.. HAHA SAD BUT A POS CIVIC GOVERNS LIKE AT 120 OR SOMETHING.. I WOULD BE HAPPY TO GOVERN AT 120.LOLJOE

[MaineExport]

Hmm... looks like you have your expectations set too high. It's a heavy car with only 155 hp.... what do you expect?

Anyway... I'm not sure what year you have, but because your governor is set so low it must be an s13. The s14 speed gov. doesn't kick in until 120 MPH. But anyway...you still have to disconnect the 5th gear sensor. That will eliminte the RPM gov. Sorry you're so dssapointed... you should probably sell it anyway.

[Structure240sx]

is it different for manual and auto 240's? i had my 95 auto a lil past 120 well thats what the needle said. im doin the 5spd swap along with turbo this month hopefully it wont cut at 120

[cow]

Man that's weak.. I've gotten my Integra up to 130 and I know it can do more. lol.

That kinda sucks huh.

[trpower7]

I think you assesment was ignorant from the beginning, especially if you think you're going to compare your Z28 to an import. Why do I have a feeling you were swayed by F&F language and thought that an import would be amazing. The speed limiter is there for a reason, insofar that you shouldn't be driving 110 on the interstate. If you really want to get rid of it get a JWT ECU retune, no speed limiter no rev limiter. If you even faintly expected it to have anything even close to the torque of your Z28 you're sorely mistaken. Go drive a Honda and you'll find out that for a 4-cylinder import the 240 has gobs of torque. It trades it's torque for lack of "high-end" i.e. our motors run out of breath at around 5.5K RPM. There are ways to improve this, as there are ways to improve the faults in any car. What a stock 240 lacks in straight line speed it more than makes up for in the twisties. That's the strong point of the car. Go do some research, your opinion is narrow, biased, and ill-researched.

Actually, the top speed limiter is frequently set to coincide with the maximum speed rating of the OEM tires

[mickee]

do you trust ur car to go that fast??? i mean its old dude.... wear and tear is crazy on those boats.... be careful what you wish for.....

[jrc90240sx]

Just get a JWT return. works great, and will get you a little power, and broder powerband. i am pretty sure i could hit 140+ in my car, just no way of telling unless i do some math, or followed by a car that is able to go that fast with a speedo to show it.

Yeah... but by the time you get that pig up to 130... I'll already be at the rest stop a mile ahead, sipping a coke.

[trpower7]

Yeah, the speed limiter is about safety, and the strength of your suspension and tires. At speeds of over 100mph alot of components are getting stressed more than they should and alot of small bumps in a road become cannons to your tires and suspension. Also your tires will be pushing the speeds and temperatures at which point the compound remains solid instead of liquid.

[drifter]

Why do you guys need to be going this fast? Sounds unsafe.

[jrc90240sx]

well i normaly dont go over 90-95, but on long trips i will take it higher now and then. there really is no reson to go over 115 though, unless your car hits it in the 1/4 and its keeping you from getting your sub 11sec time.

[trpower7]

even 90-95 on your average interstate is unsafe. Expect to run through tires and suspension components REALLY quick at that speed, and if I had the mathematical calculation sheet I'd show you the more frictional stress you put on an engine in 10mph incremements over 70, made me think twice about busting 85mph home every trip. I do agree about the quarter mile thing though, it's why JWT is there.

[groundhogday1976]

I've heard several different speeds for the limiter. I've taken my '93 fastback to 115 and never hit the speed limiter. My balls aren't big enough to try to find out how fast it'll go, plus the speedometer only reads to 115 anyway. Actually 115 is way faster than I wanna go, I just wanted to "see what she'll do". I agree that public roads are no place for triple digit speeds and I shouldn't be going that fast anyway.

[EZcheese15]

Auto's are not speed limitted, only the 5spds. And they are *all* limitted to 112mph. What your speedo actually says when it kicks in may be something different, but that is just speedo error. The actual limiter is at 112 *REAL* mph.

[Meantime]

I own both 240 and Z28...and have learned to love my children equally. They are both special in their own ways.

I agree triple digit speeds are very unsafe. American roads are great compared to other countries, but they still aren't glass-smooth and specially compounded like the Autobahn. Something that goes wrong at 50 mph and leaves you stranded could probably kill you and 10 other people at 100 mph. Not to sound like a nagging mother, but really, be careful.

[4cefed]

I hate to keep re-hashing this subject, but I unplugged my 5th gear sensor and I still have the fuel cut at 112. I have a 92 240. I have the shop service manual, so I'm pretty sure I got the right plug. Is there a back-up to the 5th gear sensor on the 92's?

I don't have a real NEED to go much faster than that, I just don't like being TOLD I can't go faster.

[trpower7]

To defeat the speed limiter, wire cut at the ECU and unplug the 5th gear sensor. Gotta do both. Search for "speed cut removal"

[Megaseth]

when you remove the 5th gear sensor, will it still register on the Tach? i.e. still show the rpms

andi really dont like the way the limiter cuts the fuel. thats really bad on the engine. if it wasnt so damn expenssive, i would get one of those rev/speed limiters from autoimaging.com that cuts the spark. its a little safer, but gives you a F&F flame out the a$$.

[MaineExport]

Auto's are not speed limitted, only the 5spds. And they are *all* limitted to 112mph. What your speedo actually says when it kicks in may be something different, but that is just speedo error. The actual limiter is at 112 *REAL* mph.

So.... is there two speedo sensors... one for the erroneous speedometer and one for the *REAL* reading on the ECU? Or, is it just that the speedo gauge is analog and wrong as a result... and the ECU reads a digital signal?.... I'm confused.

[c32c7]

public roads are unsafe at those speeds but for those of us who are on the track, it sucks to have the govener kick in on the front straight.

:Werd My feeling is that top speed isn't nearly as important as acceleration. I heard once that if speed were exciting, you'd never go to sleep on an airplane. Acceleration and how fast you can do it is where you have your fun!

[xxtrizz]

Hmm I wonder if top speed isnt very important, then how cme more people dont get the KA engine and turbo it? Just rebuild the KA and put a turbo on it. More torque for dat *** please?

[Nathan]

Uh....we do. http://www.nissaninfiniticlub....d=131:D

[creophus]

Torque and acceleration go hand in hand. I decided to go SR because I don't have the know-how to prep a KA for turbo and money to pay someone else to do. Therefore I followed the masses and got an SR. Taking off and watching your passenger's neck snap back is where its at.

[DGA]

Get an SR swap, or go with a VW 1.8L turbo GTI. That is what I had before my two 240s. With a a little chip you will get 200+ hp, and 240+ ft-lbs of torque. I hit about 147 MPH with this set up and a set of proper rubber to handle the speed.

In my opinion, get an SR swap. You have a proper rear drive car, so stick with it. VW have a lot of problems, and Hondas are great cars, but they are like butt holes, everyone has one. I had two. 240 is more of a unique car that has a trumendous aftermarket support, and it can easily be a reliable everyday transportation making 350rwhp with an SR engine.

[LiU]

I think the original poster is missing the point:if you're expecting a stock 240sx to dominate on the freeway you'll be sorely disappointed. However if you love the curves and twisties... well you wouldn't be posting here. Even if you disconnect the sensors or get your JWT ECU, it still would not make the 240 a highway beast by any means.

It's all about what you want, and if attacking curves is not your thing, it's best to sell it ;]

[SHIEF]

PUT AN AUTO ECU IN THE CAR, OF THE SAME ENGINE!!!!I.E. sohc-S13, dohc-S13It gets rid of speed limiter, and rev-limiter yet everything works just like it did before. Unless you have and auto to begin with, then that just sucks

[shinrekka]

dude if you want to go fast in a cheap *** car get a 1989 taurus SHO, i buried the needle at 140mph and it was still pulling. But i dont recommened doing that for to long, (3 mins) i blew the engine so bad my hood opened up and i almost died
