1st gear not fast

[SilviaS14KA24DE]

New to the boards, and just purchased a 1995 s14 5 speed.

I've had it for only a few days now, and it's a beaut. I've noticed that accelerating hard in first to second (stupid tailgating civic dx with a beecan sound muffler), it is slow. In otherwords, acceleration is not as fast. I saw an altima right next to me pull almost the same speed until I got to my high end, then which i pulled away fast.

I don't know if I sound confusing. I guess I'm basically saying that my mid-range isn't pulling very fast. Anyone with knowledge to this? Maybe need CAI? (as i was reading in the FAQ) A new fuel filter? HELP!

[Silvia007]

Fuel Filter, pick up one that's for a 300zx.

I've said this before, but In my S14 my 1st gear is also crap. My second and third are decent, and my forth is very strong. So, I'm in the same boat as you. And don't underestimate a honda, they are geared really well 1-3. But after that, most honda's REALLY start to tamper off. My friends bone stock 95 civic ex can hit 65 in second, when my 240 hits like bearly 55.

hmm....in my s13 i rarely get beat off the "line" in city driving on 1st. I know it's really short, but weak? I don't know i'd say start checking stuff up, Like i'm saying, it's really torquy in 1st (even kind of bothersome), but I don't know if it has anything to do w/the pwr/weight ratio of the s14.

[methodchris]

i drive a 97 s14 and 1st gear pulls real hard...barely get to use first it goes by so fast

[TachyonS14]

Well, I think we can all agree that first gear is way too short. I really have to keep my eye on the tach because It gets up fast.

[SilviaS14KA24DE]

Fuel filter eh? I was looking at the FAQ about that. Some guy asked about it because lack of High end power.

So Sil007, what brand do you recommend for the fuel filter? and is it compatible?

Ok, i'm nub at installation, but can anyone tell me how to install the fuel filter in a non-nub way? hehe thanks

[240Knightrider]

hey check your compression, I got the same problem with first it goes away if I do it just right. If I pull up to a ricer I just have to get a good start off. If I dont im done for. But I agree first gear is way to short, second is pretty good though, I can keep in till 55.

[Chingon]

1st is good 'till 15~20 depending on car....but it's short....I use Fram filter (it's cheap) there are better like k$N and mobil 1. Fram has the grip end though. Installation is straight forward, although oil change is recommended w/every filter change.

1. locate filter2. unscrew filter counter clock-wise3. oil new filter and fill it up....(mind correcting me if wrong?)4. screw new filter back in, hand tight only.

[methodchris]

hm he said fuel filter not oil filter

[whiterps13]

is your clutch slipping? that could cause a big lack of acceleration due to the torque a ka puts out.

[Chingon]

haha...missed it. Well that's not as messy. Bosch and k&n make good filter for that.

1. locate fuse box, and fuel pump fuse, take the fuse out.2. start car, it'll die out due to lack of fuel.2.5 maybe a good idea to unplug neg. terminal of battery.3. disconnect both fuel lines from filter Really Yank those suckers out.4. install new filter ( i recommend a z32(300zx 90+).5. Force the big filter (if z32) into the clamp that holds filter. It'll fit.6. put your fuse back in there.7. turn ignition on so that pump fills line w/fuel. After a couple of secs, crank engine 'til it goes on.

FYI: fuel filter is by the battery, mounted on the passenger's tire firewall.

[Silvia007]

Purolator, if that's how you spell it, at your local pep boys probably the best place to get it... yep, just walk right past the neon lights and the APC window stickers... funny I actually see people around my area with APC windsheild stickers... YUCK!

[SilviaS14KA24DE]

Thanks! I forgot what brand the 300zx filter i got (a 96 from autozone).

The big filter works like a dream. I noticed a big difference in mid range of acceleration and top end in all gears.

I didn't have to remove any of the fuses, it just worked fine.

Note for reference:1. Open gas door and take out fuel cap

2. place a towel that you can throw away right beneath the old fuel filter.

3. Clamp top hose with one of those pliers that clap and stay that way and move the C clamps a little up the hose. Have another towel ready to catch some gas that will leak out of the hose. The hose is rather hard at first to take out, but just twist it until it does.

4. Do the same exact thing as 3, but on the bottom hose.

5. Connect new filter to bottom and top hose, clamp them, then put the filter into the metal holder.

6. Clean up and DONE.

Make sure you put another towel underneath to catch dripping gas. I dumped my old fuel filter to an autoshop near by. THey should easily take it away.

Thanks for all your help guys!

Easiest upgrade i've ever seen

[extheflow]

yeah,the fuse pulling thing was just included to keep from needing the towels. if you pull it and let the car die on it's own then there's no pressure in the lines.you barely get a dribble when disconnecting the lines.

w3rd.

[Dattebayo]

besides, pulling the gas cap really isnt gonna work, is it? I thought 90+ cars had tank stoppers to prevent leaking gas when they flip over.

[SilviaS14KA24DE]

removing the gas cap only will depressurize it so not a lot of gas will come out when you pull the hoses. When you get gas and take off the cap, you should hear it depressurize

[Peabody]

Sould you get the same 300 filter for the year of your car? Are the years any different? If I have a 90 240 then I should get a 90 300 filter? Does this make any sense?

[SilviaS14KA24DE]

just use the latest one possible. Which i think is a 96

[kyle1911]

my my S13 with the KA24E is there anything different imvolved in this?

which 300zx fuel filter should i ask for? N/A or TT if there even is a difference.

[SilviaS14KA24DE]

my friend just installed his 300zx filter into his s13 SE. You'll notice a difference in the pick-up.

As for which filter, all i did was ask for a 300zx filter and the latest model. I don't know if there is N/A or a TT model filters, but if your car is N/A, then get teh N/A one. Vice versa for the TT.

[Chingon]

na and tt are the same.

[SilviaS14KA24DE]

yay! random post.

[Bbill528]

hate to say it, but a stock ka24de isn't fast....should've gotten a z28 if that's what you were looking for....

[C-Kwik]

1st gear will accelerate fastest for any car provided the motor doesn't change output at all based on gearing(some turbo cars will do this to some extent).

If you make the gear taller, it will accelerate slower in first gear.

I fuel filter will not add power unless the existing filter is clogged. As long as fuel pressure is good, then the FPR will regulate it and allow the injectors to spit out the proper amount of fuel.

A clutch will slip more in a higher gear as there is more resistance.

SILVIAS14KA24DE: Are you referring to your midrange RPM not being strong or your midrange speed? If there is indeed a problem, adding mods aren;t going to help. You want to make sure the motor is running strong on it's own.

Keep in mind the 240sx is not a rocket of a car from the factory. The S14's generally pull about a 16 second 1/4 mile in 5-speed trim from the factory.

[NeverEnuff]

1st is good 'till 15~20 depending on car..

well if your shifting out of ferst at 15-20 mph thats your prob lol i have 92 and it will do around 35-40 ferst gear and all 240s use same trany rite

[Chingon]

shift at 35-40 in 1st?.....well, you could do that, but why?

[Bbill528]

could you though? i know for a fact i can't go 40 in first gear.

[Chingon]

could you though? i know for a fact i can't go 40 in first gear.

I'm guessing if your engine is top notch and after a minute of redlining it....
