pick up a few more tenths in the ka
 
i took my bone stock s14 to the track last night and ran [email protected] i just spent over my budget geting my car road wothy and painted and i plan on going turbo but i want to do it right so thats going be a while so whats a few cheap mods i could do to lower my times aliitle bit. Now i lied in the begining i have a 248in/232ex cam setup which totally changed my powerband (for the better) and ahollow cat, and hpracing muffler thats it i was wondering roughlyhow much cai and 4-1 header would help and i know i should just save up for the turbo but id just like to play around at the track alittle all suggestions welcome.:newbie:

mrmephistopheles 05-20-2006 08:33 PM

if you're looking to have a fast drag racer, sell your 240 and get a 5.0 mustang.
They're WAY cheaper to make fast.
For what it'll cost to get your car to the 12s, you could have a Mustang into the 10s.

edit: $5k and you're set.

DJPimpFlex 05-20-2006 08:42 PM

yea S13's and z32s are terrible drag cars. The rear subframes tend to jump arround WAY to much and give you massive wheel hop.

Irukandji 05-20-2006 09:01 PM

The secret is to have nawz and diamond plate floor mats.


Shhh! don't tell anyone ;)

I need 2 bottles. By tonight!

Get a Biki Rom, tune your ecu yourself. It's under $300. That will get you a few more tenths in the 1/4mile, you will need it anyway when you turbo to change fuel and ignition maps......

gearhead290 05-22-2006 01:05 AM

buy an ebay intake, put an K&N filter on it (~$60), then get a 3" exhaust.

m0rex 05-22-2006 01:15 AM

Booost it. Theres cars out there you can make fast in a straight line for cheap. But 240sx are fun when you make them handle good and go fast.

I've been looking more and more into ecu tuning too. I think ecu tuning is where it's at as well....

Realchaos1 05-22-2006 10:52 AM

Get 370cc injectors, then get an SAFCII ;] Advance the timing a lil

tre 05-22-2006 11:27 AM

15.6 on a stock setup would be considered impressive.

Considering a stock s13 can't break into the 15's ( to my knowledge )

My friend hit a 15.6 with his Intake/cat back s13

I personally hit a 14.9 I'm betting I can drop it down to 14.7 or 14.6 with a few more tweaks.

tre 05-22-2006 11:30 AM

14.963 @ 93.12*

Better shift points/launch alone would probably drop me to a 14.7. I hate 240k vlsds. Almost no better than an open diff lol.

junks13 05-22-2006 02:07 PM

first of all buying a mustang is out of the question i hate mustangs . tre what do you have done to yours t0 hit 14s

tre 05-22-2006 03:20 PM

Um. well here's my list of mods. Tune it to yourself (i'll display my tune, doesn't mean it'll work with yours)

AEM Intake (for now)
Greddy 4 to 1 header 2.5" all the way back, gutted cat
Fully Advanced Ignition Timing
JWT Cam Sprockets.
5degree retard Intake
7.5 degree retard Exhaust.
SAFC-II -11% Fuel Curve(after 4000rpm)

Things I plan on doing:
RAM air induction with z32 MAF
Locked Differential
LightWeight Flywheel
Better Clutch
Exhuast Cam on Intake side.
Maybe retard the cams a bit more. (IF i can accomplish the revs to 8k)

Remember this is my Drift Bitch. I do drags for shits n giggles lol

Tre you are going to need to explain to me how you came up with -11% After 4000rpm, or why you would even want to run it that negative in that high of an RPM.......Also why would you advance timing without an ecu tune?
Just as a reminder when you use the SAFC to set a signal from MAF to ecu that the distributor should be set at all times at 20BTDC, your running NA, not FI.
Advancing the distributor more than 8 degress sets detonation and it isn't even recomended to advance the KA's timing past 3degress of 20 BTDC for a total of 23BTDC. Advancing the timing doesn't do anything accept increase HC levels, actually decreasing power, running the KA at -11% on the SAFC has decreased your fuel dumping and shortened the pulse width, why would you do that, the KA already runs stoich a little before 5600RPM? I can understand running a -2% at early RPM's like between 1500~3500RPM.
The way you have expressed it to me your na engine should of blown up from detonation, I am calling BULL SHIT......

Again I am calling BULL SHIT when I see it. First off retarding the exaust cam 7.5 degress is retarded, for reasons I won't express to you because obviously you know nothing about math or even come close to understanding engineering...Secondly JWT adjustable sprockets only retard/advance 3 degress either way, and there is a good reason for it. So you defenitely didn't retard the intake 5 degress either.
You also didn't do an ecu tune which in no way the SAFC can account for, the actual MAPS of your ECU need to be reconfigured.
So with all this B.S non relative fiction I would say you run a 16.00flat in the 1/4mile, NO BULL shit.
Here's the link to the JWT web site!!!!!!!

You have no clue what posi traction or limited slip do. Just to answer it for you it should increase 1/4mile time since grip is applied to both wheels instead of one...
This is one of the reasons why oldschool Datsun720 truck owners weld there open diffs for track use. I happen to be one of them...
I also wouldn't be surprised if you just took that 1/4 mile time from a stock sr20det since that is exactly what it is...LOL

Uhh last year I hit a 15.3. This year an added ecu tune should set me at a 15flat or BETTER...........I have an s13, if you couldn't figure, and s13's have a lighter chassis nut case.....

junks13 05-22-2006 05:55 PM

listen i dont know much about tuning im more mechanicly inclined i know what it take to make an engine run better but when it comes to computers im bum fuzzled. How much would a cai and cheap header pic me up roughly and for the guy that suggested i get a mustang id rather run a 15.00 in my s14 than a 13.00 in a mustang because any moron with a little money can make a v8 run but i like a challenge

Get a OBX header if your cheap, or a DC sports if you want top notch power and quality.
TB coolant bypass is a free mod, but that is like a fraction of a donkey, it just keeps air cooler. If you have a federal issued ecu, you can do the EGR block off, it wont throw any codes on the FED ecu's and it makes the engine alot more jumpy since your engine wont consume hot exhaust gasses to replace air.
High flow cats are a must have and do the job.
You will need an ecu tune to get a flat 15 or better in the 1/4mile with those modifications...
P.S don't take advice from TRE he really knows nothing...

tre 05-22-2006 06:15 PM

Bigvinnie is obvious you've never tweaked an n/a ka with those statements made.

Its picture time now. And trust met heres quite a few people from WA on here who can vouch for me.

Brb taking pictures :) mucho <3

BigVinnie 05-22-2006 06:18 PM

HAHAHA bring on the picture show LIAR!!!!!! Bring on the PHOTO SHOP!!!!LOL
I've tuned KA's before you were born man, your full of dog poo......

ryan hagen 05-22-2006 06:27 PM

"RAM air induction with z32 MAF"

your car will run like shit, nissan mafs have a really hard time metering air that is rammed into them. sport compact car project 300zx is writen proof. on my ka when i did a cai in my fender well air from through the "brake duct" was directly ramming into the filter and my maf couldnt read it, it spit and sputtered and ran like ass abouve 25mph, i put a blocker in front of it then it ran great.

You got pwned buddy.

You would have posted pics with this post if you had them.

DJPimpFlex 05-22-2006 06:53 PM

^BIG VINNIE FTW!!! That tear down of his life was awsome!

tre 05-22-2006 07:41 PM

Upload pictures ^_^ hold on.

Oh btw i wonder why a company in florida puts z32 mafs on their sr's with no problem with an SAFC-II... hmm must be the "correction factor" they have

tre 05-22-2006 07:42 PM

oh yeah i dont even have photoshop so don't even cross that line

Those are a few pics of what i have.

For you not to hit a 14.9 and be tuning for so long is either:
A: you suck a tuning
B: you suck at driving

please choose one or the other, or maybe both?

Z32's are put onto sr's because they can be used for a wider pulse width 370cc injection and above......
The stock KA MAF accepts upto 250HP on 330~370cc injection. Using a z32 MAF on an NA KA is not needed.......

tre 05-22-2006 08:20 PM

choke point on my induction = MAF

If i can make it work. i'm going to do it.

If not i'll save up for ITB's
