High 14sec NA KA

[Shift_Dr1ft]

I would like to build a high 14sec NA ka24de and still be able to pass smog. I was wondering if these parts would get me there: injen intake, 2.5 cat-back exhaust, headers, crank pulley, flywheel, 3" cat, and brian crower cams. I have read through NA builds but they mostly dont pass smog. I have read through Bigvinnie's thread but he doesnt have 1/4 mile time.

you can always add a 100 shot

headwork is key. bigger valves, stronger springs, porting and polishing, also big ass cams.... also super high compression pistons for the bottom end and a better flowing intake manifold... that'll be a basic na build. use factory exhaust parts mostly... get a 3" remote cutout at the dp. and open it up at the track only. hehe.

that also keeps the sleeper exhaust look so cops wontgive u a ticket for modified exhaust well if u live in cali,also
gut as much as you can,

nah I am cool with nos, this is a DD car it need to be reliable. Doing the internals seems to be my best bet but i want to see if i can reach high 14 sec with all the bolt ons with safc2. My main point is to pass smog, cali. I am just looking to be quick not fast.

Focus less on power and more on everything else.
Drive train, tires, suspension, weight reduction, ect.

and practice on driving skills. a fast car is nothing if you cant handle it.

[woohaa]

i have welded diff., toyo proxies, coilovers, cf hood, and stripped back. I am not looking for 1/4 quarter drag if some of u might be thinking. thanks.

[woohaa]

but i do decent times for stock KA, try those mods. if u have not got them yet.

[whiterps13]

woohaa, that post is worthless. Coilovers and a carbon fiber hood are going to do next to nothing to improve quarter mile times. The OP didnt ask for your mod list (however pathetic it might be).


On a more serious note, definately get some drag radials or full slicks. Even on a low-powered car (and every NA KA is considered low power), getting a consistant and solid launch can drastically help your times. Other than that, search for all NA KA build threads, this topic has been discussed so many times.

[Shift_Dr1ft]

well i am not looking to drag race my car, so i wont be getting slicks. Like i said i just want a quick dd car(i consider a high 14 sec car for dd is quick enough for me). I have searched through the NA builds but most dont have 1/4 times so i dont know if i should follow the build also being able to pass smog which most of their builds dont pass smog.

[Shift_Dr1ft]

maybe i guess i am just asking for too much? i guess you can have both being quick and passing smog. haha

I'm not a drag racer and never will be, but back in the day we'd go run the track once in a while out of sheer boredom. My car at the time weighed 2520lbs, S14 SE with sunroof, heavily lightened. Mods were:

Short intake, relocated to battery location
Hotshot header
S13 cams
UR pulley
Aluminum flywheel
Aluminum driveshaft
HKS Twin Power ignition
JWT ECU
Greddy PE exhaust

Dyno'ed at 159rwhp.

Car ran it's best time of 15.1@96, traction limited because the suspension was stiff as a rail. I think it's possible to break into the high 14s with a good set of tires, soft rear springs, and a little more power, but by that point you've spent a shit load of money already. All my emissions equipment was tossed, so factor that in too. Again I'm not a drag racer, I hit the rev limiter a lot, didn't catch the light just right. That was also like 8 years ago.

[Addicted2Kouki]

Talk to BigVinnie. As in PM him. He's ALL about his street legal NA build. Dont just skim thru a thread.

[Shift_Dr1ft]

thanks projectrdm, i will look into that setup.
addicted2kouki, i think i will do that.

[NiGHTS]

gearing is the biggest thing for good 1/4 mile times.

I made 162WHP with half that Bull shit listed, and stock timing. JWT ecu's suck unless you specifically tell them how you want it tuned. Other than that they will only tune to a safe minumum by barely changing the fuel MAP, and barely changing ignition as well. I pretty much proved that by using an SAFC.N60 MAF makes a huge difference as it changes your RPM choke point from 5800RPM to 6500RPM.

I even started a thread if anyone has questions.

I didn't know this was a pissing match, and I sure wasn't trying to impress anyone, I was just adding to the thread since the OP was looking for ideas. That car is long gone and most of that 'bullshit' was done back in 1998. If you're going to take it so offensively, maybe you should take some pills or something.

Definitely not a pissing match but to say the best one you have seen or driven with light mods was only 159WHP is somewhat an understatement. Theres guy's out here in Cali Pushing over that 159WHP mark and I happen to be one of them. I shouldn't brag either because 3 WHP isn't a huge deal.
The one thing that I have hated about the forums in general are people that can some what underdog an engine to make it look like a piece of crap. Really the KA can easily make 170WHP with bolt ons and the right tuning. My engine is missing out on 8 more WHP just from the crappy paper filter, timing settings, and the fact that I use a 2.5" exhaust rather than a 3". Not to mention I can probably enhance the engine for another 7WHP by cracking open the oil pan and grinding the girdle off to just leave it for mains with out unbolting the crank shaft at all. there are so many free mods and not removing the smog emissions shows that there is great potential for this engine.

Sorry wasn't attacking you I'll take some muscle relaxers and a celexa or something.

which header has the best durability, power, and fit for the KA? i was looking at the dc sports as i haven't seen the hot shots for sale anywhere lately.

Mine is a DC sports, it's dyno proven and if you need the exemption for smog, all you have to do is FAX or mail a copy of your receipt toAEM/DC sports to get the exemption sticker.

[JoeC1982]

smog? we don't even have inspection, lol. thanks for the info though.

[norcal_black240]

Its highly possible to get into high 14's on a dohc S13. Friend has a S13 with header, test pipe, exhaust, aem intake, advanced timing, diff from a R32 and he ran a 15.1 at the track and he had the back seats and spare tire taken out of the back.

Ive also seen stock dohc S13's run mid 15's.

I think with the mods listed below if your a decent driver you should be able to consistantly hit the high 14's in a n/a KA without doing high comp pistons, port and polishing, etc.

good tires with right pressure in tire
minor weight reduction
aem intake
hotshot header
test pipe
exhaust
vlsd of some sort
good clutch and lightweight flywheel
1 piece driveshaft
advanced timing
Jwt camshafts
Jwt cam gears

You say you're not attacking me, but you just did it again. Where did I say "the best one I have seen or driven with light mods was only 159WHP"? And how did I underdog my engine, to make it look like a "a piece of crap"? It was my car, my personal experience. I never said it was the fastest, most powerful, or best built KA. I simply added to the thread. I don't think muscle relaxers can help you at this point.

wanna trade for my 3" exhaust for your 2.5" exhaust?

[dragon_x330]

Buy Brian Crowers new fully counterweighted crank , build the head, higher compression pistons, forge the block, ITB's (so you can take advantage of the new higher revving engine thanks to the counterweighted crank) etc etc etc. I remember seeing somebody here on Zilvia with a KA24DE with JWT Cams and ITB's and he hit around 180 hp if I remember correctly.

[JoeC1982]

forge the block? good luck with that one.

[jussjepbrox]

this is true my homie put 100 shot on a KA.E, 3inch exhaust, msd and welded diff and raped the shit outta mustangs n camaros not sure if he took it to the track

[Ineedparts]

I ran a 15.4 with just intake and exhaust. Its a 91. You should be able to hit high 14's with some head work and cams easy....

ITB's are horrible to tune for an all weather environment.

Also what the hell do you mean by forge the block?
How do you forge cast iron which in fact only becomes stronger to high heat temperature?

Square decking would of sounded a lot better and can yield 3~5whp, it balances out each cylinder.
