Holy crap! if you like NA KA READ THIS

[rsmithdrift]

So i've finally got the car fixed and running right again (the fuel pump had gone bad so I replaced it with a walbro) and set the timing back to where I like it (25*) and decided to take a test and see what she's got now that she's runnin like a champ again. OMFG!!! This car has so much power now it scares me to death. And some of yall might remember how I drive so you see how crazy it is for it to scare me... If you don't just look in my sig. It's a 3 lane one way street (fresh pavement and flat) and it was empty so don't start flaming.. Anyways I let it warm up and pulled onto Terrace, Dropped 1st at 3krpm and had to let off the throttle to slow down the wheelspin. Shifted to second and it caught so hard it spun both rear tires hard, broke sideways, and I had to let off the gas to stop the wheelspin to gather it back up again. I've never felt so much power in an N/A 4 cylinder before.

I roughly timed 0-60 with a buddy in the pass seat using his cell phone stop watch and it was ~ between 5.5 and 6 seconds average. He hit start when I dropped the clutch and stop when I yelled 60 and let off the gas at the top of 2nd gear.

So I have no idea how much power it's making but if I had 155 before when I first got the car I'd say I'm in the 180+ range now. I stay right on my buddies 89 SR20DET 240sx a** like it's nothing. We are door to door. And his car runs correctly and has alot done to it and makes 13psi intercooled. He's baffled and wondering how he can make his car run as well as mine does now. I've got him going to get a compression test done tomorrow now he's so baffled by it. He thought his car ran perfect untill then.

So cause I know you'll ask if I don't tell you here's what I've done to the car...-248/232 cam swap (ignition timing set to 25*)-Walbro 255lph fuel pump (the key to this cars success)-300zx TT fuel filter-Ebay short ram intake-Magnaflow Hi-Flow catalytic converter (California CARB Legal) OTHERWISE STOCK EXHAUST!!-Removed Fan Clutch and wired the factory electric fan to run constantly with key ON-Cut yellow/green wire to remove speed governor-NGK plug wires-OBX Narrowband 02 A/F Ratio gauge-Removed AIV-Removed A/C-Removed Butterfly Valves from upper intake manifold-Removed EGR-Removed Evaporative Emission System + Charchoal Canister completely

-Other important engine stuff - Car has new 02 sensor, MAF, CTS, TPS, FPR, Injectors, fuel filter, Coil, Cap/Rotor, NGK wires and plugs, ROYAL PURPLE 5w-30 Synthetic oil and I only run 89 octane. (That's it engine wise)

*Edit* Forgot to add... With this setup my car torque curve increases smoothly and gains HARD from 2500 to 4000 then gradually continues to gain all the way till it's peak power at 6800rpm and only falls off marginally till 7k rev limiter. IT IS BAD a**. Especially compaired to the factory tune falling on it's face at 5800... nissan failed with the factory set up IMO

Other stuff done to the car:-Megan Street Coilovers-Ebay front and rear strut bars-Ebay drift/turn knob-Pioneer head unit and Sony 4x6 front/5x7 rear speakers.-Removed spare tire and tools-Removed rear windshield wiper-FULL INTERIOR(that's it... seriously)

So seriously, IDK if I got a fluke KA24DE that just makes ungodly like horsepower or if this is just a combination that works but I'm incredibly satisfied with my horsepower right now considering that it's NA. It's WAAAAYYYYYYY faster than it was when it was stock. I can't imagine what it'd be like with a SAFC II, 248 exhaust cam, and 3" cat back exhaust on it. ... OR a t3/t4 turbo kit to go with that and high flow injectors. Now that would be crazy if it ran tuned as well as it is now...

Anyways, I wanted to give yall lookin for cheap power a N/A setup that DOES WORK

I've got MAYBE 300 bucks worth of work done to that engine. The cams cost $20 from a junkyard, the fuel pump cost $90, the intake cost $33, the cat cost $100. the the rest of it is just stuff you can do at home for free or just regular maintenence items.

IDK what else to say, I'm speechless now. opinions welcome...

*Edit* I made a video of it doing 0-60 in 6 seconds. Go to this thread:zer...conds

Awesome man!I haven't seen you posting much these days.

You should get it dyno'd and switch to higher octane gas. I'm really curious how much power you're making.

[rsmithdrift]

I haven't been posting much because my car has been nothing but problems for the past 2 years because of that fuel pump going bad. I wish I'd of just replaced it first like I wanted too. I feel like such an idiot for saving it for last... lol.

+ I've had some personal problems that have severely limited my internet access this past year or so.

But I'm back now. I love my car.

[Razi]

Sweet. I remember watching some of your videos way back when, before I even had a 240sx.

6 seconds 0-60 times is near 350z territory, I'm really curious about how much power you're making.

Btw, I'm not too familiar with the cam swapping, but the 248/232 swap is done by putting the S13 exhaust cam to the intake side and S14 exhaust cam to the exhaust side and rotating the 232 cam counter clockwise 4 teeth?How's the idling?

I've been reading a little bit about it to squeeze more power out of my KA-T setup, and has caught my attention.

[rsmithdrift]

Idle's f***ing perfect. And you can do it that way but it's better to take an s14 exhaust cam for the 232 that way it lines up perfect. You just have to rotate the s13 exhaust cam (now intake) 4 teeth to make it line up.

248/248 would be ideal if I had 3" cat back exhaust as it would provide for more top end horsepower as would the exhuast and with a minor adjustment to the ignition timing you'll make even more power through the whole rpm range. And since you're KA-T that would def. be the way for you to go. Just get another s13 exhaust cam and replace your intake cam with it. It'll help spool your turbo a little quicker that way too.

awesomeee thread i like!!!

damm i was goin to remove alot of those thing that you have and now its offiicial

good work

[TuRbOS13]

If ur making that much power NA then i'd deff keep it NA. Having that much "safe" power sounds awesome. And you won't have 1/10th the problems as a kaT. Throw some crowler cams in there and forged pistons...ur good to go Good luck and hopefully she lasts awhile like that!

[Ajax]

Congrats! I went the expensive route when the bolt-ons weren't doing it for me. Keep it running strong and post some dynos!

[TuRbOS13]

Wow I should really start paying attention to the dates of these posts. This thread is almost as old as me!

WTFM8??? What are you talking about I made this thread 2 days ago... So you were born in the dark and it WAS last night... ok. I get it. lol

[TuRbOS13]

Haha my fault dude, didn't even realize I left that comment on this post. I had a few pages opened....commented one from 2006 thinking it was recent. Lol good stuff huh

[zerepdivad]

Hit up the 1/4 mile and see how you do.

Well it kind of was. I guess my pumps been going bad since the day I got the car but it's WAY faster than it was when I got it in stock form because of it. And for the last 2 years the car wouldn't even run right because the stock one was going bad. Replacing that fuel pump was the single greatest thing that ever happened to my car.

Gas mileage has taken a dump on me now though. 20mpg max. lol.

[motoman399]

hey with that cam setup did you make an adjustable timing gear? how is your mid and low power? i put that setup in my buddys car a while back and has gobs of top end power but nothing till then. but his ignition timing is around 18* maybe ill advance it a bit see if that helps.

Nope. Just stuck em in their and let er rip. You may be a tooth off over advanced. THat's what it sounds like anyways. I did that at first and I couldn't even drive it I had such low power till 5k... Set em right and yeah, huge difference.

My car has good power from 4k to redline. And it doesn't bog till then either. it feels stock till 4k. It's perfectly daily drivable. If I set my timing to 18* i'd have so much torque from 2500 to 4k it'd be stupid and i'd loose significant power in top end.

[motoman399]

so you set the 248 cam on the intake side 4 teeth counter clockwise? cause thats how i did it and everyone on the internet. i saw i think one person doing it 3 teeth but more were 4 teeth. thanks for the reply

[rsmithdrift]

Yeah I think it's 4 teeth. IDK honestly. I tried putting it in 4 teeth over but somewhere along the line I lost my mark and got it all wrong and had to guestemate at it. I got it wrong twice before I got it right. lol It wasn't fun

[wa-chiss]

*Snicker* Fuel pump being a key to it's success...With that line I discounted everything else in your post.

-Walbro 255lph fuel pump (the key to this cars success)

THIS cars success. Not all KA's. Just his sense the pump was the real problem he couldn't make full power.

[meathead780]

where do you find the wire to clip the govoner?

[mattaltima99]

That KA is awsome!!! very nice work. im rebuilding my KA24DE and was wondering about the removal of the butterflys. so all you do is take them out and plug the holes that they left with a weld or glue "jb" maybe?? and if done properly, does it idle funny or run weird, or does it even know its gone? thanks

All you do to take out the butterfly valves is unscrew them from the rod that rotates them. No holes to plug. And it idle's perfect. You have to remove the vacumn system from the back of the engine though to do it properly.

[*240s-ex*]

wow thats nice! hey send me a PM i would like to talk further about it!!

[skinnyslide]

the walbro pump is by far the best low buck mod you can do .
my set up is 248/248 @4teeth modified butterflys(did away with stock vacume valves and crap and t into fpr so that the butterflies open @the same rate fuel pressure rises) long tube cold air long tube 4-2-1 header 3"test pipe 3"catback 11lbs chromalloy flywheel stage 3 clutch 1peice alloy driveshaft vlsd sollid motor and transmission mounts 10.2 wires ngk ir plugs timing @ 20 deg walbro pump coilovers

my car spins thru 1st 2nd and barks 3rd hard...even gives a lil scurp into 4th i would put money on my car putting down sr power
biggest gain i got came from the wabro

[mattaltima99]

Thanks man really appreciate it. my KA is almost done.

Yea you would have to run that cam set up a little retarded witha good exhaust set up to get themost power out of it. You're probably putting 200 to the wheels... and that is stock SR power so I believe it. Removal of power steering made a noticable difference too. Parasidic drag reduction and wieght reduction.

[tre4s13]

I've tried 240/240...but the 248/232 is confusing....where in the hell do I set the distributor initially?!?! I've tried 0TDC 20BTDC 25BTDC and its just looping (normal?) 645-1k+rpm?!?! Help me out please?

[tre4s13]

It's confirmed....damn motor pulls like a donkey on fire!

HKS Hi-Power exhaust
Egay CAI
248/232
Stock inkectors/fuel pump
25 degrees BTDC
ALL emissions deleted except o2 sensor and muffler



Idles smooth like a brazilian waxing.

[-RJ-]

Damn I need to find a 232 cam for my s13

[asoomal]

So doing this.
