450HP out of a KA motor?

[180sx2nr8u]

I've been thinking and I was wondering if 450 hp out of a KA motor would be too much (or too little) for a daily driver/weekend drifter? would i have to fortify the bottom end in order for the motor to handle that much, or will it be ok? a friend of mine said that 450 out of an SR would be nothing, but i dont really want to swap the engine (what with smog and all). someone tell me if my thinking is right and give me some tips. I appreciate it.

well as a general rule of thumb, driveablility goes down as power goes up... 450 is quite a substantial amount of power. i'm learning to drift in a volvo with a tad over 100hp. think about that for a while.

[180maniac]

if 450 hp is not enough power for your daily driver you must be on crazy mofo. to get 450 out of a ka you would have to fortify everything, i saw one ka-t with 401 hp and his list of engine mods was like 10 lines long. and i don't know who your friend is, but 450 hp out of an sr is definitely something. i suggest you do some looking around, most peoples on here have cars with barely over 200 if even that. if you wanna know about getting power out of a ka i suggest going to NissanInfinitiClub.com it has a forum for ka's then a seperate one for ka-t's. very good forum, but read around some before you post and get some basic knowledge.

- peace

ps- sorry about not using proper grammar, i am too tired right now, i'll fix it later

450 out of either of them is a project and a half.

You seem to think all you're going to do is mail order a few parts, throw them in, tighten things down and let it rip. That's not the case.

[young gun]

go with ka its way dooable and has been done here longer, now the important part, have you ever driven a car with this much power? if not your gonna crash, catch on fire, and die cause its alot. secondly you dont need 450hp to drift an s chasis a stock ka is just fine, thirdly 450 is too much for drift to get the power your gonna have super lag or less lag and nos, its gonn ahave an unstable usless powerband for drift, if your dead set on turbo go for a t3 or maybet3/4 and tune it to like 250hp drive that. it will be fast and easy to drift, i still say stock ka, riliable and cheep 450hp is neither. p.s. sr is not answer to all they blow and crap out too, old motor+sitting for years+poor tuning=waste of cash

[BENJO]

IMO just buy a turbo kit and you'll have between 200-250hp (or so i have heard of) then try drifting in it. after that you could answer this question yourself.

heres a site:

there about the same price of a sr swap but its the best thing you could do if you want to keep it legal.. OH YEAH and im pretty sure that the greddy kit is legal in all states.

[stretch240sx]

450 out of a ka is doable... iver head of a guy getting 358 out of a KA in a race hardbody still NA. but thats a race motor, but just shows you the potential.

but like everyone says... it will be harder to drive if your not used to the power... like now you have to step on it to get the ka up and going... if you were to throw that much power and step on it... youd end up sideways in a heart beat.... try lower number and then move up in the world

450hp? Are you kidding me? You don't need anywhere near that kind of power in a 240SX of any kind.

A KA-t has done 500hp before, but it was BUILT.

For professional-level drifting, 250-275whp would be just fine.

For the street and for play, 230whp (about 7-8psi on a properly set-up KA24DE-t) is plenty. It's also reliable and low-stress. Oh, and in an S13, it requires custom work, so it's not a walk in the park.

What about for auto-x?

I think you guys also forgot about the most important part of building power on any motor. The more power you put out, generally the shorter the life of the motor. You plan on daily driving anything with 450 out of a 4 cylinder and you're asking for reliability issues.

450 out of a KA is possible, I've seen some around 400 before even without the crazy build ups at the bottom end, don't under estimate the internals of the KA they're pretty good, but you have to put care into a water injection system and so on to keep the temps at a reasonable level to keep your motor from blowing apart.

Still though 450 for auto crossing or drifting is still pretty excessive. If you plan on running a turbo that'd give you that much power, you'd have nothing at the bottom end. For auto-x some of those get pretty technical and require you to do pretty technical turns and such. The lag you'd feel from that power would be bad for your times.

[drift180sx]

yea i'm gonna go w/ grid on this one... 450hp is no easy task it is do able but it will take gobs and gobs of $$$ and as for auto-x it would still b hard 2 do. even getting 450 out of a sr20 is hard. everypart of the motor must b beefed up 2 support the huge amount of power. if u want a daily driver/weekend drift machine go w/ the sr20 if its not illegal in atlanta they are wonderful motors and if u upgrade parts of it u will hav one hell of a fun car for relitivly cheap...

[nissanguy_24]

Drop the compression ratio. 450 is going to need a big laggy turbo and lots of boost. This is the kind of power the pro level d1 guys are running with. So i would venture to say its not easy to control.

If theres one thats Carb legal then it would be news to me. I know greddy had one for the S14 that was carb pending. I dont know its status or how that translates to S13 legality.. but in most other states the turbo KA will be more legal then the SR.

[jaydm180sx]

450hp out of a KA!! You must have deep pockets. Both the KA and the SR are capable of 450hp, either way it'll cost you. Personally I feel that 450hp is too much power for daily driving. Like someone posted earlier you should be more realistic and shoot for around 250hp-275hp.

[Scott]

Not only the will the engine need the work, but the rest of the driveline as well.

[my 1 88 u]

If you live in GA it shouldn't be a problem getting an SR20det to pass emissions as long as you have a catalytic converter. There are a few tuning shops in the Atl area that specialize in SR swaps and tuning that won't bust your head with prices.

[defiantfc3s]

You don't need 450hp out of a KA24 because it would cost too much to even get that much, especially if the motor is stock. It would be easier and cheaper just to drop the SR20 and a few mods to it.

[URMachines]

i think we are just talking to someone who just like big numbers and bragging rights.
450 hp is definatly excessive for ANY street 4 cylinder engine. try handling 250 hp and then come back.

[240CATION]

hey the Ka24de is a stable platform to build a 380 to 420 rwhp monster for under 6 G's , mine is a 420rwhp daily driver at 22psi.
I have posted several times on how this is so. I love the car so much I'll do it again.
First off your starting with 2.4L displacment cast iron block (2jz1 toyota supra engine is a cast iron block also) Remember their is no replacement for displacement.
The weak spot on the Ka is the pistons(weak ring landings) even so with proper tuning many avoided that problem by retarding the timing .5 degress for every pound of boost(=combustion on the down stroke).So this is what i did for 6000 G's

It is funny that people want to get 450HP here and 450HP there out of their cars. Have you ever ridden in something with 450HP? If you have, you would realize that 450HP is a pretty excessive figure for a daily driver and for a beginner Drifter. Good god, I lay down 342 at the wheels and it was SUPER hard to keep it under control in a pinch. So to the guy above, awesome. I like it that someone has done the KA. To the masses, think about your figures and the amount of money it takes to get there.

[nissanguy_24]

A better question is have any of them ridden in a lightweight car with 200 wheel horse power? i bet the answer would be few have...

now thats what im talkin about. youd be surprised to fat 200 hp is in a gutted AE86. this is what my friend is doing. im going to help him build his 5ag 20v. hes got a 83mm HKS stroker crank, carillo rods and is waiting to buy some hard to find 5ag pistons.
200 hp is very doable with this setup and will be crazy in his gutted body.
back to the subject, id suggest getting a turbo start at low boost(5-8 psi) and work your way up until you can handle that kinda power.

[GRiDRaceTech]

240CATION- I gotta cry foul on 22psi street-driven. How much lag is there? 1/4 mile times? Dyno sheets? Picture of your boost gauge running at 22psi with a mirror in front of the car and the hood off so I can see the turbo KA?

SMC's way of thinking is right... in a light car, wtf is the point of over 200whp? I know a KA24DE will run 220-240whp at 6-7psi, and that's PLENTY of horsepower to stay sideways or run high 12s. It's also plenty of horsepower for the street and runs the least risk of blowing expensive little pieces of motor all over the fast lane or mid-turn on your favorite touge.

[spinitsidewayz!]

i guess to sum it all up its doable...

its not cheap though
really not needed in a street car
and very unpractical..

especially in a street 240 and it would be hell to try to drift... friends car is sr@300... that thing isnt very nice to noobs like me.. (and not to be mean or anything) youre 15, id be more concerned with learning and researching more about the basics of drifting and such and not really big power numbers...

so much misconception with people thinking drifting requires huge power...

stock ka is good enough

[NismoSigma]

LoL daily driver at that much HP, why? You get like 10mpg on that! You dont even need that much power, why would you, if a 200hp hachi can beat a 700hp Viper, than its all about the skill. If you want a daily driver your prob gonna drop like 10g's in the car and another 1200 a year for gasoline, its not worth it. And your 16? LOL im that old too but I have the common sense to just think how much that would be! Do you have a job? Your friend is prob 16 too so wrong source, just go to www.240sxforums.com IF you still wanna drop your college money on your "hella tight" ride so all the chicks at how much smoke and noise your car makes. Common commen sense please!
