youd have to have deep pockets to get more than about 200 without a turbo, and even then the max youll get is maybe 260 or so

its a 4 cylinder engine, it needs a turbo for that much

NNNAAAWWWSSSS.

or any engine that comes stock w/ 300-400hp... ford/chevy long blocks come to mind.

You'll spend less money and waste less of ppl's time if u sell your s13 and buy a camaro z28 or something.

oh by the way since now you changed your mind and ur gonna go turbo... hmmm just so you do know the block wont handle 300-400hp, so re-do the block forged everyting, go turbo, and make even over 400hp near 500hp.! no lie. its been done.

and never try going n/a on a KA. it sucks.

Well. I'm on a 1,000 dollar budget to increase the hp on my 240. Right now it's stock motor wise. I only have an elect. fan and NGK plugs and wires.

I'm trying to get enough power to be able to be fun and hold a drift on dry pavement. I have future suspension and LSD plans that total about 1,000 bucks also. That's a 2,000 dollar budget in total. I want to do the power stuff and sway bars first. I just want to know what my best rout (sp?) is and what hp I can expect from an N/A ka on a $1,000 budget.

If I can get 180-200hp I'll be happy.

nope

heres what you do:

intake, exhaust, header

that will take care of your $1,000, and get you another 15 or 20 hp

cams are another $600, and theyre the next logical step

155 + 5hp (fan) + 5 (intake) + 7 (exhaust) + 5?? (header) = 177 ish. Not too bad. Granted that is flywheel hp not wheel. Prolly 140-145whp right??

How does intake and exhaust = 1,000?? Intake is 40 and cat back is 400 at most. How much is a damn header?? jeeze.

youre not getting 5 from a fan

you really cant just count them like that, theyre all different

and its wheel hp that matters anyway so yeah, probably 140 ish, maybe 145 if youve got a good engine

if you say you would be happy with 200rwhp then do this.... turbo the stock block, 8psi, the internals will handle it, get a decnet turbo to get you to 200rwhp.. 14b will work fine, upgrade your fuel, tune it, and your make 200rwhp maybe even near 220. and also stripped out the back end, back seats, stripped out the whole hatch and your get the sucker drifting on dry pavement.

its very cheap.. you can turbo the ka for like 700 dollars, its been done, by the jordan guy on ka-t.org.

my setup for my ka24e to just make 200rwhp is the 14b turbo, ported out turbo, and rebuilt, dsm injectors, walbro fuel pump, stage 1 xtd clutch already here and installed, but soon gonna upgrade to stage 3 xtd (just becasue i need a stronger clutch), and a stage 1 camshaft. thats gonna be my setup to make 200rwhp, tune it good, retard timing some and you'll be set for daily driving as long as you don't be reving the piss out of it.

youll need a BOV, wastegate, some way of tuning for that setup

manifold might help too

8 psi doesnt = 200 rwhp

i can make 300 rwhp at 8 psi if you want

its all in the turbo, the psi / power ratio is dependant on the turbo

yeah well i know bov, wastegate and all the other stuff, but i was thinking the thread-starter would of gotten my point thats why i didn't list that.

thread starater if you have a ka24de i suggest you rread this

http://www.ka-t.org/forums/vie...light=

and buy all the parts and do the same stuff this guy did and all his turbo parts cost him 704 dollars! thats cheap! you'll even have a lot money left over for a good clutch.

I have a 93 fastback SE. I went out looking specifically for a 91-93 fastback SE for the way they look and the DE.

BTW, I was talking flywheel hp. I have a bad habit of disregarding rwhp. 155hp = 120rwhp usually so I'm thinking 200hp = 160rwhp or so. 150rwhp would do the job IMO. Hell Taka Aano drift with 160 hp and does fine. He even has high performance tires so I think 150rwhp would be fine in a car with $25each used rear tires. Also the LSD I was talking about is a welded diff. :P

Anywho. I really don't want all the hastles with turboing a non turbo motor. If I could afford all the other expenses I would go KA-T in a heart beat.

dude!!! all the hastles with turboing the ka is becasue its cheaper than n/a and is better than n/a and n/a sonds like butt hole. like you said you only have a 1,00 dollars, and nismofly just posted that you won't do intake, header, exhuat, cams and tuning, for a 1,000..

so i would do the turbo idea if i were you and if i had 1,000 dollars. its 704 bucks and you have a damn ka24de, it'll be soo easy. and hell your even have money left over to buy the damn high peformance tires probably and a clutch.

you gotta read that dude's post on ka-t.org. he's a ka turboing god! he's the best at what he does, i mean dude stock ka24de, cheap turbo kit, 704 dollars, 7 psi, no fuel magment, runs 94 octance pump gas for the past 2 weeks and posted he has no problems so far.

turbo is your best cheapest bet if all you want is 160 rwhp and i think everyone will say the same.

Nismofly is right, 1,000 dollars wont do it, and it'll even cost you a lot more money to get all the n/a work you want to make 160rwhp, so it's really not worth it if n/a work is gonna cost more than a cheap turbo kit.

LOL i used to think like you when I got a 240, i was all about the n/a at first, i've done it and i gotta tell you it really sucks, i wasted a lot of money on n/a too and wasn't even happy with it.

i wouldnt say NA sounds bad

id love a carb'd sohc ka with a 288 / 292 cam in it, that would sound better than anything

the reason i go turbo is because after the initial cost, its relatively inexpensive to up the power in heaps

i dont know if id want $700 worth of parts for a turbo, jordan probably did a lot of custom work to get all that stuff working good because he can, metal work and stuff

i plan on running around 270 - 280 rwhp, for around $3,000, but ill have everything, im not cheaping out...i figure ill do it right the first time so im not one of those people that is on their 6th or 7th engine because they keep trying to cut corners

if youre counting pennies to pay the bills just leave it stock, throw an exhaust on because youll be able to use that when turbo, but leave everything else for now

you have to remember that setup is non intercooled, if you want more than about 180 rwhp youll need an intercooler which is another 3 or 400 right there

theres a lot of bits and pieces to consider, itll all add up in the end

at least youre not the person saying i want 500 hp for such and such, because you cant have a budget at those levels, just doesnt work...well, unless you enjoy having your car sit for 9 months a year

lol. You crack me up.

Anyways. I am not a pro at installing things. I am very mechanically inclined but installing a turbo sounds complicated and WAY too much work for me on my own. I can do intake, exhaust, cams, etc. But installing a turbo?? I'm scared just thinking about it. Wouldn't I have to tap a oil feed line and a boost gauge and some sort custom intake track and wouldn't I still need a header and downpipe??

I just can't see myself doing all of that work. I'm thinking I'll do the suspension stuff first and do a turbo this summer when I have the time to do it all at once.

I was origionally planning on modding slowly. Like doing intake one week. Then a month later doing stabilizer bars, then a month or so before springs and struts. Then doing exhaust some time later, a few weeks before going into header, etc. I'd have to do this all at once and that's one hell of an install.

Btw. I have a new clutch. Though it was put in by the previous owner 1,000miles before I got the car, so I have no clue what kind it is. It's only 3,000miles old now.

suspension first is always a good idea, brakes too

and btw you dont need a header, for this its called a turbo manifold

but yeah you will need to do a lot of stuff you listed, its just a ton of work

welding the oil pan bung and stuff like that im not going to enjoy, thank god ive got 3 people helping me that have a lot more experience, one had a 430 rwhp ka-t and one had 550 rwhp

as far as the clutch, any more than about 200 rwhp and itll be worthless after a short while, if its stock that is

im going to have to say theres quite a few things easier

not hard no, but just a little of little things you have to do

im one of those people that cant stand having to do 300 little things, i like just being able to bolt it together and go

for the most part thats what a turbo install is, but all those little things get on my nerves
