Hi am fairly new to the world of the 240sx so i have some stupid questions.

First off i have had several people tell me that my ka24e can make about 300hp for about the same price as swapping in an sr20. is this true? and if so how would i go about doing that? i have searched the forums and not found any helpful information on that.

my target is about 300hp n/a can it be done? if so how can i do it? thanks for your help.

Swapping for sr20det=3500-4K

300HP on a NA=5000-10000

Under 3k you mean?

Well...without turbo charging....you wont be over 250hp for anything cheap my friend.

unless you use NOS

How about a price range to make it to 200 hp n/a at wheels??? (no nitrous oxide)

ok i'd settle for 200 at the wheels then maybe a turbo and n2o later. i am just looking for somewhere to start.

for starters you should buy my hotshot headers and injen intake. :) if you're planning a swap don't waste your money on the ka though.

for 200 at the wheels you'll probably have to increase your compression, do every bolt on, port and polish, and i'm sure there's other stuff for around 4000. http://www.afterdark-tuning.com/ka24.html has an na build up.

Hahah, you wanna let me know where I can get a full SR20 swap installed for 3,500? Yeah, didn't think so. The LEAST you'll pay is 4k, and that'll be a COMPLETELY stock setup, without even exhaust or intake. And that'll run maybe 190 to the wheels. You can get a Nsport stage 1 turbo kit for $4k (not installed) and you'll run 250 to the wheels.

Personally, if you were looking for a weekend warrior, get the turbo kit. If you want a daily driver that is still very reliable, but not nearly as fast, get the SR20. Remember, the legality of an SR20 is a big issue, and they rarely pass emissions. But then again, I don't think turbo'd cars do either.

the legality of a ka turbo is also an issue. ka24de is epa approved, but not the ka24deT. I think if you want to get to around 400hp go with the sr, you'll have to buy a new turbo kit but you probably won't have to rebuild the internals. otherwise its a toss up. ka turbo will probably be cheaper to around 300 hp. it depends on what you want out of your car. as for the sr you can install it yourself for around 2500, ka turbo will cost around 3700 without install. and 250 to the wheels seems a little high for the nsport kit. maybe 230-240. i guess it depends on the car's set up. without exhaust though it'll obviously be lower.

my target is a daily driver with about 300 Hp... i am trying to do this under 4G (i think it can be done). i have all the time in the world to wait and look for parts... also i live in NE no emissions regulations.

I feel that atomos, my target is a daily driver w/ 200 hp to the wheels for under 3G. dont know if its possible but thats what I want

Hey zebrahead, I hate to be so detailed but the nsport stage 1 kit only produces 240 at the wheels. But still the you can make your ka comparable or better than the sr.

and doctorj240, wouldn't you agree if you put a high perf. cat. that guarenteed to be meet epa standards that it would pass the ka-t through emissions, not to mention you could turn the boost down.

I'm almost positive that a high flow cat would still pass emissions as long as its warm enough to actually catalyze. Turning down the boost to 1 or 2 psi will help too. I think the nsport kit removes the EGR though so that may be a big problem in emissions. I've heard of plenty of turbocharged cars passing emissions though. I'm pretty sure that even if you pass emissions it still won't be a legal engine.

that depends on the quality, and waffering, of the catalytic converters "waffles"/ strainer thigies. a random technology converter, or reputable brand should be fine, I ran one on my 300ZX, and it actually made my emissions far lower than when my stock one was in(it was old...), and passed easily.

as far as costs go, we discuss the KA-T and sr20 costs quite often, and all I keep telling people is that the KAT is the way to go for "street" horsepower, anything under 300, the KA has an advangtage, but reaches a rate of diminishing returns after 350hp, where the SR20 begins to take over the HP/dollar ratio because of the wide aftermarket for the engine.

as far as 200rwhp in NA trim, thats gonna cost you man. basic "I/H/E" will not evne come close. I have more mods than most people I know of(see my profile on the 240sx' over atlanta page) and run 140hp and 150lb/ft to the wheels.

headers might add 5. the intakle I go put in after the dyno, maybe 2.

anyways, your talking running higher compression pistons, cams, cam gears, and ECU tuning to get to the 200hp level. it will probably cost a little less than a turbo kit, but the turbo kit offers far more HP, and open the doors to more mods.

don't think its possible to get 300 on a NA ka24de...for a 200 NA ka24de you'll need every bolt on intake exhaust header pulleysand you'll need alotta internals port/polish heads, angle jobs, some CAMs (so so I have heard they are helpful)take it to a reputable shop to have engine balanced and rebuild that'll be ALOTand there also a racing clutch and a lightened flywheel to help translate power to the ground......... don't think its possible to do everything under 4k unless you do all the labor yourself

I think it's possible to get near 300 NA with race gas, wild cams, wild timing and fuel curves etc. But then you wouldn't have a street car you'd have a race car only. And that kinda sucks. Like I said earlier though, go to afterdark. The buildup is a really good deal.

Getting 300hp to the wheels with 4grand is impossible. Getting 300hp to the wheels N/A is impossible.

But getting near 200hp to the wheels with 4grand is possible.

"Getting 300hp to the wheels N/A is impossible"

negatory, with enough money, anything is possible. what you meant is "cost prohibitive"

There are hondas making over 300 to the wheels NA. I think its possible to get a ka to 300 hp or close. In no cirumstance will it be cheap though. 200 to the wheels for 4 grand is very possible.

well, yeah, you know what I meant. :)

Its impossible for the average joe to fund his project to get to 300hp N/A.

And as for the Hondas getting to 300HP, how much $ did they put into the engine? And how much time and effort?

well, last I saw my friends 260hp integra GS-R had the following(estimated costs..)1. Headers, cat pipe, exhaust- 900 dollars(conservative)2. AEM CAI intake- 200 dollars3. Cam gears- 180 dollars4. intake manifold, throttle body- 400 dollars5. Cams- 300 dollars6. ECU controller- 350 dollars7. port/Polish manifolds, head- 800 dollars8. valvetrain internals- about 200 dollars?(no clue here..)9. Fuelrail, FPR, injectors- 800 dollars10- bottom end egnine rebuild(High compression pistons, forged rods, etc) 1800 dollars

this is without labor, guys. total estimated cost:$5,930 or about six grand. more liekyl, with installation, about 8 grand..maybe more!

so you'r looking at the cost of a NICE turbo setup for that kind of money, rgardless of the engine, my friend didnt want to use any boost("cheating" he calls it), but he realises how much thtis **** costs...
