turboing my 240sx (ka24de)

[bsilvias13]

hey guys i was lookin to get some info on what you guys may have used before as far as turbo kits go. i know that going cheap is not the BEST thing to do. ive talked to AMS Performance and they have told me that as long as the KA passes compression and leakdown test ok that the ka can handle 300hp on stock internals now please keep in mind im not even lokking for that much.
heres a list of what i want to get out of it.

1)i want it to get good gas mileage when driven regularly. (250mile to the tank.)
2)on low boost i want 225whp and on high i want 250 to 275 but atleast 250whp on high boost.
3)i dont want to swap it for an sr so dont tell me SWAP IT! thats not the answer i want if im gonna swap its gonna be for an rb26 NO QUESTIONS ASKED.

I would do the following:
eBay KA T25/28 Bottom mount manifold
SR outlet
SR down pipe
New S15 T28
S13SR FMIC kit(fits both S13/14 KA)
550cc side feeds
Walbro Fuel Pump
Nismo FPR
AEM EMS

But, that's just me.

this is the easiest and cheapest way to go. this is a pretty safe setup as long as its tuned right.

There is tons of post on this already, and S14DB's post looks to be about 4grand or more.

i'm guessing if the guy doesn't know how to set up the turbo, he doesn't know how to tune an EMS. or at least add a wideband.

I kinda hope he's going to a shop.

Till the internal gate starts to creep and then you flow too much...

[OBEEWON]

I have friends who have blown thier KA-T's with less than 250hp, I blew mine with 170!!

I honestly would spend the money on building it before I boosted it. But Im the type of person who likes having peace of mind. Others may argue the nessecity of this.

But as far as kit goes I would go with what S14 DB said only I would use a Disco Potato, and a Rom tune with a SAFC.

Hope that helps a lil bit.

If you blow a KA with anything less than 12psi, you tuned it wrong or abused it.

I was thinking the same thing............

[Dream240]

Okay, I have yet to get into the turbo aspect of my car, (still learning turbo 101, 102, 103, etc...)

Here's a question: When you guys talk about "tuning it wrong" you're referring to the A/F ratio, boost pressure setting, and timing, right? I mean really is there anything else you have to worry about when "tuning" a turbo setup?

Thanks for the help in advance.

Oh and feel free to flame if you're in the mood I dont mind.

Bingo. The basic setting is A/F, running it ragged lean will detonate like a son bitch, which is how 99% of engines die when run hard. Ignition timing, cam timing, boost pressure, all fall in that list too of things to set. The idea that you just a throw a turbo at a car and drive it like you stole it is stupid, yet people continue to do that because proper tuning takes time and money, something the 16yr old kid who's trying to impress his friends doesn't have.

This is true. That why I like swaps because you have a larger margin for error, and you can abuse them, but on the flip you can replace a KA for next to nothing. 6 of one and 1/2 dozen of the other I guess.

[ownnij]

thats the point man, why would we wanna drive something that has more of a percentage of blowing up. no ones perfect and will make a human error. if its just that much power your looking for just swap your motor man, if you do it your self it'll be cheap. s13 motor with sidemount

You can't read. There's no higher percentage with anything. Buy an SR, turn it up to 14psi on the stock sidemount, and listen for the knock, because it's there. Anytime you push an engine's limits, whether it's already turbocharged and fitted with forged internals or just a stock Mazda 1.6L you're walking a fine line. Tune it properly (and safely) and it will last forever. If you beat on something hard enough it will break regardless, so if you don't trust yourself to not blow it up then you need to find another hobby.

[punxva]

also check out KA-T.org

I would do the following:
eBay KA T25/28 Bottom mount manifold
SR outlet
SR down pipe
New S15 T28
S13SR FMIC kit(fits both S13/14 KA)
550cc side feeds
Walbro Fuel Pump
Nismo FPR
AEM EMS

This is basically what i'm running, minus the EMS which in it's place im running a SAFC 2 and stock SR injectors

as far as the tuning aspect, they are speaking of the A/F ratios, and timing, which are vital to keeping it running smooth and strong, I'd also reccomend getting a wideband to keep an eye on your a/f ratios, and it is a def plus if you plan on tuning it yourself

[Jung918]

I would go with a manifold with a T3 flange as it will give you wider options of turbos in the future.

what will the car be used for?
there is also the option of the thomas knight supercharger kit.

an s14/s15 t28 sounds like it'd fit perfectly with your hp goal although it doesn't leave you with a lot of room to go beyond if you decide to up the power. if you plan on sticking with mid-high 200's then you're good to go. all i can say is play it safe and give yourself some wiggle room in terms of fuel and tuning. safe and conservative is the way to go.

as for mileage, i was doing around 280-300mi per tank and that was with mixed city/freeway, grandma/lead foot driving.

[EDacIouSX]

yea basically what they said about tuning. I plan to go with a t28 but im guessing the most reliable and safe bet is the greddy kit since it already comes with the emanage and is tuned... But, I'm no expert all I can really add to this thread is the

Importance
of
tuning!

It's very important.

[S14DB]

Still a Piggyback solution.

[projectRDM]

Still $1000 cheaper. You forget who you're dealing with, these kids own 240s. $100 for a manifold is already out of their parents price range, there's no way in hell mom and dad will allow a budget for a standalone.

[mRclARK1]

If you blow a KA with anything less than 12psi, you tuned it wrong or abused it.

Tuning is the difference between a modified, fun, and (as much as moded cars can be) reliable ride... or a big heap of metal.

[sunnys14]

fuel control is easy (safc2) but timing is THE MOST important. atleast get a msd btm to retard timing while in boost.

You could just go w/ a Greddy kit. It's got everything you need for the horsepower you want. You could get the entire kit for around $2600. Just get an intercooler & your set.
I know there are other kits out there that might be cheaper or piecing it together. I'm only giving you another option that is convenient (complete turbo kit in a box basically).

why not just buy all the parts seperate? it's not much different and you can actually get all the things you want for your specific goals...somewhere it's posted on the output of the greddy kit, but IIRC it's like 175-190whp at 6-8psi of boost w/o IC and with an IC you are closer to 205whp at 8 psi...

isn't the turbo on the kit too small to boost the ka to 275whp? a t28 other medium/larger t2 would be better IMO...or a t3 if you would like to eventually go even larger, but for what the OP is asking a t2 should cover all three of his wants/needs and be cheaper unless he eventually upgrades then a t3 would be cheaper in the end.

do what you want, but I've heard complaints about greddy emanage...rom tune + safc for fine tuning seems like a better bet

[klohiq]

I was thinking it would be pretty close to maxed at around 250whp...guess not, never really looked into it since a t25 is so cheap if I wanted to make my own kit...
