S13, stock basically. KA. Which is better to go with? Turbo or Supercharger? I wanna daily it, but also have good power/reliability.

EDIT: let me edit this, cuz you guys are dbags. I have 4000 dollars I'll dedicate to upgrades. Let me be more clear on what I want. A decent amount of power. 300ish. Reliability is a must. It's my only car, I don't want it to break repeatedly. My question is: what is a better option for up front gains, reasonable cost, and decent reliability. If neither is a good option, list me some upgrades I might consider. Thank you.

I appreciate the seriousness in your answer. I literally just wanna learn more, and get some good options.

WillFreeZy

Thanks for the great honest response. I've learned so much.

Assuming you're 16 or something, it's easier to find and put together turbo stuff, but you're going to blewed up your KA if you buy cheap stuff

Nitrous is what you need

1. I did search, couldn't find what I was looking for. You know, there's a million posts on this site.
2. I wanted to use this site, because I was under the impression that this website was for s chassis vehicles, and discussion about s chassis vehicles. I had imagined that there were some actually experienced s13 owners/workers here on zilvia.
3. Certainly
4. See #2

Thanks for all the help. I'll remember what a shitty site this is.

What the fuck is a reliable 240?

mewantkouki

Best advice would be to leave it alone and drive it. It's a 20 something year old car, it's not going to be reliable under the added stress forced induction will generate.

5280VertDET

Buy this:

LESS THAN $4000 Too!

The key to reliability is really keeping the hp figures low. A stage 1ish turbo kit will prob be your best bet. Bottom mount manifold, t28 or similar, internal wastegate, sr20 injector, etc. I like the idea of the SC'd ka but it will require fabrication and some of the parts can be hard to find.

If you have $4000 to spend, I suggest buying a daily first. Once you get your daily reliable, then start dumping funds into the car.

We all know there is that time when you're working on the car, something goes wrong and you'll end up needing a part to purchase locally or wait until the part comes in.

I really appreciate you giving me a real and quality answer. Thank you.

to the original OP... youll have to understand that Zilvia has turned into a shit talking fest, especially toward n00bs who ask simplistic questions. dont get disheartened by the ramblings of a few people that choose to reply, but heed in what older members are trying to tell you. searching is a powerful tool, especially since Zilvia has existed since the early 2000s and will 9 out of 10 times contain the answer you need if you spend more than a few moments searching.

also, if you have $4000 to dedicate to upgrades, i would highly suggest a clean, low mileage (yes they still exist) SR swap with good compression. my first SR got me thru college and lasted well there after! if you MUST keep your KA *shudders*, piece together a QUALITY turbo kit (you can still find S15 turbos brand new for roughly $900) using higher quality parts. tuning on the KA is ESSENTIAL as well! you will need to find a decent stand alone for your KA... if you want to keep the KA reliable, dont over boost the crap out of it. 10psi on an S15 turbo will be about as far as youll want to go on a stock bottom end to ensure reliability.

in all honesty though, take that $4000 and buy a daily driver, then slowly save for building your S-Chassis over a period of time. the daily driver will ENSURE that you have a reliable car to drive around in while you tinker with your S13/S14.

When I said it was my only car. I meant it was MY only car. In the event something goes wrong, I have another vehicle available. I should have specified that.

You're very welcome!

As suggested, please use the search function and read. Sure, there are a shit load of thread out there on all of this material, but it is a wealth of information.

There isn't a simple answer. There are many factors to consider, age and mileage of said vehicle would be the top of the list. What are your goals? You didn't supply much information, just a bland question of which route to take.

Now that you have supplied more detail, a basic KA-T is all you'll realistically be able to afford.

If you really searched you would've found the same info I know now.

I have an S13 KA24DET in my kouki S14. (I blew the seals of the first motor within a month of installing it)

KA-T is the normal route. I would recommend a rebuild (at least pistons with new piston w/ new rings and maybe valve guides)

Supercharger is not a good option for the small motor because there's no way to cool the charge coming in, it's not that efficient and tuning options for it are slim.

People typically use Xterra superchargers.

This information is available EVERYWHERE if you look. Seriously Google it and draw your own comparisons. This is what the other members meant when they said they don't want to spoon feed you.

I never asked for info about the two things. My whole inquiry was about which was a better option. Do you people really think that I didn't search and read things? I asked a simple question. Only one person gave me a real answer. So much angst and attitude came from my simple question. Extremely toxic environment. I never asked how to install one or the other. I never asked what one was. I never asked for specific models, and numbers, and methods. I asked which was more appropriate for me. How am I supposed to decide if one is better than the other, without having people give me their own experiences? That's what I wanted. People to tell me how it went for them, and which one would be better. I can google search something all day until I have a phd in details. That doesn't help me know which one is more applicable to me, and what possibly could work out better. It's crazy that I use this site for what it's for, question and discussion about an s chassis, and get told to go search somewhere else. That's real great.

Go turbo. It's not worth your time to try to get your hands on the supercharger kit. I tried contacting the KA24DER guy and even told him I was ready to buy and there has been no response. This guys for many other people as well. Cost or R&D to duplicate his kit will leave you with nothing in the end to do any type of ECU tuning. Right now with things like the tomei kit being almost complete, it's just easier for you to do turbo. That way if something goes wrong, you have only one company to blame and try to get things warrantied.

FaLKoN240

You can write wall of text all you want. Your question has been answered. Go turbo. With 4k you can rebuild your motor, get a decent manifold, turbo and tune with a z32 maf and some larger side feed injectors.

There you go.

The way I would turbo a KA:

Rear mount oil-less cartridge, automatic trans

You can go for stock engine 250hp or 500+ if you build the engine/trans. Point would be... nobody would see it coming (pop the hood and nothing there, just stock, painted black intake that sort of wraps around and disappears)

"hey where does that intake pipe go?" -> "to a cold air intake filter". Kind of true, just leave out the turbo part. "ya dont see any oil line going to the oil pan do ya? It ain't a turbo..."

Dats sneaky lol

When you provide all the details up front you have a higher probability of getting the info you need.

Dedicate $4k to a running car that already has the power so you don't have to be a burden on anyone else.

I'm a dude, medium build. 165lbs. Which is better to go with? Hamburger or burrito? I wanna eat it, but also enjoy great taste.



another huge detail...how many fucking miles does your car/engine have? is it even in the right condition to be taking air that is at a higher pressure than the air that is being inhaled/exhaled through your mouth?
