KA24DE questions

I think everyone agress they are both great engines, but KA-T is growing in popularity because people don't feel like swapping an engine when they got a perfectly good one already in the engine bay, I'm sure they'd all be happy with an SR if they had a Silvia.

Isnt that what i was saying? why quote what i say and then say the same thing again....

I guess, I was just explaining a little.

yeah 10 psi on a KA with a aftermarket turbo kit usually would yeld close to 250whp. plenty fast for someone whos never experienced boost.

a KA with a aftermarket turbo kit

As opposed to a stock turbo?

Most aftermarket kits come with T04 compressors. A junkyard or stock-type(utilizing T25 or T3 from other "stock cars") could make anywhere from 200-220whp on T3 or T25 turbos. So what Tat said was correct.

Oh, ok.

I woudln't call fuel pump, injectors or such rebuild parts. Those are considered upgrades. For 10psi depending on the turbo, you should probably at least do a SAFC, 300zx mafs, and 400cc+injectors. I'd go with 550cc personally. Adn definately upgrade the fuel pump no matter what.

How much would SAFC cost and also why do I get a 300zx MAFS? Like I said I'm a newb and I'm not looking to get flamed here so sorry for the lack of knowledge. I have read a lot, but it doesn't answer all of my questions and I don't want to ruin my car. Thx for all the help guyz!

the stock MAFS will max out at some kinda low HP number i forget exactly its probably like 225 +/- ??

The 300zx is capable of metering 500whp worth of air. The stock sensor maxxes out at a low voltage compared to the 300zx. Plus the diameter of the actual MAFS body isn't large enough to flow 60+lb/min of air.

running a Z maf is not benefitial a low boost. however it is required if you want to make more then 230whp. i maxed mine out at 230whp. also since i wasn't much power over the stock maf limit, it ran fine with the SAFC until it crapped out on me. so i upgraded to a Z MAF for later use cause i will soon not need to run the SAFC. as soon as JWT can figure out whats wrong my my tuned ECU, my car will run like a normal turbo car with 615cc injectors and a 500hp limit MAF without any piggy banks.

Would it be ok to turbo without having LSD?

What do you think would happen if you did?

I'm guessing traction problems, but I don't know too much about LSD so that's why I was asking.

You can have traction problems without a turbo as well, all depends how you drive & what you want to do with the car.

Exactly, depends on your suspension, tires, how hard you launch, all kinds of things. I'd say get one, but you don't have to.

you should buy a few upgrades before you turbo. Such as a new fuel pump, LSD, exhaust that works well with turbo application (if you dont already have one), MAFS, large injectors (semi-optional)..ect...

These are all things i would get when im running N/A right before i turbo..

I'd only get the bigger MAFS and injectors once I turbo so I don't have to tune it twice.

How much would LSD cost? I heard it can be pretty expensive.

Some of the parts i listed i wouldnt install when i was still N/A, but i would buy them so i had them there and ready to go for when i go to turbo...tuning twice would suck though lol

well from a few hundred form a junkyard to like 1500$ or so for pro drift LSD's. What do you want to do with it? How much money you got?

I'm running on an open diff. I plan on upgrading after I get my ECU and new engine mounts. I don't do much racing from a stop. I prefer to race from a roll (60mph or so) so it isn't that big of a deal for me.

^^^why is that fanatic?? I kinda like doing the light thing, because you have a reaction time to. But roll starts are fun to. lol racing is fun in general.

IDK. I just prefer to do races from a roll. More of a comparison of the cars moreso than the driver. But I enjoy both.

what are you thinking about in terms of an LSD when you do get one nissan fanatic?

Prolly just a J30 or something.

I don't want to spend any more than $500 is it's on LSD. I don't plan to drift I just need something that can get me traction on the ground especially when I launch.

Get a VLSD from a j30, 240SX or 300ZX, some might need a little modding to fit.

yeah a VLSD (viscous LSD-it works because of the fluid in it) would be fine for you. probably about 200-300 from a junkyard. thats probably what im going to get except i plan on getting mine rebuilt just because thats how i am. you really do lose a lot compared to a real LSD, but unless you are doing hardcore technical drifting you should be fine. but if you do a lot of burnouts and drifting after about a year it will be like you have no LSD so at that point just get it overhauled. oh and if you search for threads on this you will find all the info you need such as which cars and which years you can take them from.

whew! That's a lot of stuff to do with that KA motor to get it to handle boost. I was also wondering how much does labor cost these days to install stuff like the turbo kit, LSD, MAFS, SAFC, engine internals, and some other things.

Who knows. Most people who are involved in stuff like this are DIY'ers. Check on www.phatka-t.com and ask Ivan. He installs most of this stuff on a daily basis so he would know. Most of it is pretty easy stuff. You should look into how to do this stuff to save some money.

buy the tools which is labor cost, and do it yourself for the same price and walk out with a free set of tools ;)

Yea I was thinking about doing it myself, but the thing is I don't know how and I would like to learn, but I don't want to mess anything up and I want the job done right the first time. And another question, what kind of gas would I have to pump after I go turbo? Are there that much difference between different octane levels? This really bothers me because the price of gas is really skyrocketing right now.

If you don't want to spend alot on gas, don't get a turbo. And before everyone says he can stay out of the boost and save gas, he doesn't need a turbo to stay under 3000 RPM. You'll need at least 89 if not 91 once you go turbo.

It's ok I'm still willing to put in the money for gas I was just asking if I would have to put higher octane in. Would a KA-T with rebuilt motor running 8lbs or boost be able to beat a Integra LS(non-vtec) Turbo with the same mods from a roll(40mph and 60mph) and a stop?

well with the same mods it would really be in favor of the 240 because 2.4L vs. 1.8L but it would mainly come down to driver skill.

you'd probably kill the teg, but there are many aspects to look at (engine and driver wise), dont turbo your car just so you can beat that other guy you dont like....

Oh yea I don't plan to race one of those. Those are actually just my options of getting and I was wondering which one would be quicker. I'm not too picky about whether it is a Nissan or Honda or any other kind. In the beginning I wanted a '98-99 Subaru Impreza 2.5RS Coupe, but those are so hard to find these days so I gave up on that. I just now favor the 240SX because they aren't very popular around where I live (Arlington, TX) and they are RWD with nice displacement and I like the Silvia look. Most things I see around here are Hondas and V8s. I just want to be able to take the V8s. Doesn't the 240SX come with LSD on
the LE models? I just want the 97-98 240SX now instead of the older models because I like their looks a lot better.

lol
