whats needed

[scott]

i have been searching for a while now and it is starting to sound complicated. i have a 93 240sx and thought about turboing it. i'm not sure of EVERYTHING needed for a complete setup for 350hp~ to the wheels. everyone talking about tuneing and wiring and safc, e-manage, mafs, jwt ecu, detonation, etc. etc. etc. etc. is really starting to confuse me. i have a couple of import performance shops within an 1 1/2 drive of here. but i would like to do as much work myself to keep the price low. its starting to give me a headache already and i havent even bought anything yet. i need some help deciding what to get for a complete kit and how it works.

Not wanting to sound like a prick, but it sounds like you've got a lot to learn and we cant teach you everything you need to know in this thread. Sounds like you need to do a LOT of research. Use the search button and read through all the posts in this forum and you'll pick up 99% of what you need to know.

Here's a link to how turbos work:http://auto.howstuffworks.com/turbo.htm

tuning = adjusting the amount of fuel that gets squirted into the engine and when, adjusting the ignition timing how much and when

S-AFC - Apexi's little piggyback for tuning Air/Fuel

E-Manage - Greddy's more advanced piggyback for tuning air/fuel and also timing if im not mistaken

JWT ECU - Send your ECU off with your car's specs and they'll change the ROM info to work with your injectors/fuel pressure, MAFS

Detonation - What happens when an engine isnt tuned right. Nothing more than an annoying sound from the engine...letting you know its on the virge of blowing up.

you can save a lot of money by doing stuff yourself. i did everything myself for my turbo including IC piping, downpipe, manifold, flanges, etc and it cost me a total of $1400. now if you are wanting 350hp then you are going to have to do some internal work on the motor ie pistons etc. i left my motor stock and im probably pushing around 250rwhp.

Dude, Im starting my ka-t project, now after at least 5 months of research. What you have to do now is always scowre all the ka forums online learning about peoples setups and what works and what works best. You asking broad questions. I garentee you everything you want to know about ka-t's can be found on theese forums just look at past threads. Some good sites are jgstools.com, ka24development.com read those sites top to bottom.

i have been reading post and thats how i heard of all of this stuff. i'm just a little confused when people start talking about hacking a maf, or doing a lot of tuning to their e-manage. i'm guessing they have to do all of that tuning because it was set up for an s14 instead of an s13??? how exactly do you TUNE your settings. do you have to take it somewhere or can you do it yourself with certain electronic tools(s-afc, etc.)if so, is it difficult to understand how to adjust one of these things to make it run right.

i know you can save alot of money by doing things yourself, but i dont have the tools to bend pipeing for the fmic, or the knowledge on how to make a exhaust manifold from nothing but pipe and flanges.

I think what you are not understanding is that the guys running piggy-backs and hacked MAF's are doing so to run larger injectors. Turbo's add more air so more fuel is needed. But the stock fuel system can only provide enough fuel for about 4 psi of boost before it becomes dangerously lean. But you can't just drop in larger injectors and call it a day. You have to fool the ECU into thinking less air is going into the motor so that it shortens the injector pulsewidth.

My suggestion is to pick up a copy of Maximum Boost by Corky Bell. Read it a few times until you have a decent understanding of it. Turbocharging a car is not rocket science, but you do need to know enough so that you don't blow-up your motor in the process. Once you are familiar with it or if you run into things you do not understand, you can ask more specific questions. I doubt anyone here will want to try to explain what it takes Corky Bell 200+ pages to explain. in fact, I doubt that there are any websites that will be as comprehensive. We've probably discussed most of the stuff here, but it will be spread out over many, many threads. Once you have a grasp of the basics, you'll be in a position to better understand the discussions we have here and ask more specific questions.

to be honest, maximum boost is good reading but if you just scour the forums online you will start to understand everything you need to...but reading always helps, I read everything I can get my hands on...

[daniel240]

yea a few months ago i didnt know sh*t about turbos and now i just finished installing a full custom turbo setup myself on my car. i learned everything by reading the forums and asking ?'s.

[scott]

i have done some reasearch and found a list of parts needed for a turbo kit in the forums. this is what i have found mainly on ebay and a couple other sites. tell me if these figures sound about right and what other ideas you guys have for the computer side of the system. also what trims and a/r levels are good for the ka24de if i want 300-350hp. i'm planning on getting forged pistons and rods for the boost and also i have been thinking of adding nitrous later. what might i have to do to run the 300-350hp plus nitrous?

[SloS13]

no offense, but isnt that basically the same question you asked at the beginning of the thread?

[hannibal]

A lot of guys on here have websites about their KA-Ts. Check out some of these to get an idea of what parts are involved in a 300whp setup. Also take a look at some of the kits available to see whats included.http://www.nsport.comhttp://www.greddy. ... eering.com

Basically you need to figure out how much air it takes to reach you power goals, then how much fuel that amount of air needs to maintain good A/F ratios, and finally the best way to control that fuel. Now you can choose a turbo and fuel system (injectors, pump, etc) to meet these requirements.

There are literally dozens of different fuel management methods, from free (hacked MAF) to $200-300 (piggybacks - Emanage, S-AFC) to $500-600 (JWT ECU retune) to $2000 and up (standalones - Haltech, Motec, SDS).

Ive been reading on this forum for almost 2 years and I dont even have a 240sx yet. It takes some time to gather the necessary info. Good luck!

[scott]

you have been reading these forums THAT long and dont even have a 240 yet. did you own some other nissan car and wanted good info or something??

[hannibal]

You wanna turbo your 240sx and dont even know what detonation is??

Seriously though, I wasnt planning to wait this long to get my S14. But things happen, like totalling my old beater a month before I got a raise. I had some money saved up, not enough for the 240sx I wanted. So I bought an Escort, something to get me by while I'll continue to save money. Just paying my dues, I guess. By this summer, I plan to buy the S14 cash and spend the "payment" money on performance stuff. I dont like to owe people money!

I read a post by a guy who bought a 240 with a blown motor. While saving up money for the swap, he said he used to go out in the driveway and just sit in his non running car and imagine "what was soon to come". Good things come to those who wait...And for the record, there's no such thing as too much info!!

Got a riddle for ya too.Q: How much is a 99 Escort worth??

A: a 10-12psi KA24DET setup
