KA-T... newb alert...

[S14Kyle]

I was doing a little Microsoft Excel action to see which was cheaper, KA-T or SR swap... The SR swap was basically just the front clip for $2.5-3k, while the KA-T with F-MAX turbo kit (the lowest price turbo kit I have found in my countless days of searching for cheaper and more complete) plus forged rods and pistons comes to about $5k...
The SR swap sort of came out on top. I am no where near mechanically inclined and probably missed a LOT of things on the turbo kit, but with the front clip to the SR, it's complete in its self.

The reason I'm posting this is because I was searching through the 240SX forum and noted a KA-T thread talking about why turbo kits are so expensive, because everything is custom and they need a profit.
The reason I wanna go with the KA-T instead of the SR is because of the following reasons.
1.) I love my engine S/He is very good to me and I have become quite attached to him/her.
2.) The SR is so cliché now... It seems like everyone and their mom wants one.
3.) I don't drift... (THE MAIN REASON) I bought my 240 originally because I love Nissans and can't afford a 300ZX in good condition.
4.) My main goal with my car is to show all the domestic cars who's boss (obviously Nissan) and couldn't do that (or wouldn't dream of) with a front wheel drive car, and can pretty much only do that in a straight line. Don't get me wrong. I LOVE going around curves fast, which is why I am also upgrading my suspension, but if you want to beat the domestics that are HARDCORE anti-import, you need to play their game.

As much as I love the SR, it just isn't in my game plan.

What is everything needed in KA-T setup? Would I absolutely need to put forged pistons and rod in the engine? Also, since an engine needs to be balanced would it be with the new pistons and rods? I heard that the crank is already, which I would also like to know is true or false... Turboing the KA seems so complex, and I have read no difinitive answer stating exactly what I need for long engine life and decent power @ about 12psi...
Here's what I know I need for the KA-T:
-Bigger injectors so it doesn't run lean
-turbo (obviously)
-turbo manifold
-turbo downpipe
-wastegate
-intercooler
-intercooler piping
-intake manifold
-bypass valve (which i am not clear on what it is exactly)
-upgraded ecu/software. I'm not quite sure how to get ahold of new software...
Is there anything else u'd need for a KA-T? I'm not sure if you need forged pistons and rods, which boggles the hell out of me.

I'm a little hesitant to post this, because I'm almost sure everyone's gonna hate me that knows the answer to this... Plus it's probably pretty obvious...

Any and ALL responses to this post will be MUCH appreciated, even if they're calling me a dickhead for asking this question. Please help!

NOTE: You will never see any stickers, neons, or poor-taste body mods on my car that don't do anything to performance. I am not a ricer and never will be, I just am inexperienced when it comes to REAL engines because I'm in the middle of prodomestic-ville.

Oil lines that go to the turbine and back.Need to modify your oil pan for those.

Boost controller
Turbo timer
upgraded fuel pump
fuel pressure regulator
downpipe
oil cooler and oil catch tank for extra insurance and performance

Thats what I can think of at the moment

No problem.I've been doing research on the same thing too If you wanna run higher boost forged pistons and connecting rods are a must!!!
I plan on turbocharging my SOHC KA someday in the future but first I need to replace my,uuhhhh,broken tension rod,bent tie rod,and vertical link(I think that's what its called..)and the tire



For your ECU woes try Jim wolf technologies or http://www.sdsefi.com/

This may be of some help too---->http://www.240sx.org/links/installs/

What do you mean by high boost? 15psi? 20psi? I'll probably only run it at 12... 15max...

I CANNOT BELIEVE YOU ARE WASTING MY TIME! GO LOOK IN THE FAQ BEFORE POSTING THIS SHIT

J/K who am I??

Anyways... my fiance wants to supercharge my car... or put an engine from a Q45 in my 240. He wants to do something different because like you said, everyone wants an SR20.

Has anyone heard of doing this, or knows of anyone that has done/tired it? Of course I wont let him touch it, at least not now (it only has 60k miles on it)

lol...
Anyway, I have heard of someone WANTING to do it, but everyone discouraged him a lot... I don't think it ever went through. I'm talking about the VK45DE swap btw. Since they can fit RB26DETT's in there maybe with *enough* love you could slide one in... And cutting out the firewalls, lol. I'd be interested if you actually got a VK45DE in there though. Don't supercharge! You lose 50% of the gained hp in friction and when you aren't getting boost you're losing horsepower too! Turbo!

[dayna240sx]

The supercharger would have an RPM control clutch

[SR20DETpower]

ok heres how you can do a KAT setup for just over a grand with some good shopping.

I've seen brand new Garret T3/T4's for 450 before but now they are 550.....cheapturbo.com.......

U-H manifold

TIAL external wastegate(screw internal wastegates, and I consider TIAL to be the best..... get it not some cheap shit this part can make or break your engine.)

BOV again I like the TIAL one but that is expensive..... for a cheaper setup you would need something like an Apexi Twin Chamber..... but splurge a lil bit.

Run it without an intercooler.....


get a manual boost controller

get a wastegate spring for now that is really low, say like 6psi max boost allowed even if it spikes.

I always thought you would need some upgraded injectors etc..... but I just saw a guy running stock MAF, stock fuel injectors, and stock ECU putting down 5.8psi I believe and making 225rwhp. Thats a hell of a lot more then a stock SR....... and about 3 times as cheap. And if you want to drag race a KA will stomp some shit.

so lets say you want 225rwhp for right now..... thats a good improvement and can be obtained for just over a grand with a couple decent parts. As you save more money get some stuff in stages... after that the next thing I would buy is an intercooler, I like spearcos.......they are more effecient so you can run a smaller one and its rated for more HP then bigger ones of Greddy type etc..... smaller intercooler=less of a drop in boost, power, and better throttle response.
After that I would get some BIG injectors and some sorta ECU. why buy yourself some 450 injectors say then want 550's then 720's later on.... just get some 550's or 720's hehe. You'll also want a bigger fuel pump and fuel filter at this point. Then I would get myself a nice electronic boost controller..... for a KA-T setup I think that the Greddy Profec Spec B is great becaause its a self learning boost controller that is easier to setup, especially on an engine that has been converted to turbo. At this point you might want to crank her up to 12psi or so getting around 300rwhp+. Its a great engine..... I've heard of some guys that run 450rwhp on a stock internal KA-T....someone said it was a secret as to how it was done.....

But I would upgrade my pistons to some forged ones and better connecting rods abover 350rwhp.... just for durability and security reasons........

with that you have a bullet proof system that as long as its tuned you could raise the boost to probably 30psi if your turbo can handle it, also one more thing....... if you have to buy a turbo to make your setup go... don't go small go big.... get atleast a T3/t4 or a straight T4.... just keep your boost down until you get everything. No sense in buying a T3 or a T25 to just buy another turbo later on..........



thats your basic KA-T setup plan..... if you need to know more about certain areas email me, pm me whatever........

you guys type too. much heheh here let me break it down to more simple terms

go to www.realnissan.com

they will have the cheapest parts for your car possible. you can save over 1000 in parts. and trust them, theyre not a shop, they are a bunch of enthusist that wants to help other nissan guys out. here is what you need

the basics

1: turbo
2: intercooler piping
3: intake pipe
4: waste gate
5: blow off valve
6: intercooler
7: downpipe
8: downpipe flanges

now for the fuel

1:either a vortec or bell fmu
2: apexi super afc

there is a problem with a open atmosphere blow off valve. for our cars, if you let off the gas on boost, your car will stall becaus eit will run soo rich. the apexi super afc will cut off fuel and will prevent stalling

and you need to run a intercooler no matter what becasue even though you are drawing in cold air, the air heats up alot from the turbine and compressor becuase it has to go thru hot exhuast gaes. after a while your head gasket and your piston rings will start to feel it.

for a spartan kit like i mentioned will cost just alittle over 3 grand, and you will be pushing around 200whp. you do'nt need internals on the KA unless you want to go crazy, and the stock fuel system is good for up to around 7 psi. yes i know i'll be runnign 8 but i'm goin to make my car run rich. with the piggy back system.

I read on multiple websites that with stock internals, it will run 6psi and up... Not that big a difference, just wanted to say that. I think bigger injectors are a must ANYWAY.

Also, with those HUGE injectors around 700cc's or even 500cc's, does the car GUZZLE gas? What would expected gas mileage be? (I can't afford to be getting 93 octane gas every 3 days if I just bought new turbo stuff).

wtf...you'll notice even SR20DETPower does that...its only for questions that have been assked 11ty billion times...

This IS a VERY legit question, but since KA-Ts are not my forte, I have to back off
