I lived pretty much on 240sx.org for the past year and have done a lot of research on the SR,CA, and KA engines. With a standard turbo kit on a KA it will make more horse power than a S13 or S14 SR20DET, and a good bit more torqe. But it isn't as reliable. But then again comes in the old addage, "there is no replacement for displacement." The 2.4 is a better choice if it is built for forced induction over the 2.0 and 1.8.

The RB26DETT is a whole different story. I would like to have that engine in either one, 240 or rx7. That engine rocks but cost an arm and leg to get and the install would be as much as the engine is to buy. But it would be awsome.

Are you crazy? You even said yourself the KA isn't as relaible. Personally, I want reliable speed over more speed. The $$$ saved by a SR swap over a built KA would make it a much better all around car. Plus, who wants a turbo truck engine in their car The internals of the SR are mad strong, and that is what sells it for me. If you want to be different, or have $$$ to burn on a fully built bottom end, sure go for the KA.

stock for stock the KA-t has more hp than the SR, however to get the KA to the level where it can take as much boost as the SR can stock it takes $$$ ... lots of $$$... for example, on my SR with an upgraded turbo, MAF, ECU and injectors (that includes my D/P, T/P, and exhaust, too) I will be able to easily push over 300hp at the wheels.. to do the same with the KA would require a complete engine rebuild... get the picture?

HALO

This is simply my opinion but, a turbo KA is the way to go. $3995 for an NSport stage one turbo kit where you should make close to 240 rwhp.

(This is info from a very reputable shop that does the SR and other 240 swaps. )
$2500 plus shipping for a red top SR20. which makes a claimed 205 hp. installed is $4080. An S15 will cost you around $4500 dollars or $6080 installed.

The shops stage three engine build and upgrade.
Output at this level: 240HP (flywheel) Maximum output : 240HP to 300+HP (depends on other mods) the price is an estimated $9000.

Now NSport's stage three kit cost $7049. But you have to do your own building, "and is good for nearly 300HP. "

So as you can see, each can be made to do the same things. It is just a matter of prefrence. The KA route would be about the same price as the built SR after getting a good builder to tear into it. Bottom line is 300 hp is gonna cost you. Wheter you want an SR or built KA-T.

My choice is to make a "Ghetto" turbo system. Everything you need other than the turbo manifold you can get from a junk yard. Turbo from the VG30DET, intercooler from various other models, and so on. Had a couple of guys go this route and come out at $1200 and made around 230hp. At 5 to 7 psi the KA will be good to go, depending on how good of a condition the KA is in. Of course get a leak down and compression test before trying to Turbo any non turbo model car.

This is just my opinion. Who's to say I am right? This is the biggest fued on the 240 site. And will continue to be.

heh... yeah, this is kind of a pointless arguement... it really comes down to if you have a good, low-mileage KA then a KA-t is probably going to be your best bet, however, if you're like me, and u have (had) an SOHC KA w/ a shitload of miles then the SR was actually the cheapest route for me... we'll just have to agree to disagree

HALO

You didn't say SOHC before. Screw that.

And to be honest, I would darn near kill for an SR equipped 240. I am just a poor SOB and hence the "Ghetto" turbo kit listed above. That is the only reason I was swayed to the KA-T side (the dark side of the force). $1200 for approximatly 230 hp. That is what sold me on the 240. But now I am the owner of a non running 1987 RX7 with only one door and no tail lights. But hey, it only cost a hundred dollars.

You know there is a company that puts out a turbo manifold for the SOHC. But I dont think I would go that route.


To heck with this. Lets talk about RX7's!

My best friend and roommate has a 1990 240SX hatch, and we will hopefully be droppin in a SR20DET black top and the 5 speed in before this time next year. Yes, the KA turbo kit would be ok, but not above the 5-7psi. The SR20DET can handle WAY more than that stock, and can be had for quite cheap ($3k for engine, turbo, tranny, ECU, harness, etc). I think a SR20DET FC is a bad idea, but a killer engine. One day, I will have a PS13 w/ a black top in her.

HALO

If your friend isn't already on the 240 boards here is the site for the new forum. http://www.nissaninfiniticlub.net/

240sx.org and the rest of the nissan/infinity crowd just started another site a few days ago. The 240 section is by far the best resorce on the web for a 240sx owner.

Who is he getting his black top from?
Unstable-hybrids is just over the road in FL. That is who I would go through. I

would love to have a 240. And I probally will. But right now we are gonna turn the POS RX I now own into a street terror. The basic mods with a little nitrous. Probally blow the darn thing up but I dont care. It will be fun.

FullRunOnevia

sorry... my car is an '89....

please dont kill me for mine

but i like 240s.....

HALO

Yeah me too. But I can't wait until I get my ReX on the road. I have to make my cavalier z24 pretty to get a title loan so I can get the RX "On the road again."

We could always discuss a 13b powered 240sx.



PS lets not get to in depth. I have been drinking and just don't think I can hold down a civilized conversation.

FullRunOnevia

13b powered 240?... now 'dems fightin' words...

jspecracer7

Rico, I am SO glad someone else on this forum understands the difference between a "silvia" and an S13. You definitely get a from the guys over in Japan

jspecracer7

What turbine will you be using. A T-04E turbine boosting 1.0 kilos will make 320 hp at the wheels with a 300zx air flow meter and 550cc injectors...plus ECU tuning, full exhaust and FMIC.

HALO

What about me? I know the difference between a 240 and a Silvia. Silvia's are only right hand drive.

But if I had an S14 and money, I would put a red top SR20 and an S15 bodykit with Silvia symbols on it. I still know the difference, thou.

jspecracer7

That's not what I meant. I see a bunch of uneducated posters here saying, " I have a friend of a friend of a friend that put a silvia engine in his 240SX. Wow, he's really fast."

In a previous post, I named the types of engine's that could have gone in the silvia. One of them is an N/A. A better sentence would have been, "I have a friend of a friend of a friend that put an SR20DET engine in his 240sx. Wow, he's really fast."

BIG difference. Also, there's a difference between S14/S15/Silvia/SR20DET/Blacktop/Redtop. I can at least say that I know the difference and use them properly.

HALO

Sounds like you been hanging out the smae places on the web that I have.

not everyone can be experts on every car. Look at me. I dont know much about RX-7's. But I am here to learn. hopefully they we learn as well.

Give ma a month or two and I will sound like I know what I am talking about on these cars. LOL

Oh well, I am drunk and going to bed. Good night!

Ni5mo180SX

The KA-T has been shown to handle 350hp easy on stock internals.

jspecracer7

Nope. I get to handle these engine on a weekly basis. Some of my best buds have SR20's. I always give them crap about their car, and they do the same. I KNOW my SR20DET crap. I ask questions about their car just as much as they ask questions about my FD. Informed...absolutely.

Jerk_Racer

You think you know differences between the JDM and USM (it's not D omestic market really) S13 frame rails? Is there a difference? You tell me.
jspecracer7: ask Hugh this one. He might know it. He's owned both after all. It it really trivial though.
