SR vs KA

[InKonCysTanT]

I know this gets redundant and I am sorry for it, but i gotta ask, since there is about 900 pages on this forum, and i dont wana go through them all. Basically, I have a 91' 240sx that some ####### put a KA24E engine in <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>...
I thinking engine swap, but do i do the SR or the KA?
Will the SR have the same torque range?
Becuase thats what i like about this car.

I am wondering, keep the KA and turbo it?
or get the SR?
I like Torque <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> (chevy owner)
hehe
Any input would be great.
Oh yah, and which would be cheaper in the long run

[BadMoJo]

Well, i would say build up a KA24DE and turbo it. But if you want more input try the search button at the top of the page. You will find many long topics about this.

[BboyOxygen]

I'm going to keep my DOHC ka and rebuild it with new rods and pistons.. Then turbo it. &nbsp;The biggest reason I'm doing this is because I live in Smog land california and I wouldnt be able to get a SR anyway and pass emissions.. But I do think that the KA is better for a build up and easier to find parts for.

They'll both most likely end up to be around the same, depending on how and where you get your parts from.

I'd say go with the KA.

[Ni5mo180SX]

YES! another KA vs. SR thread. lol

[whateverjames]

that's what's great about the search function, is you don't have to go through 900 pages.
if i were you'd i'd get the SR....if you will even go through with it and have the money...muahahahaha

[twin turbo]

yea, but you cant get new and updated info from old threads. granted is pretty much all covered in past threads but its no fun with no active threads

[drift freaq]

here we go again , let me see once a week? Or is it twice a week??#### lets beat a dead horse right into the ground. maybe he will rest in peace :biggrin: NA never happen. some newbie will come and ask the question again . yes the world goes round and round like a KA VS SR thread hahahhahahaha.
lets throw some logs on the fire.

go with the SR hahahahahaha (everyone knows this response is full of %^&amp;* me being the big low mileage KA prononent)

Seriously though. figure out how much you want to spend if you like revs more than torque and go from there . Nobody could make my decision for me. I had to make it myself. #### before I got the Turbo bug I was headed down the Normally aspirated road then I woke up and realized I could get exactly what I was looking for at 7-10 Lbs of boost. I was hooked .
SR's are cool , KA's are cool, CA18DET's are way cool (had to throw that into the mix folks :biggrin: ca18guy you reading this?)
Its all what you want to do and how you want to go .
this probably doesn't help you much but it is true :briggrin:

[dsjunkie]

keep the ka!!!! &nbsp;it has loads of torque waiting to be unleashed by a big fat turbo.....no really go w/ the ka cause it's got a bigger stroke than the sr and the stock internals will hold up a lot more than the sr...in other words you save $$$$ and quite a bit too.....well thats my 5 cents.....later

[oberkill]

The problem is he cant just keep the KA, it is a SOHC engine in a car that should have a DOHC! If you can find a good DOHC and prep it for the turbo before installing it that may be the way to go. I prefer the SR but have nothing against the KA's. Look around and see what each is going to cost, you are going to have to buy an engine no matter what, unless you want to turbo the SOHC. My vote would be SR in your case unless you came across a good lower milage DOHC KA for a decent price!

Have fun!
Alan

[ca18guy]

I agree with Oberkill that the SR is the way to go in this case. He needs a new engine so why not get a SR for cheap ($2500) instead of buying a KA ($800) then a turbo kit ($3600) with comes out to $4400, notice that that is nearly double the SR for that much you could buy alot of upgrades for the SR. Unlike someone said earlier the KA does'nt have stronger internals, they both have similar breaking points and the SR's internals can be upgraded using 300ZX pistons which are sometimes cheaper. Thats my opinion (of course I would get a CA18DET but i'm wierd)

[boosteds14]

again, it really depends on what your budget is and how much you are willing to spend to get what you really want.

maybe it is just me but i rode in a 240sx with an sr and then i compare it to my ka turbo and i believe i made the right decision. its just my opinion so dont critisize me,

I'm not gonna get into the whole which is cheaper (since no one every figures out that they don't need to buy a brand spanking new turbo kit anyways, as if the SR came with a T04e and 550cc injectors... riiiiiight).
I thought 300zx pistons were overbore for both the KA and SR??? &nbsp;Actually, I thought the KA and SR both had an 89mm bore, with the KA getting extra displacement through its longer stroke....

[oberkill]

SR has 86mm bore the 300zx bore is 87mm. It is a very easy upgrade for the SR to use the 300zx pistons but you usually end up buying 6!!! LOL You can get them in sets of 4 from JWT.

Hey, it's been some two weeks since one of these threads, let it slide <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'>

You mention you like torque, KA is torquey, use it. Contrary to what everybody here is saying, you CAN turbocharge a SOHC KA. THere are kits available. You could if you so dared build your own turbo as well for quite a bit cheaper than most kits (if you're smart like that).

[240meowth]

NOOO not KA or SR, CA man CA!!!

[wherezmytofu]

fuck sr...fuck ka.......and fuck ca!......its all about the VRH!

If he had the money for an indy car engine I think he'd probably just buy two cars and see which he liked better <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

[InKonCysTanT]

LOL
Ok, so I am GOING to rip out that KA24E engine.
But, so many mixed thoughts here.
Built KA24DE engine with turbo kit, or SR swap.

Dont wana to spend the money and time building an engine, i will probably go SR swap, but some people have been mentioning weak pistons and whatnot
While I have that SR engine out when i buy it, what things should i do to it while it is on the hoist?

Also, I read that S14 egnines are 250HP...
can i put that into my s13?
or is it too complicated?

And what pistons would i get? (do i need connecting rods or are those ok?)


-Eric

[InKonCysTanT]

I am just hoping, if i later decied to put a 2.0bar turbo on that engine, that it wil handle it.
=)
I need to rape my freind 318Ti with a euro m3 engine in it <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>

[misnomer]

KAs have the weaker pistons. Dunno for sure where the SR stands in relation. It's the s15 SR engine that outputs 250 hp. The s14 is 220, and the s13 is 205.

[InKonCysTanT]

ah
yes, can you put either of those engines in a s13 without trouble?

[sykikchimp]

the problem w/ the 250 hp SR is the price. &nbsp;Instead of the nice 2500 for the s13 redtop. &nbsp;The S15 sr is about $5000

[DuffMan]

Only the &nbsp;s15 has 250hp, and thats just because they upped the boost to 10psi.

When you say 2 bar do you mean actually 2 bar or 1 bar. Because I've seen some people measure boost as the total manifold pressure, which would make 1 bar into 2 bar.

The SR can take 1 bar without doing anything besides the basic fuel pump, intercooler and boost controller upgrades. This is good for about 250rwhp, depending on what mods you have. Some people have pushed it a little more, but for the most part to get beyond that point, you're going to need new injectors, bigger turbo, upgrades in fuel management, and forged internals would be best.

But if you really like torque, a built KA would be the way to go. It will probably cost as much as an equal performing SR swap.

Ok, so i want to know, if i get an s13 SR20DET engine, becuase so far it just seems easier to put in an engnie that is meant to be turbo charged and already has everything in it for 2500$ with tranny, as opposed to beuilding an engine that is not meant to be turbo charged.
Now.
I get an s13 SR20DET.
What (while i have the engine out)
should i consider upgrading, if i wana put a bigger turbo on the car? (can u say 21PSI?) hehe.
I am looking to put somewhere between 250-300 HP to the ground.
Let me know

[Nismos14]

maybe u could consider rebuilding he ka24e they have cheaper kits for this engine and a rebuild with turbo kit would net u less cost and woult work wonderfully

No offense, i'm very much infactuatated by the KA24E but in his case I think a SR is the best engine for him.

non taken, and i dont really think he can go wrong either way..... just my 2 bread crumbs

[MyFirst240SX]

Hey duffman the S15 Sr's have a different turbo and bigger injectors than the S13

[mbmbmb23]

Hey inkoncystant , &nbsp;why don't you try and goto a 240SX meet....and get a ride in a KA and a SR....then judge for yourself. &nbsp;Where do you live? &nbsp;If you live in a bigger city, there could be at least one of each in your area.

just a thought,

M

Well if you realy wanted something really sick, doesnt nissan make a 4.5L V8? They put it in the infinity G45. Build a twin turbo settup and you would be set. HEHE

That would be the shit!!!
