240sx model questions. i need to be educated please inform me : )240sx

[bradenman1]

i need to know what year model 240sx is a s13 and which is a s14 and so on. I have just recently acquired a very distinct taste for the 240s and would like to do a sr20det or a rb..det swap in the next year or so. Can any one tell me what years are direct bolt ups or bolt on with slight modification with the SR / RB?

And also what kind of wiring and things are needed in a swap of this kind? I asume the ECU and wiring harness from the previous vehicle and the engine and trans (given), but is there any other necessary parts that need to be bought to do this swap successfully?

these answers are aaaallll over the stickies on this board.you can use the search button at the top of the page to find alot of answersthis will helphttp://forums.nicoclub.com/zer...stingand this too zerothread/301904as for the motor swaps there are right ups on herethe 240 came with the sr20 and ca18 in japan so the engines are easier to put in.the rb series came in the skyline and is a straight six so its bigger then the inline 4 sr and KAsome people have had to modify their engine bay to fit it and others have stated they didn't have to.

my friend has a vert with an rb20 and he said he had to put a dent in the firewall so the starter would fit.

I'll answer your first question and THEN give you a very valuable tool. Welcome to NICO btw

89-93 240sx = S1395-97(8?) 240sx = S14

And now...

Search is your friend. Go meet it.

well if you dont know anything about swaping in the 240sx just search if you dont know anything about swaping engine then dont bother swaping the rb. because it will require more work but if you have money then no problem my advice do the sr its a direct drop into the s13 or s14 with no mod to the car but only thing is wiring which is all over this forms just search but the easiest out of the 2 motors is just turbo the ka that you have on your 240 and welcome to nico.

Thanks a lot : ) the s13 has a more pointed front end doesn't it? or is there seperate body styles still considered an s13 in that year range?

iv never done an engine swap but i have replaced engines and trans. twice in other vehicles so i have at least some basic knowledge of how it goes in. I heard that the SR swap was alot cheaper and has more power than just throwing a turbo on the stock KA24

lolz ur not gonna fit an rb unless you wanna redoo your engine bay. But an sr20 will fit right in there with practically no mods.

s13 89-94s14 95-98

personally Id just rebuild the ka24de thats already in the car and add a nice t3-14 turbo. And if you really wanna do the swap then just go with the sr20 cause its alot less trouble then an rb.

Oh and the ka24det is just as powerful as the sr20. Its just that if you wanna get like 400hp out of the ka then you'll have to do a rebuild. For an Sr you just gotta add some extra parts like a bigger turbo and new cams and injectors.

That is also another option im considering... would it be cheaper to just rebuild and possably bore out and ad cams, rods, turbo etc. to the ka and still get alot of power for a reasonable sum? Iv heard people called the ka torque monsters lol i have a ka in my little Altima its got some pep for a little 4 banger

Hahaha Wc is right. There are stickies that explain this kinda thing. But thats alright cause u didn't know lolz.

Yea the Ka has a larger torque output generally because of the block. A Ka has a cast iron while the Sr is aluminium. So just because of the density of the metals the Ka will be the one thats more umm... Toughly built. But all in all its basically the same engine with simple differences. Such as the stock compression for an Sr is lower due to the turbocharger. So if you end up just modding the Ka then your gonna have to bore out the cylinders so the gaskets dont blow every time you get to like 13 psi. You'll also have to get new pistons and rods to fit the larger cylinders.

So you can get an Sr and save all the modding troubles. Or you can keep the Ka and mod it. It'll cost more to mod the Ka but you can set your engine miles back to zero.

If you have questions about Ka-t or the Sr20 scroll down to the site links and check there.

Good luck dude
