Engine Swap

[Mean S14]

Hey guys I have a ? for you all.... which SR, S13 or S14 is the best for a 97 240? S13 are cheaper but the S14 has a ball bearing turbo? Stupid question i know i just dumped a civic and got a 97 240 so iam looking for more power... the KA doesnt seem like a good platform to boost... any suggestions?

MMMMMMMM

-SR20DET
-20B twin turbo
-VG30DETT
-VH41DE
-VH45DE
-KA24DET(i.e do ya motor up, hey 300hp arn't bad)
-350 small block chev..
-22b motor(Subaru 22b motor)
-3.3 motor(Subaru SVX 3.3l motor just get the turbo convertion done)
-basically stick with what ya know, the SR20DET or turbo your KA24, or throw it out the window and make something up that no one else has!!!!!

why do yo say that its not a good engine to turbo charge? &nbsp;i thought the same thing for a long time but it turns out that is not true at all. &nbsp;if you look at some old posts, then you can find instances of battles of the turbo KA vs. the SR swap. &nbsp;ill try and sum it up. &nbsp;the KA is a strong engine, and its almost entirely forged (except the pistons). &nbsp;its set up like a turbo engine, just with out a turbo. &nbsp;yeah, wierd, huh? &nbsp;with a nice 3-4k turbo set up, you can be at 7 psi of boost and making around 250 hp. &nbsp;not to shabby, but the big advantage of the KA is in its extra .4 L's of displacement. &nbsp;that equals quite a torque advantage. &nbsp;well, the SR swap has its strengths too, but its got its weaknesses. &nbsp;the problem with it is the initial cost. &nbsp;4-5k to get it installed. &nbsp;then, you have about 205 hp, but you have a factory turbo charged engine. &nbsp;now, you can go mod crazy, but dont break anything, it'll be a &nbsp;month or two before you can get parts from japan if you break something. &nbsp;so, i think the sr swap route would be a tad bit on the expensive side, while i think i can find something pretty cheap when i figure out a way to do my turbo kit. &nbsp;good luck man... &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/notify.gif" border="0" valign="absmiddle" alt=':notify:'>

also, doesn't the sr20 swap provide you with near perfect weight distro as well???

[rubbersidedown]

240 already has near perfect weight distribution.

any who, its whatever you really want to aim for.. I think in the long run to get a 10 second car with a KA motor... your going to spend more money on the ka than you would on the SR. The SR seems better for getting low times. Ive yet seen a 7second KA... If you just want to strap only around 200-300 hp I would go with the KA. If you want more than that I would go with the SR.

[Kitahara]

OT Reply: SR20 gives you NEAR perfect, yes. &nbsp;But the KA really isn't that far off, it is heavier but not enough to necesitate head scratching. &nbsp;After all, if the KA resulted in too heavy a front end to benefit from good weight balance performance, Nissan would have decided on a different stock motor. &nbsp;A lot of evidence points to the fact that a slightly heavier nose is better for track performance.

Now on topic: &nbsp;Doesn't look like you're intending on pushing too much power if you're considering the stock set up of the SR. &nbsp;In this case, stick with the KA, you'll be happier. &nbsp;The KA is a more impressionable engine in street situations (lower revs, little more torque) &nbsp;You can get a nice T3/T04e set up and do great. &nbsp;If you want to turn it into a monster someday with a more progressive higher revving power curve, you can: forged lower cr pistons, balancing, reworked cams, porting, etc. &nbsp;hell, If you're gonna go nuts, you can even enlarge the valves to make the engine behave even more like the SR, and have a serious serious turbo spec motor.

What the hell? &nbsp;Does nobody read either a) The hundreds of posts about this, or b) the only SCC with more than 2 240sx's in it? &nbsp;
How can people think that the SR motor is light? &nbsp;They put so much metal into that block to keep it together under boost. &nbsp;It is aluminum ALLOY, alloy having a high content of other HEAVY metals. &nbsp;Then they pack a LOT of that crap all around.
SCC *did* weigh each engine and transmission. &nbsp;The "Heavy iron block truck engine" weighs 493 pounds with tranny, and the "light, godly, perfect weight distribution" weighs 490 pounds with tranny.
Gee. &nbsp;I'd rather loose .4L displacement and a tough as nails IRON BLOCK for 3 pounds.
