Engine Questions

[bladen]

Okay, my question is this,
i want to build a Fairly fast Engine,( 350-400 rwhp)
and i want to know, would the KA24DE be  a good engine to get this out of. would i be better off with a SR, i have looked into the SR and it seems it would be fairly easy to get that kind of power out of it, but i like how much torque the KA puts out, so im checking out the pro's and con's of each,
i want the car to have good acceleration, but im looking more at the TOP END aspect of it, but the thing is, money is a issue, so i guess my real question is wich would be cheaper ( and More reliable) to go with, a KA24DE+T or a SR, i dont want to have to wait for parts to be shipped to me for the SR, but it seems to be the way to go for Higher Horsepower, i dunno, i searched the system and couldnt find much on this, mostly it was people who just wanted info on the swap its self, i am just trying to Decide what i would like to do. and i cant decide because there are some aspects of it that i dont know. any help would be great

I'd recommend a KA with forged internals. You COULD do it on stock internals, but I wouldn't.

[XylathaneGTR]

Either engine is very good...The SR gives more hp stock, while the Ka gives a lot of torque.
A con of the sr, is most of your parts would have to be shipped from japan, and for someone on a budget, that can be a real bitch.
There is a wide avalibility for each engine, so the choice is yours.
Jun has a 700hp s13 with an sr20 <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=''>

Either engine is pretty much just a capable - the SR has seen higher hp numbers than the KA, but the KA hasn't been a hot engine nearly as long. &nbsp;If you're looking at the top end, though, DEFINATELY go with the SR. &nbsp;As all of the 1500 other threads that have been about this have said, they're both great - get the KA if you want a strong low end, the SR if you want a strong high end.

[AceInHole]

well.... how many SR owners in the US have their cars above 500hp?? &nbsp;There's been a couple KA's up around the 500 range... and one in particular that did 10 second 1/4 miles with a full interior and a decent sound system. &nbsp;I've never really heard of SR's with more than 350 or so HP.... at least in the US, on the streets...

[crazycuban]

No doubt, but on the other hand you can get off the shelf parts for pretty much any power level for the SR...sleeves, everything in the head, everything in the bottom end...stroker kits...yeah, I'm sure you know. &nbsp;People haven't been tuning the RWD SR in the states long enough to have power levels that high.

Supposedly Non Fujita's S14 has a little over 400.

im with ace on this one, ka is the motor u should go with

well... how long have people been tuning KA's??? &nbsp;You'd think there'd be more high powered SR's out there, but there aren't. &nbsp;All this time, people have been saying you can get more out of an SR, but have nothing to show for it, that's all. &nbsp;Untill someone with an SR can match what Duy's done... I pretty much rest my case. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=''>

[boosteds14]

ya, show me dyno sheets of sr's going above 450rwhp. atleast 2. because i can back my staement of 2 ka's having 400+rwhp

[240racr]

Just something to think about:

I don't know how many of you are into road racing, but the s14 has a 55f/45r weight bias. If you go with the SR you will have a better weight bias. KA's have a Iron block while SR's are Aluminum.

[AceInHole]

if weight is a primary concern... why not stick a tiny little CA18DET in there?? &nbsp;The weight difference between the KA and the SR isn't really what some people make it out to be.

[crazycuban]

...
This isn't about which engine each of us likes better...the point is the SR is definately capable of high power levels, and has been proven so (not in the states yet, but if they're making 800 and 900 hp SR's in Japan, its a matter of time before we catch up...and he said he wants a high revving engine. I like the SR better, but if someone said he wanted a torque monster, I'd tell em to get the KA. Of course, you could get a KA, change the power characteristics with better head internals, maybe even destroking it, but then whats the point?

The guy said he wanted 350-400 rwhp anyway. &nbsp;That has definately been done.

[thich]

a lot of what you guys are arguing is correct and true.. but you guys keep mentioning no one has any SRs over 500rwhp etc... you guys didn't look at crazycuban's post carefully or something? Most of the crazy tuning parts for the SR20 aren't readily available here! and it'd cost MORE to tune it at THIS stage in time than to tune the KA IMHO.
The lack of support for the SR20 rite now is the crippling factor to how much an individual can do to the engine.
As for the argument with the CA18... it's probably the best engine out of all three. It's handicap is the fact that it hasn't been in production for about 10 years and finding replacements isn't easy/cheap on the pockets.

as well... you guys mentioned Jun's SR20 and Non's SR20.. both are actually bored/stroked models of the engine, Jun's is a 2.2L I think and Non's is 2.1L. Non makes a stock output of 350hp to the crank.
----
I think this argument has been argued to death. If someone wants an engine, let them choose it... why do we have to dispute which engine is better, etc.??
and if they want high revving + lotsa torque, tell them to shove out 15kUSD and get the Tomei engine..... 380hp, 360lbs/tq... sounds good to me. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/hmmm.gif" border="0" valign="absmiddle" alt=':hmmm:'>

[DrDubbleB]

But if he wants a high revving engine, the CA18DET revs even higher than the SR, and it's cheaper, and it's an Iron block. &nbsp;It makes less HP stock though, but that can easily be fixed. &nbsp;Personally I am going with the SR, as I'm sure all of you know by now, I say it often enough! &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=''> &nbsp; But if it's all about high revs and power, the CA can deliver the goods.

Also, no, the weight difference between the SR and the KA is not enough to notice. &nbsp;One is aluminum, one is iron, true, but the SR is reinforced soo much to make it strong, that it makes the weight difference unnoticable, unless you are putting it in a stripped drag car.

These aren't the two most powerful SR's in Japan, they are show cars, not street racers. The engine in Non Fujita's car is actual a Tomei built race motor, which increased it to a 2.1L engine, dubbed an SR21DET. He does not have many performance mods though, just bragging rights on the engine. Even the turbo isn't upgraded highly, still comes in the T25 trim. So yeah, it's been bored to 2.1L, but would it make that much of a difference???

[thich]

you sure it's a T25? <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>
all I know is that it makes enough power to dwarf the S15's engine. At 2.1L I say it makes a bunch of difference when it comes to mods who has the more power and more torque (no replacement for displacement); at 2.2L, Tomei's engine rocks with massive amounts of torque that's readily available.

I also agree about how Non doesn't use his car. just bragging rights.. but what bragging rights they are!
$10kUSD for the 2.1L Tomei engine
$15kUSD for the 2.2L Tomei engine... what an investment <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

however, like you said.. if you want a NICER engine.. choose the CA18... much better output! 9,000redline..... iron block = crazy boost &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cool.gif" border="0" valign="absmiddle" alt=''>

[MyFirst240SX]

To build up whats the cheapest, how much ezer is KA Turbo parts than SR upgrades? who has experience?
