Ok, let's compare low end torque on the KA and SR

[kustom]

you know what's  funny? I started this post because i wanted to know if i'd feel a noticable torque drop when i swapped in the SR. So far only 3 people have actually addressed this....
I understand that some of you know a #### of a lot about these engines so why not enlighten us lowly folk by commenting on the actual question? Instead, it seems like every SR post turns into the same tired KA/SR/CA/RB debate. It seems like no-one really knows any of these answers so they just talk about what they do know....

I'm not trying to  be harsh, it just seems kind of pointless that everytime someone asks a real question you guys ignore it and head straight into this tired debate.

[240sxtreme]

anytime you ask people to talk about the difference between the SR and the KA this happens.....on any forum.

the answer to your question lies in those 2 dynos(dynoes??).  with a  lot less HP, the KA will give you a crapload more of torque.  So if thats what you want, and don't care that you don't have a shiny red valve cover, the KA is your engine.

whenever people talk  about SR's and KA's, they always bring up mass amounts of HP, like 400-up....I've yet to hear of any 400-up HP 240 SR20 or not, that is driven on the streets at that amount!!!  and if you're creating a track car, the KA will still do well.  Look at Duy's car, and another guy just in freshalloy.com posted a dyno of his 420hp KA running at 22psi.  they think he'll be able to get 30 more without raising the psi.  so you guys think the KA can't do it?  hmmm....maybe nobody's ever tried, cause the KA doesn't look pretty and isn't what's in Japan...

as far as the stangs and novas needing the lowend torque for their "massive wieght"....3300 is not "massive weight" to me.  in fact, if that's stock, I'm sure you could get it down close to 3k.  ours are 2700 guys, we're not civic hatchbacks here.  please get your facts straight.  The stangs and novas have a  lot of lowend torque, so they can spank cars like ours...with the SR20.  of course, when we get on road courses, things even out a bit.

WTF?<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'> Where in my post did I bash on the KA? I happen to like the KA. I simply stated facts. Whats with saying I can't drive? I didn't attack you. I drive very well in fact. I raced GT3 before I became a driftaholic. You people need to stop assuming that you know everything.

[drift freaq]

Ok, Socom fair game, &nbsp;My posts were more directed at your statements, which did come off very KA hating. I am sorry if it leaned towards a direct affront to you. It was meant to be about your statements. Yet your statements were worded in such a manner that it sounded like you where trashing the KA. I do not pretend to know everything.
If I did I would not exist on this planet i.e. by my philosphy we are on this planet to learn.
With that I apologize to you if it got personal . I also respect the fact that you have raced GT3.
Yet i will not back down on my statements about the SR20, CA18 and the KA they are based in fact. I also feel they did not come off as know it all. They were facts that i have collected. &nbsp;take care

[ca18guy]

To answer your question, no you won't feel like your missing anything during low RPM's. You'll still have more torque then you did with the stock KA. I rarely rev my engine over 3000, and my engine is a lowely 1.8 liter <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> Doe's anyone know what the red line is on the SR, cause my CA redlines at 7000 and i think the SR redlines higher, which would be contrary to what I have read in someone's post.

I like the sound of that but what's with all the people saying that the SR has no low end torque? I read several posts from people saying that they were disappointed with the SR....
I am pretty sure that the redline for the SR is 7500

[ca18guy]

People with KA turbo's do have more torque, due to the displacement. Some people like the feel of the torque, so to make them feel good they try to say that there &quot;choice&quot; in engine is the best cause they have this or that. When in reality, weather you have a KA-T, SR-T, CA-T, or a LT-1(v8) for all i care, you still come out better then stock.

[socom1]

The redline for a stock SR20DET is 7000rpm, the S-15's blacktop with VVT redlines a little higher at 7500rpm. The CA18DET stock revs out to a screaming 7900rpm!

A stock CA do's not rev to 7900 rpm's

[ca18guy]

here's a pic of my dash, hard to see but red line is 7000

[socom1]

Strange. That info came from the Nissan tech site.

[konkman]

You know, of course the higher cc motors are going to have higher hp, higher redline and lower torque. &nbsp;That goes without saying, but if just seems that most people who are blindly looking for more power (I'm not pointing fingers) most look to the red tops and the vvt black tops of the s15's. &nbsp;

What reasons do you guy's have for the swap (not a loaded question, just curious)?

[misnomer]

. . .I like your steering wheel. . .

[240sxtreme]

I've never heard anyone being disappointed with the lowend torque of the SR....just that they wish it had the torque of the KA....but then, we all wish we had a perfect motor. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

Also, I don't think that where your engine redlines really ought to matter when looking at one. the KA goes to 6800. I doubt any of these actually make power all the way to the redline. in it's stock form, I believe the KA loses power after 5600. so there's basically 1k left before redline doing nothing. someone please feel free to correct if I'm wrong here. with bolt ons and ecu, you should be able to raise that to at least 6-6200k.
I've never heard exactly where the SR stops producing power, but I'm sure it's not at 7...
and Konkman, that is what I've been trying to say...people really need to talk to people who drive KADET's and see dynos, not just listen to people who are biased towards the SR20.

I think if you wanted a quick 300hp, I think the KA would be more sufficient then the SR, cause even after the SR swap, you'd have to upgrade parts to raise it to 300. Not to mention afterwards, you'd still have an imported engine, so you can't take it to billy bob's mechanic shop down the street.
I mean, for the price of a swap, you can get the nsport kit, be at 240@wheels, and still take it to the mechanics.

but just so people don't think I don't like the SR20, I do..I really do, I just think that people are starting to become a little too biased towards the SR20, because that's what everyone else says. the first time I took my car out on the streets here in Portland, the first thing someone said to me is, you gonna put the SR20 into it?

also, one of my friends, during the first few weeks he knew me, started bashing on how he didn't like the KA....even though he knew nothing about it...why didn't he like it...things he's heard about them. &nbsp;after I took him for a ride with I/h/e, JWT ecu, cold air extension...he loved it.

[Drifting Ricer]

konkman I know you're not pointing fingers so you think I'm blindly looking for power? I'm a novice I'm open to suggestion and constructive criticism.

I do have reasons to want a SR

Seems cheaper.
Lighter then the KA hopefully make the car more auto X worthy.
That cool red or black top... LOL just kidding.
Higher REVS.
Call me dumb but I don't really dig the KA torguey nature. But that's just my preference not based on that it will be necessary better.

Still how much $$$ can I find a turbo worthy KA for? My engine right now has a 126,000 miles so I don't think it's ready for anything but the junkyard unless it's cheaper to rebuild.
One more question so if brake something on a SR I have to get it From Japan right?

Last thing I'm trying to steal any ones theard I just curious. I would like to get some help. I though I ask those question because they have not been ask before? Still planing to do sometime big with in a year and a half.

[socom1]

Many parts can be had off of the USDM SR20de engines......but not all.

[240sxtreme]

hey, do you guys know about the 240sx online resource we have? &nbsp;not start s***, just making sure &nbsp;we all know 240sx.org
okay, if you goto 240sx.org, check out the faq's, then SR20DET, it'll take you to heavythrottle.com.....but you're mostly interested in this page <a href="http://srswap.com/faq_partinter.htm" target='_blank'>http://srswap.com/faq_partinter.htm</a>

as you can see, you can interchange most parts. &nbsp;and there are more and more parts becoming stocked by your local performance shop (in my best commercial voice), but you'll still have to have a friend or yourself diagnose any trouble you might have with it. &nbsp; Not trying to scare anyone off, just make sure you're really ready to get into mechanics <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

[Archangel]

The reasons I've thought about getting an sr20:

My Ka has about 75k miles on it now.
I won't have money for a turbo or swap for a couple of years.
If I am correct (let me know if I'm wrong), most imported sr20's have some where around 40k miles on them.
Therefore, for only a few thousand (not that a few K is nothing, but...) more, I can get a turboed engine with 40k instead of over 100k miles on it.
My KA simply won't be up to running more than a small amount of boost by the time I can afford a turbo, with out rebuilding the motor (more $$).

This is not conclusive, I haven't even decided yet, but this is one reason.

Oh, and call me stupid or ricey, or whatever, but I like the idea of having the motor that some of the best drift cars in the world run. Its a very popular engine, and it must be for a reason. Although I'm not about to venture a guess on those reasons for fear of stating an inaccurate fact. (J/K - but seriously though, lighten up guys, were just chatting about cars and engines, not political issues.) <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

[240sxtreme]

see, that's about where I used to be....when I bought the car it had 135k on it.....I blew the engine about 2 months before I really knew what I was doing....spent 6k buying a new longblock, and labor.....I almost cry now when I think what I could have had for the same amount of money <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>

point of story, if you're engine is seriously old, then the SR20 might make more sense....if you're aware of what having the SR20 means in maintenance terms.

I guess we're not gonna talk about the lowend torque differences anymore eh? &nbsp;LOL &nbsp;I keep looking at the subject title of this post, and I'm reminded that this whole thing started with &quot;let's compare low end torque on the KA and SR&quot; &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I love us 240 guys(and gals)....simple question, turns into SR vs. KA war <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

ok....getting too tired....too easy to &nbsp;be amused.

[Archangel]

Oh yeah, the ORIGINAL topic of this thread.
Kustom, statistically speaking, the SR20 has more torque, but the power band is a little higher. &nbsp;You may not get as much of that &quot;throw you back in the seat&quot; feel as with your KA, but you will get just as much speed off the line.

Something few people have touched on is transmission.
The gearing makes a huge difference, its the way the gear ratios are set up that makes the engines feel different. &nbsp;This is more something you feel or experience, than you can really get from numbers.

[kitoro]

i like the SR20 b/c i've been in an S14 w/ one.

as for a KA24DET. i have yet to...
like another person said tho: ' I don't really dig the KA torguey nature '
it's all about preference.
i like higher revving engines. ^.^

and if anyone wants a &quot;perfect&quot; engine w/ almost the KA's torque nature and the SR20's power nature, have you guys looked at the Tomei bluetop engines? (granted they cost a hella lot)
the figures for those two engines are crazy.
