sr20det or ka24de

I'm sorry if the dots confused you, I just felt like leaving the unapplicable info out so as to shorten it. :rolleyes

And this is a thread about Turbo engines. I made a post about said subject. And even if I WERE talking about an NA engine, why would I even mention block strength, forged internals, and "PSI?"

Althought I would be happy to make an argument for an NA SR over KA. I just enjoy arguing and will take whatever side seems to be losing at the time.

It's good to see that you atleast read before you post....this discussion has already been completed.

This thread does not need to be deleted. Yes I am elitist, but this is actually providing me with some entertainment. Run along jesters, you're making this fun. And Blake, are you sure there aren't any VET's in RWD, cause from what I remember the Xtrail has an SR20VET...now if its transverse mounted awd, then I stand corrected. Either way, likelyhood of an SR20VET swap into a 240 is lingering around 0%. kthx.

[Cyberkreig]

this thread = lock me cuz its been talked about before.

there is one rwd sr20ve. likelyhood of you being wrong is around 100% kthnxpwned

[NV_JSmith]

lol every one donate 10 dollars to me and yall will see a sr20vet rwd 91 240sx

[SeVa-S13]

Yeah, came in some Xterra/Pathfinder thingy so I heard...anyone have actual proof?

[Cyberkreig]

that was AWD transverse mounting, but feel free to play again.

I've been talking with someone else from nico about this for some time now, doing my research and talking with shops & motor importers. I had planned to have the first running VET in the USA and maybe the world. Its not impossible, but it seems that no one cares enough to do it. Probably because the money could be better spent on a big turbo & fuel system for easy HP. I just wanted something really unique with a wide powerband.. then i got into a car accident and was out of work for a while. Amazing what that will do to your savings.

[SeVa-S13]

Oh, you mean the freaking frankenstein conversion thing? That hardly counts.That's like saying Aries' S14 came with the 350. Sure, it can be done, doesn't mean it ever came that way, sheesh...

[Cyberkreig]

ah ah ah, I didnt say it came that way. I said Zero-S was wrong, in reference to Quote »likelyhood of an SR20VET swap into a 240 is lingering around 0%[/quote]Notice he said swap. he is wrong.

[SeVa-S13]

Oh, well you can stomp Rob all you want, just aslong as I'm always right. *puffs out chest* :pface

[Cyberkreig]

*refers to your icon*

and i'm not stoping. I'm correcting, i just chose to use the same intar-web language kthx

[SeVa-S13]

Don't be modest now, pwn Rob like there's no tomorrow. I <3 intraweb speak.

[[Zero-S]]

K sorry cyberkrieg. I was considering an sr20ve swap into the 240 at some time, then I heard it was awd transverse, so I was like nvm.

[240Knightrider]

I dont care if this post has been talked about 50 times, it wasnt done by me. That being said I started a new one. You may be able to read over something but when your invovled you tend to remember it better. I agree pure entertainment.

[[Zero-S]]

Blake you're a friggin e-thug.

[Dattebayo]

Or you could use the search button, like the rest of the informed community. sheesh. It's like talking to a wall! at least we got some entertainment outta this one...

[SeVa-S13]

It's not like I did any of that to post whore out of boredom or anything.... :batman

[Cyberkreig]

and i certainly didnt jump in with useless smack talk to post count ++

[Dattebayo]

Well so long as we all know our responsibilites...

[Nathan]

This must be by far the stupidest post I ever read. Not because of what he said but if you check out his cardomain site, the last page he wrote that he is rebuilding the KA24 Engine. Can you say :withstup

Actually, speaking of that, I need to update it The built block is in, the turbo is on, the front end is back on, IC mounted, piping made...its getting the *****IN nice custom exhaust put on as we speak. Soon I'll go nuts with the digital camera and make a big car domain update.

[StrangeLove]

+1 *****es

[SeVa-S13]

W00t for Nathan!

(Read: +1)

[[Zero-S]]

Hope to see updates soon Nathan.

oh yeah +1 (like I need it)

This is the first I looked at this thread. And it strted as a legitimate thread and turned into a rather poor one. Not because of the original question, but because of the responses.

As I've said before, if you don't like the topic, don't read it. If you want to suggest a search, fine. If you have nothing productive to say though, why post?

I'll stop my rant now.

As far as the whole SR vs KA debate, it is quite subjective. The KA is no less of a motor in my opinion. Comparing NA versions will tell you that. While in the US, the SR has about 15 less HP, Japanese version see about 150 HP. Turbos will for a largepart proprtionately increase the torque based on the pressure ratio in the turbos efficient range of boost. Outside of that, it may struggle a bit more.

Out of the box, I'd go with a KAT first. You can argue tat the SR comes with one, but they are rather small and inefficient turbos, relatively speaking. KAT kits generally come with at least a T3/T4 and in many cases a straight T04. Because of this, KAT's tend to have more power. The SR-T requires that you increase boost to try and match the power of a KAT. Certainly, you can upgrade the turbo, but at what cost? Depending on the set-up, if you chose a turbo that closely matches the flow and efficiency of a typical KAT turbo, then you would probably spend at least as much total cost on the SR if not more. So from a cost standpoint, the KA might be a better choice up to an extent. For extreme power, the SR has a lot of research already done by large companies and parts availability for increasing power is much better. The KA has relatively little research done in the seriously high HP department, but with the understanding and application of turbos in the aftermarket becoming higher and higher, it's growing fast. Both motors are plenty strong. Both need to have internals upgraded at some point. If you are looking at it from a HP standpoint, then I'd look at the goals you have and the costs involved with each to get there. If from a drivability standpoint, well, that's just a matter of preference.

I usually agree with what you post but this is way off base.

clearly the SR (t25) will have to run a higher boost to match the HP of a more efficent turbo. This has nothing to do with the motor the turbo is bolted to a t25 can not compete with a t3/t4.this point is moot.

aside from that your cost estimate is way way off. average sr is in the 2800 range. Cost of the xs ka turbo kit is 3999 (t3/t4 kit) from enjuku. the greddy kit is in the 2800 range. You can read the details of this kit here http://w1.igateway.com/clients...=form

either way 2800 is spent and you are right in the same HP range. Ka has the advantage of a better turbo at this point. both are limited by their fuel system, both need tuning (the ka more than the SR as the ka is not an out of box application)

the Sr has a 400whp proven bottem end, the KA is still unknown in this area. the SR has a quality factory headgasget, the KA's was never designed for boost. Not at all to say that the KA cant, just that it isnt as tested.

(note: an upgraded turbo for the SR(bolt on style) can be had for an additional 1500. )

[Onizuka]

I wont argue which is better out right, but some of my reasoning for buying a SR:

-a SR20DET is lighter than a KA24DE-T by 50-100lbs-Im way too lazy to replace internals when my goal is only 280-300hp reliably.-my KA had 144,000 miles on it

Either motor is extremely capable, as is the CA18DET, FJ20ET, RB20DET, RB25DETT, and tons of other unbeleavibly awsome nissan motors that are always absent from these retarded threads.

[usdm_180sx]

The ka will have more torque and rev lower. The sr will be smoother and rev higher. The sr's internals are good for 400hp and the ka's internals should be replaced before boosting more than 7psi. Not "have to" but "should" to be safe since it's your money. Aside from that the questions becomes: "How much do you want to spend?"

[Onizuka]

The SR is a pretty rough engine if you compare it to a CA or RB series motor, and you cant factualize that the KA will have more torque or the SR internals are ALWAYS good till 400hp.

This is my main problem with these threads, everyone trys to make everything a fact (myself included), when there are just too many variables to have something always hold true.

I was talking strictly the differences of going with an SR or KAT.

And no, the KAT with a typical bolt-on kit will actually have more power than a stock SR. At 6-7 psi, the KA pulls about 230 RWHP. That works out to about 270 HP at the crank assuming a 15% drivetrain loss. The S15 SR pulls about 250 HP at the crank and while I do not kno the going rate for these, I'd assume it's still pricier than the S14 or S13 SR's which tield less power. To achieve similar kinds of power with an SR, you can either increase the boost or you would have to swap turbos. The latter would be my preference and would likely put me over the cost of a KAT.

And just a correction, despite what XS Engineering's site says, the XS kit uses a T04B, not a T3/T4. I have this kit in my car.

[Cyberkreig]

i'm not calling you a liar, so please read my posts as conversation not argument.

I have trouble beleiving that the ka pulls 230rwhp at 7psi. this would mean that the greddy and turbo XS kits advertise underrated HP numbers. Even supposing for a moment that KAt to4b & 7psi does make 230rwhp. or around 270crank HP, this is right at the very limit of a 370cc fuel system. Remembering that fuel systems are limited by HP not psi. Any of the SR's with the boost turned up can match this. YES 230 @7 is better than 230 @ 14 BUT my point is simply that $3000 spent on an sr or $3000 spent on a turbo kit puts you in teh same neighborhood Hp wise.
