KA vs. SR could get ugly

[bp2ooo]

[quote=" matt0941 The remark about the SR replacing the 2JZGT(T)E in a Supra :rolleyes , just because someone did it doesn't make it right. It makes me think of a disabled child trying to fit two legs through one pant leg.

And bp2ooo, yoour point is pretty weak. Trying to say that it doesn't matter that there are KAs everywhere and you can pick up parts from them for dirt cheap; because it is better to buy upgraded parts. This is just flawed logic. Your KA part breaks, you have it running in a day for $50 bucks. Your SR part breaks, you have to wait a month (generalization) and $200 later your car is running. Give me a break, trying to rationalize the fact that there are alot of aftermarket engine parts for SRs makes everything ok.. yea ok. I could name so many parts on an SR that you don't want or don't need aftermarket, so don't say that cr*p.[/quote] First of all i dont understand the supra swap. Like i said i dont know why. As far as the sr20det into the rx7. The rx7 actually does really good in come races. I remember reading about it. But i agree with you that its retarded to swap out a 2jz for a sr.

As far as parts go, my main point about that was less custom work. Not everyone knows good shops, or has alot of money. if they get a ka and want a crazy trubo setup like t78 is there a bolt up kit made? not that ive come across atleast, but ive seen them for the sr. Does jun make a stroker kit for ka? They do for the sr. so what i was saying is parts are more readily available without as much custom work needing to be done. As far as a daily driver goes, yea ka would be better. Cheaper to fix and parts ever and 50 dollars to fix a motor is probably right. But for those of us who are doing this as a hobby, id pay 200 for the part if it was better and helped with performance vs a 50 dollar oem part. Not trying to start and argument, just making my point clear.

[matt0941]

Point taken, but realisticly speaking... are you willing to pay $6,000 for a stroker kit? I could have a pretty nice car with that amount of money, but each to his own I guess. Nice wheels BTW if that is your ride.

Question for anyone, My 95 240 is running with 99,000 miles now, Do you think it would be better to drop in an SR or add a T03/04 hybrid???? appreciate any inputs

[luis240sx]

And how do I get rid of this "Driving Mom's car" thing under may name?

[matt0941]

Why the hell don't you use the search function eh? I hated those guys that just said what I did but you deserve it asking questions like that, jesus.:boxing

WD please delete the last couple of posts.

[midnight brother]

Point of swapping out a 2jz for an SR and other weird engine swaps is to get exposure. Alot of swaps are for show purposes to show just how talented they are and also to blow money

[matt0941]

So people can be like "DAMN braaaa, that car used to be fast now it's slow!" :rolleyes

[bp2ooo]

matt thats funny as hell. Its not like the sr has no potential. It could probably be decent in supra. And who knows, maybe it made a significant weight difference. Anyways matt the red 240 is mine, so yes the black wheels if those are the wheels you like are mine. They are powder coated black. If you talking about the banner under my sig thats my friend integra. Limited edition rotas. Very few made.

Did you read the last 7 pages before making this post?? If you had, you would have realized that if there was an opinion to be had, then everyone already posted it. I've read several high mileage based opinions in this thread.

You also shouldn't jump into the middle of a thread and ask a question. This only takes the thread topic off to directions not originally intended.

If you would like some advice on this matter, please read through some of the threads already posted. Especially this one...Also don't forget the search function as well. I know for a fact that you will be able to find good info already on here about your question.

Daunttless, one of the Mods on this site, decides what expression goes under your screen name. You can email him if you would like it changed...lol.

[luis240sx]

Got it, wow!! a simple read the first 7 pages would work fine.

[WDRacing]

If it were that simple Luis, Would I have needed to make a post at all explaining it to you?? Believe me, I'm here to help if I can. By all means, if you can't find the answer to your questions after you've done a little research. I'll be more then happy to assist you in any way possible.

People will make fun of you with that "Driving Mom's Car" stuff Luis. Best thing to do is take WD's advice trust me on this one, just politely flood Daunttless with emails asking for it changed.

[Daunttless]

Do you think I don't read these, believe me, you'll feel my wrath. =P I get enough emails as is.

The Thing under your name is determined by your post count, if you don't want to drive mom's car, stick around, post more, and it will change. : )

[f1seb]

Now I read all 7 of these pages to get some light on whether i should swap in an SR into my 97 s14 or buildup the KA and turbo charge it. And I'm probably worse now then I was before, I mean both sides came up with good reasons but to me it seems to be split right down the middle between people. I mean I got a ride in a pretty fast SR probably the fastest on Long Island and thats what I thought I wanted until I heard the owner of that car tell me that if he had to do it again he'd go KA. And that echoed through my brain and its still in there 2 days later, and I have no idea what the hell I'm going to do......

[matt0941]

Well I was pretty much in the same bucket that you are in right now. I liked the SR and the KA and couldn't decide what to do. The determining factor for me was emissions and the legality of the motor. I am not sure what your rules in NY are but I doubt they are less Lax than in IL. We have no visual inspection but I would fail the part where they plug in the computer definately if I went SR. And thats ok cause I would probably pass the sniffer/dyno. But all that will change as of 2004 where I would have to pass the OBDII test in order to pass emissions, and that would not be doable. So pretty much KA for me, also not to mention that the SR was never registered here as a legal motor. On that note here is a question to any expert. Since MotoRex got the papers to import GT-Rs into the US does that mean that the RB26DETT is now a registered engine? Any input on this would be great, thanks.

[matt240det]

in my opinion it all comes down to what YOU want and why you want it, for some people they are modding there only car, and are limited budgets, i htink in that case a turbo ka is a good idea, esp. if you don't expect very high hp i.e. 500+ i think at the level most of you are going or want to be at it really doens't matter , i don't think anyone here is going to reach the full potential of either motor, again i could be wrong. but i know for me i chose to do the sr swap beacause this is not my primary car and i want something diffrent and i have PLENTY of time to build and source parts for it. so i htink for most of you it would be better and cheaper and easier to build the ka. The parts are available here and if you break you have little down time. but for me i'll take my lightweight aluminum block and nicer shaped valve cover :pface

[f1seb]

Well I'm setting my budget at around 10k for engine work so I dont know. The 10 would include the buy of the sr20 which would be around 6k and then the rest of the 4k would go into modifications and tuning. But with the KA now i dont know which would be better, id like to expect mid to low 12's and keep it a daily driver.

[cnichols]

$10K for the engine alone?? Call JUN and have them build you one....and with that much in the engine, I would think you could see low 11's...screw the 12's with that much money.

[f1seb]

that would cost more then 10k with shipping and then later installing it, I'm interested in keeping it a daily driver as well, I might cut the 10k budget if my goals are reached before i spend that much.

[matt0941]

Who is ripping you off man, 6k for the engine? Even with installation it shouldn't be anymore than 5k.

[cnichols]

that would cost more then 10k with shipping and then later installing it, I'm interested in keeping it a daily driver as well, I might cut the 10k budget if my goals are reached before i spend that much.

You don't have to order their all out race motor....

From JUN USA's website...

"Each JUN engine is designed and built to your specific requirements and budget."

[cnichols]

I'll think I'll go out on a limb here :rolleyes and say that JUN is the master of the SR and probably knows it better than anyone.

Leave the engine build up to the masters and put it in yourself...why pay someone to do something that really isn't that hard?

[syka24et]

Seems like the sr guys keep refering to after-market stuff and jun, veilside, hks etc (earlier post) But honestly how many of us will actually take our cars to that level. Forget about the money, the resources is a bigger issue in my book. Most of these shops make almost everything on the car (in some cases the engine managment) and then tune their own products. Don't get me wrong the sr20 is an AWESOME engine but if your in my situtation and are say going for 400 or so hp in a all around car(autox,drag,etc), and plan on doing a rebuild its cheaper to do a kit ka. then to buy a motor do the internals, then another turbo kit(the t25 is soooo small even for a 2.0 The piping bov all need replacement). {hows that for a run on sentence} Yes the sr may make more peak hp at a given hp but how much time is really spent at peak hp. Whereas you drive with TQ and thats where the ka really shines. Sure peak hp is best for drag time but remember the 240 is not really a drag car, Unless you are going to custom solid axel in the back. and drifting does not need peak hp, hell the jap tuners will tell you that. Well thats just me I have nothing aganst the sr but my situation calls for the ka.

[f1seb]

That's how I priced it at Heavy Throttle

1 Black Top S13= 2850+200 shipping1 Greddy Headgasket= 2391 Fuel Pump= 1291 3 inch downpipe=159+ 1500 in labor the total comes to 5077 dollars plus the wonderful 8.5% sales tax that they will charge 431.545brings the total to $5508.55that does not include exhaust which i will later buy and I didnt price in the hoses and other needed stuff to complete the swap which in turn will cost even more money and put me over 6kThe reason why I wouldnt do it myself there are too many people with SR's on this board and ones that I met and have somethign wrong with the engine and it's not running as it should most likely due to installation and wiring. I also don't have to tools to do something like that and would want it done once and perfectly the first time.

[Dori Dori]

Whereas you drive with TQ and thats where the ka really shines. Sure peak hp is best for drag time but remember the 240 is not really a drag car,

The KA doesn't really shine in the torque department. Maybe it makes alot of it for a n/a 4cly, but that's because it's a stroker motor. The torque curve's are ugly and peaky and are not higher when compared to a similarly tuned SR20DET. Look at the dyno sheet I posted and look at the sheet demcj linked to...both cars are running t3/t4's with similar trims and the SR20 is making more HP and more torque. Not only that, but the torque curve is sweet. The difference is that the KA made it's peak torque at around 4grand and the SR made it's peak torque at around 5grand...but that doesn't even matter because it's all relative to the length of the powerband (the SR has a higher redline).

And I'm glad you made the point that the 240 is not a drag car...but you know what, no car really is (except for mustangs!) from the factory. You make your car into what you want it to be. If you want a drag car, you can make it out of a yugo. I just don't understand why everyone on freshalloy keeps saying 'see, the KA is the better drag motor, but the SR makes the better road race motor'.

[matt0941]

wow thats pretty stupid of them to say if they are actually saying that, but i am glad SOMEONE is trying to come to conclusions. I think that is what we need on this forum, we need to be coming to conlusion rather than fighting old arguments. IE we argue but eventually say, "Ok you have a point, so I guess if you wanted a car for **** with **** budget you should pick the ***" then we would be making some progress, but yea yea I know, its easy to criticize. As for f1seb, yea I didn't mean to criticize you for having a shop do your stuff I just thought that the total would be less, looks like heavy throttle has your balls in a vice. I wouldn't recommend doing it on your own unless your very good with electrics, hell I am having a shop do my KA-T probably.

P.S. I will be using my KA-T for Race, Track, and AutoX. I don't think that the KA's powerband is limited to the strip whatsoever (sp?). And when you are drifting you don't really wanna be redlining it either...

[f1seb]

Yeah Heavy definitly does have my balls in the vice for that matter, but they are the only shop with extensive Nissan/SR experiance so that's why they can charge so much in the NY area. I wouldn't trust any other shop unless they had done a few SR swaps on their own and I talk to those owners to see if they're happy with it. I mean for the amount of money going into this project I sure as hell better be pleased with the work. That's why I'm thinking turbo the KA do some internal work and it wont come out more then 6k, I have to do some research on the internal work of the KA there arent that many after market pistons and all the valduehickeys, I'll probably talk to Paisley about the car see what they say.

[Dori Dori]

For Auto-X, the KA-t may be the better choice only because it makes more power down low...something you need in an auto-x since you spend most of your time in very tight corners at low speeds...but since the SR has a 8.5/1 compression, it's not too bad (for a factory turbo car) at making power down low. My WRX for example sucks at auto-x...I have a 8/1 compression ratio and make no, NO power before 3.5 grand. It sucks...I was constantly trying to get back into first gear (which the WRX really hates).

For track, I would want the SR for a few reasons. 1) It was designed to hold up to higher heat levels and for longer periods. 2) The sr20 is lighter (remember, the KA alone weighs more than a SR20 w/ transmission, turbo and i/c+piping)...something that matters greatly on tracks. 3) You'll be spending most of your time near redline.

For driting, or really for any high speed motorsport, you will be spending most of your time near redline! Unless by drifting you mean driving 35 mph or less trying to slide in the back of a publix in which case, I don't think it matters what motor you have. I know when I think of drifting, I think of all those cars driving around race tracks at sustained speeds well over 70-80mph...thanks but I'll take the higher revving car in that case.

[matt0941]

I am still unsure, Dori Dori would you recomment the KA-T or SRswap for drag purposes? Because you should take gearing, torque and redline into account when looking at 1/4 mile times and trap speeds.

[Dori Dori]

1/4 mile racing is a world completely seperate from all other forms of racing. In 1/4 mile racing, your wallet is your only limit. With enough money, any motor has potential to drag. In the past though, stroker motors have always done well in drag, so I'm sure the KA can do very well. Too bad nobody has put the money into making an all-out KA-drag motor, and because of this, I can't fairly say which would be better. Just a FYI, the fastest SR I know of is the 8 sec Jun car and I've seen quite a few 9-10sec silvia's with sr's from the Aussies.
