another nuby SR question

[homeslicej2]

S14 SR20 FSM states that 156psi is standard compression, 128psi is the minimum, and a difference limit b/t cylinders of no more than 14psi. This is with a warmed up engine according to the procedure.

[PyR0NiAk]

^- My 160+s were on a cold engine which would explain the reason mine were "so high" It just really strikes me as odd that that S14 motor is cheaper than the S13 motors.


Brian, I left a present in your thread.

[CRyan]

To answer the question about the fuel pump, just swap it out with the Walbro 255, that way the worry isn't in the back of your head and you've got a brand new pump and sock!

doesn't change the fact it has low compression


There's no way I would use a stock fuel pump..

And I was thinking about it, considerably, you can change the turbo to change the compression, because you are, afterall, forcing air into it, raising the compression

Now the ordeal with the SMIC. When I ordered, Patrick through it in for free. . .What are they going to do with some stock SMIC laying around?! So you may could work something out if you ask.

I can't believe you're thinking about doing a lame SR swap for your senior project. Not only are you dumping cubes, which we've already acknowledged is a loser idea in the "other" thread, but you're forgetting an entire realm of options as well as repeating an overly done swap.

I must ask, if the KA is being pulled out, which isn't a bad idea IMHO, why the hell would you ever install a smaller motor like the SR20? With the budget to make one of these little bastards make any real power you could do a simple GM 350/any transmission swap and have a car seriously fun to drive. No one can argue getting that happy feeling when immediate torque is applied to your whole body every time someone stabs the go peddle even a little I smile like a kid driving his Dads ride on lawn mower for the first time every time. You're not getting that smile with a 2 stroke...I mean SR20

Lets face it, the SR is a torqueless p**** compared to the 350+ft lbs of right now torque available at throttle tip in with a simple carb setup and some cheapy Vortec heads bolted to a good ole 350

Which btw can be delivered to your door for under $1000/short block should you manage to make more power then any 240SX chassis should handle without modification for torque twisting. You'd think that would be enough argument right there, but I'm sure someone will argue that less is more...you don't see pron stars with little d!ck for a reason bro. You might even hear that less is "more efficient"...you try telling her that buddy It's called an UPGRADE for a reason

Sack up and take the road less traveled and you might even be remembered. Don't let these Sallies talk you into being lame. We have guys in the Hybrids forum doing fantastic swaps right now. One is a DIY 383 Stroker with a turbo big enough to feed kittens!. FFS man...don't be like all the other sheeple. Step out of the box

WD

God I'm so sick of this "why downgrade to a smaller c/i engine" NONSENSE. Though your reference refered to in bed was quite funny, it doesn't seem to fit quite well.

Let start with something basic. The stock 2.4 liter engine. 150/160 hp brand new. What happens when they drop off that half a liter! OMG ITS MORE HORSEPOWER. I wouldn't expect someone from the hybrid forums to quite catch the concept, but they call this engine a great PLATFORM engine. As in, its simple to swap in, and its even more simple to make power with it than its USDM counterpart.

And I will agree, this swap is done a lot. Which is ONE MORE REASON he should be doing it. The countless amount of information, not only on this site, but others, will allow him to do this swap in not only a timely manner, but be able to receive the better grade and NOT have to take the chance with fabricating brackets, etc. And just drop the engine in.


Though this statement is radical, it can still be seen. Cubic inch isn't everything, note the 18,000 RPM, 800HP Formula one cars. Oh 10 cylinders, 2.4 liters. Something less radical would be to point out the 125 hp per liter Honda S2000. Now point out to me a STOCK GM engine that makes 125 HP per liter (naturally aspirated in this case, of course).

And to a degree, I will agree that this "instant gratification" is great when you have that torque right there at your foot. BUT, though you have the engine, do you have the rest of your driveline?

This engine swap is done because the car is up to bill for it. Its pull out KA, drop in SR, ohh a little wiring, and boom. You have a car that is respectably faster, took one quarter of the time, and something that is presumably more reliable than some hybrid swap (in his case).

[PyR0NiAk]

It's so funny that you brought the efficiency debate of Horsepower per Liter. Check my sig. I earned that title because of my rants in the KA-T section Good post CRyan. You made me proud.


Before this turns into a HUGE KA/SR war, I figure I should point out that I've been harassing a couple of the KA guys in the KA-T section so them coming here is totally expected. Especially WDRacing.

The KA-T thread if anyone wants to join me.

[CRyan]

Ahh damn! I didn't know that. Well hopefully he takes it as a debate and not some low blow or anything.

[PyR0NiAk]

LOL It's all good man. As long as it stays an educational debate and not a retarded "my motor is mad jdm tyte and yours is a truck motor" s***, it can continue.

[CRyan]

booo. My next clause was to inform him of one of the main reason the SR is better, because "tight" can be only spelled one way. With a y.

[WDRacing]

I love debating this particular topic. I'm in the middle of a bunch of crap, but I'll be back later to educate you...lol. Real quick though..

Efficiency arguments are for motors that make no torque and give you zero smile factor. Yes the blah blah etc etc *insert random 4 banger* makes more power per liter then any old 350. I never said anything about efficiency though. I"m referring to actual power produced when it's the most useable.

Pyro said codyace's Sr was a good build...then I showed him that it didn't even hit 200 ft lbs until almost 4000 rpm. Where as any generic half decent 350 makes more then 300 from 1800 on up and it can usually gen up another 120 ft lbs by where your SR is just breaking 200.

Think about that for a moment. I'll be back later to continue. I'm not coming at this from a KA or Hybrids angle, I'm coming at it with a "why SR?" angle. Cause seriously, you're not gonna tell me that the SR is the best of all the available options are you?

[PyR0NiAk]

^ Amusing when you're desperate enough to win, and you know that you can't win using the KA, so you have to ditch your own motor choice and go with an entirely different type of debate.

I won't say that the SR is the greatest engine ever or anything of that nature. If anything, I can agree that any naturally aspirated V8 with torque at idle is great. As you said, "smile factor".

My arguement isn't between whats the better engine, but whats the better engine for this guy to be doing. Apparently, he has a couple (assuming) years experience and has never done an engine swap. This is what makes the SR20DET a great engine. Because its easily acquired, easy to swap, and easy to give yourself (and a grade i suppose) a big smile.

Yeah, I might have smiled quite largely if when I did my SR swap it was an RB, LSX, etc. but I was just as happy with it, because I was able to do it with the conditions I was in financially and experience(ly) capable of. I kept it from becoming a harsh task and enjoyed it. Though I have been more than impressed with the engine, I see this as it will become a "whats the best engine" when most of these topics related to it never take in the real world attributes that come with the figure asking the question. Catch my drift, now?

[WDRacing]

I'd ditch the KA in two shakes if I had a V8 on hand with a transmission to bolt up. I've never suggested other wise.

I can also tell when I'm being bated.

FAIL

[CRyan]

I don't fish though?!

[WDRacing]

That's cause you have an SR...duh.

[PyR0NiAk]

Yeah, keep in mind. WD does carry a boat anchor under the hood of his car. He's always ready to fish.

[CRyan]

True story. I live in mississippi, and the big "redneck" fad now is having either A)an arrow (that you shoot) or B)a fishing pole as your antenna.

[93 Chuki FB]

That's cause you have an SR...duh.

i swear, u and PyRONiAk ALWAYS turn my threads into SR vs. KA, now its SR vs. KA vs. 350-383 GM lol. i have plenty of experience with engine swap and working on 240's in general, my first choice would be the 350 swap just because i would make a ton of power. But after talking to my auto teacher, he said that he's not helping anybody (students) with engine swaps anymore because some kid (Honda, he has a 1991 DA Integra) decided to do a LS swap (B18B1) into his POS. He didn't do any of the work, instead the teacher did the whole project for him and hold him to get the hell out of his shop and never come back. So when i asked him if he could help me since his classroom is a 3 bay garage with 3 car lifts and like 6 of those NAPA tool boxes that cost like $6k, he has ever tool imaginable. He said he would love too but hes not going through this whole bull s*** "senior project thing" since i don't have access to those resources i cant really do anything custom. I almost have all the parts for a KA-T but no car to put it in, i dunno we will see, i do have a 1975 280z that runs like s*** so i might swap the KA-t into that when its done but thats gonna be farther down the road.

[PyR0NiAk]

So now you're doing the KA-T. Dude, you sure you're not female? You change your mind more than my wife.

[93 Chuki FB]

So now you're doing the KA-T. Dude, you sure you're not female? You change your mind more than my wife.

what no! i have to do the SR swap, i did the paper work for the project last week with my counselor so its final. But before the SR swap i was gonna go KA-T, so i gathered parts and i still have them. And i know, usually im super confident when it comes to making decisions, this is literally the first time ive changed my mind on something more then once. But what im saying is, since my KA runs perfect, there is no sense in letting rot in my garage when i have a 75 280z that could use a new motor and i do have like 70% of the turbo parts. I can have more then one project lol, but only one can count for a grade so the 280z is gonna be a side project for me and my little bro to mess around with. So their u go W D, im gonna do something thats mad JDM TYTE YO!! and something that out of the box and creative.............speaking of creative, check out this vid of a guy with a 280z that combined 3 ka24de heads to make a DOHC head for his l28 engine, he then stroked it to 3.1 and then added twin turbos

Even makes the timing chain rattle like the KA's lol

i swear, u and PyRONiAk ALWAYS turn my threads into SR vs. KA,

It's because your threads are so contradictory that we figure we should bring in a topic that will easily stay on track.

[93 Chuki FB]

u may proceed to burn in hell PyRONiAk, lol i saw what u did to my KA-T thread, i thought that was funny. I cant change my mind anymore so SR it is but i still have my KA and most of the parts to still turbo it, and a 280z that could use a new motor so we will see

It's almost like you know you're making a bad decision by swapping in the SR. Remember you don't HAVE to do anything. No matter what these guys are telling you, they do some from some dilluted thought process where the the SR is actually a better motor then the KA. But only argue things lie efficiency per cc of motor. Well if the motor is smaller, the you're getting more use out of a smaller d!ck. Congrats you just became average. Welcome to JDM Fanboiville...it comes with an addiction to stretched tires and suspension that pops out your fillings.

No one makes fun of Honda's anymore dude...they make fun of guys with poorly running SR swapped 240's. These guys don't like to admit it, but that doesn't mean it aint true.

You can never say you weren't warned and I'll expect a thread saying so within 6 months.

[PyR0NiAk]

I like meaty tires, thank you. And yes, people still make fun of Honda's. Although, if you look in 240gen, most of the fanboy posts come from the guys who OWN KAs and TALK about swapping an SR. You seriously need to resort to small d!ck comments to try and prove your point?

[PyR0NiAk]

W D dont worry, im gonna do what i want. A great example of that is how i changed my mind so many times (FOR THE RECORD THIS IS THE FIRST TIME THIS HAS EVER HAPPENED) But like i said i only need a couple of things to get my KA boosted. And my mom and dad (go ahead and flame, but we all know if ur parents offered u money or help u would take it) offered to pay for the SR swap so i can have both. My little bro wants to trade his integra for a 240sx so the KA-t can go in that or the 280z. Speaking of 280z i have yet to post pics of it.



I couldn't resist buying it, $175 and i drove it home

[PyR0NiAk]

I almost got a 280z as my first car... Thing was rusted BAD underneath... Make sure you check your frame rails. Body looks good from what I can see.

[CRyan]

Whoa whoa whoa now.

You'd be quite surprised how RARE it is to come across an SR powered car here in the capital (and largest) city in Mississippi. Thats why I did it. Not to follow some "fanboi" crowd, but to, again, have an engine that accepts aftermarket parts better than your KA.

And you have to admit, having a KA is still like having a small d!ck.

Only difference is the KA tends to blow prematurely!!

I don't wanna argue which motor is better, the KA or the SR. But if you're going to say something at least make it some what accurate. The SR doesn't do ANY thing better then the KA. A poorly tuned SR will pop just as quickly as a poorly tuned KA. The KA's factory rods bend at right around 500 whp. Giving it a reliable 450 whp capability.

The SR accepts parts better? What does that even mean? Somehow the KA doesn't accept bolt ons???

There are more aftermarket parts for the SR, that's truth. But the KA has more then enough available for any power goals or application.

If you're going to keep saying the SR is better blah blah blah, get your facts straight. I understand this is the SR forum, but that doesn't automatically make the SR better then whatever motor it's being compared to. There are many very successful KAT's putting down great power on stock internals with a simple ROM tune. There is no magic involved with either motor and I want unswallow my lunch every time I read about the SR making more power then the KA. Well yeah it does retard, you're talking a boosted motor compared to a NA motor A boosted KA with a small T3 will make more torque then the SR at the same amount of boost. I already explained that torque is what moves the car. So the SR is no friggin better then the KA, it's a stupid argument and it's been beaten to death.

Both are good motors and everyone has a preference, but preference is the only thing that truly separates the damn motors.

[PyR0NiAk]

lol... I think he actually got to you with that one, Brian. Let's not forget, these KA vs SR debates were started for fun. I, in no way, am being serious about them, and I don't think Corey is either. (CRyan)

[Street_Science]

Here's a better Idea, buy an already running 240 with an sr20 swap and a few mods for $3-4k, Sell your car for $2k...
take time off from doing the swap, pick up the sexiest group of sophmore repeat sleezes , go for a ride, do a few donuts, get em wet, burn one and bring them back to your garage for some " hands on learnin' " ..... OOOO and you will also get an A and graduate high school, with some good ole' high school memories ......
