2.2 stroker???

[pushnlacs]

hey what up?? i just was wondering about something and was hoping you could help me out.

first, does hks still sell their 2.2 kit for the sr?? also iv heard about people taking their sr to 2.4l"S. how would they do that just bore it out to 2.4?? and that brings me to my last question whats diffrent about stroking a engine out to a larger displacment with a stroker kit or just boring it out?? thanks

[pushnlacs]

no one huh??

[Hijacker]

i just read that AEBS is releasing (or has released, dunno yet) a stroker kit for the SR. New cylinder sleeves and a sroker crank brings it to a 91mm bore and 91mm stroke to equal about 2367cc

EDIT: After checking the article out more closely, it didn't specify if that was for the USDM SR or the JDM RWD SR. The only picture of the block looks more like the FWD version. It shouldn't make a difference as the SR internals are swapable from the USDM to the JDM, but I thought I would note that

[bcar240]

boring a cylinder involves machining the head to make each cylinder physically wider, so there is more displacement. Stroking involves changing the rods and crankshaft (and maybe piston) to allow the pistons to move up and down more to create additional displacement. A "square" combustion area is usually ideal, i.e. cylinder widths are about the same as the piston travel. So, it would be most effective to do both a bore and stroke, not just one or the other. However, there are some who say that an SR20 is most efficient as it is, and boring and stroking won't do much for it. I have no experience with SRs, so I can't help ya there...

[masticatingcow]

Nissan already made a 2.4L 4-cylinder engine, and you know what? It comes stroked from the factory. LOL.

But seriously, I think Tomei makes a 2.2L stroker kit for the SR, so I'm pretty sure you could get that if you REALLY needed to...

[pushnlacs]

so the sr's that are 2.4l probly have a 2.2l stroker kit and then have been bored out anouther .2l's right??

and yea nissan did make a 2.4l 4 (the ka) but i rather have a 2.4l sr just for the sake thats its overall a stronger and more proven engine.

the main reason i asked was. though the sr at 2.0l will probly be perfect for my goals i was just wondering cause at first i just want to get the sr to 400hp at the crank but later on mabey take it to 400whp. anyone have 400whp on the sr??? is it laggy as hell?? how is it for street use??? thanks

[FAST-DATSUN]

AEBS and Jim Wolf have 2.3/2.4 kits bored and stroked to get there......

[masticatingcow]

...but i rather have a 2.4l sr just for the sake thats its overall a stronger and more proven engine.

True enough, the SR is a proven engine, but when you say "proven" you really mean "proven in 2.0L form." The SR will probably suit all your needs just fine at stock displacement. Many tuning houses have put down 500whp with the SR on stock internals. Yeah, I didn't believe it either, but it's true.

You suggest that you want a streetable engine, and I think that's a good idea. Generally, though, the most streetable engines are those that are carefully tuned and modded as necessary. A streetable 400whp is attainable, but count on spending a thick wad of cash if you plan to do it, even in 2.0L form.

[Def]

The last thing I'd do to a primarily street driven SR is stoke it to 2.2L. Higher piston speeds DOES lead to a more often rebuild, just look at Integra Type R guys that zing their ~88mm stroke motors to 9000 RPM and above. They are lucky to last more than 30-40k miles at those piston speeds, and those are street miles. You just can't get past the fact that you're passing the average Formula1 piston speeds of the late 80's/early 90's, and sometimes approaching what they run today but expecting the engine to last 200k miles. Sorry, just isn't happening.

On the subject of displacement, my recommendation after driving both engines(drove the KA stock for a month or so and have had the SR swapped for a few months), just stick with the KA if you want displacement and 2000 RPM stump pulling torque. The SR20DET feels just fine to me going around town, but my car is pretty light.. The last thing I'd want to do is spend a huge chunk of change on making the engine less reliable.

Oh yea, 400rwhp isn't all that hard on a stock block SR20DET if you've got some cash to throw at it. It won't happen for $1k ontop of the engine though, think more like $3-4k or so all said and done. That said - you ever driven or been in a car with near that much power? The number sounds nice, but that's approaching a ridiculous level on the street since you SHOULD be able to run a high 10/low 11 second quarter mile run with that much power and traction(slicks). That's reaching scary power levels there for the street.

i hear some people say stay with the ka for dicplacment and tourqe because of its 2.4l but to turbo it and then build it up to hold the power a sr can you will have spent more just getting the ka ready for your goals then you would to have a 400hp sr. also sometimes if a car is done right 2.0l can have just as good response and low end as a bigger displacment engine. because "technology, is the replacment for displacement" plus talking with phase 2 they said the s14 sr20 will put out even better low end than most 2.0l's because of the vvt. so i think ill swap out the ka and go with the sr.

I think the jury is still out on that one. SR people bash the KA crowd for having to rebuild their motors for reliability, but if you think you can take an SR out of a JUNKYARD and expect it to run reliably at 400whp, you're dreaming, man. Building an engine like that takes money, my friend, SR or KA or RB or whatever.

You also mentioned 2.0L engines having the same response as a 2.4L engine... if you ask me, that would be a crappy 2.0L engine. If we're talking about SRs and KAs specifically, I think you should be worried if your SR responds like your KA, personally.

[bcuz]

Some people just like to talk out thier a**. If you have a well taken care of KA it can hold boost just as long as an sr. SRs are NOT bullet proof. If you get a KA and build it then turbo it, by my numbers it can come out cheaper and perform MUCH better. Also you have readily available parts incase something goes wrong... that means you ownt have to pay 300 bucks for a MAF should you need one.

ka = 50$making ka bullet proof = 3500-4500quality turbo setup = 3500-4500

sr20 = 3500 shippedreplacement parts that are sure to be needed = 500 (and thats a low estimatequality turbo setup = 3500-4500

the KA setup has more torque by far and its built like a brick house and can hold way more boost now, the sr is still allllll stock inside

Is it REALLY cheaper to get an SR? NO... dont let JDM fanboys sucker you into thier little twisted form of reality.

[pushnlacs]

im not letting jdm boys talk me into nothing truth is though having someone pop there hood and seeing a ka all done up and turboed doesnt impress me. all you did was take a engine that was never ment to be for performance and made spent money making it something its not. now a hood pops and i see a done up(hell even stock) sr20, thats impressive. its a nice looking engine and was ment for power.

also i dont get how a built ka is cheaper than a sr. a s14 sr cost 3500(2500 for a s13) and thats it you got a sr for 3500 and can get to work on it and not have to worry about building it handle boost or 400hp. the ka would cost you 3500 for the turbo kit(your already spent the same or even more than a sr) plus add the cost of building it up befor you can take it to 400hp. i wouldnt buy a 240 unless im swapin a sr in cause even if i had a 500hp ka i wouldnt be happy knowing im still pushing a ka. theres no pride in it, its like making a caviler go fast it can be done but its still a cav. without the sr the 240 isnt ****. also why would you be worried if your sr had good response?? thats the pint of tuning and matching up the perfect turbo, to get perfect results and response.

[Chingon]

didn't we have this discussion before w/the same moronic arguments???? I could swear we did...

[pushnlacs]

moranic?? wtf u talkinm about??? if your sayin my points were stupid thats cool u go n pimp your ka powered 240. ha

[masticatingcow]

moranic?? wtf u talkinm about??? if your sayin my points were stupid thats cool u go n pimp your ka powered 240. ha

It's moronic because people sling the same bul1sh!t "knowledge" around to back up what they think is the better engine. This argument has been held countless times before and quite frankly, no one can convince the other side of ANYTHING because people have their heads too far up their own a55es to listen. That, and all the SR group talks like they've done more SR swaps than most Japanese tuning houses while the KA people talk like they've built reliable turbo kits for less than the cost of the KA itself. There are too many reasons that it's a stupid discussion, this KA vs SR crap. Plain and simple... I'm sure it's nothing personal.

You talk a lot of trash, pushnlacs, and I think very few people appreciate your attitude. Try and ease up a little and maybe you'll get a better response for your fellow board memebers.

Did you read what I said? thats why its cheaper, cuz for the same price you have a built motorthat can hold 25lbs of boost all day and then some, or you have a stock internal sr20 with a turbo kit...

Dont ever again compare the ka to the caviler, first of all, one is a motor and one is a car, second the caviler is just a low blow.

And just so you know.. you can take your valve cover off take it to a body shop, have them sand blast it, then paint it red with a nice glossy clear coat for about 70$. Besides that I dont know why a sr is a "nice looking motor" that was just a mouth full of rice right there....

[Hijacker]

okay, boys. settle down before this thread finds its way to the trash heap.

One thing everyone has to realize is that every motor has potential. The SR and the KA both have their strengths and their weaknesses. I get sick and tired of seeing people spout out that the KA sucks because of Blah. Or the SR sucks because of Blah. They're both great engines built by a company known to make very strong motors. Leave it there. If you like the KA, don't bash the SR. If you like the SR, don't bash the KA. The only motor I'll agree to bashing are Ford 4 cylinders

If you want truth that any motor has potential, I've seen a Yugo that was taking FTD at autocrosses.

[Hijacker]

if you think you can take an SR out of a JUNKYARD and expect it to run reliably at 400whp, you're dreaming, man.

Nobody seems to understand that point for some reason. Many Silvias and 180s end up in the junkyard because of engine problems.

[pushnlacs]

ok for one i dont talk **** until some one pissis me off. im a cool guy and dont like starting **** but ill push back if im pushed thats all.

and about the caviler ka comparison point was its making something fast that wasnt ment to be, and that brings me to ford 4 bangers in the new super street theres a 400hp fucos built by the same guys that built the 1000hp evo 6. yea its 400hp but its still a focus and was never ment to push 400hp just like a 240 w the ka still in it. thats my opinion.

and as for nice lookin engine your just an idiot to say that a nice looking engine is rice. the sr done up looks better than a painted valve cover on a ka iv seen both and no matter what the ka looks like a weak 4 banger that was just ment to get u around slowly and u tryed to make it fast while the sr looks and is a high performance engine. if u wanna build up the ka, do what u got to do but dont try to convince its the better and cheaper(well "cheaper") choice. t just sounds like every one that bishez about the sr and u should build up the ka..bla..bla... are people that couldnt get a sr for what ever reason and are tryin to justify the fact they got a ka.

[Chingon]

I don't think anyone has problems w/the sr. PPl just have problems when someone who doesn't seem to know much about anything comes spouting misinformation about how the ka was not meant to be fast or doesn't look as "nice". What is this superior technology that makes the sr go fast I ask?

Besides perhaps a better head design, I really don't know. You have a restrictive intake manifold, a so-so fuel delivery system and oh my!, forged pistons. The sr is a very capable engine, but just like the ka, not in stock form. The sr i'm sure came in na form before it was turboed, so I fail to see any argument of "not built for boost". Just because nissan throws in a turbo manifold, a turbocharger, forged pistons, and a reprogrammed ecu, doesn't mean anyone and their grandpa can't do the same w/their own ka and get similar results.

And what's so special about the looks? It looks exactly the same as a usdm sr20de but w/a snail and a red/black cover. If you like the looks of the engine, then get a '93 sentra se-r. No engine looks that special, unless it has a massive turbocharger, itbs, adjustable cams, wicked plenum(s) or some weird shower injection.

on the ford topic...we seem to be forgetting the escort/focus cosworth, the last of which won the Mexico WRC this year.

Must be that damned thing they call a piston. or was it fuel? j/k

[brisknfade]

The guy wants his SR, just let him have it. There probably won't be anyway of changing his mind anyways. Plus I'll have the satisfaction of knowing that theres another KA out there that I would be able to get my hands on if i were to ever need it ;-)

And yea, Tomei does make a 2.2 stroker kit, so does Toda, but they have been pretty expensive everywhere iv'e seen them, around 2 or 3 g's. That quite a bit for an extra .2 l's You'd be better off spending that extra cash towards an S15 SR20, at least then it won't have that many miles and is somewhat better then the 14 and 13 version.

Weak engine my arse

Take your SR and shove it.

[pushnlacs]

i dont know wtf is up with yer love for the ka. its not a performance engine plain and simple and you can go and say the sr is only cause nissan did this or that...well no ****, thats the point.

perfect example of the sr is the better engine is for one thing nissan kept the sr20det in the japan market but gave us the ka and like i said you can soupe up a caviler to and make it fast but weres the pride?? all the us spec 240 is, was nissans "caviler" low price eco coupe.

also if the ka is so great why has bearly any after market focused on it?? why as any project car that a japan tuner swaped a ka into just for the hell of it been scraped???

and why isnt anyone saying "damn i wanna swap a ka into my ride"??? if the usdm 240 came with a sr20det would you swap it out for the ka?? theres no way in hell youd be like "you know what im ganna take this badass sr20det out and drop in the engine from that pick up over there,hell yea." the agument for the ka is from people that for one reason or anothe can or wont drop a sr into there car, nothing more than trying to justify their bad desicion. if anyone even says they would swap out a sr20det for a ka if the us 240 had the sr is a f'in lier.

oh and to say no engine looks special or that the ka looks the same as an sr your an idiot too. because if you cant tell the diffrence between a ka done up and a sr done up then you shouldnt even be around a car. so dont go and say im misinforming anything cause i dont know everything but i also dont speak what i dont know . i speak the truth and if you dont like it thats to bad.

[kamikazestorm420]

i dont know wtf is up with yer love for the ka.

are you PMSing sir?

wtf is up with your love for the sr? and that is not how your spell "your"

why dont you calm down.

why most people wouldnt swap a ka in their 240 if it came with the "almighty" sr20 stock is that it doesnt come turbocharged from factory.

if there was a ka24de that was turbocharged from factory ..

i would take that sr20det in the 240 and swap it out to the ka24det anyday.

and have you ever even rode in a ka powered 240? by your responses i dont think so.

i cant wait to see all you JDM people running sr20 come up to me and rev at me and the only thing your going to see is my kouki tail lights.
