shit, go for broke, rb26

WTf. You you are taking a factory turbo engine out and putting in a na factory engine to make it turbo. Seems backwards to me. But yes. It is true all 240 owners are Down right crazy

9/14/2011 12:59:04 PM

^^an extra .2 liters, a gajillion dollars to find one in any decent shape, and the hassle of finding an rb25 trans to make it RWD... haha nah, unless i have money flowing out of my ass, i think building/boosting a KA wins this one.

^ a factory na motor that came with .4 more liters than my SR, has an iron block, and has cam on bucket (a.k.a. no stupid rocker arms). yes. thats exactly what i'm saying.

Did I read your thread wrong? I thought your s13 has a sr20 in it already. You can use a ka trans or RB20 trans. Just swap the bellhousings.

Rb25 trans requires custom drive shaft.

Ka24de's don't have oil squirters and sound like pickup trucks

9/14/2011 1:07:39 PM

swapping back a ka for a sr its just kinda weird..

i mean the KA is a great motor and turbo's OK but it doesn't like revs.

RB25 is the best all around, revs like an SR has the displacement of a KA and doesn't cost like an rb26.


but really i'd just fix the sr and boost the shit out of it...

I mean the KA & SR are engines that i'd put a GT30r on max for response and power but the rb25 i'd go bigger.

9/14/2011 1:17:34 PM

i do have an SR. it revs fast, it's super smooth coming into power, yada yada. but bang-for-your-buck, there's nothing like the raw torque of a boosted KA. my housemate and a good friend down the road both have KA-T's. they're an absolute blast and can be "done right" for about the price of an stock SR swap.

that said, this stock SR has seen quite a few hot drift events, a couple overheating scares, and general daily driving for a year and some now. still runs strong as ever, even now with an s15 turbo on 15psi. so i can't complain much

9/14/2011 1:31:14 PM

Dammit. Get this Carolinanissans pipe dreaming talk put of here.


I went rb20. Heavier, more weight up front. But guess what its in a heavy vert already, a long block is 1ooo flat and it has that sweet straight 6 scream at full boost at my raised Redline of 8k and top dropped yea I like it. If u want to go with a pickup truck engine. Whatever dude. You already have the SR setup. Just build it better if u want. Don't go following your brosephs with the ka's unless u are getting some kind of stupid deal and a lot of spare parts/help.

9/14/2011 1:55:28 PM

I guess i have rev envy from having my EJ-25-t its a tq monster but feels like its running on nuts and bolts near redline.

9/14/2011 1:56:17 PM

Yea mine is dog shit down low. And cams run out at like 6500. But it's super smooth up top. Just seems to want to live up there

torque = good.

turbo ka = bad.

9/14/2011 4:31:57 PM

I'm not saying a turbo ka is bad. But if you have the sr, the stock sr bottom end holds more power without coming apart than the stock ka bottom end. So build both motors an the jun sr22det is one of the best motors ever but the ka just won't rev when I was looking no one made a decent intake for it and it simply won't rev past 7500rpm without too much money and problems. The ka is a lot like the ej25 really.

I really don't think one is better then the other which is why I wouldn't swap a ka for an sr but I also wouldnt swap an sr for a ka. But I would throw them both in the trash for a big rb.

I know !!! Vh45det!!!

They're both weak and outdated. An RB25 is outdated but at least it isn't weak. Kind of like a 2JZ.

9/15/2011 8:22:46 PM

also, the problem with the SR isn't the rocker arms. It's the fact that Nissan Makes Some Junk. 4G63 have rocker arms you don't see them failing much on those motors.

as far as I'm concerned, the only thing an RB25 has going for it is 2 extra mains

whereas KA has a whole list of things going for it

Yep

i would bet it's still not even that reliable. unless it's built on some tall deck version of an LS motor or something that much bore and stroke in a small block is... beastly and scary. ( i think i'd rather have a 6 liter LS with twin turbos.

9/16/2011 9:15:28 AM

kind of like in that movie where they swapped a skyline drivetrain into an old school pony car

LOL

9/16/2011 9:24:58 AM

Yeah, I mean it doesn't really make any sense, lol. An F20C or F22C can make 400+ on stock internals when boosted. Why bother swapping in an SR?

9/16/2011 9:35:29 AM

yeah... i mean the sr is considered a rev happy motor... but compared to a FC20/22?? its lethargic. The only thing i could say is most boosted motors have boost control built into the EMS so knock sensors can limit boost as well as pull timing which helps the bottom end last a little longer.

But still i'd go with an fc over an SR anyway.

Quote :

"Please list"

cheap. with a little waiting, you'll see ppl selling whole engines for $100
easier to work on (and thus, more willing to boost the hell out of it )
cam on bucket, might be a plus depending on how you like adjusting lash
parts readily available
only 0.1L less
who cares about VVT in boost appications (RB25)
engine passes inspection
does fine unless you want 450+ whp every day imo

"who cares about VVT in boost appications (RB25)"

It's a nice thing to have, even if it's crude in these older applications. RB, VG, SR, all came with it and all had boosted versions. It helps spool the turbo. Of course the VR38 in the R35 has it as well, but they are continuously variable on both intake and exhaust. 90s Nissans just had it on the intake cam for a fixed # of degrees, like the early BMW VANOS system.

Also, KA has a distributor. yuck.

Best for max performance applications.

9/16/2011 10:39:16 AM

^^^The F20C/F22C is tuned pretty close to the edge from an NA point of view. But adding boost to the equation changes everything.

Quote :

Yeah the turbo kits for the F2xC that make that kind of power require an EMS.

Do you have any SAE papers on it Arghx ?


EMS to me is a bigger deal then a built motor but when compared to an SR swap... who cares neither will pass even a simple inspection.

9/16/2011 10:44:55 AM

Eh? How's that? I'm not aware of any S2000 turbo set ups that are not street legal.

This thread is about s13's and driftwhoring.

My stock baby rb20 on stock turbo and boost walked a s2k with exhaust over and over at the track.

9/16/2011 10:59:49 AM

^^^I wasnt talking about an SR. The KA will pass inspection, of course

When I think of "tuned to the ragged edge" I think of high comp and thin walls. Thus, I wouldn't think you could more than double the whp with some boost.

9/16/2011 11:43:32 AM

^both cars run about the same acceleration times, but the S2000 is very difficult to launch properly due to the lack of low end torque.

I've got a bunch of stuff on the SHO version which has been out for a while now. The F-150 version has better variable valve timing and different turbos. It's got a basic direct injection setup, pretty close to Hyundai and nothing fancy like newer VW/Porsche and BMW.

Quote :

"knock sensors afaik are disabled above midrange"

All depends on the filtering and whether it is a short term (immediate) knock control or a longer term knock control algorithm. It also depends on how many knock sensors the engine has and whether it has individual knock control for each cylinder or not. Knock control can be pretty complicated.

knock sensors on ka stop after 3000. Dont know about what SR does.

Try it if you like. Unplug knock sensor and drive car...

Motor has a forged bottom end. So that helps. It is a typical open deck honda design though. Youve spent too long in the nissan camp. They make some junk over there.
