Turbocharged KA24DE vs SR20DET Swap

[Onizuka]

not having to be with out a car for a few days, while i wait for a water pump to be air mailed from japan (long story).

you have watched too much F&F :rolleyes

there are literally dozens of shops in the US that stock OEM replacement parts for the SR20, or if you prefered you can go with a JUN upgraded water pump. Even if you need a whole new block that is easily attainable now days (although more expensive than a KA one).

WHO EVER BELIVES THAT A SWAP/TURBO KIT IS ALWAYS CHEAPER THAN THE OTHER ALTERNATIVE, PLEASE COME OVER HERE SO I CAN BEAT YOU WITH THE REALITY STICK!

Anybody who is misguided enough to think that ANY turbo application is going to be "cheap" is not getting the whole picture. People who do KA-T's "cheap" know what the hell they are doing and have the skills in fabrication and kit assembly that 99.7% of nico members dont have. You can do a SR swap "cheap" if you want to, but its not worth the risk in my opinion.

this is the most retarted argument ever, the KA-T guys that dont know much about the SR are arguing for the KA, and the SR20 people who dont know much about the KA-T are arguing for the SR20. THEY ARE BOTH GOOD MOTORS, can we just leave it at that?

is someone finally making sense on this post?:eek:

Actually, its the fact that they know what they need to about both, and have chosen the one that will work best for them. I was gung-ho SR for a couple years until I started doing research. To me, empirical evidence proves itself, and the numbers show that the KA is more efficient at lower boost. I've ridden in a SR powered 240 and a KA-T powered one, both around 220-230 hp, the KA-T was much faster...it was rediculous.

but..... isn't there a ton of posts with this same topic?

[Onizuka]

Yes there are HUNDREDS of threads with the same subject matter in them

I've ridden in a SR powered 240 and a KA-T powered one, both around 220-230 hp, the KA-T was much faster...it was rediculous.

If the KA-T was faster, it was putting down more horsepower, because horsepower is torque applied over time. There is a recent thread in the CA18 section where a guy has both a KA-T and CA18DET, and the CA is faster. Just because you rode in 2 cars mildy tuned doesnt make one better than the other.

[SHiFT]

Then maybe they weren't the same hp, but relatively the same amount of money was spent. Thats what it mostly comes down to anyway - money/performance ratio. All I'm saying is that for a sub-300hp 240, I'd say the KA-T is best answer. I just tried to provide some help above to clear up some misconceptions because they are scattered throughout this thread. And BTW, the KA-T (9psi, stock internals, 370 injectors, FMIC) beat 3 SRs around here in orlando, I'm not just talking out of my ***. If you ride in both you will see what I'm talking about, very different engines that perform totally different. I just like the KA better, but to each his own.

[Jookmasta]

hey shift, these people that you know that have a KA-T, how much did they spend in total? just questioning out of curiosity

[SHiFT]

I believe the total for the KA-T was $3,500~. He bought all new parts plus the Greddy V FMIC costs like $800 by itself. Don't remember specifically what he did for fuel except that I remember he used the stock fuel pump still for 9psi, worked fine. Maybe a JWT ecu was in there somewhere adding to the cost, but don't remember for sure. Sorry I can't be more specific.

[NS180]

i think that we should just all stop arguing over what motor is better. the bottom line is both are nissan motors so they kick ***.

for the record the ka transmission except for the bell housing are exactly identical the gears are the same i have een usine a ka transmission for about mounths now and it puls hard tops out the same speed and i get the same times in the 1/4. and when you have bothe of them pulled apart you can see wha i mean. sorry for the confusion.

i own the sr but i belive its just a matter of what you want if you dont buy into this jdm hype then most likely you got a grudge against the sr. i guess the only real advatage is the wide variety of japanese produts available for the sr.

[elusive240]

I've got a friend in Japan with an S14 Silvia. Obviously he's got the black top SR20, and his engine is pushing around 420hp to the wheels. He's running 12.9 in the 1/4, and he has absolutely no complaints about the engine. I haven't heard of to many KA's with over 400 horse.

[theronin]

^ you will be. just give the kat some time.

[89240sx]

I've heard of a few atleast.

[w1ngzer0]

lets see... japan vs usa..... im sure they have a ton more SR20 modified in japan the KA in the usa.

yet more pointless posts MODS IF YOU CAN SEE THIS POST PLEASE DELETED THIS DAMNED TOPIC

BTw im going to start posting pointless posts like cheese,ice cream, oil, smiles whatever to get this topic deleted

to much F&F lol

no try an rb25 in a 95 240, and having to wait 4 days in the middle of no where kansas, for a damn water pump, sorry, but its easier to go to napa, and get a water pump than it is for a SR RB CA< ect, thats my point.

its just the point that drivability is important to ppl likem, so that if i have to drive cross country with the only car i own, then i want ot be able to get parts for it if it breaks down, and cars dont break down infront of a shop that carries parts for your cars JDM motor, its not as easy, but yet its not impossible either, to each his own

[Nathan]

12.9's with 420hp is rather slow.

[jdmfreak]

I was thinkin the same thing.

[jdmfreak]

I see people with less hp hittin those #s

[w1ngzer0]

its called tq people...:rolleyes op forgot the other main factors. driver and tires and suspention.

btw i like cheese with ice cream the cheese compliments the ice cream well with motor oil then i feed that to the sharks which fart dolla dolla bills yah. Lets see then i find a random engine let it sink to drain the pool of cool aid.

[egan]

**** it, im going rotary

[w1ngzer0]

at least its legal

[Jookmasta]

hey shift, whose 240 is that with the 400 hp with the KA-T and do you have his email address?

[SHiFT]

I don't have his email, his name is Jay I think. He builds up 240s then sells them. I met him last weds here at a car meet. He sold that blue S14 btw. Now he's got a real nice looking light green S13 with a SR and full JDM front end conversion. Real nice, he'll be selling that one too. Someone told me he's made 6 SR powered 240s and still thinks the KA is the best one he's had. His SR in there now is a freakin beast though. Sorry I can't be more help.

[Hellion240sx]

is he the one with that clip where he raced an eclipse, at the begin of vid it said jay's run, hit a 12.57 @118.21"bring me a higher love ohoh"

[Jookmasta]

well if you ever get in contact with him again or get his contact info, im EXTREMELY interested in going the KA-T way and im sure he could help answer some of the questions i have.

[Nebraska240sx]

http://www.nissaninfiniticlub....shtml 412 hp and lik 420 tq i belive runs high 11's, thats a KA-T

[Nebraska240sx]

oops bad link hold up

[Nebraska240sx]

http://www.nissaninfiniticlub....shtmlthat was the link for it before things changed, mabey an admin or some one can find it, but it is true a 400+hp/tq KAT running high 11's in the video linked on there, so its not a spoof. it really has happened. (im now depressed that that link dont work, that was one of my fav 240's) some one find it plz

[Nebraska240sx]

and his name was jay

[SHiFT]

Well, I talked to Jay last night at an orlando meet to ask him about stuff relating to his KA-T. He builds cars up and then sells them. He's done 3-4 SR powered ones and one KA-T. I asked which one he liked best and he told me the KA-T. He ran 30 lbs of boost with his setup to make his 412 hp/412 tq. Said it was a freakin beast. The SR's run smoother but the power of the KA is much stronger. The only problem he had was blowing headgaskets, 3 of them total I think. He spent $6000-7000 total but he said at the time pistons and rods were $1800 by themselves, now they're much cheaper. Hope this clears things up a bit about his 11.92 1/4 run.
