Keep The SR or Go KA-T?

[cc4usmc]

what about 1jz? is that still not legal? i have seen the other threads but i cant find the one that talked about California regs on swaps. i swore i saved it as a favorite bud i dunno what happend to it.

[ManoNegra]

^ I'm no expert but the 1jz you hear about being swapped into 240s are the jdm ones not the ones we got here hence they won't be smog legal. Forget the details. I'm sure Aaron can chime in.

[BigVinnie]

Heres my 2 cents and why.
If you are going KA-t build it right. Using cheap and affordable Altima/Xterra/frontier KA pistons drops the compression to 9.2:1, and these ringlands are thicker than the 240sx piston ring lands. This means higher boosting and more power, without the worry of frying rings.
You also live in cali, KA's are abundant at wrecking yards with parts (ecu's, heads, etc) gallore.
After market support is becoming better for the KA.
Hell obviously you were SR, now maybe it's time to get some low end torque youve never felt before. Torque band on the KA is much smoother and linear, thatsa great thing since you just have to shift a tad earlier than the SR.
Might as well let the V8 guy's feel your 2.4litre turbo charged WRATH....
Just my 2 cents....

i would never put in cheap parts. if i want ka-t it would be rebuilt using rebuild kit ams240 offers, but it would be the complete one here

i just found a s14 ka-t for sale in my area and i want it. no i have to see if i can get enough for my car since he doesn't want to trade...

LS-1 Will throw off the weight distribution HORRIBLY in the car.

BUT it is up to you.

Yeah it will throw it off HORRIBLY on the car. It weighs less than the KA and has the same length and sits lower in the engine bay. Man thats horrible.

Research your facts before you make uninformed comments.

There are several 1jz swaps here in the states. Garageworks iirc has done one. Pretty slick. Cheaper, stronger, more plentiful and more powerful in stock form than the RB25. Also has a higher power potential. Its a 2jz with a shorter stroke (same rods, same pistons, different crank, block deck height is just shorter)

hmmm...so is it a legal swap or not?

supposedly longblock + mani, flywheel, acc, etc weights look like this

sr ~ 330 lbs
ka ~ 370 lbs
ls ~ 390 lbs

QUOTE:
Weights:
KA with Auto, Cat and accessories = 596 lbs.
LS1 w/ T56, headers, and accessories = 468 lbs

That's right folks. The iron block four cylinder is 128 pounds heavier than the aluminum LS1!

[NemeGuero]

If you don't want to do a lot of work, don't get a KA-T.

I always thought its illegal to swap engines from another car make into another? Or is it legal as long as the engine is newer than the chassis and has all the smog equipment?

I know KA-T isn't legal either, but its easier to fix then an SR if a cop was to pop my hood and go . I'd rather not hear a bunch of "dont drive like an idiot and that wont have a reson to pull you over" etc. I just want to be prepared. Thanks Guys!

Tell the police you are fighting for this country and that you can do whatever the fuck you want.

that misleading

KA with auto = auto tranny still attached? vs. a LS1 with no trans? its probably more like 510 and 470.

still i agree the 'weight problem' is really people just making up excuses to hate the LS without any real info. a difference of 30 or 40 lbs is not a big deal

That's correct. as long as the motor is newer than the car and it passes legal smog, the BAR ref will pass it. RX-7 guys have had their v8's legalized already

dude... it says with T56. That's the tranny code.

KA-T for the win, even though I'm going for SR.

LIES!............

[fatalfury64]

what is the big deal with LS1? it ain't a genuine Nissan engine. would anyone call their 240 a Nissan anymore with an LS1 in it? Just my opinion.

[redsuns3838]

like u said, both are illegal, both with get u screwed if they pop ur hood, and neither will pass visual checks at a smog station...
if u get a ref ticket just go pay the fine. thres some threads on here about what to do if u get a ref ticket. read up on em if u can find em.

i wouldnt worry about getting ur hood popped. if a cop finds out ur in the marine corps i doubt hes gonna treat u like a little punk off the street, HOPEFULLY hed have more respect than that.

but its true if you dont drive crazy, theres not much to worry about.

Ref ticket and pay fine?
Thats only half of the problem. The other problem is having the car upto date on proper EPA/DOT regulations. If the car isn't fixed it can be impounded and sold at auction...... Some cars that are confiscated now in CALI are a manditory 30day impound if the officer feels that your car isn't safe for street driving.

Most of the local cops don't really care if your a Marine or not.

[fliprayzin240sx]

Most cops dont like marines unless theyre prior marines...

But anyways thats another point. Keep your out of state plates. Any plates is better than california plates thats for sure. Non-cali plates...no cali jurisdiction period. They can try to force you to pay fines or wut not but they cant do shiet to your car period.

who gives a shit if you can't call a 240 a 'Nissan.' It was still made by them, right?


This isn't a car to be a purist about. It's all about personal preference.

It has HUGE aftermarket; can make far more power than the SR or KA can; especially on pumpgas.

400whp and 400ft-lbs of torque with a HUGE powerband and tons of torque off the line is doable with a simple intake manifold, cam swap, and head porting. Drivability, gas mileage, responsiveness, etc... the list goes on. The swap is legal, provided the engine is swapped into an older car (not hard since most LS1s are 1998+)

The transmission won't shit a brick when you go to higher power levels either. The Tremec T56 is HUGE. Weighs double the KA tranny.

The 1jz isnt a legal swap either. It has no provisions for EGR, etc. It was never available in a USDM vehicle.

[Slo S14]

So let me get this straight, a drifter uses an Ls1 so all of the sudden its the new fad?

Well not to argue but to some people it is about being a purist. As for me I've owned nothing but Nissans. Owned a Datsun 510, 240sx, hardbody, and then a 2004 frontier. Some people just like the nestalgia and respect that comes with the badges and logo's that comes with the vehicle, and then again there are those that don't give a fuck....
Half the people that buy Nissans don't even know that they built the kamikazi fighter jets that fought against us in world war 2.... So to some they don't know enough about where or who our own enemies were.
I'm a purist because I respect the technology that comes with Nissan. I respect chevy because they build great powerful trucks at an affordable price, thats about it....

[EchoOfSilence]

Actually, it was Mitsubishi that built the Zeros.

Anyway... don't get me wrong; I like what Nissan used to be, and Nissan later may be great. But I do believe there are better manufacturers out there. I say that this car isn't one to be a purist about because it doesn't have as extensive of a history as other cars do (although it does have some race history). Instead, most of its background is based around its use in a sport where anything goes.

Give me a 510, a 240z, a Skyline, an M3, a Porsche..... etc. Those are better candidates, in my opinion, to be a purist about (if you'd like).

However we're going off on another tangent.


I like both motors, however I've never been in a nicely running tuned KA-T (Evan )

What huge power band, the rev and redline is about as consistent as the KA's on boost. It will drop out before 7000RPM. Now if you talk about the z06 vette Ls7 now you have an engine that far surpasses the power band of the sr on any level with a higher peaking redline as well. LS1 is small potatoes as far as rev and redline is concerned.
