That'd be a completely street legal swap in california wouldn't it? (only reason I wouldn't go with any of the RB or SR engines... cuz' the chp been crackin down lately on any "illegal" modifications poppin hoods and stuff )

Yeah, the US model was rated at that, but we're talking Japanese here aren't we? The 2JZ Half-cut doesn't cost $2000 either...and I'd need a complete half cut in order to complete a swap.

My shop is in El Mirage, AZ. To do the complete running swap of a 2JZ into a 90 240SX would take me a couple of weeks of working on it to get all of the bugs worked out. Since the 2JZ is a US engine, you would be able to pass board in California if you registered the car as a Supra...since in Cali it don't matter who makes the car, it matters who's engine is in it... It's not a cheap swap in any means though.

for the price and over all its rb25det.....

[NightXCZ77]

RB25DET is an awesome engine reguardless...and yes, in this car it is much better off and much cheaper...

[klohiq]

the 11k price quote was taken from one of the only sites doing the swap on the internet...

I don't care what you will charge night...and it was a USDM 2jz...As for cost of the engine...I believe I got that from the swap site too...

And JDM engines aren't limited to 280hp...there has been so much debate that I'm sure many are above that little agreement or law or whatever you want to call it...

You could come in here telling me you'll do an rb25 swap for 5 dollars...I don't care how much you charge, that price quote isn't changing.

[musicsurfman]

The 280hp Agreement, Is Just That, The Manufactures Agreed To Keep All Cars Under 280hp.... So They All Rate The Cars That Way But The Engines Produce More. Like The Rb26dett Rated At 280hp, But Produces Almost 322hp.

[NightXCZ77]

Well, here's my price quote for the 2JZ Swap then....$6k for the labor, wiring, mounts and driveshaft....How's them apples? There's the new standing quote...that other company can battle it out if they want to. Anyone willing to pay $11,000 for labor on a swap i an idiot unless you're getting an AWD Conversion RB30DETT or some weird ass shit like that.

The gentlemen's agreement is 280hp...true, most vehicles (the GT-R) go over that agreement in some respect...as far as AWD HP, the GT-R reaches about 280-290 all 4 wheels....and about 320 if you go RW with it.

but than again why go through all that trouble on toyota when you have a NISSAN id say go with the rb25det its less expensive easier to mod and its nissan power

[coloRB240]

hold on if you are willing to spend that much go rb26dett

Until you've driven and handled the car...leave heresay to people with less respect than your 1600 posts.

Of course you think it handles better than with a KA. You paid for all this crap, so you will ultimately be biased towards it.

With that said, what did it take to acheive 52/48 weight distribution? Trunk mounted battery? How much does the car weigh?

I drive a car with 50/50 weight distribution(BMW) and I wouldnt trade it for anything else(i.e I'd rather have an SR with 50/50 weight distribution and 2 less cylinders), but I am interested in how you achieved this.

the rb is easier to mod than the 2jz motor...
riiiight...

this is a really funny thread... b/c it's all opinion, and little fact...

[NightXCZ77]

I'm not biased. I own 4 240's and invest a lot of money into each of them. The RB car handles better no doubt...

52/48 is installing the RB...plain and simple. That's my weight distribution which comes out to about 50/50 with me in the car. It's so funny how people with no up front knowledge or dealings with these engines think they are an authority. My car weighs a little over 2800 pounds...it's a LE.

[flylwsi]

the rb car handles better.
so you've driven a supra power 240?
or the sr20 powered 240?
or a ca18 power car?
and did you drive the rb25, rb26, or?

it's hard to claim you're not biased if you not driven all the options...

in any case, i'm not going to argue with you on it, but this thread is 90% opinion with a slight amount of fact...

I didn't claim to drive a Supra Powered 240...being that there are probably 2 or 3 in the states and there would be virtually no reason for me to do the swap when the RB platform is easily accessible.

Now...I have driven KA cars, SR cars, and RB cars....CA's - No, however, of my experiences, the RB handles better. I am not biased on my opinion, I judge handling and cornering on each of the vehicles when I take them out and the RB holds it's own. The KA is second and the SR is about the same...the difference between those two motors is virtually un-noticeable when it comes to handling since there is such a minor difference in weight, tranny size, and distribution. The RB transmission weighs quite a bit more than the KA or SR, thus, that weight is more central to the vehicle. The RB motor in itself weighs about 100 pounds more than the KA. If you were to relocate your battery you'd notice maybe a 50 pound difference. For people like me that also go to a lighter driveshaft, we lose about 15-20 pounds going through the center of the vehicle. Everything thing you do affects weight...whether you can feel the difference of moving a battery or not is up to you. When I was 52/48, I had my battery in front.

Weight has a very direct affect on handling, generaly less is more.
By adding weight to a car you may alter things like its responiveness, willingness to turn in etc, but you are also giving the suspension and tyres a lot more work to do. The simple result will be a decrease in the ablity of both to maintian grip when cornering. Modifications will be required to allow for the extra weight, which of course should produce (if done properly) a car that handles better than it did when stock. By any chance did you also modify the suspension and change the stock tyres size?

And I am also curious about how you managed to take a front heavy car, add more weight to front and middle of the car, and even out its weight distribution. You must have removed weight from the front of the car somewhere, or added weight to the back end as well. Or you need to go and re-weigh you car and check you numbers.

Since a normal 12v automotive battery weighs between 35 and 50 pounds, it isn't a 50 pound difference...it's about a 70-100 pound difference...I'm wondering how well you can be trusted with doing a swap when you don't even understand physics.

BTW does that 6k quote include you taking the person's money or not ...I'm just kidding...I'm sure you're the greatest mechanic ever...

I agree with Dorikin that you would have a biased opinion since you are the one trying to get people to pay you and to buy engines off of you. You also spent all the money and time dropping one in your own car. A few percentages shouldn't affect the car much since just changing small things like driver weight and rim choice affects the car greatly too...

Can't we just agree that all these engines are way better than domestics and leave it at that. I personally like the KA-T, CA, and RB25...but I definitely don't hate any of the other numerous fantastic engines that Japan has to offer (20b, 2jz, rb26, etc)
