My opinion doesn't matter here. If anyone is the fan boy and resorting to petty attacks, it's you.


I'll agree that parts for the LS motors are uber cheap (heads, cam, headers, stroker kits, etc etc) but I tend to compare relatively stock motors. The LS series is the SBC of our time and has a downright massive aftermarket (shit, why even bother buying an engine when you could buy all the parts to build whatever you want). Pulling a truck motor just doesn't sound cost effective because of it.


You guys seem to think I dislike the LS motor, the facts are the opposite. It's a fantastic platform for reliable, streetable power. My "disposable income project" I have in mind is a C3 vette with aftermarket suspension, LS motor, and a T56. Now if only people would stop thinking their POS C3 is worth ludicrous money...


I have about ten years experience with Supras in general, and had a lot of friends with 4th gen F-bodies, of which 2 required engine replacements under warranty for oil starvation/piston slap. I'll admit I don't know the full ins and outs of the swap in this car, but I doubt anyone here has done both swaps anyway.


Never done standing mile stuff (I really should go out there as I'm relatively close, but anyway...), but I'm sure we've all seen Titan's Supra in action :) I don't think they've ever put that thing on the dyno publicly, at least that I can remember.


Just seems to be the general trend in this thread... I think most people can agree that both motors are absolute monsters that routinely punch well above their weight in the car world.


Because it simply does because of engine design. Much like a V6 is inherently a crap design from any standpoint besides packaging...


That's your opinion.


Which is easily handled with a forged crank (the 2JZ has one stock) and an appropriately sized harmonic dampener. This isn't an RB motor...


While it would be technically stronger, it doesn't have much of an advantage balance wise.


Agreed (just wish we saw more flat-plane V8s here)


Going to depend a lot on the placement of the turbo IMHO as a huge lump of cast iron could sway things. Not to mention the weight of the intercooler and piping (though this is really the same for any boosted motor).


I'm sure it pisses them off when people swap WRX motors into the 914 so it can possibly outrun the ugly...


Another common reason people go with a single modern BB turbo on the 2JZ and 13B. Well, of course it makes more power and it's cheaper than twins, but it's also a hell of a lot lighter trimming all the cast iron off the side of the motor. Typical of all headers though...



Most people aren't going to be able to tell the difference in weight balance... but they will tell the difference in the torque and overall drivability of the car. Trying to find the magazine article where they pitted an LS swapped FD vs a modified rotary FD (they were about equal when it comes to HP and overall setup) and how the general consensus was that the LS swap didn't hurt the car at all.


If we could get anywhere near that success in this platform it would be great.

My scale doesnt go that far so I ordered a 500lb scale today. I figured I could use it for shipping things as well. It should be in next week then ill drop her on there take a few pics and post. :cool:

Why aren't there more LSx powered 240sx/Silvias, RX7s, S2000s, FRS/BRZ/GT86s, etc. competing & winning in time attack? I can only guess that the torquey power delivery causes traction problems if the weight balance isn't thrown off... I mean, they do compete and do well in drifting and drag racing, but where are they in circuit racing if they are so dominant and without weakness?

Here let me refresh your memory about who started the petty attacks...

Not to mention your "hear say" stories from "friends" is all exgaggerrated rubbish.
There were a few cases of piston slap and oil use issues on early LS2 motors which was corrected under warranty.. These are facts, unlike your petty BS stories.

What do you expect when you put an engine with that kind of power in a chassis without enough mechanical grip to handle the TQ?
That's why they come from the factory with small displacement low TQ motors.. To match the chassis capabilities.. The engine isn't the problem here.. It's getting the power to the ground..

Best thing about LS's: once you blow em up, you can go find another bare block for stupid cheap.

Here's my thing. I love LSx engines... cheap, reliable, and great power. Will handle what the average Joe will ever throw at it forever. If I'm building a competition car and engine choices are between 2jz and a newer LS... Blown LS all day.

However reason I went 2jz vs LS in my FRS is because I can still make upwards of 800whp on stock internals, all day, reliably(I.e. I've been 840+ whp on a stock head/bottom end 2jz for 110,000 miles in the past)... Little more expensive(for most) but a 2jz is still unbelievably capable and stout as long as you're not sucking it up with a shitty tuner (all engines).

Also... LS swapping my car makes me feel like a basic bitch. Lol... And I'm not dealing with a t56

Made me chuckle... equates LS swap to "basic bitch."

What don't you like about T56 transmission and in your experience what gives the supra transmission the edge? (I don't know which transmission is on the stock 2jz)

That's kinda my whole point. I'm not saying they aren't great engines. I'm saying maybe they are not the best choice of engine to put in every single chassis that has ever existed for every motorsport in the world, like some seem to believe.

I am also curious as to the problem with the t56 and now the t6060.

As for if it's the best that is the choice of the owner. There are also Ford 5.0 swap kits straight from Ford.

The LS series is user friendly, easy to work with, lighter than most alternatives that can get in its power range and can be found as early as walking into a junk yard if you are in a tight spot.

As for the similar rotary vs LS swap the differences came to light just 10k after that if that long when the rotary went down hill and the LS kept going. Then you had the fun of trying to rebuild the rotary when even Mazda stopped making the housings for them and the coating from the factory to make them last longer is not easy for others to replicate so most rebuilds last half as long. None of that sounds ideal when you think about any swap long term. This is rapidly important if you plan to really use that vehicle for constant hard tasks.

Now some situations will call for a different approach, a 4 cyl or v6 might be the better choice for class options, space constants or any other number of reasons.

However there is a clear reason the LS series has been so popular for swaps and that's because in almost every swap it's light, reliable, powerful and it adds value. Many swaps can't say all that together.

Now if I made any small mistakes it's most likely auto correct as I'm on my phone so I apologize.

Size.

And 6 speed Supra trans is a v160. In which I'm not using, I have a 5 speed good for 850+ ft lbs at a bargin

There is a billet aluminum block for the 2J that weights only a 85lbs compared to the oem 225lbs iron block.

Agreed...! I don't want the "funny car" experience with the FRS.
I enjoy keeping my foot in it, and the relatively long run thru the rpm range.. The chassis and feedback makes it feel faster than it really is..
I also don't think the unibody on this car can handle the large amounts of tq without some detrimental affects over time..
I like this car as it is.. I'm one of the few who think it's quick enough right out of the box.. But I also enjoyed the muscle car years and Vettes for the past 15 years.. So I can understand why some want more.. But it really is a fun ride as it is

this isnt a debate about stock power vs an ls swap. its about forced induction vs displacement.

There are tons of aftermarket for both of them. Like my stage 2 Tick T56 that will take pretty much anything I through unless I break 1000hp which as much as I would like to say I will I'm not going to. Or stroker kits for less than the cost of an LS2. The aftermarket's are great compared to others mainly because these motors have proven themselves for years.

I bought that trans with the tick clutch master I will be using to replace the stock FRS clutch master. I also got a spec stage 3+, light weight flywheel, brand new gm slave with speed bleeder basically the only thing I didn't get was the drive shaft but u get that to. It may not be as great a deal as yours but I was happy with it.
