2jz vs 13b

>>14010699
One weighs 650 pounds out of the box and aftermarket parts can bring that down by ~2%. The other weighs 200 pounds out of the box and aftermarket parts can bring that down by ~50%. Both are capable of more power than you will ever need in anything but a purpose-built drag racer.

LS1>>14010716

2JZ is the better dyno queen, 13b is a better driver.

>>14010722
I would, but I'm an autistic weeb who wants a Japanese engine for my Japanese car

>>14010699
at a sensible power level like say 500whp use the JZ for a road car and the 13b for a track car

>>14010800
>500whp
>sensible power level
the absolute madman

>>14010722
Weighs 400 pounds, aftermarket parts can bring that down ~10%, and also capable of making more power than you could ever use. When you realize that the amount of power the engine can make is not the limiting factor of your car, the LS makes a lot less sense.

>>14010810
what a time to be alive eh?

13B is better because rotary engines are cooler. Better weigh distribution than any other form of engine, and can still make plenty of power. A 13B-REW with bigger turbos or single turbo and street ports can make over 500whp easy. Not near as much as a 2JZ but in a 2700lb Rx7 that is way more than you need.

>>14010716
13B-REW weighs around 400lbs stock, some say a little more or less. Converting to single turbo helps with the weight, around 25lbs. The block alone weighs under 200lbs, but with everything it gets heavy. Even at 400lbs it's still a 200lbs difference from a 2jz, and the V160 is much heavier than Mazdas transmission. With trans the 2JZ is somewhere over 700lbs, while the 13B-REW is still under 500lbs.

>>14010838
The 400 pound number is for the entire drivetrain. That includes 70 pounds of transmission, 20 pounds of powerplant frame, 20 pounds of exhaust, etc.

An LS bare block weighs double what a 13B bare block does. Why would you be considering attaching smog controls and cast iron manifolds to one engine but not the other?

>>14010869
That number does not include the entire drivetrain. It includes intake manifold, exhaust manifold, turbos, intercooler and maybe the radiator. Not the transmission.

I never mentioned the LS engine, I don't know what your point is. LS with transmission is way heavier than the 13B with transmission anyways.

>>14010869
I just went outside to confirm. I can pick up the 13B, but I can't even come close to lifting the 4g6.

>>14010934
Is everything on the transmission? Like both turbos, intercooler, all manifolds etc?

>>14010946
What? They're as you see them there on the stands. The 13B has a box below it resting on the stand with the alternator, intake manifold, clutch, and flywheel.

>>14010960
It's hard to see the engine in the picture. It also looks like some of it is aftermarket, and I only see one turbo and no intercooler. The 400lb number includes all of those things.

>>14010972
It's a $100 eBay manifold with a $100 eBay turbo. If that saves 200 lbs vs stock, c why would you not do it?

>>14010989
Again though, looking at the picture the engine still is missing things. I don't see an alternator, a/c pulley, intake manifold, the second turbo, intercooler and more. For the most part it is the bare block, which weighs under 200lbs.

>>14011026
Once again, you're not making a proper comparison. A 2JZ long block with no accessories weighs over 600 pounds.

>>14010699
C30A

>>14011261
A 2JZ weighs a little over 600lbs with everything on it, and 750lbs with the V160 trans. I'm not trying to compare how heavy a 2JZ is compared to a 13B, because I know the 2JZ weighs a whole fucking lot more.

>>14010699
FJ20

>>14011320
Well, this is well under 300 pounds with everything you see in the picture, plus everything listed in >>14010960. Keep in mind that this is on a steel engine stand, as well. Unfortunately I don't have a spring scale to give a precise number, but I can assure you it's significantly less than the 400 lb 4 banger next to it.

>>14011452
I'm sure it is under 300lbs with everything in the picture. The short block itself weighs like 150lbs, and the engine in the picture looks like it is mostly the shortblock with a turbo, flywheel, turbo manifold and some oil lines.

>>14011530
And that plus some plumbing is all it takes to run a car, so where's the problem?

An LS would be a better choice than a 2JZ unless you're going full dyno queen with insane amounts of boost...
