Help me decide
Ok so heres my dilemna. LS or 2jz...both are power houses...both have a unlimited amount of upgrades...both are good. I cannot decide. My buddys pushin for LS..hes a chevy freak. Im pushin for 2j cause it seems easier (maybe im wrong?). It is my car so ultimately its my choice, but money aside ..i really cant choose. Any ideas? If it helps im lookin around 450-550 HP. I had a 350 HP subaru..not that it matters.

Tough call man... It depends on what you like to drive. I've driven LS swaps in 240's and RX7's and they're phenomenal. They have a lot of power, a wide power band, and the idle of a v8 at a stop light in an import has always been cool to me. However, personally, I went 2jzgte. Partially out of luck as I stumbled upon a great deal. I prefer the sound, look, and feel of the inline 6, and I always appreciate keeping a Toyota in a Toyota/Lexus. Money wise you'll probably spend about the same, but transmission choices in both cases can make costs differ (T56's are expensive these days, but so are R154's and especially V160's). My best advice, go drive an LS swapped car or even an F-body or something similar, and try to get your hands on a turbo 2JZ car to drive as well. I think both set ups would be very satisfying at the end of the day.
In that case, 2JZ is surely the easier route.
Still, if you're going to the trouble of a swap, I'd have a hard time passing on the much better base power, similar ceiling, better efficiency, and lighter weight of a LS.

For your power goals, both can do it. But I would say 2JZ. I'm the type of the "keep it in the family". Keep it Toyota. Make a 2JZ Powerhouse, single turbo
That being said, LS engines are phenomenal, easy to mod, tons of power and torquesssss.
I have an LS2 GTO and I love it.

GM LSx V8’s are excellent engines to swap into so many cars and that does include the 92-00 SC’s with kits made for this.
But I’d suggest swapping to a built 2JZ-GE, 2JZ-GTE or even a 1JZ-GTE VVT-i with an upgraded turbo if you like high revving.
Building an NA-T should be pretty straightforward though.
That’s the thing about these cars: yes, they’ll even take LS V8 swaps but when there is OEM/factory and aftermarket support for an already excellent engine (2JZ or any JZ) that will bolt right in and work with the existing electronics and various connections for everything throughout the car... why not just take advantage of that and make things easier if both engine systems are equally appealing, can both achieve mild to ridiculous horsepower and torque figures (with reliability!).
From the work required to the money required to make it happen to the factory bolt in nature of the JZ’s they win over the LS V8 for this car (IMO).
I like both engines personally (a 90-degree V8 is awesome and so is an inline-6) but it is easier and requires no custom work (other than your engine harness) to go JZ in that SC400.
And 450whp is very easy to achieve and you can do that with a stock relatively inexpensive JDM 2JZ-GTE ECU.
A 92-97 2JZ-GE short block with good bearings and good piston rings, an OEM 2JZ-GTE head gasket and your choice of a 92-97 2JZ-GE Non-VVT-i cylinder head or a 98-05 GE VVT-i head with a 2JZ-GTE ECU (VVT-i or Non-VVT-i) with a modern 58-60mm turbo on a Treadstone exhaust manifold and upgraded injectors of at least 550cc will do wonders.
And of course you can also swap in any full GTE engine if you wish. Usually you’ll need an SC/MKIV upper and lower oil pan, oil pickup, dipstick and oil level sensor to swap over.
