Just to give an example of what I'm looking at
First to come for my project is an r154 manual conversion swap. Anything manual for the 1uz will require fabrication because of the flywheel and adapter plates from tranny to bellhousing. I researched and researched, but upon all of this, I figured I might as well just go for a kit so that I don't have to find prices for a 1square foot by 35 mm thick aluminum block, even though I already purchased it. Have it machined and a flywheel. If I go with a kit, it will kinda be an off the shelf item through the maker of the kit.
Next is turbo setup. This one varies for everybody, but my application I will go twin turbo with Garrett t25 for the time being. For this, I need to decide how I want to fab my exhaust piping, intercooler and exhaust.
Then, since I want to run at 11-13 psi on these turbos, I need standalone. This is where I'm really hung up on.
A really good site for the 1uz is lextreme.com.
I think that overall most information that people gave you in this thread is pretty good, but it all comes down to what you want and the obstacles you're willing to tackle. For me, since I've never done a v8, and just feeling the power of the stock motor and my plans for the project, the end result will be priceless. Grinning from ear to ear hearing my custom built exhaust rumbling.But that's what motivates me.

Yeah that's understandable. This swap will take place alot later down the road and I will have more equipment to do this and more people to help me out if needed. And with the 1JZ, since the stock inline 6 that comes in the SC has dual exhaust, is there a way to get dual exhaust for the 1j? And like what I asked above, what are good places to look for 1j's and the aftermarket parts?

1uz is expensive to mod. 1jz are good but finding parts is a little harder why not na-t the 2jz trust me the ge can make lots of power with a good tune the only thing you would worry about is if your tranny can hold that much. Look in clubna-t.com lots of impressive builds and number on 2jz-ge's.

You'll just need to upgrade the tranny.
Ls400/sc400 motors are cheap. Since I already have the early 1uz motor which is the stronger rod version , then that does also help me decide to stay 1uz vs 2j/1j
Like the above guy said, if you're not mechanically inclined, this project will be extremely difficult.
Also, another example, for the r154 swap, besides all the crap mentioned above that is required, I will also need to do a shifter extension. This I will handle myself. So cut, measure, and weld is also required for this
Goodluck

Chaser motors aren't as much of a plug and play as the soarer 1j. It's not a huge deal but you'd have to buy a different oil pan and wiring is more of a hassle. Honestly, I'm probably not the right guy to ask about chaser motors as I haven't worked with one. I'm sure someone else can chime in on this though.
Like I was saying in your intro thread, do some searching, after a while people aren't going to be so nice to try and help you make decisions about your own car with subjects that have come up time and time again

By easier to manage I mean that upgrades are easily accessible for a 1j, and as you're hearing from everyone else, 1uz upgrades are not. If you really wanted to go with the v8, you might as well go get an sc400 and save the hassle.

I think the reason why he asked that question is to tell if you're a person who can fix/ handle your own problems (pc) or buy a mac like all those people who can't fix their own viruses and such and get a mac. just like in this situation where you would pick 1uz over 1jz. If you're challenged go 1uz, if you're a mac go 1jz. IDK just a guess LOL.

To be honest with you need alot of reading, R154 swap in the 1UZ is not cheap so before you start tearing stuff apart or start spending money you must know what you are getting yourself into.The conversion kit is not cheap make sure you wanna spend that kind of money and your car will still be slow .
If you like the V8 and ready for challenges go with the V8 and twin or Single Turbo
If you on a budget and want something with decent power something little quicker and not breaking the bank just 300rwhp-350rwhp just do 1jzgte with R154 and enjoy your car this swap is almost PNP in your SC400.
Again just search on this SC section and you will see all the other that had the same idea.
hell there is 1jz vs 2jz vs na-t vs 1uz on here somewhere it full of info and i am sure that will help you make up your mind.

if i was the OP i'd just get a 1jz.... swapping in a 1uz seems pointless unless its vvti and manual otherwise your just making a sc400 and they are not fast haha
we all know he's not gonna turbo the 1uz.... no point sticking up for the 1uz and what it can do because its not gonna get done.
go 1jz or na-t..... or spend a bit more and go 2jz-gte

Just write down the pros and cons of each. How much are you willing to spend? How far do you think you're car can go in mods in the future? Are you challenged or not? If you want a challenge by all means go 1uz
1uz-hard to mod, expensive, but great potential
1jz- easy to mod, variety of aftermarket support, doesn't cost as much as 1uz
in my opinion.. I think you shud just go na-t the ge can make plenty power for the price. If you want above and beyond go 1uz. But why go 1uz when you can just save yourself the trouble and buy an sc400 and manual swap it. It just doesn't make much sense getting an sc300 only to swap for 1uz. So right now the options you can do is go 1jz, na-t, or 2jz-gte if you had the money.
