Piggyback Recommendation

how did you correlate target power number to target boost level? It doesn't work like that. Also, if you're not the one with the fab skills, the dollar amount involved to meet your goals with this project will double that of a 1jz swap which you can get running without really fabricating much of anything, a monkey can pretty much bolt together a Jz swap in a driveway. Either way, the cost of reliable 500whp is steep and if you're already looking at eBay parts that means you can't really afford it. That statement isn't made trying to be an *******, it's made because it's true. Go that route if you want, just know from doing this kind of stuff over the last few years with two 400whp daily cars in the stable for those said few years that cheating out leads to more money in the long run.
Another thing I guarantee you didn't think about is diff/subframe bushings, diff condition (bet it has a leak somewhere), and front suspension condition (bushings/balljoints/rack bushings). Most likely that stuff is shot or close to it. And stock struts. 400whp on high mileage 25 year old suspension is sketchy and dangerous, especially for someone that isn't seasoned to driving a vehicle with that much power.
Oh, and then there's your open diff. So you're basically gonna roast one tire at all times and get beat by stuff that has half the power and can hook. have $1200 for an lsd in that budget? You want reliable, better come with $7k minimum with you doing every bit of the work. Or spend like $3500 and start looking for a daily driver if you don't already have one that isn't the lexus in question here

I thought about a engine swap but it would cost close to the same as boosting the 1UZ

Durvelle27,
I can appreciate your confidence and your adventurous spirit and I'm all for building the 1UZ. I think that if you are doing it because you love this motor and prefer it for your build then there couldn't be a better choice for you.
If you are doing it because it will cost you the same or less money you might want to re think that.
I put together a few "buy" lists for boosting my 400. Every route was way too expensive for me. I chose an NA/T setup for my 300, and although way over budget, it's considerably less than the 400 was going to be.
There are several guys that have done turbo 1UZ on the forums, they ALL say that it was waaaaaaaaay more expensive than a 1 or 2J swap.
Do it if you love it like that though......
Best of luck either way.
Are you making a plan up for yourself, or following a successful build you found?

I have to concur with Vrank and Studiogeek about the costs involved in going the 1uz route if you want to do it the right way.
I´ve been collecting parts for supercharging my sc400 for a while, but has that project on hold right now, in favour of the cheaper and easier 1jz route for my sc300. But some day .
Durvelle27, Don´t give up! Take your time. If you´re willing to pay the price, I´m sure it will be worth it!
I think you should ad headers to your wish list.
I can recommend Rush headers from down under. Great sound even if you stay NA. Talk to Neil at rushimports in Sydney. He´s a great guy.
If Money is no object:
Here´s a standalone ecu that´s plug and play for the Soarer V8(should work for the sc400). Takes care of the transmission as well.

its not great or perfect but you can make it work, at least the stock trans on the lexus has a line to the throttle body for line pressure, so on those transmissions its not even handled by the ecu. on a 2jzgte automatic, that is handled by the ecu.
basically if you set the shift points conservative it should hold up to a little boost, but just manual swap it there are like a half dozen manual swap options now for the sc400.

You basically have to drive the car like a manual car to get it to shift gears..
So you literally have to let off the gas at 6-7k rpm then it will shift that gear, that's in every gear..
So until they fix all those issues on the V2 , I wouldn't waste my money on it.
Same goes with a TT supra at my friend shop, it doing the same thing.. Still waiting on the fix.

yes, I am using it on my 1JZ. It is probably the most powerful piggyback that you can get, and the closest to stand alone. You can make timing adjustments, fuel adjustments, adjustments relative to coolant temp, and so much more. I don't know much about using it on the 1UZ, but have a look at their website in the downloads section. They have basemaps for all different applications: RB's, 3SGTE's, 7M's, SR20's, VG30DETT, etc. I don't see why it wouldn't work on 1UZ. Have a look at the spec's on their website and join the forum and ask if it would work on 1UZ. The forum is pretty active there with MAP-ECU Man getting back to all with answers.
The only thing is that you will have to learn to tune yourself most likely. Not many shops know much about it. But it is pretty straight forward.
