Default 2000 GS300 w/ 2jz-ge

Alright I've got questions. Too many to ask right now but I'm not too much of a car guy, but I'm learning. I need help with building under the hood of my GS300. As in, what should I upgrade first? Best brands, dual or single turbo, etc. if you wanna see my car, check out my profile pic. I know yall will help, so I'm reaching out. Thanks.

Default Building my GE is only option

I'm not looking for the fastest car in my city, just good enough to compete with my friends and etc. i know a GE can become a nice street car sleeper. That's my main goal.

First, welcome to the forum.
Second, Save some $$$ and do it right. Because the 2JZ is not much to modify the way that are you want right now. Sorry for tell you that. But at the end, is better to do the 2JZ GTE swap. So again, save some $$$ and do it right. It is you main goal, right?

Using all the original factory turbo parts solves many expenses and choices at once. The JDM gives about 280 hp (50 less than a US Supra engine with very similar parts), is already substantially faster than your GE, and can easily be over 400 using bolt-on parts without touching the engine itself.
Adding a turbo to a GE engine means you have no electronics to control mixture, boost, or spark, you have to build an entire exhaust system, and someone has to design and install it. A shop may charge you $10,000 to do the whole thing (drive it in, drive it out).
All factory TT engines (in US it's only the Supra, in Japan this includes the Aristo and Soarer) came with a special transmission: either the very expensive Getrag 6-speed, or the very cheap (comes with the JDM engine) but very special 5 solenoid, larger bellhousing A341E. These are not used with any NA motor, and the NA transmissions don't do well with high power levels unless you baby them (and who wants to do that).
Even if you decide to make a big engine (700 is easier than you think), the GTE core is a better basis than yours because you can profit from the huge amount of data and products developed specifically for this engine.

Please feel free to ask more specific questions, let us know what you're thinking.
I think I've decided to just swap to a GTE because I've realized the price of just building a normal GE. What exactly does the GTE come stock with beside the turbo? Not much of a car guy, but I'm learning. I was asked to just buy a whole new car that had the GTE already in it, but that seems like a hassle trying to find it relatively close to where I live, plus I felt it would probably have more miles and also the price. And another concern of buying a whole new GS300 with a GTE is the probability of the previous owner not taking care of it.

OP,

If you lived in Florida, I have a quote for the swap that inclu. Engine, Trans, LSD Diff., Wires Harness, Full Line, E-shifter and cluster working correctly for $6,500.00 But again, good luck with your swap.

The GTE engine has better internals (iirc the GE VVTi in the GS has weaker rods and crankshaft).
