"whatever" swaped st205, which motor would worthy replace a 3sgte? Options

OK! I know it's not a forum friendly discussion but it's really common on other cars (rwd mostly)
you see sr rb 2jz and ls , bmw and mercedes v8 and v10s powered cars a lot these days.
Of course you can make that power of a 3s but it's not the best motor around.
Which swap would you do if you wanted big hp numbers and reliability for an AWD st205?
I've seen some v6 but they are fwd , and also a 4g (evo) swapped here in Greece.

I would like to hear some opinions and not the typical "stick with your 3s".

1uz wont fit with any traverse awd layout on the 6gc. The oil pan would hit the ground without a dry sump system and the front of the block (without any pulleys or accessories) would be 6 inches past the inside frame rail, meaning after cutting the front of the car apart to make it fit your passengerside tire would rub the block when making left turns.

You could potentially start cutting up the car and weld a longitudinally mounted 1uz in, with a 4x4 transfer case and a solid front axle. I dont think IFS would be possible, you need an axle with a differential and the differential has to be offset to match the driveshaft from the transfer case. Lastly you will need a custom rack and pinion or worm gear steering setup and a fully custom front suspension.

If you want a 4liter, awd celica, the only practical way its gonna happen is swapping an 2grfe in with a 1gr crankshaft. It would eat 1uz's for breakfast.

An V8 awd celica is impossible, a 4wd celica is possible but not at all feasible. Easiest way would be to weld the celica body onto an existing 4x4 chassis

Thanks Special Edy!
A quick search showed that the 2grfe is a more common platform and can make some serious power.
Accordingly to you and what I understand, the 2gr-fe produces 266-280 hp as a 3.5l engine.
If the 1gr rankshaft is interchangeable then the extra half liter will push the power to more than 300 na hp and some tons of torque. all these are measured with just 87 octane fuel!!!
Plus the awd capabilty and comparative low weight due to the aluminium block.
So, lets say

scenario 1 : a light turbo set up
How much boost could the stock motor - fuel system - ecu - etc could handle and support?
What power should be expected from this?

Senario 2 : a built engine to support more boost without excessive modifications but retain drivability characteristics.
factory forged rods ( If I'm not wrong )
a set of forged pistons,
arp studs
a set of cometic gasket
upgrated(?) fuel system
a piggy back ecu? (is there something that support 6 cylinder engines? or a stand alone unit is nessecary?)
a stronger clutch
and what short of power do you think should be expected from such a set up?

It's a hard motor to source tho. What would be the most common cars that came with?

1mz block 3mz heads
Forged internals
Add boost till happy

If you stay awd that is

Other way around. 3MZ block with 1MZ heads. you would need serious mods to the 3MZ heads to put them on a 1MZ block.

That's what I meant. Brain fart sorry.
I would love to see a and v6 6gen turbo or not

Me too.
This thread was not meant to offend the 3s potential.
I just want to make something different and maybe better.
v6 and v8 motors are awesome!!!

Could you give some more information about the 3mz block - 1mz head combination?
Is it easy to retain the awd? Maybe Any non 6gc that use it and boost that motor?
