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".

Since there are more than one cars with that kind of swaps I dont't find it useless.
It's a conversation that may help some people built a better car. like kurts v6 celica and other 5s celicas.
I have seen a local old lexus running a 1uz v8 with 0.4 of boost with stock internals.
The owner used it as a drift car and won several races on the local championship against fully built monsters and the 1uz was completely stock. Just a turbo kit attached on it.
He said that the 1uz has semiforged internals that can handle boost till 1bar!!! I'm not sure about that but the car was on track for several years till the regulations changed and he built another car accordingly to new regulations.
He was abusing and racing that engine like there's no tomorow. the engine had put 420whp/5800, 650nm/3500. (0.42 bar)

Back at the point.
It would be interesting to put a turbo v8 on the celica.
The cost would be
-a complete 1-uz swap for 1500 to 2000 euro.
-custom mounts for the engine and transmission or an adaptor for the E154 around 1000 e
-a custom turbo kit around 2000 maybe 3000 e
-an aftermarket ecu (emanage ultimate maybe) for 500 e
-some other stuff like a boost controller, some gauges and couple other that I may forget 500-1000 e
-the work that needs to be done from a mechanic - electrician - tuner 1000 or maybe 2000 e
so approximately 7 - 10.000 euros

you can achieve that hp number with the 3s. I know. but the v8 would be more fun to drive and has more potential.
That's a completely stock motor with just 0.4 of boost. civilised - daily - reliable.
If you add some forged internals and bigger turbo set up ......
