Yes you can.
Yes they will
yes they will !
Not without modification (... but WHY?)
Yes it will, the only difference is that the SC300 is a 6 cyl. and the SC400 is a V8, the body is the same for both.
Not without modification (... but WHY?)
Anything is possible, but that would take more work than the car would be worth.
The SC300 and SC400 (but NOT the SC430) are the same body and many of the parts are identical. I do not know for certain, but there is a very good chance that a windshield that fits an SC300 will fit an SC400. They might even be the same part.
yes they will fit with no problem rubs the fender well in the front a little
the Lexus sc300 has a 2jz-ge. and i have some friends that swapped a 2jzgtte into the 1uzfe's place. so, to answer your question.... with a lot of work it will.
I would say so as long as the diameter of the pipes match
well it's been done sort of , manual trans anyways. google top secret v12 supra.
The transmission from a Toyota Supra is not a direct fit for a 1993 Lexus SC400, as they are designed for different engine and drivetrain configurations. The SC400 uses a 4.0L V8 engine paired with a specific transmission that differs from the Supra's inline-six options. While some modifications might allow for compatibility, it would require significant alterations to the mounting points, driveshaft, and possibly the ECU. It's advisable to consult with a specialist or perform detailed research before considering such a swap.
