Well, all I know is, I don't want that 4.0L V6 from my 4Runner even in corolla. The engine is just too lazy.. YUCK!

I love Torque. Bring out the common rail Bi Turbo V8 Diesel that they have in the JDM land. Turbo diesel are so sweet in the SUVs.

Don't think you'll be able to do an even swap, lol

The LX's engine is designed to carry a heavy vehicle and to tow a lot of weight. That's not required in a sedan. You don't need such an engine. We are talking about heavy crankshafts, connecting rods, pistons, etc. With that larger engine coolers. Try to squeeze the LX radiator into the GS. It might not fit.

I believe peak HP and Peak torque or differently tuned from a sports car to a truck. Also remember the LX's transmission is designed to work with this engine. While Lexus sport utes and extremely smooth transmissions, I hardly think they are suited for a sports car.

We need an engine engineer to comment on this, but I don't think it is as simple as "torque is cool", I want this truck engine in my sports car.

I'd gladly swap my extremely underpowered RX300 3 liter for this. If I'm not making enough money in a year to lease this LX, then I may just have to do that. hahah

That would work great!!

I'm finding it hard to believe that these SUVs and trucks are keeping up with my LS4. Now I need a GS430.

As opposed to what? Not making any torque? All vehicles make torque, or else they would have any horsepower. I think you mean: power in the low-rpm range is awesome as opposed to much higher power levels in the upper rpm band. You want a Mustang 5.0 type motor or a M5 type motor? Both are 5 liters and both have completely different powerbands. One of these engines is not like the other...

A motor that makes more horsepower is faster so long as the gearing doesnt hose it. This whole torque-myth has GOTTA go. You don't pull a boat trailer with torque, and you don't accelerate down the quarter mile with torque... Torque is a static value, check it out; its basic classic physics. Horsepower is torque applied over time, an actual useful value. This is why F1 cars make crappy peak torque values; but have ferocious powerbands and the gearing to take advantage of them; and why trucks that tow need to have fatter powerbands in the low and mid rpm range.

The 5.7L would be a poor choice because of gas mileage and possibly weight. The 5.0 is quite capable of making plenty of power; peak torque numbers mean absolutely nothing... just because a car has big peak torque doesn't mean it has a good powerband. Not saying the Toyota 5.7 doesnt have a good powerband; I'm saying the 5.0 powerband will be far superior for what the GS-F and IS-F will be engineered to do (and thats kick *** and take names).

Its all about designing the engine around the spirit of the vehicle that it will power.

Too bad it wont have the 8-speed guess we have to wait another 6-12 years for the next LX
