How do the Toyota v6's used by lotus differ from ours?
Beefed up internals?
I would be willing to bet they are, "beefed up" in many ways. I can all but guarantee you they simply are not taking a stock V-6, normally aspirated engine, and bolting a turbo system on it.
Even with factory turbocharged engines, the 2 rules of thumb are, never buy a used one. And never buy one that is out of warranty. Because they are a financial nightmare to repair or replace. Remember, the factory tests these engines for literally millions of miles. They know precisely how long these engines will live. And set the boost so the engine will live past the warranty period. Yet still deliver noticeable performance. Or else they won't be able to sell it.
I have never understood the logic of these turbocharged 4-Cylinder engines. If you compare for example, the Camry with a V-6, to the new Honda 4-Cylinder Turbo, they get identical EPA fuel economy ratings.
But BOTH the Toyota V-6 AND THE 4-Cylinder have more horsepower, without all the complexity and cost of the turbo system. And it costs less to purchase. And no one is going to tell me that BOTH the Toyota V-6, and the normally aspirated 4-cylinder won't live longer if properly driven and maintained.
