This NSX With a K20 Swap is INSANE – YES A K20 SWAP

By -

We don’t know what to do with our hands. Seriously.

World renowned, the NSX is just about as close as you can get to peak driving perfection. It didn’t come on to the scene with a guns-blazing attitude, but instead with a hearty V6 and a drive-it-daily attitude. But what if someone wanted to swap in a completely insane engine?

A V8? Probably. But you probably wouldn’t expect it to be a 4-cylinder.

But here we are, an NSX with a K20 swap. Before you even cast doubt, know that this engine produces almost four times the horsepower of the C30A V6. For that, we’ll give the idea a nod of approval, and even a pass. But where it really wants to pass is down the 1/4 mile.

So here’s the details. The car was bought and built to be raced, as the owner had discovered the car was involved in a crash, despite a clean CARFAX. That tells us the crash was small, but the seller stresses it anyway. There’s also the engine swap. You’ll have no loss of power with the K20 as it is turbocharged to the max with an estimated 1,000 horsepower.

It’s not a street car, though, even if it is road legal. All the comforts have been removed for the sake of 1/4 mile times. But if you can overlook that, and don’t mind the $42,000 price tag, then maybe this is the car for you.
