Now THAT'S a supercar, folks.

Doesn't look terribly difficult.

All that work and you could just add forced induction to the stock 3L and get the same power levels. I am not sure I would have done that. The cool factor is off the chart. But.. . . .

Yeah... Obviously the 3.0L will never have the torque curve of the 7.0, even with a blower, so while you could possibly make the same peak #'s, the LS7 will out-perform it due to a much beefier powerband. Also, the LS7 weighs 35# less than the stock 3.0 and you are talking about adding even more weight to it.

Is that including weight of trans? I'm having a hard time wrapping my brain around how a fully dressed LS7 drivetrain can weigh less than an all-aluminum 3.0 V6 drivetrain.

Not calling you a liar, because i really don't know. But if that's true, that's astounding!

Even so, i'm not a fan of the swap. Of course, i never really thought an NSX needed more power in the first place. (Shocking, coming from me)

My first instinct was to make a 'your mom' joke about this, but it just doesnt work. Comedic instincts have failed me again.

The NSX has gigantic cylinder heads, and a big heavy aluminum intake manifold. That's probably where most of the weight is saved.

That was according to the builder, who weighed both. Pushrods are lighter than OHC's, the LS7 is dry sump, and a plastic intake manifold is lighter than alloy. I can easily see it.

I am strictly looking at $$$$$ versus fun. I bet that swap is easy a 10K project where as adding forced induction should be doable for say 5k???? Ya ultimately the LS swapped car will be a better performer but for half the $$$$ you would end up with something close.

To the best of my knowledge, nobody has put one in a Paseo. And since a Paseo only LOOKS like a hatchback, it might not even fit.

Impressive, but I personally don't think any LS engine compares to the NSX engine in refinement and sound. Engine swaps should be for cars that need engine swaps, not those that don't.

Honestly don't understand. I don't speak subjective, though. I don't understand what "refinement" means.

You want to start a discussion about "quality" as well?

Don't understand - "quality" hasn't been mentioned in this thread at all. Is this an inside joke that I am missing?

"need" is a relative term in the engine swap world. Spun bearing, burnt piston, whatever reason.

I'd wager a second-hand LS motor is cheaper and more available than an NSX V6.

I'd also wager that rebuilding an NSX V6 would be cheaper than swapping in an LSx.
