Highest N/A 6cyl?
 

I've been thinking about this lately with the introduction of the new Mustang V6, but as far as I can tell the VQ37VHR in the Nismo 370z with 350hp is the current record holder. Does anyone know of any mass produced 6cyl engines with more than 350hp?

We're talking NA from the factory right? Define mass produced. There were several TVR 4L I6s that were 400HP~ territory as I recall.

Yeah, N/A from the factory.

The NSX put out about 320hp in 2002, that's the closest I can think of.

I believe the next closest is the BMW E46 3.2L M3 I6. I believe it was 333hp.

You said V wigger.
