On another note:
With the partnership with McLaren in 2015 in F1 and McLaren talking about a smaller less expensive street car to compete on price point with Porsche. It might be interesting to see if they tap into the NSX power plant or maybe a detuned HPD engine used in Indycar or the new GrandAm/ALMS series.
I'm sure once the Mercedes apron as been severed on the F1 end; Honda maybe a natural choice for McLaren's street cars
Just a thought
its possible, but I'm going to doubt it. Honda is not going to produce an engine just for McLaren unless they have something to use it in. Now that could be shared between the NSX and McLaren but I'm prety sure Mac typically goes with a flat plane set up, while the new NSX is going to be a cross plane. Mac isnt exactly helpless when it comes to building engines, the MP has a McLaren built engine and they own the rights to Walkinshaw racing and all their engine dev work.
