Weird thought

Frupal · 12-18-2019, 01:58 PM

I wonder if anyone has ever dropped an M4 engine into a 640? Possible? Silly? How say you?

Why would you want to? The N63tu makes more power and is already available in the chassis. The weight savings would not be worth the effort.

It was just a thought. Mine is a 640 and I thought that perhaps the M4 motor might just drop in. But then I realized I’d be better off just buying a 650.

s55 10x better motor than an n63 will ever be.. but the time and effort and cost to put an s55 in there your better off with the s63 m6
