Was going to say the same thing myself... 12A from the original Rex is just about the only one... High-output, small engines weren't too popular back thenOriginally posted by: Kremlar
How about a rotary.
1978 RX-7, 100bhp @ 6000rpm, 1.2 liter.
Good numbers for it's time, though modern day engines are obviously more advanced.
Not familiar with racing engines of the 70s.
not from that era i don't think... and not that small, either.Originally posted by: Viperoni
Weren't there some Mustang or Dodge engines that spun up to 7k?
Not so, look into the old Indy car motors.Originally posted by: brian_riendeau
Thanks for the good info. I am not looking to purchase a motor or anything, I just need some examples. Got in a bit of an argument with someone who was saying that in the 70s and early 80s, the only way to make a lot of power was with a huge turbo, or lots of displacement
