I was just on Wikipedia and came across the RB24.Which they make sound like it was a motor produced by Nissan.(at least thats what I took from it,which I doubt)

But Usually a RB24 is a RB20DET, with a RB25 Crank, and 4agze pistons (82mm). Not sure if you kept the 20 head.

But what they are saying is Using a RB25 BLOCK, and a RB20 Crank with assuming RB25 pistons. Haven't calculated it though.But think about it, you can have a big bore RB20 ish motorShort stroke Big bore motor.It wont have as much torque as a RB24 with a 25 crank but it would rev like crazy. Definetly not a drag racing motor.

Interesting but I don't think anyone would ever do it.Hint hint (I'm challenging someone to do it)

Nissan did build a RB24. I saw them in the Philippines in Cefiro's. They have single overhead cam heads and are carburated.

100% positive about that. I even stopped by a Nissan dealership in Manila to inquire about other RB parts.
