Difference between SR and RB?

[Phil Megroin]

Hi,

I'd like to know - whats the difference between the SR20DET from the S13/S14.. and the RB20DET from the r32 GTSt?

Which ones better for mods.. which one produces more power/torque etc?

how are they different?

[Menthu_Rae]

SR is an alloy block, 4cyl

RB is a cast iron block, 6cyl

heaps of other differences... stock for stock, I think the RB has *slightly* more power, but *slightly* less torque...

someone who can be bothered to explain it all will be able to help out further

EDIT: some info!

Does anyone know what SR stands for? Cause RB was for Race Bread.

Don't make me hit you........ :fight!: (too late) And unless you are referring to a particularly racey piece of toast, I think you mean 'Race Bred' (which is still BS).

SR stands for Slightly Racey.

SR is an abbreviation for ste·ra·di·an

A unit of measure equal to the solid angle subtended at the center of a sphere by an area on the surface of the sphere that is equal to the radius squared: The total solid angle of a sphere is 4^pi steradians.
