why not just go with an rb25 if you’re thinking about swapping an rb20 in there?

Go with the rb20, it’s from a skyline, there’s a reason why nissan put that engine into a skyline.

Also, you can safely rev the rb20 to 9000rpm on stock internals but the sr20 can only handle 7500rpm.

The rb20 also has 2 extra cylinders which means more torque.
