ok so whats the pros and cons of each and some of the specs in diffrences and so on and so forth
LOL ^
rb 20 sounds way better
that was no help at all.
inline sixes you can rev the hell out of are always good
plus you can probably get one cheaper than an sr
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.
