Wow...ok where to begin....

The rb20det is out of the R32 GTS-T model skyline. It is a 2.0 liter straight 6 with a turbo that is a little larger than a t-25. [correct me if im wrong]. It puts out something like 210 hp and 206 ftlbs of tourque.

The sr20det comes in various flavors of toppage, but comes out of the jdm 240 known as either the silvia or the 180sx. It is a 2.0 liter 4 cylinder with something like 205hp and 200 ftlbs of tourque.

Both are damn easy swaps, but the rb is slightly harder because you either have to get a mounting kit or the r32 crossmember. You also need a custom dump pipe made for the rb. Both engines you need to have modified engine harnesses made by splicing bits and pieces from the original harness to the new harness....

Plenty of threads on this information and I'm tired of the debates... Inline sixies make more torque obviously, and the SR is a good reving and light weight engine, take your pick...
