i have a lexus sc400 with a 1jz 5spd swap.
i have a 89 s13 with a rb20-25 swap.
i have like both engines,hence why i have them both. oiling issues aside. you have to do a Fair! COMPARISON
the rb25 vs the 1jz 2.5 vs 2.5
if you want to compare something to the 2jz you need to compare the rb30. then you have a even steven comparison!!
