4age bearings

[trikzlane]

what i want to know, are rod and main bearings the same in bigport (3rib) and smallport (7rib) blocks (ie standard sizes)

[slide86]

there are differences in cranks........40mm and 42mm

im pretty sure that 3 rib was the 40mm and the GZE and 20v and smallports were 42mm

someone correct me if i am wrong

Best description is
3 rib = 40mm 18mm
7 rib = 42mm 20mm (as this includes some MR2 early AE92 bigport low compression motors. All have the big crank.)
