So basically to summarize if you want to run ACL Race Bearings:
DE/DET (non GTi-R blocks)
Rod Bearings - 4B2960H-STD
Main Bearings - 5M2964H-STD
GTi-R (54C) blocks
Rod Bearings - 4B2976H-STD
Main Bearings - 5M2975H-STD
VE Blocks
Rod Bearings- 4B2960H-STD
Main Bearings - 5M2975H-STD or 5M2964H-STD
Any other SR20 block can have the oil groove machined to fit the GTi-R main bearings, and std SR20 rods are 17mm but can be machined to fit the wider 19mm rod bearings.
