Crankshafts
- Early 4AC and 7AFE engines had six bolts on crankshaft to hold the flywheel on while the others all had eight bolts.
- The AE86 and AE82 bigport 4AGE engines all had 40mm diameter big-end bearing diameters.
- The AE92, AE101 & AE111 (japanese levin/trueno only) 4AGE smallport and 20 valve engines all had 42mm big-end bearing diameters.
Pistons
- 4AGZE pistons are semi-forged and have ceramic tops. They can be bought new from about AU$80 each, So are a fair bit cheaper than aftermarket brand name forged items. They come in 8.0 and 8.5 Compression ratio sets. These pistons have made 200rwkw so cant be to bad for a stock item.
Con Rods
Here is an example of Carillo "Formula Atlantic" Conrods to suit a 4AGE.
