4age silvertop 7 ribbed 92-97 (42mm crank 20mm pistonpin) 20v (44mm ITB) VVTI
4age blacktop 7 ribbed 97-01 (42mm crank 20 mm pistonpin) 20v (48mm itb) VVTI

The 4age from 87.5 - 89.8 is 7rib block without oil squirters 42mm conrod and 20mm piston pin. All the 7rib engines are 42/20mm

For an AE86 the best option is to buy an engine from late AE92. Its the same strong engine like the 20V, also has piston cooler oil squirters, and you don't have to sck with the waterlines and so.... This could be the best base if you want a relyable a tuned engine. The cyl heads are changable and you can get a bigport head cheap if you decide that tha smallport is too small. But I think you can get 220hp from a smallport also if you are very good in tuning.
