4age differences


JDM AE86 came with the 4AGE-U (DOHC 1.6), ventilated fronts and soild rears. Vs the ADM "AE86" which had the 4AC (SOHC 1.6l), Solid fronts and drum rears and had more in common with the AE85. JDM U13 Bluebird SSS had the SR20DET and AWD vs the ADM U12 Bluebird SSS which had a KA24DE and front wheel drive only. Intake comparison on 4AGE 20V BlackTop What performance gain to expect when replacing the original plenum by open velocity stacks Here's a little comparison on the Toyota AE82 Twin Cam GT from Sushi Express rally team : checking with PerfExpert the difference in torque and power between the original plenum and open velocity stacks. There are two crankshafts available for the 4AGE, the 'small' one which has the big end journals of 40mm dia, and the 'big' crank which has 42mm big ends. The big crank weighs about 700grams more than the small crank, (~11kgs Vs ~11.7kgs) and up to about 200hp - 220hp it is stronger, but in practice there is little difference between the two cranks. 4AGE's come in both front and rear wheel drive form, and although they are very similar, there are a number of small differences that make swapping them over not quite as easy as it would first seem. I won't be getting into that area, as a good friend of mine, Phil Bradshaw, has already written an excellent page on doing just that.
