you can't get them the only thing you can do is modify the wrist pin on 4age forged pistons to fit in the 7afe but it will raise compression

you can do this, but your compression will go up to the point where you really can't boost. Forged 4ag pistons bring you up to 11:1 compression.

actually there is no modiffication needet to fit the wrist pin, it is the same diameter as 7A wrist pin, only difference is in locking (4A wrist pin is locked by 2 springs, and 7A is pressure fit). The compresion on the engine will jump from 9.5:1 to 10.5:1 (not 11:1). But it can be fixed by using bigger head gasket (somthing like 1.2 mm). so you could have 9.5:1 CR and forged pistons..

Ok,wait wait...JE makes pistons for 7AFE, if you ask them they'll confirm.
I used 4AGZE pistons bored to 82mm rated 8.5:1 and in my 7A I got 11.06:1 CR.
As doggy said ya can fix is with a thicker head gasket, anyway if ya'r gonna to up the boost I suggest you to get forged rods, cuz when I had 7A rods in my hand I realized that they are so thin...
Just a suggestion wink.gif
