7afe's are basically a 4a block stroked from 77mm to 85mm (1597cc vs 1762cc). Making yourself a 1.8l 4ag is pretty simple. Go find a 7a block from a mid 90's corolla, celica or prism and bolt a 4ag head onto it. It seemed simple enough. I couldn't find a cheap 7a, they were all good running engines, bummer. I had to pay $450 for one from a 95 corolla, it even came with a warranty (like I would need it). I took apart the 7a and threw away the head. Next I took apart the small port 4ag. I put the small port pistons in the 7a block on the 7a rods. You can only use 4ag pistons with a 20mm wrist pin on 7a rods, I think anything made from 87 up will work. You don't want to use the 7a pistons they are dished and with a 4ag head your compression will be under 9:1, not good. When you do this you have to get the wrist pins pressed in. I should have had them modify the rods to floating wrist pins but I had no idea at the time. Next I put the 4ag timing gear on the 7a crank added a set of arp rod bolts for a little extra safety at high rpm's. 7a's use metal head gaskets that look a lot like trd headgaskets so I bought one from the dealer with a full gasket kit for a 4ag head. Next I had a valve job done on the head, I wanted this enigine to run perfect. I used arp head studs to torque down the head and put in my web cams and cam gears. Finding the right timing belt took a few trips to checkers but a 86 porsche 944 belt fit pretty good. Since the deck height is higher on the 7a block the cams wouldn't line up, they were both off about 1/2 a tooth. This is no problem when you have cam gears and I would reccomend anyone doing this to either buy some aftermarket ones or slot your old ones.
