Why is a 7AGE a bad swap idea when plenty of other Toyota 7A/4A cars are doing it?
After digging quite a bit on this forum, I find it absolutely odd a 7A anything and 4AG hybrids are frowned upon here. Why is that? Sure, it is easy to just drop in and do a 3SGTE or V6 swap, but none of that is considered unique. There are countless 7AGE/7AGTE built engines that are solid with no issues running around the MR2/Corolla forums...what makes the 7A 6GC Celica any different?? And 6GC member Nik successfully made a 7AGTE with 450hp.

I own a AT200 and have considered doing a hybrid swap as well. Granted a 7AGE won't net you much in the hp area, however, it does make the engine more fun to drive. For Toyota and the 4AGE, it was never about big power, it was more about fun and performance under the curve. A 7AFE by itself I agree has no balls with very little, if any, aftermarket support...but it still has serious potential that others on this forum have over looked. IMO converting it to a 7AGE puts your foot in the door to more possibilities and potential. The 7A block is favorable because it has a larger displacement over the 4AG engine, which to the 4AG crowd is great for those that want to move to forced induction. Just look on the 4AG forums, there are several guys building 7A blocks and swapping over. The head on the 7AFE is the big hindrance, once you change that to something that has a huge aftermarket following(a 4AG head), the modification and power possibilities now become endless. 4AGZE pistons do fit in a 7A block. And there are a couple shops that now make aftermarket forged rods for the 7A...with one shop making a 7A rod that mats right up to the 4AGZE piston just for this type of setup. That all makes for a complete bullet proof bottom end.

The biggest fable is the 'weak 6 bolt crank' on the 7A, versus the 4A and all others having 8 bolts. Truth is, there is no real proof in the 6 bolts being inferior...swap in ARP bolts and move on. One 7AGTE even had the flywheel fail and shred, but the 6 bolts still held on...and this guy is pushing 500hp thru his 7AGTE build. Some will even say the C52 tranny is too weak, but a lot of built +200hp 4AGZE guys are still running with the C52.

My own plan that I thought about doing: Adding forged rods and 4AGZE pistons. Buying a complete 4AGZE engine and swapping in the top end to have a running 7AGZE. And later, when I scrapped up enough funds, piece together a turbo kit and lose the supercharger. I scrapped my idea because I don't want to turn my Celica in to a full time project car...but maybe I should reconsider just to prove my point. haha

To the OP, in my opinion, if you want to get some real help on building your 7AFE, look on a Corolla or MR2 MKI forum. I believe many 7A 6GC owners here are duped by others on this forum in to thinking the 7A has no potential what so ever.
The real truth, anything that can be done to a 4AGE engine, can also be done to a 7AFE engine.

7AGE 16v - 7A block with 4AGE 16v head.
7AGE 20v - 7A block with 4AGE 20v head.
7AGZE - 7A block with supercharged 4AGZE 16v head.
7AGTE - 7A block with 4AGE head(can be 16v or 20v) + Turbocharger.
