I have a 1976 Corolla whose 3K engine is on the way to being overhauled. I am inclining towards swapping the engine to a modern EFI engine to get more power from the engine. I have a few questions:
1- What engine is best for swap? I am more interested into minimal modifications. I know that 7K would be bolt on fit, but it is a truck engine and on paper there is not a huge power difference between 3K and 7K
2- I had initially planned to put in 3SFE as it was available in rear wheel drive, but it needed new mounting plates to be installed. I decided against it as I have seen a few engine swap with mounting plates that transfer a bit of vibration into the body. Somebody said 4SFE would not need mounting plates and would sit on the same mounts. I don't agree to this as it is from the S series family and should have the same mounts as a 3S thus needing mounting plates? Correct me if I am wrong
3- What about swapping a 4AGE? Any pros and cons for this engine. The fuel quality in Pakistan is not good so how to run it effectively here
4- What if I stay with the current engine, how can I increase the power to a decent level? Don't want a drag car, just want something that can be used occasionally with minimum problems and has a bit of power when needed
Would welcome any suggestions in this regard
