Seriously though combining the 4A head with the 7A block isn't straight forward at all, the 3S onto a 5S isn't so bad for some reason but the 4A onto 7A is. A lot of things had to be redrilled or re-tapped and modified. I think the timing needed a 944 belt and adjustable gears or something like that. Anyway, unless you can do all the machine work yourself you're paying out good money just on that and hoping they get it right. Finding someone that knows modifying Toyota motors beyond the 2JZ or 3S is like finding gold in your backyard. Never meant to discourage just to say there are easier and most likely cheaper means to an end. Anything can be done with enough time, money, and ingenuity, we have a member that converted his to a RWD 5S-GTE drag car.

And of course Norberto with the 2GR which I was always for by the way.

Incorrect. The 4A head does bolt right up to a 7A block, it is straightforward. The blocks are identical except for height(which is why you need a longer timing belt off a Porsche 944). Both head gaskets fit. I'd refrain from putting out mis-information here unless you absolutely know for sure what you state is true.
Finding a 4AG mechanic is just as easy as finding a 3S or 2JZ mechanic. Everyone is working on 2JZs now, and 4AGs have been around longer and have a larger fan base. 4AGs have been used in just as many, if not more, racing applications than the 3S and 2JZ.

No I'm pretty sure the oil or water jackets had to be machined so they lined up perfectly which is why I ended up never doing anything with mine, if I find the post off whatever Corolla forum it was that had a comprehensive list of all work and parts needed I'll post it. Not so sure about the 3S, Toyota used it in their GT500 MKIV Supra before using a modified UZ V8 at the end. Of course it was also used in the WRC Celica through the generations as well. Kind of ironic the MKIV Supra never raced with the engine it was sold with as a street car.

You wouldn't have to rebuild the 7A for a few pounds of boost if you can get the oil rings freed up. Hot Shot's stiction remover is guaranteed to remove build up and free rings, but it was pretty costly when I looked into it. Using Marvel as a piston soak was enough for mine and it's right under $4 for a quart which lets you use 8 oz per cylinder, and then after that you can let it stay until you're ready to change the oil. If doing an oil change soon you could use something more aggressive like the various oil flushes out there and that should do even better at freeing up the rings.
