I think most will advise you to do the 2ZZ over a 4A-G if feasible.

4age will be easier, but finding parts may be a challenge later on. But might be more available to you versus here in the us.

The weak point of the 2zz is the material in the cylinders. It's called MMC and it can't be honed unless you sleeve it first to generate more power. The rotating assembly is shorter as well. If you plan to boost the 2zz, it might not be worthwhile in the long run. If you find the supercharger from Greddy, then that's a better option.

2ZZ is way, way faster than 4A-GE, even silvertop/blacktops.
Fastest swap of them all is 4A-GZE. Get last generation with more boost! :)
Forged internals from factory is ready for more boost, can get 500-600bhp!!!
Best bang-for-buck or bang-for-effort (hours), nothing gives you more power-gains per/dollar or per/hour spent than 4A-GZE!

2ZZ is a badass motor. With the 2000 Celica GT-S ECU you get lift at 6,000 RPM and redline at 8,250 RPM. It screams. Lift kicking in is a nice feeling. It's a really enjoyable engine that makes good power.
It is a bad ass motor. But it has its flaws.

MMC lined cylinders. Can't be machined if the get warped. Sleeves need to be installed then bored out for more ponies.

Front oil pump, design flawed as it gets destroyed due to low oil if the previous owner kept oil levels low or just trashed. One of the biggest causes of death to these motors were miss shifts.

Oil pan doesn't have a baffle. Can always modify a 1zz pan which has a baffle. Go figure.

Though the 4age is older, it was designed to take more power by design. It's not as high revving as the 2zz. The only issues that I see is finding a complete harness and ECU. If you check your local Craigslist and will find a 20v with trans, harness, engine and ECU. Might get a deal there. It may cost more in the long run to get more power gains on a 4age, but it's a cast block and internally stronger.

The 2zz is cheaper due to newer tech. You want this set up, best to check the local salvage yards.

Best engine to source is 00-01 Celica gts. It's because this is the highest hp engine out of the 2zz family of engines.

If that can't be located, then 03-04 matrix xrs or Pontiac vibe gt. These were rated closer to 180hp and didn't have the air injection set up and the lift point was lower.

Then finally, 05-06 Corolla xrs. This was the lowest hp offering for the NA market. It's 160hp as the Corolla is your everyday commute model. Not sure why it was detuned for the Corolla.

You could unlock the potential by using a Celica GTS ECU with the 2zz out of any above. Just make sure you use the harness also. As mentioned before, the celicas did not have the air injection pump at the end of production.
