How come you have a 2TGEU with carbs? It should be EFI.
EFI won't give you more power. If you have a nice set of carbs and they are properly tuned by someone who knows what they're doing, then you'll be perfectly fine for normal driving.
The 2TGEU is a better candidate for a turbo than a 2TG, due to the lower compression of the 2TGEU.
If you want max N/A power, then go for your old stock 2TG with carbs. It's a lovely engine.
