Nope. 2001 1.8t has VVT (variable valve timing) and 2000 doesn't. In fact the '01 engine was overhauled quite extensively to attain ULEV standard (first turbo engine in the world to attain such emission standard). In addition to VVT, it also got different software (runs more boost, 9 psi vs 7 psi) and different internals (cast pistons vs. forged ones in earlier engines, not sure about crank and connecting rods).
2000 1.8t gets ~205hp when chipped, and I believe 2001 gets a few extra ponies generally.
