Yeah the block is good for it.

All the blocks are the same like I said, and people run 300hp all day no problems. I rarely if ever hear of big turbos with issues.

As for chipped cars at 225hp you never hear of issues. The stock turbo is very small and from the factory the 98 1.8t probably runs 8psi, chipped it will do 20 psi giving you that jump in power up to the 200 range, and the engine handles the extra power fine.
