I'd recommend reviewing your rebuild goals with a builder, as part of your planning. You'll save a lot of headaches with some simple up-front planning.
You'll need a larger turbo to attain 300 whp, stronger internals, upgraded fuel system, etc. and a builder or a performance shop can help you select items that are compatible and consistent with your target power goals and budget.
In general the more power you want the bigger the budget you'll need, something like:
1. OEM rebuild - 4 $k,
2. 300 whp - 6 $k, and
3. 400 whp - 10 $k.
I'm guessing with these approx. costs so don't hold me to them, but I'm planning an OEM rebuild as a result of this cost-escalation reality.
It's fun and exciting at the same time, but I only have a budget to do it right the first time.
