The H-series has been out of production since 2001. So the supply of motors has become limited and prices have risen accordingly. A well-built B20 can easily compete with the H22 when it comes to power..and there are a lot more B-series mills floating around than H's.

I would recommend a B20Z. You'll be able to keep AC and power steering and still have a wide powerband with plenty of torque.

Strip the B20Z down and port the head. Bolster the bottom end with forged pistons and rods...keeping the CR somewhere near 9.5:1. Reassemble the head with Crower's 402 "turbo" camshafts and so on.

Assuming you can find a B20 for $850 or so, you'll have a very strong motor ready for FI for less money than you'll spend on a B18C.
