h22=better out of the box performance, but with it you will need suspension upgrade to support the extra ~100 lbs up front, adding about ~$1500 to the price above.
you will not need to build the y8(as long as its relativly low mileage) to run 6-7 psi that a stock edelbrock turbo will run.. it wouldn't be a bad idea, but its not necessary, saving you around $1000 off the price above.
i could keep going, but im not sure if your concerned about price or power
properly tuned and built boosted d-series will easily make more hp than an civic needs... i pesonally would love a swap, but am completly content with what my d is/can put/ting out.
