11-12psi will be fine, maybe even 10 on the safe side, with a decent size t3/t4 turbo you prolly push out low 300whp

The GS-R head doesn't flow as well as the B16 PR3 counterpart, since you are using forced induction the better valve-angle of the GS-R head will help you make more power.

Turbo > Supercharger any day of the given week. The Supercharger is going to use more fuel to make the same amount of power of a turbo (gas mileage). A T3/T04e Turbo should work fine.

As far as compression goes.. I'm in the dark. From what I've heard 10-11 range is a good way to go since we live in an age with more advanced engine management technology and research.

Which computer were you planning on using?

I have used Uberdata before and have created a few custom chips but nothing major just bringing in vtec at a different point, setting fuel cut at a different point and import different fuel maps others have created off of a dyno with about the same setup I had. I know all motors are different and I should had mine tuned on a dyno with my own maps, but all I had was basic bolt ons and I wanted to see how the car ran with the different maps. Prolly use Hondata or crome. there are a lot of tuners around that know how to use that.

Just wondering.

I was thinking about boring out the block of the B17.. but the deck height is so darn short.. So I think this will stay a 1.7L.

If I didn't want a K-Series so badly I'd go all-out on the B-Series.. but a B can't touch a K.
