getting B20 to 1.75 r/s

now that I have something to put it in, I want to build a crvtec soon. I used to want to go all motor, but I am not sure if a mid 12 second car will be fast enough for me. I know that sounds weird, but I want my car to be REALLY REALLY fast, problem is I also want it to be my daily driver.

this is what I had planned to start from:

B20b block, B16a head, crower econo billet rods,JE 10.5:1 compression pistons,AEM cam gears, crower stage 2 cams, 310cc injectors,new bearings and rings, AEM V2 CAI,DC sports 4-2-1 headers
Exhaust (friends muffler shop), Jacobs F-1000 ignition.

but what all does it take to get the b20 to 1.75 r/s ratio so I can rev higher and doesnt the perfect ratio take boost better as well.

I think i remember reading the stroke or the B20 being 89mm, so if i was to have custom length rods made, how long.

well, 156/89 =1.752. so does that mean I should get 156mm rods made. (whioch turns out to be 6.14 inch and the rods from crower for a b20 is 5.3 inch and im guessing that extra inch is gonna stop my engine from starting when the piston hits TDC, and probably bend a valve. so then I need to get a new crank, say i stick with rods from crower for the B20 at 137mm, now i need a crank with 78mm stroke. 137/78 = 1.756 but now my piston travels almost 1/2 inch less. so when it gets to TDC, it is about 1/4 inch farther away from the head, which isnt much compression anymore. would the 12.5:1 pistons make up for that.

what do you think of this setup:

B20b block, B16a head, crower billet steel rods, custom crank with 78mm stroke(any B series come with that already?), JE 12.5:1 pistons(would actually be lower cuz of short stroke, correct?), rev hard stage 2C turbo kit, 310cc injectors, MSD BTM(retards timing as boost increases), lightened flywheel and ACT stage 2(strong enough),

Id probably still get litle things like AEM cam gears and lightened pullies, etc...

also, probably turn up the boost a bit to like 11-13psi, and eventually some engine management system.

how possible is 300+ wheel horsepower with this setup. another question, what kind of gas mileage should I expect out of this.

thanks in advance

im not sure if you can without losing displacement and if you go with reallly high domed pistons it can can cause problems because it forces the A/F mixture away from the spark plug. ive thought about the same thing but now am thinking about a sleeved and bored B16a, it wont have the torque but i figure the revability will make up for it
