do you think it would be possiable to get 300hp on a bored and stroked B20 sporting maybe 12:5 compression B16 head stage 1 port and polish and some good cams with the bolt on goodys? thanks

 

check out all-motor forums dude, they can help u out better.

 

300 HP? thats a stretch for and all-motor build without the financial aid of sponsors.

This guy knows his stuff (tuner/builder) - you'd need a lot of luck & $$ to do better than this by yourself.

 

12:5 ..i hope u have high octane gas in ur area. i wouldnt say around 300 may in the mid to high 200 hp range . but i think you'll get gobbs of torque. but 300 may be possible im not sure . try looking up other ppl s builds and see what power are they putting down to the wheels. then build ur setup based off of what they have. but yeah.. its all about money . if u have the money u can do anything other than that 300 b20/vtec is more than possible with turbo, but for N/A i dont know u can try.! good luck.!

 

well tunned yeah shouldnt be a problem and on top of that add a 75 shot and call it a day
