you dont believe that "280hp" gentelmen's agreement crap, do you? the rb26 is over 300hp stock, and the block is practically indestructable. the 26 is only about 100lbs more than the sr, and that wont throw off much, since the sr is also lighter than the ka that came out of the car. I'm just exploring my options, and trying to be creative since there are so many SR's around. No disrespect, just finding a niche....
