I was looking for motors and i ran across i think it is www.total-boost.com and they have a bunch of b16, b18, and so on. The b16 is $2000 and it hs 168hp and 116 torque and a b18c has 170hp and 128 torque. I planning on using a garret turbo (thanks to pauls advice) t3/t4. But i am not sure if the 2 extra hp and the 12 torque is worth 700. Now from reading the b16 has a higher top end and the b18 has more lower end. Is that true? Would you spend that $700 or performance mod?
