now i have a better understanding of how to get what i want from the b20. now i have a new question i want to build the motor for autocross and i've been told i need a wide hp curve which i still want to be around 300 to 350 max so should i go with a t3 ball bearing which i know is going to be real expensive or just supercharge it which i know from previous experience on domestics will get it the way i want but again still pretty new to 4 cyl. short block. please remember b4 u answer that i need a broad power curve for auto-x appilcation
