if youre doin autocrossing with this car theres no point in turboing. autocrossing needs high RPMs. go with the H22 for this situation. the turbo will run really hot if you push it to its limits for as long as an autocross event would be. if you do decide that you really wanna go turbo then go with a T3, T28, or T25. it wont produce a whole lot more power like a T3/T4 would but it would spool a whole lot quicker which is good for autocrossing. for a turbo check out www.f-max.com www.turbokits.com (dont really like that site) i believe theres also a guy on this board that sells DRAG kits pretty cheap. do a search to find him
