ye you can go f serries then.. or you could go zc, or heck to be really diffrent go k20 or sumthin..

 

F-series isn't really worth it...it's not powerful enough for it's weight....i'm actually thinking of going turbo D16 for now...until i can come up with something better....not exactly different...but it'll get me where i need to go...we'll see...i'll keep you guys posted...

 

booo D turbo.....

boosted B > boosted D

on a side note...if you are interested in autocross...why would you turbo?

 

h22 are highway motors. go with something else for autocross
