what is the best type of springs and retainers to run in a boosted 99 civic si with a drag kit. ive been searching around and i found out skunk2 and super tech makes awesome springs & retainers .So far all i have for the head is 2000-2001 brand new type r cams and aem cam gears .would like some opinion from u forced induction guru's.

its all about personal preference. I run Supertech that I got from Earl. I know there are alot of people running Ferrea(sp?), Skunk2, Jun, crowler and many others

i run ferrea stuff with great results.

ive also used skunk2 stuff on street cars in the past with great results. but we were ringin the **** out of them, so i dont know how they would hold up on a race car.

I was taught a rule by an engine builder and dont know how to apply it to choosing the right springs - basically you need 1lbs of added closed seat pressure per lbs of boost you plan on running. i can find the stock spring pressure but does any aftermarket producer make their specs available?
