have a 2.1 cdb built and now i wondering what the best heads would be to use or would the original heads on my sti9 blob uk be the best???
any advice would be great!!!

 

What power are you aiming for? As your current heads will be ok for 500+

 

Also whats the car going to be used for ?

 

its an everyday driver with the intention of a few trackdays...the most power i want is 450 which i probably wont reach without more mods...
thing is i drive this car everyday and need it back asap so if i bought s/h heads and fit them to the short block so could fit t.belt and other bits on engine,i would only really need to swap inlet manifold,clutch and turbo,exhaust etc..

 

Stick with what you have

 

as above

 

get some of these if you got some spare change http://www.cncheads.co.uk/subaru_impreza.html
