H22 mods...i need help

[initial]

okay well... i got my H22 in, and it runs strong. now im getting ready for winter where the car will be parked and sitting under the roof of my garage/ import tuning shop. =)

 

but okay, during the winter. i tune, or at least mod alittle. and with this car, i got alittle going. bcuz its not street legal anymore, and after i tuned up the fuel system and got a full out engine management free from my neighbor, i want to do more.

 

on the H22,

-is the Euro R intake manifold better, for horsepower? YES or NO

-is the type S camshafts better, for horsepower? YES or NO

-is the type S pistons better for horsepwer? YES or NO

 

in better i mean will it give me horsepwer...? i dont know much about the type s or the euro R cuz it wasnt going in my car... so please help... thank you.
