hey guyz...im new and owned a B310 sedan wif a15 and wanna ask some silly Q?..ur reply n consideration r much appreciated..

currently im using dgav32/36 on my a15 and it runs great...recently i had a dcoe40 for a quiet cheap bargain..it comes with an intake for A series and its oval port..my Q? is..

1. if i install a dcoe40 on my stock a15,do i have to mod the cams???why??

2. if i just install it without running any mild cams can it run smoothly or i just play with the jetts to suit my engine need??

3. is there any modification that i need to do if i wanted to install dcoe40??
