+1 stay away from XS... If you do go XS don't buy the wastegate. Buy a good, well known wastegate to avoid boost creep and killing something.

Go with a less expensive manifold and a better wastegate for safety. Also +1 on the DSM 450's. Don't forget to add a fresh fuel pump to the list.

o and as you can see from my previous post... Stay away from D motors... They will NEVER have any power...
