I have a evo 8 about to install an Fp Red into my car. I have the stock o2 housing and of course want to upgade. My question is whats better to go with, just a aftermarket o2 housing or an o2 external wastedump? i dont really know what the o2 dump is for and if it helps.

This is the set up so far for the Red turbo. let me know what else i should get or change.

Ets IC
injen full piping (going to change to Ets)
Full turbo back
255 fuil pump
1000cc injectors
stock manifold (not sure which to replace with)
hallman boost control

an thats all i got for now.
my performance goal right now is to get street power on a stock block.

let me know what you guys think.

thanks
