I find alot of different fourms and threats saying different things on the sr20 stock boost line set up. So im not too sure whos right. Can anyone tell me if my lines are set up right?

top left nipple goes to the boost/vacuum gauge, the fuel pressure reg., and the wastegate. the top right goes to the BOV. the bottem is blocked

This is assuming a stock throttle body.

The biggest hose barb goes straight to the BOV. No teeing off of this line.

The bottom small barb goes to the EVAP charcoal canister. If you're not running the canister, block off this port.

The last port on the TB goes to the FPR and boost gauge.

The OEM routing for the wastegate is off of the IC piping.

There is a lot of debate about where the optimal wastegate signal can be, but as long as it's somewhere on the IC piping you'll be okay.
