ok so i saw this website a couple of nights ago and it was explaining what each nipple on the sr20 throttle body went to...for instance top on went to fpr...bottom on capped off...and it was explaining that the wastegate shouldn't have a (tee) on it...so anyways if anyone can help, thanks

Wastegate valve solenoid, you can bypass it if you want to.

That diagram is all you need, if you get rid of a TB line on your car, just cap it. If you get rid of the wastegate solenoid, run the line from the wastegate directly to the cold pipe.

well ill just post my problem...my bov is on the cold side right before the throttle body. i have a nipple on my hot pipe...so i was thinking correct me if im wrong...

- my boost gauge gets its vaccum from the throttle body- my wastegate is connected to the nipple on my hot pipe...- my bov is connected to my throttle body- and my fpr is connected to my throttle body.

i am not to sure about the wastegate to the hot pipe?

let me know what you think, thanks joe

Wastegate gets signal from the IC piping. FPR, boost gauge and BOV get signal from the same TB port. Cap the other two.
