ok so ive been searching how to hook up my vacum lines on my rt sr20.

Ive read that the smaller vacum port on the tb goes to the fuel pressure regulator and can be teed off for your boost gauge. The larger vacum port goes directly to your bov. Does your wastgate go to a nipple off your hot pipe? i have a front mount can i just get a nipple welded on?

just want to make sure all the info i already have is correct

this might help you...too lazy to type it up in my own words so i got it from heavythrottle.com:
good luck

The vacuum lines are simple: 3 lines start at the throttle body. The bottom one goes to the canister, block it off unless you are using the canister. The larger one on top runs to the bypass valve (BOV), there should be no tee's or branches - go directly to the BOV. The smaller top line splits to the fuel pressure regulator, and runs across the front of the engine to your boost gauge and/or the boost pressure port on your boost controller.

i don't have a nipple on my hotpipe that goes to my wastegate since i don't have a boost controller...i have it tee off to my boost gauge

cool thanks a lot. would it be bad to get a nipple welded on my hot pipe and run a line to my waste gate??

^^^That could work too...

but wouldnt it make air blow into the line instead of it being a vacum?

Hot pipe is fine. It can see vacuum or boost. Only boost will open the WG.
