wastegate vacuum to hotpipe or outlet pipe - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Po_31 · 10-05-2012, 02:14 AM

first of all i have a sr20det

I would like to know if anyone has actually installed a hose fitting or something else into their hotpipe as a means for the vacuum to the wastegate? i seen some people on different forums drill a 1/8 npt to the turbo outlet pipe instead, would either one of these work which would you choose
thanks

just get a t-hose barb connector and cut on of your vac lines and run it from their. its simple no need to drill anything.

I don't know why.everyone thinks its ok to t off a vacuum line. internal waste gates aren't supposed to see vacuum and is clearly shown in vacuum diagrams. weld in a nipple to the hotpipe, that's how I have mine setup.

If you want to run it to the manifold just run a one way check valve. Wastegates need a BOOST source.
Hotpipe/compressor housing

sorry to get in the thread but this is how I have mine set-up. do I need to change anything on it?

I'm using option 2. is it right?

i drilled a hole one of the couplers on my hotpipe then used this for my actuator

Turbo Quick Tap Fitting for Boost Source

works great. the closer the line to the actuator the faster it responds
