OKay when i bought my gsr the secondarys weren't hooked up.I dont know which vaccum to use for it.And yes i tried to look at my friends gsr and its under the intake manifold.But heres my question. The secondary is closed when there is a vaccuum on it right?Mine doesnt have a vaccuum on it because it stays open because my ecu does not trigger the sceondaries to open.but the question is this.Since my car is now turbo'd can i hook up the vaccuum from any vaccuum sorce to it so that its closed when in vaccuum,but when boost kicks in it will open because it wont have vaccuum to hold it closed?Will this wrok or will it not...?what do u think?

 

Get a blox manifold , no really the gsr manifold flat out sucks

 

Just take out the butterflys, or go with an aftermarket unit for your forced induction setup.

 

the last GSR setup i did we just hooked it up to straight vac. so when you step on the gas they are always open
