Re: T3 turbo question...do i plug this? (90sedan)
its a vacuum source for the internal gate that came on that turbo origionally.
you can either get a rubber vacuum cap from the parts store or get a plug for it. its probably 1/8" NPT but might be 1/4" NPT hard to tell from the pics and hardware stores or parts store usually have them.

Re: (Flashmn)
I plugged mine with a 1/8" NPT plug, then used a vacuum source off the manifold for the WG. Boost ends up being 1/2 pis greater, and is now steady regardless of weather or heatsoak.

dont use that. unscrew and get an 1/8" npt plug from the hardware store and thread it in. Get your boost source for the wastegate from the intake manifold.

wow, first person Ive ever heard do that...
85% of turbos have the boost source for the wastegate right on the housing...
I use the pipe right off the turbo for the wastegate...

ya, factory turbos tend to use that for a boost source. it doesn't work well once you start changing ****. In the aftermarket world, flip your 85% and you're close. even if a turbo does have that port i wont use it. especially with low tech boost control. I do have limited experience, but I have setup a few boost control systems and my experience says get it from the IM and save time diagnosing problems later.

Re: (RACEPAK)
it doesnt matter really but depending on how shitty your intercooler is you might see 1-2 psi difference from what your wastegate spring is set at to what your actually seeing in the manifold due to pressure drop.
