I am going to be installing a boost gauge on my FD and I was looking over the install guides here on the forum and everyone uses the top nipple on the intake, the one closest to the firewall. Mine already has a line connected to it. I know I could tee into it but there is a nipple right next to it and I was wondering if I could use that. I dont believe there would be a difference but I just wanna be sure.

 

What is in that nipple now? The forward nipple is usually routed to the primary turbo's blow off valve.

You can use either nipple though. Same thing basically.

 

It is routed to the BOV i believe. I was just double checkin. Thanks.

 

The only potential mistake would be to 'T' into the vacuum line going to the Boost Sensor. I've seen that done, but recommend you don't do it.

 

Been doing it for 12 years, no issues.

 

It won't hurt anything, but why do that when there are other options availble without adding potential points of failure for the boost sensor? I guess if you have quality vacuum lines and zip-tied connections that's not likely. But it can scare the beegesus out of you if it gets loose, since the car will suddenly run like crap. I know it scared me.

 

Why? Less line to run. The boost sensor line is right there instead of running a longer line all the way around to the far side of the UIM (since most people are using mechanical gauges and running it into the cockpit on the LHD side). Having a 'T' on it doesn't make it any more likely to fall off.

 

lol, it does if your clumsy fat hand knocks it off during an oil filter change and you didn't notice until you start the car.
Though I was using kind of a cheezy 'T' fitting. Lesson learned as far as I was concerned.
