intake vacuum lines

[clone]

Okay got a standard 93t manifold. currently for a problem with the lack of vacuum points. have t pieced the lines going to the FPR with a small hose going to the MAP sensor the the haltech and another one going from manifold to the boost gauge and t'd to the wastegate. I need 1 more so I can now run my new intercooler piping with a BOV. have been just taped new ones on ? or should I have more then 2 true points lol ill take some photos this afternoon

take a look at mine man there are two vacum/boost seeing ports on the manifold itself there is one specfically for the BOV located to the left side of the injector wire harness brace. and one for the fpr at the other end.. if i were you even though i have tee into my fpr for boost guage i woull tee into the bov port for both the map and gauge sensors

i cant see shit in the pic with your vac lines lol

Map sensor needs a dedicated VAC supply or t'd with something that doesn't use much VAC like a boost gauge. I wouldn't ever t into the bov VAC line for a map sensor. Just drill and tap the manifold for a 1/8th brass barb. You won't even need to remove it if care full.

ive got the motor in bits at the moment anyway ill probably just take it off and tap a couple more vac lines

[sup]Jase, just grease up the tap, and tap a couple in. Its the easiest option long term.[/sup]

Yeah I've got manifold off and talk to work this week as I also need to tig a thread in the intake pipe for new intake temp sensor.


Do I know you lister ?

I'm going to weld a ally plate on this area here so that at least I'm not affecting the integrity of the manifold to much. What I'm wondering is if I have 3 brass lines coming out of where I'm about to weld the plate , will tho affect flow at all ? Ie air flow or

if your worried about it that much what about tapping them into the welsh plug at the end of the manifold.

i think your expecting to much from these line all they are is pressure reference line nothing more.

I'm just trying to make sure I never get a problem that's all. Don't want to do any more repair if I don't have to

get gsr TB with 2 vac outlets, re-drill gallaries and mod to after throttle plate... nek minnit all done

 

[Lister]

You're over thinking it Jase, placing a few holes into the manifold isn't really going to affect its structural integrity, or the flow. Just make sure they're spaced well, with some decent material between them. Unless it's a load bearing area I wouldn't be concerned.

Overkill at its finest right here !

 

[clone]

okay here if the overkill but safe lol

You might need some elbows on that.
Im not sure if there is that much room to the firewall...

 

[clone]

already measured it, ive still got about 160mm

 

[khubner1]

theres plenty. unless you choose to run a ur strut brace
