Hoping to get back onto my project in a week or so, and had a couple questions on routing the vaccum lines for boost solenoid and Tial WG. I have had my car down and apart for better part of a year, and alot of changes planned, so would like help with a few vaccum lines.

FEw changes

With EMS no KLR vaccum line
Deleted ISV


Please fill in blanks for me

Single port on rear of boost solenoid
Two front ports on front of solenoid
Top of WG
Side of WG

Thanks,

 

Search "venturi delete".

Long story short, you don't need all that junk in there.

 

OK I'l give it a shot... is this what you were asking?

and the WG connections will depend on type of WG...

LR dual port, top port to boost only signal (charge pipe) side port to EBC solenoid (line in picture)

TiAL dual port, reverse of above...

Synapse WG, depends on how you are using it... if you want it to be controlled by the solenoid... all ports with nipples to the EBC solenoid... (IIRC)

YMMV, UAYOR

 

Thanks John,

That was the refresher I needed. IIRC the boost solenoid needs boost source closest to the turbo. Does the line to the side of the WG (since Tial) need to be t-eed from the same source, or can I use one of the ports on the side of the intake that was for the ISV?

Thanks
Steve

 

Steve,

I thought you were running a MAF?

 

MAP actually, so yet another piece of the puzzle I need help sorting out.

Kind of hastily done but here is my setup.....TiAL and Vitesse MAF, with Vitesse EBS:

 

Thanks Patrick,

Basically what I am looking at doing. But w/ The ISV deleted, I figued I could run from the plenum to the side port on the Tial WG. Unless manifold pressure is differnt then the boost pipe from turbo to IC. I fiqure this would be one less T and one less Plug for useless manifold port.

+1 thanks John & Patrick,I'll be doing the same install with LR silicone hoses and it's been awhile since we tore it down.Now I'm sure we'll get it right the first time,unlike other parts of my project.

 

The pressure will be different, there is a throttle body in between the two... The isv allows some of the air in teh charge pipe to bleed into the manifold and bypass the throttle body.. even when it is there and working you have a pressure differential between the charge pipe and manifold.

The 2nd connection on the WG needs to be boost only (charge pipe) not vacuum (manifold)

 

Amazing the amount vaccumm lines and junk that will be gone from car with Fuel vapor purge system and ISV gone. Probably won't be needing the Turbo S plenum w/ the extra banjo fitting, much longer.

I guess I can tie the FPR into that plenum port for the ISV with a reducer.

Thanks again
Steve

 

Any reason you're keeping the venturi?

 

Only keeping the Venturi hard lines, The engine came with the boost solenoid in that position, although I am concerned about the engine heat. So I just left it.

I do like the metal piece to keep the hoses more organized. My car had the VD when I bought it, so really the V tube was new to me, as I had not seen it before.

The larger tube going from the AOS will continue to the Sakiou catch can. and the two smaller are going as indicated by John.
