I think the best *** for me is to just redo all the vac lines.

I am running a PFI Turbo kit with a FMU, MEVI, Greddy Emanage with Profec e-01, and a stock FPR.

Any help or diagrams would be appreciated.



I wonder if I can call PFI? Whats their number and website?
edit: I found that out and talked to Bill.

I am thinking my boost sensor may be bad? The vac gauge reads -15, while the E-01 says -5.

I also emailed Nigel.
I am sure he has emailed others the diagrams though?


http://www.mohdparts.com/emanage/ has good diagrams of the boost sensor and wastegate. I am thinking redoing everything may fix my issues.
I may need to confirm I am using the right ports on the WG etc.

Please share what the ideal setup would be and what best sourses to use for the vacuum.

Any recommendations are greatly appreciated.

Please help. I want to be able to tell the transmission guy over the phone (or fax) how it should be going. I will not have the opportunity to go out to the shop and do it myself at this point.

I know Nigel is out of the country, but I was hoping he may have some diagrams handy on a laptop or something.

 

The readings are probably in two different measurements. My boost gauge reads in Hkpa, wich is pretty standard. A normal vacuum gauge reads in in-hg. But 15 is a little low, should be closer to 20 in-hg. My boost gauge usually reads between -6.0-.7.0 at idle.

Also, try not to tap into a single vacuum line too many times, it is possible to get a false vacuum signal that way. For myself, the wastegate and FMU have there own line since if they get a bad vacuum signal then it could be disasterous. The boost gauge and BOV are not as important and can share a vacuum source. My vacuum sources include the line comming off the FPR, two off the vacuum hoses comming off the TB, and I also had some unused vacuum hardlines after my motor swap so I am using those instead of capping them off.

 

That is a good thought. I know the E-01 reads PSI in boost, but I guess I dunno what the vacuum is reading in. I really doubt the sensor is bad.

The FPR vac line is split like 5 ways to the FMU, boost sensor, MEVI, profec solnoid IIRC.

I believe the wastegate is on a seperate line, I forget, I am wanting to just redo it all. I wonder what source would be best for the WG and BOV? So pick a line under the TB for those?

I really wish I could fax the shop what I want. The tranny shop installed my MEVI awhile back, so I feel they are familiar with how the vac lines on that went. They are asking me for instructions/diagrams of how I want the vac lines ran with the turbo kit.
They used a diagram that Jay hand drew for my MEVI/SArd fpr install.


I kinda wish we would have left my sard FPR installed. During the turbo install we took my SARD FPR out and installed the stock fpr with a FMU. We were running out of time, so I think that is why.

 

There are tons of vacuum lines to choose from. I would do no more than two off the FPR, then there is one right off the Manifold, between the IAVC and TB. Mine is a bit different because it's an I30 and my vacuum lines are not exactly like a maxima's.

 

OK thanks for the info.

What should be on the opening with arrow pointing to it on the left hand side with the 2 paralell tubes? http://www.mohdparts.com/emanage/man..._manual/11.jpg

 

That's where the vacuum line from your solenoid "out" on your boost controller goes to - it's what controls when you're WG opens.

 

hmmmm. I think nothing is going to that now........

how many things should be going in and out of the solnoid and where do they go?

 

I have the PFI set up as well and have had no problems t ing off the factory FPR with a hose 8 inches long then using a 4 way splitter then a 2 way splitter to run everything. I have the tial WG, BOV, FMU, Auto meter boost gauge, and a zeitronic boost sensor, all running off the same vac line. I tried using some of the lines from the upper intake but they never seemed to read right.
