dennis Posted October 31, 2011 Report Share Posted October 31, 2011 The SR20DET is going to get dropped in soon, just waiting on a few parts. I was following some of the vacuum charts and noticed everyone has two vacuum ports on the top of their throttle bodies. I only have one and it is below the throttle body and this is supposed to go to the wategate actuator. One of them get capped off or you can run your EAI solenoid and the other goes to the FPR. Since I only have one on the lower side of my throttle body and none on the top can I just run vacuum off of my intake manifold to my FPR? Also, doesnt the one from my wastegate actuator split off and go to my BOV as well? Next question. I have a Tomei S-Type regulator that is externally mounted. I have to run from my fuel pump to the fuel rail and then the rail to my FPR @ 3bar then back to the fuel tank? I just want to make sure I dont screw anything up when I start bending my fuel line.

Well the good new is you will be able to look at my build thread and know how I did this once you get to this point. Quote Link to comment
510T Posted October 31, 2011 Report Share Posted October 31, 2011 Correct on the fpr, plumb it on the return side. Fpr and bov need to see intake manifold pressure/ vacuum, wastegate should just get plumbed into comppressor housing to see boost only. 1 Quote Link to comment

And I can absolutely guaranty you that I will be doing exactly that!! Just picked up my CAN/AM from Icehouse over the weekend. :) Quote Link to comment

Just picked up my CAN/AM from Icehouse over the weekend. :) Yeah I was watching your wanted thread. I was going to buy one too but wiring is my thing so I just saved my money and used it elsewhere.

VoidDragon Posted November 4, 2011 Report Share Posted November 4, 2011 Can you post picsof your throttle body? Quote Link to comment
dennis Posted November 5, 2011 Author Report Share Posted November 5, 2011 Can you post picsof your throttle body? Ask and you shall receive See only one vacuum tube on the TB. I did cut off the coolant tubes coming off the TB. Quote Link to comment
VoidDragon Posted November 5, 2011 Report Share Posted November 5, 2011 Comparing that to mine (bone stock sr) looks the same. The confusion looks to be that those lines everyone has running from the top of the TB are actually on the intake manifold. So you'll haver to tap in to it somehow for vacuum. One point tho, PLMS (wish i could link atm) said to keep your waste gate line pre-TB, its not designed to work in vacuum. (which can happen on closed throttle inside the TB I imagine) I just did get my sr mounted and running myself. Quote Link to comment

FSM shows the wastegate connected to one of two tubes on the bottom of the throttle body or the intake manifold. If you look on my intake manifold on the first pic you will see two threaded holes for vacuum ports. Quote Link to comment

dennis Posted November 5, 2011 Author Report Share Posted November 5, 2011 my waste gate run's of the line on my turbo . but i have a external tial waste gate I thought the vacuum from the throttle body was the source but my eyes lied to me. It is actually off of the charge pipe. I wonder if it smart to pull it after the intercooler? It shouldnt have any pressure drop but I could be wrong. Here is a pic from the FSM for an S13 Vacuum lines. Quote Link to comment
VoidDragon Posted November 8, 2011 Report Share Posted November 8, 2011 That diagram is hard to read in some areas, I agree. I stared at out for a full day. then again the next. Lol I run my WG line pre Ic. Just because it let me keep the hose short. Less chance of...whatever. I doubt before or after Ic wil have much notable effect. Quote Link to comment
DISLEXICDIME Posted November 8, 2011 Report Share Posted November 8, 2011 Starions run it after the ic. Does your turbo housing have a flat spot you can drill and tap for a fitting? Quote Link to comment
