eliminated boost solenoid after installed mbc?

[aucerumo]

hi, do u guys eliminated boost solenoid after install manual boost controller on stock sr20det? this is my stock vacume set up before installed mbc. little vacume hose from air intake to boost solenoid, boost solenoid to T, one to t25 turbo wastegate and other one to cold air pipe from intercooler. if i remember it right.

yes, you would not need the boost solenoid after you install a MBC or EBC.

You can actually run a direct line from the turbo compressor outlet (you have to make a nipple) and to the wastegate actuator and it will still run 7~8 psi.

where is the factory boost solenoid??? a pic would be nice LOL

Running the boost control solenoid properly runs the SR at about 12-13psi.

i wouldnt mind a pic, anyone?

Running the boost control solenoid properly runs the SR at about 12-13psi.

so that means that the 205hp rating on the engines is on 12-13 psi?

I'd love to provide a pic but I haven't had the boost solenoid on my car at all since I swapped in the sr. It's not needed.

The 205 hp figure is at the flywheel on 7 or 8 psi. If your running a stock boost solenoid and your car runs 12-13 psi, it's not working.

Actually it is running properly at 13psi. People running 7 just short change themselves.

The SR came with the boost control solenoid for a reason. If the SR's in the US without boost control solenoids run 7 psi normally, then why would Nissan put in a pressure controller to keep it at 7?

Nobody who has hooked up the stock boost control solenoid and was not throwing any ECU codes has stayed at 7 lbs. 7 lbs was probably started by heavy throttle since they probably did not hook it up on their first SR swaps. Then they made that FAQ which basically turned into a bible for SR's.
