Cheap effective way to raise you boost. • 2 Spend your money wisely. Posted by Alberto Alvarez on 6th Aug 2014 I am currently running the ISIS V2 mbc and the only good thing i can say about it is that it functions (barely) and only after a lot of hassle. Everything about this kit could be improved and thats why i gave it 2 stars, just not cost effective! Mounting is OK not estheticly pleasing but sturdy. Mounting screws are garbage, i stripped the threads on both and just used some self tapping screws i had laying around at home. Vaccum lines are included which is very nice. (hardly worth mentioning since most other mbc come with it) 3. Included are some brass fitting with two different angles and two plugs. (teflon tape is needed when installing these or they can leak) OK, now to the meat of the subject 4. The Boost Controller itself. Its very nice looking dial on top but there is no markings to figure out how much you are changing, not that it matters much because 99% of the time its either fully opened of fully closed. (You'll only make 10 PSI which is VERY frustrating and VERY hard to dial in) There is a TINY portion of the dial that will effectively control boost which means you cannot control boost in very small increment.ooh and before i forget the dail is backwards, turning towards the (+) turns the boost down and the (-) will turn the boost up. The bottom of the boost controller has 4 ports, only 1 of which goes to your boost source, 1 of the other 3 goes to your wastegate actuator and some don't work as well as other so. On my application i couldn't get the port with the arrow to work with the 90 degree fitting. Just save yourself some money and save up for a high end ball/spring type mbc. • 5 D1SL Sil80 ISIS VS MBC Posted by Donnie on 30th May 2012 solid device does whats needed and in car mount option is very cool! I know which one you have and you need these instructions. Im borrowing these from another website. The 'T' piece gets spliced in, arrow towards waste-gate, between vacuum source and waste-gate, the 'Controller' comes from the Black-Port on the Top of the 'T' to the Top-Port (Adjuster end) of 'Controller', and just vents to Atmosphere out the Bottom-Port. How To Install Manual Boost Controller On Rb25 240sx Swap KitThe arrows on the thing are completely wrong. After doing some research on how wastegates work and how the check valve is setup (the 'T' part). I believe the knock-off company did not actually do the research when they made the stickers. The knock-off 'T' has the spring and ball set up a different way then the 'TurboSmart' one. In the 'TurboSmart' setup the ball is against the inlet side, the knock-off is on the wastegate side. They both function the same, but use different techniques. You can check by blowing through the 'T' fitting on the top and seeing where the air comes out. The free flowing side is the wastegate side. Because it does not matter if there is a vacuum leak on the wastegate side as is does not use vacuum pressure. The idea is under vacuum the ball is pressed against the opening by the spring stopping any air from going to the wastegate or the venting boost controller. And when you have boost, the ball pushes against the spring and moves the ball out of the way allowing the airflow through to the wastgate and boost controller. 'TurboXS' used to do this with little rubber gaskets, that when under vacuum seated and sealed and under boost pushed out of the way venting boost pressure. The check valve design also makes it so depending on spring tension (like a BOV or Wastegate spring) it requires a certain amount of boost (pressure against the ball) in order to even let the boost pressure pass by to the wastgate actuator. Making it so the actuator does not creep open before your peak boost. The entire point of the check valve is to stop you from having a constant vacuum leak to atmosphere when using the Manual Boost Controller. Hooked up this way the kit works perfectly. ---NOTE--- Wastegates work exactly opposite a BOV. But do the same thing. Wastgates use boost pressure to compress a diaphragm spring rated to compress under a certain amount of load to actuate a valve. IE: When you have positive/boost pressure of 7psi-ish on your vacuum line, a 7psi rated Wastegate actuates and opens the 'Wastegate-valve' allowing exhaust gases to bypass the turbo thus creating less boost.

IE: When you have negative/vacuum pressure of 7psi-ish on your vacuum line, a 7psi rated BOV (most are more like 17psi rated springs hence the adjuster screw) actuates and opens allowing the excess boost in front of the closed throttle body to be vented without back-flowing into the turbo.
