Today i whent to make my own MBC(manual Boost controller).So I whent to Home depot and got a compresor valve and some 1/4 fittings and some small hose and of we go to the mechanic to install my home made MBC that works great ,no boost spikes because the MBC has its on lock to prevent it:clap:it costed me $47 .Then we found out that my OEM By-pass valve had rust all over from like the inside and could not open so i HAD to buy a BoV (i dont like it)to solve the problem took it to the drag strip paid $10 to enter and did a 14.4 run at the 1/4 mile with 14 psi and FCD . Tonight was great I love my MR2 more than EVER :D .This car is not my daily driver is like a once a week driver.



MBC=$47
Drag entry fee=$10
Running from 15.2 - 14.4 @ 1/4 mile=Priceless

^???? if you are talking about the MBC that i made you only need a Air compressor valve and some fittings that convert the valve exits into hose entry.and some hose and conect them to the external wastegate.one side goes from the top of the wastegate and the other side to the turbine.

I got my MBC off koracing and it was garbage turst me i didn't install it wrong but when i backed the boost down as low as it could go i started spiking 21 psi :confused: keep in mind this was about 6 months old but still. so i ordered a hallman and it works great! Don't get me wrong i love KOracing products but im not crazy about their boost controllers.
