Turn up the boost on your MR2 with this Turbosmart Boost Tee manual boost controller! 

This simple ball and spring manual boost controller will get most MR2s to about 15psi. The stock 91-92 fuel cuts at 12psi, and the 93+ at 16psi. You can simply unhook the vacuum hose to the MAP sensor to disable the fuel cut.  The only adverse effect here is that the stock boost gauge will no longer work.

This installs between the wastegate and the turbo boost reference port. We include some high pressure hose to make this connection. You'll also need to cap the other port on the wastegate, or unplug the turbo VSV, blue connector under the intake manifold.
