The blowoff valve on the Toyota Supra is fairly simple to install. You will need the following items..
1. Tools
2. Toyota Supra manual and repair guide
Now, read through manual until you find the spot where it says how to "install the blowoff valve".
Next, and this is important. READ that part carefully.
After reading the manual, decide what tools you are going to use. Personally, I have a preference for wrenches, pliers, and ladders.
Use your tools (see list item 1)and begin repairs.
Thanks and good luck.
for a 86-1/2 to 92 supra, the expansion valve is located in the evaporator case. mike b.
There isn't one
you can adjust it via the idle control valve.
At the front of the car by the front left wheel, if you can get under there you should see it, you don't even have to pop the bonnet
its right beside the wiper switch

The Vehicle does not have a blow off valve. so you will never find it.
yes you can, just replace the stock diverter valve and throw the bov in there

A4's have no blowoff valve. VW's and Audi's use a completely different setup.
