i just finished installing my turbo on my 95 dx and when i tach it up i dont get any boost. my turbo is .63 on the hot side and .50 on the compressor side. i was told i wont see any boost unless i was actually driving the since it is a big turbo for a small motor. can anyone tell me if this is true.

you can't see boost at idle. Or when there is no resistance on the tires, meaning you can't just jack it up and put it through the gears and expect to see boost.

you won't see boost on any turbo unless the car is moving actually.

if there is pressure in the lines, maybe. It all depends on how good of vaccum you're getting at the time.

no, thats a good location for it. You won't get any better unless you run a vacuum manifold. Which will run off the brake booster.

Just wondering, do you have an external waste gate or internal? Just tryin to help out before you come back saying you can't boost even while moving.

so, the waste gate won't open? Get a pic man. What kinda waste gate? Tial? Please don't say ss autochrome or xs power. If it is ss or xs chances are its not even gonna work. If its tial or something of that style, make sure the vac line is going to the bottom fitting for vacuum and not the top. The top is for a boost controller.
