I got a 94 civic HB DX with a Vtec head its turbo. As it says in the topic i hit a pothole and all of a sudden no more boost. The turbine spins in the turbo housing but my guage shows no boost pressure ... also its back firing all the time what do you guys think would cause this sudden change.

you knocked piping loose,
or that would be too obvious

i didnt lift the car in the air but i took a look and everthing in the attached to the intercooler seems to be tip top as far as other piping i couldnt see anything noticeably wrong with it .

You knocked a charge pipe loose. I'm willing to put money on that. Double-check all your couplings from the compressor housing to your manifold.

As weird as it is, I agree with him. It's probably loose and you're losing air through the coupler on the IC or something.

or the intercooler broke j/k its prolly a coupler like eran said.

Oh ****, I almost forgot about this topic I made. My buddy bought a turbo'd car, well, read the thread. Its great

Long story short, it probably ripped a gap in the exhaust manifold.

No boost pressure and backfiring are both symptoms of a boost leak, ie. charge pipes have blown off or possibly in the jostle you tore a coupler.

Get a pressure tester (or make one). Hook it up to your chargepipes and pump it up. If there is a leak you'll be able to hear and detect it a lot better with the car off. But it does sound like a boost leak.

i love that the people who can afford turbos dont know much about em.

im sure you knocked something loose man. though it may not appear loose, jack the car up and check it out

this would be the downside to bought, not built

i found the problem it appears that one or of the screws that bolt the exhaust manifold to the exhaust broke off in the impact so im gonna get up under the car later and see what i can do to fix it .... thanx for the help guys
