ok i know nothing about trubos yet, so i have some questions that you all may find dumb.

what all do i need to trubo my 90 integra?{i have a b18b with an obd1 convertion}
a turbo(of course) but what do i want?(i want about 10 psi more maybe)

intercooler?
custom manifold?
now see i'm stuck, i really know nothing about this stuff.
also i would like to know how muct the parts i will be needing are gonna cost me (in usd)

 

Read up for a long time and get everything figured out before starting or you WILL run into problems.. Trust me lol

 

Start by reading everything you can. Then order one part at a time. Do research and find out what part is going to be best for your application and what price range you have to stay in. There are 10,000,000 little stupid things you will need to turbo your car. Start with the main parts and work your way down to the small stuff.

Go to the FAQ bro...It has everything.

 

ok i read FAQ and it helped some.

now i stil have a few more questions, if you don't mind

ok so i found a turbo very cheap it's from a ford/mazda 2.2turbo. It is a whole car and i know the turbo work.

me question is whould i need to buy any other parts, other then some hoses, brass T , and maybe Engine Management of some kind. I already have the boost gague, and a/f gague.

and i need to make a custom manifold and down pipe right?

also i was told this turbos are around 8 psi, is that right?

 

The turbo from the Mazda should be just fine. If I remember correctly others have used those too. As far as parts, you'll need:
Oil feed line
Oil return fitting for oil pan
brass tee(1/8in npt thread to?)for oil out of block
will probably need manifold and d-pipe built
injectors(450 dsm)
AFC

That's some of the bigger stuff. Hope that helps a little.
