Default Sensors from U-Pull/Pick 'n' Pull?

OK, what sensors exactly are needed for MS with all the bells and whistles? (EBC, Knock sensor, TPS, etc.) I know the GM MAP found here is found on 3.8L V6s, probably others as well. I'll double check the part numbers but I'm fairly certain they're also 3bar.

The local yard sells sensors CHEAP (because most people just steal them anyway) so what exactly do I need and what cars do they come off of?

Are you planning on running baro correction or more than 21 psi? If not, the map sensor is not needed. I grabbed the clt sensor from a camaro and the iat from a late 80's Oldsmobile. The clt sensors seem to be the same from 81-96 on GMs, where the iat has many forms. A lot of cars use a iat which is pushed into a rubber grommet, not gonna work with a turbo. The one I found screwed into a metal air box.

Dude I would go with new sensors. They're cheap new, and you are all but assured that they will function 100%. With used, there's a good chance of picking up faulty sensors, which could cause you to chase your tail looking for a problem--or worst case scenario, loose your motor.

the boost solenoid is $22 shipped new.

the intake sensor is $21 new

the knock sensor comes at a great price when you pick up knocksenseMS...

the coolant sensor and MAP sensor are not needed. Why not just buy new?

Sensors are usually $5 or free if it doesn't look important (CLT & IAT should fit this description). I'd like to run baro correction. For $5, why not? Temp sensors are easily tested with a pot of water and a multimeter. The TPS seems to be very important as well. Those aren't as cheap.

Money is money. I thought the whole idea of MS was to get standalone EFI as cheap as possible
