92 hatch

Hey,
I need some help here, I've got a T25 turbo and I am doing a turbo on my civic sohc like most of you homies out there. Anyways, I'm going with a vortech 6:1 fmu and I need to know what kind of check valves I need to put in the line between my boost gauge and my map sensor intake so the CEL doesn't show up. Do you know where I can buy the 3 valves already on a line or what type of check valves I am supposed to buy?
Also, does anyone know if the O2 sensors are the same on the SI as on like the VX because I need to change mine out when I go to put the turbo on. Are all SOHC civic O2 sensors the same?
Thanks in advance for any help!

Go to any automotive store, they will have 1way check valves, or go to a pet store and go into the fish tank section to get check valves, either ones will work, also look through the forum, someone has posted several pics..

here is a homo one I have..

Sorry, but what are these check valves used for?
And why/where do people mount them
I'm lost...

check vlaves are just so the map sensor does not see any boost so it wont throw up a CEL.Many people use this instead of a missing link to save money at teh cost of apperance. Look at Jeff's paint drawing.

what about pics for a 94' civic 1.6 sohc vtec, not seeing how the pics are going to work for me, asking for pics thanks

they work the same for all, do you know where your map sensor is? do you know where your tb is? if so, then you should unerstand, if not, go buy a hemls manual for your car.
