Custom Turbo kit

Im planning of making a custom turbo kit for my civic im going to get a 14b turbo or a turbo off an 1g eclipse, im trying see if i can use the 450cc injectors from the 1g eclipse, also the 1g bov, the SMIC, and if missing anything please tell me...

yep, you can use them. Here is a good right up http://www.cse.uconn.edu/~yelevich/turbo/turbo.html, it almost list everything that you need for a begining turbo project and also check the www.homemadeturbo.com especially the turbo project section.
Good luck
