DSM 1g 450cc injectors in b16a. help plz
 

Hi

i'm thinking of buying some 450cc injectors for my b16a civic ef9,

i've searched and found this thread https://www.homemadeturbo.com/tech_p...ors/index.html

what i dont understand is where do i buy the napa injector seal kit from?

i'm from uk and cant really seem to find them on internet.

it does say something about boring out the seals but which seals do i bore out?

Napa is a large automotive parts dealer. They also sell thier own brand of parts, with their own part numbers. The seal you may need is the lower one in the manifold. If yours are in good shape then you are just fine.

Bore the lower seal.

thanks for your help

anyone got the part number for the napa seals?

i've been on the napa website but it asks for part number which i dont know.

i'll have to have a look if my seals are in good shape. if not then i'll try local honda dealer and see if i can buy the lower seal in manifold

If you have autoparts stores in the UK (I dont see why you wouldnt) then seals from some other company will be fine. You dont need the Napa ones, you probably dont need any at all, the main reason to use new ones, is so that you dont screw up what you have.

The inside radius of the stock B16 seal needs to be bored out to accept the larger injector. A lot of people use the little sanding drum from a rotory tool, just a few passes should do it. Buy the injectors and and sand the insides until they fit, not that hard
