I have a Civic Si, but I'm buying an ITR manifold to use with RC440 injectors. For those using RC440s in your ITR, what lower seals do you use to maintain proper depth and correct spray pattern in the manifold? I bought some seals a while ago to use with DSMs I have. They are part# 16472-PH7-003. They're supposed to have been for a '95 LS Integra, but I searched on the internet and the only info I could find is that they are used in an NSX. Can these be used? If anyone can offer advice, I'd appreciate it.

 

i didnt change any seals when I installed my 440s...whatever came with them is what I used. I have since put in 370s and did the same.

 

Thanks man, I'll get the type r seals then.

 

How far is the lower seal supposed to be on the injector? I got the lucas 440 injectors and thought the seal that I got from auto store was too small cause it didnt go all the way up the lip of the injector. So I bought rc injector seals and its basically the same thing

 

just use the seals that came with the car. thats what i did

 

Stock is same, So is the seal supposed to go all the way up the injector cause if I do that it wont fit in the manifold DUH

 

how far up is it supppposed to go?

 

anyone?>

 

TurboTeG4 : pretty sure that's fine, there's a gap between the upper rim of the injectors and the seal in my car. As long as no fuel leaks when you pressurize the system you should be fine
