I have a D15B7 engine in my Civic, I bought it as a project car and took the head off to replace the head gasket and inspect the cylinders. I got a Skunk2 Pro Series with the vehicle when I bought it so I decided to put it on while I was at it. The issue I'm having now is that the stock injectors and o rings fit fine in the stock intake manifold, but they are way too tight of a fit in the pro series intake. They won't go in even a bit and I don't want to risk breaking anything by forcing them in. What do you guys suggest I should do?

can you post some pics? from what i know d and b series basically uses the same injectors.
it’s really weird for the rubber isolators/dampers not fit on the manifold.

where did you buy your skunk2 manifold from?
i have a skunk2 pro series manifold on my b16 and i didnt have any issues.

 

Hi kmv, thanks for the reply.

I got the manifold with the car when I bought it. The seller said he'd planned on putting it on in the future but couldn't get to it yet, the whole vehicle is in rough shape. It could be a Chinese knockoff, but I don't see any differences when comparing it to the real one.

The injectors slide into the stock manifold, but they are visibly too big for this one and won't go in. I haven't done a fuel injector replacement before, so maybe these are just a tight fit, and my stock intake injector ports are worn down.
These don't go in even a bit, and from the videos I've seen, they're supposed to slide in at least a bit before bolting it down the rest of the way.

Your issues are not a common problem for this product. So, either you are doing something wrong during installation OR there is a specific issue with your manifold. Members of this Forum cannot see what you have, so you are going to have to take some initiative, use some logic, and start MEASURING parts to see WHY this installation doesn't work. Stop "Bumping" this thread hoping for some magic answer... it won't come.

The irony of all that you are going through is that this intake manifold change will do ABSOLUTELY NOTHING for you from a performance standpoint... so, when you are all done with this head-ache, all you will have gained is a great feeling of accomplishment and a nicer looking intake manifold. I hope that is enough.

 

Okay, thanks.

I plan on modifying this engine further in the future, I already had the intake which is why I decided to install it

 

by the way guys his car is turbo

It took a little bit of force but theyre in now and torqued to spec 👍

I think they were difficult to put in because of how cold it is where I am

 

Sometimes it just takes a little extra effort. Well done.

 

Should always use a little O ring Fuel grease so you don't pinch the seals with a dry insert.
