What must be done to add a 75 shot to a B18C1?

My friend is looking to add a 75 shot to his 93 h/b (B18C1).
The engine has a Type R exhaust cam, headers, short ram intake, and cat-back. He's about to get an AEM c/a/i for it this week as well as the Skunk2 intake manifold.

He was told by another friend that all he needs to upgrade besides the manifold is add a fuel rail. Probably going to pick up an AEM fuel rail sometime soon if needed.

Will that be about all he needs or should he look into other parts before adding the bottle?

Also, is it difficult to install the skunk2 intake manifold? From the picture I saw it looks pretty simple. He said there are a few wires attached to the manifold on now, but I think it would pretty much be unhook the existing one and add the skunk2 and just put the wires back in place like the original.

Thanks for any help on this!!

I am the one that LX98Civic is referring to. I have been thinking about adding a 50 shot or possibly even a 75 shot to my car. My friend told me that b/c I have an ITR exhaust cam, I am going to run lean. Is this true? What would I need in order to safely run nitrous? I know I'm going to have to get a fuel rail, fuel pump, and a fuel pressure regulator. My main question is: Is the ITR exhaust cam going to be a problem?

What is your e-mail address? I posted this in several forums and have some 411 on what you should do.

Most are saying no need to upgrade the fuel rail.

Anyhow, e-mail or PM me your e-mail and I'll send you the direct links to the threads.....

I'll post all the relpies here:

If it was me, I would skip the Skunk2 intake manifold and get the plate system(which only fits the GSR intake manifold).
Then just get colder plugs, retard a little timing, and since its in a civic, I'd upgrade the fuel pump(just get a GSR or ITR one).

Thats it.

Edit: I also wouldn't bother with the fuel rail either. I dont think its necessary.

Don't need that fuel rail. Also if he gets that skunk2 manifold make sure he gets an ITR Cai. The gsr won't fit that manifold. I would hope that he's already running at least a GSR fuel pump in there, if not he needs to get something bigger.

Leave the fuel rail alone. The stock are good for 300 WHP.
Upgrade the fuel pump. so that it can maintain the fuel pressure required on "boost"

he does not need to upgrade the IM.

fuel rail = garbage.

the Skunk2 mani is a bitch, but not hard if you take your time and do it right.


75 shot wet? dry? direct port? (wet would be the best for your friends application , IMO)

stock B18c1s can take a 75 shot of nitrous for quite a while before problems develop...just install it correctly.
