fuel rail and intake manifold

[sameintheend01]

Does an upgraded intake manifold do anything if i alraedy have a CAI?

Also, does getting an AEM fuel rail do anything if car is non-turbo and stock injectors?

yes aftermarket manifold helps alot and AEM fuel rail helps also even if your car is non-turbo.

best manifold for integra: skunk2 or JBElbrock for turbo.

Yes the intake manifold is well worth it IMO you can get a skunk2 for like $289 I think. The JGEdelbrock is a little more though but it is hella good also. The only think some ppl don't like about the skunk2 manifold is that it looks kinda like the stock one it's not polished or anything. I think I am going to go with the JG manifold b/c you can order it with a second aet of bosses for your nitrous nossles :evillaugh

the fuel rail doesnt really do anything, until you have a heavily modified engine. all it does it flow fuel, and your motor can get enough as it, with more room to expand. dont worry about spending money on the fuel rail until you are boosting or have a badass N/A motor.

thanks, that seems reasonable. What about a fuel regulator? wouldn't taht help with cai?? make a couple more hp?

Thye pressure regulator would not really help with just a CAI you need a header and catback for it to do anything really and then it isn't much. If you plan on getting nitrous in the future get the regulator it is a must have to be safe.

I have a bit of experience with intake manifold upgrades so maybe I can help you out a bit.

I bought a Skunk2 about a year ago. First off the Skunk2 is an exactly clone of the Type R intake manifold except it bolts up with the head on the GSR's engine. For some reason Honda decided to be difficult and make the bolt patterns opposite for the B18 and B16 (Type R head is based off the B16). Anyways.... It makes a lot of power. Simple as that. If you've ever been in a Type R and heard the scream of VTEC, it's the intake manifold. If you want that on a GSR then go for it.

What's different between the GSR's manifold and the Type R:

The GSR's intake manifold goes down towards the ground and has 2 runners (passages for the air to flow in). From idle to a certain RPM only the first runner is open. This runner is better for low end power, but when you get to a certain RPM (it's been a while so I forget) the second runner opens which is better for high end power. This allows the GSR to make a good amount of power in the low end while still having a pretty powerful top end too.

The Type R manifold goes up towards the hood. This presents a few problems that I will get to in the bottom of this post. It also employs a single runner design. The runners are shorter in distance so they produce more power. Now the bad part is they produce a LOT of power in the top end, but you will drop in the low end. It takes a little getting used to and kinda sucks since low end is cruisin around town power. I've heard that if you upgrade the cams you won't feel as much of a low end drop.


Now for the crappy part:

A) Since the GSR and Skunk2 intake manifolds go different directions the throttle body is in a different place. This means your intake wont line up. Way shitty. There are two things you can do. A) buy a CAI for the LS or B) Get a Type R CAI. I got a Type R CAI because it's bigger than the LS CAI. I'm not sure if that makes any dif, but oh well.

B) Since the GSR's intake manifold sits really low Honda had the throttle cable for the throttle body go up towards the hood. If you slap a Skunk2 intake manifold on there it will hit the hood. This requires you to buy the throttle cable part that attaches to the IM on the Type R. I forget what it's called, but I can get the name for you if you need it. I think it's like $10 or something. Then you need to make the cable fit around the rotor on the throttle body. It want the cable to wrap around and come out at the top, but you need it to come out on the side. It can be done.

C) Skunk2 messed up my order and didn't include directions. You can imagine how much fun this has made things

D) I'm convinced Skunk2 gave me the wrong intake manifold. I have an extra vaccum cable. If anyone could help me with that it would be great. The cable is suppost to go right next to the throttle body on the intake manifold.

E) Get new gaskets for the intake manifold and the throttle body

F) The bolts on the bottle of the GSR's manifold will make you pull your hair out. They are a pain to get out

G) The support bracket for the GSR manifold is worthless when you have the Skunk2. I took mine out. It required draining the coolant and putting a new hose in. You can leave it, or you could drop a pound (eat 1 less cheeseburger and you'll get the same weight drop when you drive your car)

H) You have to buy a little support part that holds the fuel rail into the intake manifold. Again you can get it from Acura. If you buy an AEM fuel rail you don't need it.

I) You have to be careful when you take the fuel rail and injectors out. If you remove the injectors from the rail then you need to replace the o-rings. You might want to do it anyways. They're like 50 cents a pop from Acura.


Do I like my manifold:
Yes

Do I think Skunk2 could be nicer to me since they messed up my order and still don't return my e-mails requesting an installation guide:
Totally

Would I do it again:
Now that I know how to do it right, Yes

Do I recommend you do it yourself:
No


I hope this helps

JG Edelbrock is the way to go. skunk 2 is a replica of a type r intake manifold. white trash
