Installation
1

• Begin, by raising the front end of your car up and placing it on jack stands.
• Disconnect the battery cables for safety.
• Drain the coolant into some kind of container that you can cover,
  so dirt will not fall in and/or animals will not drink from it.
• MAKE SURE NO PETS ARE AROUND!!!
  If dogs/cats/etc drink coolant they have a pretty good chance of dying from it!. NO JOKE..
• Loosen up your gas cap to relieve gas pressure from the fuel tank.

2

• Start disconnecting all vacuum & radiator hoses/lines from the intake manifold
  using the long needlenose pliers (real handy).
• Disconnect sensor plugs, injector plugs (use a pick), etc., from the intake manifold and throttlebody.
• Take the 12mm socket + ratchet and loosen up the fuel filter pressure-release bolt.
  Some fuel will come out, so have a rag handy.

3

• Using a 10mm socket, remove the black plastic wire harness cover from the fuel rail.
• Remove the vaccum hoses from the FPR (fuel pressure regulator).
• Using the 10mm socket again, carefully remove the nuts that hold the fuel rail down to the intake manifold. These small screws tend to fall behind the engine easily (i hate when that happens), so be careful!
• Carefully wiggle the fuel rail off. The injectors will probably come off along w/the rail. Try not to damage/rip the rubber o-rings that are on the injectors. Also, try to not lose the round black grommets that hold the injectors in place.
• Place the fuel rail w/injectors still attached to it, somewhere out of the way, even though the rail is still connected to the fuel filter line. Just get it outta the way, near the battery somewhere.

4[Underside Manifold Bracket Removal]

• Next, are the 12mm intake manifold flange nuts & intake manifold underside-bracket (if applicable).
• If this is a first-time-removal of your GSR's intake manifold, you're in for a real treat! (see frustration not @ bottom)
• Get under your car so you can see the underside of the GSR manifold & underside-bracket.
• Use the ratchet with a lengthly extention to reach the two 12mm bolts seen in pics 1-3 below.
• Taking this bracket off, will make the swap waaaay easier.
• While you're under the car, disconnect any sensors that are still connected to the GSR manifold, such as the IAB sensor (black-round canister mounted on the underside of the GSR manifold)...
• Now, loosen up and remove all of the 12mm flange nuts that are holding the GSR manifold to the head.

5[Swapping of Parts]

• Once you're finished removing all 12mm flange nuts, double check that all sensors, vaccum lines, and any coolant lines are not connected to the manifold.
• If everything looks go-to-go, carefully remove the GSR manifold. (PIC 4).
• Using a 12mm socket, remove the TB from the GSR manifold and carefully peel the TB gasket off using a razor blade to help.
• Next, you will prep the Skunk2 manifold, by swapping over the GSR's fuel rail + TB mounting posts and required sensors.
• You can start off by removing the GSR's fuel rail mounting posts using two of the 10mm fuel rail nuts.. (PIC 5)
• Next are the throttlebody posts.
  Remove & apply these posts using the same technique as used on the fuel rail posts.
• Next are the sensors...
  Swap over the IAT and IACV sensors. (PIC 6+7)
  Then, apply the ITR throttle cable bracket. (PIC 8)
  Lastly, swap over the rubber fuel injector grommets onto the Skunk2 manifold. (PIC 9)

6[Throttle Pulley Swap]

• Now that you're temporarily done fussing w/ either manifold, it's time for throttlebody (TB) adventures!
• I'm assuming you've acquired a non-GSR throttle pulley. If you haven't done so, get one! (PIC 10).
  TIP: almost any 88-01 civic/integra (non-94-01 GSR TB) throttle pulley will work on the GSR TB.
• Use a 10mm socket to remove the GSR TB pulley, and swap over the non-GSR TB pulley. You *might* have to fiddle w/remounting the retensioning spring a bit, but its not hard to figure out.
• Next, remove the GSR throttle cable bracket thats on the TB, as well. (PIC 11).
• That was easy wasn't it? (yes). If you'd like to, you can now mount the TB onto the Skunk2 manifold, reusing your GSR TB gasket (if you haven't fully damaged it).
• Now, go install the Type-R throttle cable. It's pretty straight forward, so I'm not including the how-to on this.

7[Prepping the PCV Valve]

• Go back to your engine bay, and take a look at the area where that bloody intake manifold underside-bracket is.
  You should see the factory oil catch can with 2 lines plugged into the topside.
  This is where the PCV valve lives. (PIC 12)
• Once you've pulled out the PCV valve, get a lenghtly vaccum or coolant tube and attatch to the PCV valve. Then plug the PCV valve back into its respective location for test fitting. (PIC 13)
• Now, take the Skunk2 manifold, place it on the head, and fit the PCV tube up in between the manifold's runners till it reaches the vaccum spout in the middle of the plenum. (PIC 14).

SOB

make sure to remove those bolts in the back of the stock intake manifold first!! those are a BITCH!!!!

Can you explain why installing a Skunk2 manifold on a GSR is any different than a BLOX manifold?
On this website:
http://www.honda-tech.com/zerothread?id=1141806&page=1 there are a lot more steps involved when installing the BLOX manifold. Shouldn't they be exactly the same?

GSRTURBO

should be just the same, i mean the products the same pretty much right?
