throttle body and intake manifold from skunk2

hey guys i was curious on a few things before i use my hookup for these items.

i was planning on getting the skunk2 intake manifold and a skunk2 throttle body.

1. how is the fitment on the intake manifold?
2. i heard that it comes close to the firewall, will i need to remove stuff from the firewall to get it to fit correctly?
3. what throttle body size should i get? (turbo'd d16a6)
i was thinking of 70mm. not sure if this will cause any fitment or any other issues.
4. what is the stock throttle body size we have on the 91 wagon 4wd?
5. does the intake manifold and the throttle body from skunk2 move the pipe position? the pipe im mentioned here is the one that connects to the throttle body from the front which feeds air into it.


if you guys have pics of your skunk2 parts on your car i would appreciate any links or post with pics.

thanks guys.

    Definalty a tight fit. I did a little massaging when we put one in the wifes EX sedan. However once we got the mounts fixed I think it would have fit w/o beating in the firewall.

    Fitment was great. No complaints. Everything that was on teh stock manifold bolted right up...not alwys in the same place, but close enough that we didnt have to extend any wires.

    No idea on teh tb ?'s, but it does move the pipe twords teh firewall a bit. Nothing drastic though.

    All my pix of that install got deleted when I left the speedshop :(

    It's the same as the CRX Si TB.That's all I know.

    would u say i would need to redo my piping or could it still work with a little pulling?

    is it going to move it towards the fire by 1 inch or more?

    I couldnt use my civic TB with my skunk2 i had to use an integra TB. i did beat my fire wall up a bit to make things fit better but its not a bad fit.

    i noticed the intake manifold doesnt have a place for the FITV.

    what did you guys do with that problem?
  • shenrieshenrie Council Member
    I held the two intakes up against each other last night and the Skunk2 manifold is longer by the depth of the IACV, so about an inch and a half to 2" twords teh firewall. Install the IACV before you install the intake, lol.

    Shouldnt have any issues with piping, might just have to tug it a little to get it to line up like it did before.

    Please elaborate on what a FITV stands for. I heavent heard anything on the manifold called that before.

    FITV= fast idle thermal valve, only some MPFI cars had it :? anyways, mine did when i did the MPFI swap and i simply left it unplugged.
  • You guys could re-locate the IACV to a remote mount on the firewall. I did this with my D16A6 with Endyn M62 blower kit. All you'd have to do is tap the IACV air passage holes on the Skunk2 IM to take some fittings to hold some air line. It worked great on my setup. There's a special block to mount the IACV, but it's nothing too complicated to make. A couple drilled holes, and a bit of threading.

    It doesn't have to go exactly where I put it either. It can be remoted to almost anywhere under the hood. Just need to run the coolant lines, air lines and the wiring to it.

    damn, thats hawt Jaker!
  • Wow Jaker... thats an awesome set-up! How much that Endyn setup cost???
  • It was big bucks. It's going in the Wagon here in the next couple months.
  • I have both items on my EF. I'm unsure what the fitment for your intake manifold would be like, mine fits nicely with plenty of room to spare but this is on a b-series engine and an EF9 bay.

    The throttle body. WARNING : skunk2 throttle bodys are sticky. I've had a couple of issues with idle, mostly sorted now just the occational engine stall now. However, due to the stickiness it makes it a bit of a bitch to drive but you learn how to :) Mine was 65mm (dont quote me on that though), and was bored out to 68mm by a respected big name here in nz (Ronnie Lim).

    Yeah thats what I figured but I would guess better quality than a JRSC :wink:
  • I was getting 25+ lbs of boost in the hatch with it. That was a little high though. It is supposed to make around 18 psi. The problem was with the head I was using. D16Y7 stock head with stock Y7 cam just doesn't breathe well enough for a Roots blower. This new build is using a D16Z6 head with a Crower turbo cam and some mild porting.

    I had the 1st generation of Skunk2 D series IM in my hatch. I had to make a small relief dent in the firewall. I also had some issues with the heater valve plumbing and the hose fitting on manifold for the heater hose. The manifold worked well for me. I just had a few issues with the install.
  • Quick question: The Hondata insulating gaskets are a little thicker, does the studs for the IM need to be lenghtened??
  • I ran my Hondata gasket with the OEM studs for a long time and never had any trouble. Did this with the OEM manifold, the Skunk2 and the Endyn blower manifold in the pictures. It has been suggested that longer studs would be better. It only really becomes an issue if you use the insulating washers as well. They're just that little bit thicker to make the stud absolutely too short. Hondata doesn't ship the washers with the gasket anymore though.
  • Thanks Jaker, gonna use a Hondata gasket with ny Z6 head/Y8 mani and wasn't sure if I should pull the studs out before I install the head.

    innovative mount makes the intake manifold gasket. i believe they make it for all those other companies too.

    i was asking them to make me a gasket out of the same plastic material as the other IM, for the throttle body gasket.

    you guys should request it too from innovative mounts.

    I want to know how much you paid for your motor mounts first. I found a Hondata gasket for $40 new so if they could match that or go lower it might be interested. Actually I should AutoCAD a IM gasket and make it out of Nylon or something on my CNC. I'm such a slacker :(

    not sure the price.

    i didnt buy it from them cause i just found out they made it.

    i just installed the new skunk2 intake manifold. the whole thing is against the fire wall. what to do now?

    yes if you have a a6 head or 88-95 non vtec the head is a little wider. even on my y8-z6 heads it is close. i have always took a sledge hammer to the wall use a rag so the paint dosnt chip up to bad. it wont hurt anything to bang some room to fit it. TB's are any civics from 92-00 with plentium style manifolds, and any b-series motors will work. good luck 8)

    do you guys think if i get new engine mount made to move the engine forward, will there be any other complications?
    of course the engine mounts would be custom.

    such as any hoses or connections, will they have issues?

    i was thinking of moving it about 1.50 to 1.75 inches forward.

    or

    maybe move it forward about 1 inch and the rear about 1 inch up.

    this is just a thought i came up with while staring at the engine bay. i noticed that the rear had some room to come up but not the front as the center highest point might hit the hood if i raised it too much. so it would come up at a slant.
  • If you're using 4 mounts, the front of the transmission will hit the front crossmember before you get it very far forward. I think all you really need is about 1/2" further forward. Why don't you just relocate the IACV? It's not hard at all. I actually have an extra block with all the holes needed to do this. Just like the one in the picture. Your's for $40 shipped.
  • 949949 Senior Wagonist
    im still not completely understanding how this works. i can see that the block is connected to the aicv but what about the holes in the back of the engine?

    do i cover up the holes in the back of the engine?

    doesnt the aicv need the heat from the engine to regulate?

    what goes in and out of the back of the engine?

    if i understand this mod, i may be interested in your block.

    New Question:

    i noticed that when i intalled my oem throttle body with the new skunk2 intake manifold, the forth hole doesnt line up with each other.
    did anyone else have this same problem?

    also there are three long studs that hold the fuel rails on the manifold which doesnt line up either.
    what did you guys do to fix this?
    does new fuel rails from a 92 line up right ?
  • skunk manifold only uses 92-01 TB's
  • HaydzHaydz Moderator
    Yep, just grab a b-series TB and you're set.
  • JDMshuttleJDMshuttle Senior Wagonist
    look @ my old set up should have pics on here just search
  • fuel rail is also either 92-95 or 96-00 sohc's there are revisons for both. it works for 4th gen just have to update a little :wink:
