It is oriented properly for the support bracket you see by the header collector area on Y8. If you have a header or downpipe made for Y8, you should get an exhaust support brace for the Y8, it is held on under the manifold brace by the same bolts. Once it's tight, put the Y8 brace in place and tighten it to the manifold first, then tighten the bolts to the block. Hand snug the bolts up, then start torquing them properly in order. This coolant line will go to the IACV on the Y8 auto t/b, just like it did with your Y7.Ĩ) If the head is cleaned up, put your new mani-gasket on and slide the head into place. Don't put it in yet.first, remove the small hose from the water pipe right near the PCV (this one is a gusher!) Have a stretch of 1/4" hose ready (15-18") ready to put on immediately. Remove wiring clips from the manifold brace, take the brace out too.ħ) Get your new PCV valve ready by installing the 3/8" hose & clamp on it.

It's easy to scratch the head, so if you've got some chemical to soften the gasket up that would be good. This is tedious and irritating, at least for me it was. The manifold should be able to come right out now.Ħ) remove the old gasket, without gouging the surface underneath. There's one bolt on the underside of the manifold that holds the brace onto it, I think it's an 12mm. Splash! Just try not to get the coolant into the injector holes.ĥ) Using the outside-in pattern, loosen & remove the bolts holding the manifold to the head. Get some rags and cups handy, now you start unhooking coolant lines! Use some pliers or channel locks to pull the retaining clips down the hoses a bit, then start pulling the hoses off.

(If reusing Y7 injectors, install them in the Y8 rail, or just move the Y8 purge solenoid from the Y8 rail to the Y7 rail.)Ĥ) Remove all vacuum lines from the manifold to any other sources. Pull the little hose from the regulator to the manifold then lift out the rail/injectors. Loosen and remove the fuel hose nut at the fuel rail inlet.Take off the 2 nuts holding the fuel rail on, also I think the harness clips in a couple places on the rail so unhook those clips. Put the fuse back so you don't forget later.Ģ) Pull out the IAT sensor from the Y7 airbox, remove the box & piping, Also remove the little throttle cable brackets and detach the cable from the t/b and the cable stay.ģ) Put some masking tape on the injector branches and mark them 1-2-3-4 so you get them back on the right ones, then pull the plugs. When it stalls out, turn it off and remove the negative battery cable. *if you've got lots of miles and never did fuel filter, nows the time while system is depressurized also.ġ) Remove fuse to fuel pump, then start car. *you might want to change PCV valve while manifold is off, it's not easy to get to otherwise. Premixed coolant for aluminum blocks (you're going to lose some!) hose, suitable for fuel/vapor/coolant use.Ībout 2ft of 3/8" i.d. Here are things to have on hand when you start the project, so you won't have to leave for the auto parts store during the middle of it:Ībout 5ft of 1/4" i.d.

Here's a rundown on how to do it, this is everything I can remember off the top of my head.sorry if it's long-winded! If you use the Y8 injectors with the Y7 ecu, you will run rich though so you want to reuse your Y7 rail & injectors.

Of course the 5-speed manifold setup works fine too, you just need to block off the IACV opening on the back and swap the throttle rotor & spring over to your Y7 t/b. If you plan to keep the Y7 computer, it's easiest to use a Y8 auto manifold and t/b since the IACV setup is the same.
