    Hey you can get a Summit brand 70 mm EGR spacer for like $50 or something like that. That's not too bad of a price for one really.

    Oh I will. Guaran-freaking-teed. Unfortunately I'm adding multiple power adders at once which is almost sacrilegious.

    Shorty headers, ported lower intake, 70mm MAF, 65mm throttle body with matched EGR spacer. Will be hard to tell how much each modification helped, but I'm hoping the combination of all the mods will be pretty nice.

    I think I might have found a guy relatively local to do it. Waiting to hear back.

    With all those mods going in pretty much at the same time I think you're going to have a smile from ear to ear the first time you goose it down the street! You probably just bolted on a minimum of 20+ hp so you should see be a big difference in sound and acceleration.

    So, perhaps a slight change of plans. The throttle body came off OK, along with gobs and gobs of sludge from the coolant line but the EGR spacer will not budge. At all. I'm fearful of breaking off the studs from the intake as I've heard happening so I've put it back together for the time being. I measured the throttle body and EGR spacer diameter and all are 62mm:shrug:.

    For an extra 3mm I didn't want to cause myself more problems than is worth it. So, I might just install the MAF and leave it at that.

    Now I just have to sell the Explorer throttle body...

    You can use a double nut method tighten them against one another and that will make the stud like a bolt and you can take the stud out then there will be no problem with getting her out

    Hood insulation liner installed from yesterday's junkyard trip. Not perfect, but for $5.99 you can't beat it.

    I thought about this and then read several instances of people snapping the stud off flush with the intake. The more I thought about it, the more I questioned if it was really worth it.

    It's nothing to be scared of for sure but I don't think he wants to deal with the potential headache of it just for gaining only a handful of millimeters.

    I knew my reponse would illicit this kind of response. :cool: I've got several friends that are like that; back when we were all younger they were pulling and re-building their engines, boosting them, then blowing them up a couple months later. Rinse and repeat. I don't know why but I'm not built like that. I hate breaking s*** and having to fix it, especially when I don't always have the right tools to do it.

    More power to those kinds of people though; I wish I was more like that.

    Finally have had some time at home without having to travel for work. I got the intake surfaces cleaned as best I could and got the lower intake installed last Friday. I used the trick of installing (4) bolts with the heads cut off to help guide the lower intake into place so the gaskets didn't move. Worked great!

    I got the upper installed yesterday, but didn't think to prime the fuel system before I bolted everything up and found out I had an injector leaking at the fuel rail. Looking at it some more I see that it's bent, up and towards the passenger's side slightly. This was causing the injector for #1 not to seat all the way in the fuel rail since everything wasn't lined up. So....I took the upper back off and spent this morning convincing the passenger side fuel rail to bend back to it's original form, or close, and get the injector to seat properly. I went ahead and replaced the upper o-rings on the passenger side injectors since I kept pulling them in and out of the fuel rail.

    All the major components bolted back up; fuel rails (properly now), upper intake manifold, wiring harnesses, connectors/plugs, etc. Still have some miscellaneous items like the distributor boot and 5.0 intake plate, but functionally it works. Car ran for about 5 minutes this afternoon; no leaks except where the hose connects to the heater tube from the EGR spacer. Just need to tighten the clamp a bit more I think.

    Lastly, with the fan removed I swapped on a set of underdrive pulleys for the crank and water pump. The lip of my existing crank pulley was bent so I figured why not get UDP's.

    Finally finished wiring up the new fan this morning, and got the fan itself installed with the shroud. I had a good 1/4"-1/2" clearance between the fan motor and the water pump pulley; that was after the dremmeled out part of the cover that went over the fan motor.

    [​IMG]

    After I got the top of the fan bolted to the radiator the bottom was still loose and could move a little bit. I fabbed up some L-shaped brackets that I could attach to the lower radiator support and then they have a rolled edge that rests against the fan shroud and prevents it from moving. With all that clearance between the WP pulley and fan motor :D I wanted to make sure the fan didn't move.

    I tucked the FAL controller underneath the bird's nest of wires by the starter solenoid and coil. The 40A fuse is mounted to the bottom of the battery tray in between the battery and the washer reservoir. Anyone have a coil cover laying around they're not using?:cool:

    With that, the engine bay should be completed. What's that you say, it looks stock? Thank you very much. I even found the underhood light in working order.
