    Extra maintenance/performance suggestions?

    So tomorrow I plan on replacing the fuel pressure regulator on my town car. To do so I have to remove the upper intake manifold. Unless there is some other way you people know of? Either way, while I'm in there i will be replacing the valve covers and their corresponding gaskets. While the upper is off, is there any extra maintenance and/or performance things i can do? From my understanding, the intake on these is the biggest choke point on these motors and the best thing to do is replace it. But i don't quite have money for that at the moment.

    Any and all suggestions welcome! Thanks in advance!

    I would replace ALL vacuum lines while you have the intake off.

      May as well do the PCV valve and screen. It's much easier with the intake off.

          all of the vac lines, the PCV stuff, and see what you can do about cleaning the upper out if its all crapped up with black junk inside. Soak it with degreaser or something while you're doing the other work and flush it out before putting it back together. Change the two small coolant hoses going to the EGR spacer too. Its 1/4 or 5/16" fuel hose, can't remember which. Nobody changes that until it pops and gets you stuck somewhere inconvenient.

            If your looking for a little more power, a HO upper intake, HO throttle body, and bored out EGR spacer is the way to go. With that said, remember these are 150hp 302's. There's only so much you can do with the stock heads and cam, but you can make a lopo run pretty good with the right combo.

            As for maintenance, as everyone else already said, may as well change all the vacuum lines, do the PCV Trio, and I hope your using Felpro Permadry's for the valve cover gaskets.

              oh, if the lower intake is leaking oil from the back, now would be the time to change that too. change the oil if you remove the intake. I blew a motor up once by trying to put that off. It gave me about 50 miles before wiping out the bearings.

                You can find a used HO upper and TB on craigslist, Mustang guys practically give away the stock stuff, or call around if you have any shops that specialize in Mustangs and ask if they have any leftover factory stuff they haven't gotten rid of.

                    BTDT, luckily I was pulling into work where I had access to all the tools I needed and the boss even gave me some spare hose we had laying around.
                    Those hoses sure a PITA to get at.

                      Wow, thanks for all the quick replies! Was not expecting so many so quick! You guys are f-ing awesome!

                      I already did the PCV trio late last year when I got the car. But I will definitely be looking into new vacuum hose and EGR spacer hose. And I remember something about a grommet on the throttle assembly for the transmission, I'll have to go research that a bit and see what I can do.

                      Performance wise, I would be happy to add between thirty and fifty horse from some not too expensive mods, including exhaust. Will a HO upper and throttle body and bored spacer give me a good start? And with a well done exhaust setup ofcourse. Is this too lofty a goal for some simple add-ons?

                        I have a HO upper and can have a EGR spacer machineD POSSIBLY FOR A DICENT PRICE.

                          HO upper and throttle body helps, but exhaust also helps tremendously. If you can't get the air out, you can't get air in. I've driven stock engined cars with the HO upper, 1.7 roller rockers and good exhaust and they run noticeably better than your typical as left the factory cars. No idea what you might see on the dyno but its definitely something you can feel if you go from one to the other.

                          The throttle thing is called the TV bushing. Yes, you really want the brass one, but at a minimum you need a good one. If it fails, the transmission follows quickly.

                            It'll be hard to gain 30-50hp from a few bolt ons with the stock heads and cam...the cam is the real limiting factor....15hp-20hp is more likely...with the aforementioned 1.7rr's, HO intake/TB/bored egr spacer and exhaust...no bigger than 2.25" duals preferably and the timing bumped a little...it's not much power, but when you only have 150ish to start with, it's pretty noticable. From SO to HO, the difference in the quarter mile is about 1 to 1/2 seconds from 50-60hp.

                            Good luck,

                              the E6 heads truly do have major suckage too. Kinda why I'm hard pressed to do the HO conversion on my 88.
