I pulled an intake manifold from a '90 Lebaron and a 52mm throttle body off a '92 New Yorker for my '92 Lebaron this week. Will be taking my time porting and polishing per the Kelly-Mulhern website guide.neon98rt said:i put a custom intake on mine
ported and polished the intake manifold
got a matched set of injectors
bigger exhaust high flow cat.
i notice a difference.
they all flow the same. Most auto part store have an injector cleaner and they can tell you if you have a weak one. I bought a set that was matched already.Ser Creighton Longbough said:I pulled an intake manifold from a '90 Lebaron and a 52mm throttle body off a '92 New Yorker for my '92 Lebaron this week.

Plan on running a cone-type intake somewhere under the hood.
When you say "matched set of injectors, what do you mean?
Sure thing.neon98rt said:they all flow the same. Most auto part store have an injector cleaner and they can tell you if you have a weak one. I bought a set that was matched already.
can you link that website for me?
I like the "somewhere" part about the intake. There isnt much room and putting it behind the battery in the heat is counterproductive. The battery in the trunk is the best way. Expensive set up since wire cost a lot now and you will need a sealed battery.
can i get a job where you work. it sounds like you make a lot of money. I am more on the 100 dollar mod or homemade mod side. I am looking through the trash now for a piece of plastic to block the hot air from getting too easily to the filter... lolJerry Simcik said:Evidently the supercharger from the GM 3.8L and some Fords of the same vintage can be made to fit on that intake with the use of an aluminum or steel adapter plate. That or a turbo would give you a bigger performance boost.
Furthermore, this 6G7X family of engines come in various sizes, and most can be interchanged rather easily. The 3.5L (6G75, I believe.) is pretty potent, as are the newer versions of the 3.0L. The problem with going to a newer setup are the computer controls. The way around this is to basically do a long block swap, but you may not get the full potential out of the swap, as the electronics could limit you.
There is a 3.8L available in this engine family as well, the latest and greatest is still in use. It's now called the MiVEC engine... It's pretty potent, but it would not be a direct swap. In fact, even the older 3.8L is harder to swap. But, a newer, higher compression 3.0L and/or a 3.5L could be swapped easily for a nice power gain. The 3.5L has quite a bit of low end torque...
thanks. i will look for some aluminum sheets.Jerry Simcik said:Haha - I don't make that much. When I did the engine swap, I found a 3,000 mile 3.0L out of a 2005 Eclipse GTS for only $600. Did the work myself...
And as far as blocking hot air for the intake, try a piece of tin or sheet metal. If you really want to be fancy, do this, then use some thermal insulation (like you find for use in car door panels, floors, etc.) on top of that.
Yeah, that's what I figured; I just posted those pics up for a visual 'concept'.....aaand the fact that I have a V6 Fusion (3.0) as my DD, and have the one in the second pic installed in mine.I will have to make mine. I dont think i will find a box pre made that will fit. I got the metal the other day. My idea is to get the fresh air that comes from the holes by the headlight and up from the road and to block off any from the sides. I already have a tube bringing fresh air from the front of the car close to the air filter. Even after a long drive with my new " ram air" the filter is not even warm to the touch. I keep forgetting to put a thermometer there.
I added the heat shield. You cant see that it goes down the side of the radiator too. It actually works way better than i expected. i put one of those indoor out door thermometers on my filter . The temp under the shield is the same as the outside. If i let the hot engine sit the temp goes up but quickly goes back down to the outside temp. I do have an air scoop that goes from the car air dam to inside the box. Maybe i should plug that and see what happens. I wonder if i can run this in the winter? Is there such a thing as too cold of air?
How low is the air filter, in relation to the road? As far as "too cold" of air temp, I don't think so, but I really don't know; but we've all seen snorkels on jeeps, and other cars where people have removed the low fog lights and having the intake begin there......so I don't think you can go too cold....unless maybe you're north of the arctic circle, and winter lasts six months.
As long as you're not low enough to have water getting sucked in while driving in the rain, I think you'll be ok.
