I was psyched to find a complete Charger/Magnum 2.7 intake and the exhaust manifolds on eGay for cheap. Its great when someone doesn't list an item correctly.
For those who wondered if the Charger intake would fit under the hood, it doesn't. But it will with a little help.
For those who wondered if the Charger exhaust manifolds will fit, they will. Of course you'll need to modify the down pipes. (They will definitely require moving or deleting the stock cats)
I have my engine, and car, ripped apart for the normal high mileage maintenance.
- timing chain
- water pump
- valve seals
- oil pan gasket
- front brakes
- front bushings
- front struts
- front bearings
- sub frame bushings
- and the cooling fans burned up
I'm also doing the exhaust while its apart. True 2 1/4" duals through a homemade muffler and Flowtech Purple Hornies in the back. O2s, plugs, coil boots, thermostat, ect. May replace the oil pump.
The original tie-rod ends and ball-joints are still in great shape. I'm not replacing factory joints if they are still good. The original cv shafts are still fine too. I just had one apart last summer for a ripped boot and it looked great yet.
Back to the intake and exhaust. I'm not looking to make more power. It is a 2.7. But if I can make it more drivable and get some more gas mileage out of it... Plus the exhaust will definitely sound unique.
The exhaust is self explanatory. Look at the stock log manifold. It has a tight u-turn in it. The charger manifolds are a real tri-y style. They flow much more smoothly out of the head and down to the collector. I'm also taking out my burned up cats. I'll put one on later. That'll free up a lot of restriction in the exhaust.
The intake, well, its crap. Its designed for high rpm flow. How often are you driving around at 4k rpm or higher? The charger intake has really long sweeping runners. This allows more low end flow when you hit the gas. The log chamber with a long run from the throttle body will also aid in low end. The reason Chargers have "less power" is because of the intake they use. They basically took away from the peak hp, and gave the engine a broader torque band. So this makes the car more drive-able.
Few issues you run into with the intake. First, the butterfly valve on the end will need to be taken out. Second, the hood hits. Its not as bad as it sounds. If I chop the front of the intake and epoxy a cap on it, it should clear. The worst I have to do is slice a brace in the hood to gain more clearance. The intake also just barely touches the bottom edge of the cowl. Taking a rib off the intake and maybe a few good whacks with a block and hammer to the cowl will clear that up. The biggest issue is probably the throttle body. The charger throttle body is drive-by-wire. I'm not fitting an electric throttle into this car. I dug into my pile of throttle bodies and found an exact fit. A tb off of a '98 Ford 5.4 bolts right in place. No modifications. Its 70mm with a tps on the opposite end. It also matches the bore of the intake. I already found the stock tps and the ford one use the same values so its just replacing the connector on the stock harness.
Pics coming soon.
