NGK Iridium spark plugs help restore throttle response and gas mileage in Dodge Dart with 2.0/2.4L engines

Looking to get back some of the crisp throttle response your Dodge Dart / Jeep Renegade / Jeep Compass / Jeep Cherokee / Fiat 500X /2015-2016 Chrysler 200 / or Ram Promaster with 2.4 liter engine had?

We tested out a set of these new NGK iridium spark plugs in our 2014 Dodge Dart with 2.4 engine and were impressed with the improved throttle response afterwards.

Charles worked/restored another 97 Neon with 2.4 swap.

Our employee Charles bought a 97 Neon Expresso coupe from a local friend of ours.

This car was originally from San Antonio, and built with a 2001/2002 PT Cruiser 2.4 engine with 2.0 Neon cams.

This car is built with stock internals, stock header and exhaust but is using the MPx power steering bracket, its got AC as well. One thing you have to know about using 2.4’s from the PT Cruiser if you are swapping into the 95-99 Neon , will be shown below.

The Dodge Neon 2.0 bolt pattern for the intake and exhaust manifold is different than the PT Cruiser and SRT-4. So because we are using a 2.0 intake manifold on a PT head, the bolt pattern had to be redrilled on the head and manifold. See below.

plus lots more mods

We’ve followed Mack’s car for a few years and seen it transform from a first gen Neon with SRT-4 swap, then he swapped in a stage 3 Mopar turbo kit, and now this twin scroll manifold and Zeta 3.0 turbo. Its progressively gone from 240 wheel horsepower to 400hp and beyond!

Onto the pictures. We hope you appreciate all the fine work Mack has done!

Here is a walk around and idle video!

Bolts that secure the intermediate shaft on 2003-2005 Dodge SRT-4 to engine

We had a customer ask about the size of the bolts that hold the intermediate shaft to the support bracket on the 2003-2005 Dodge SRT-4.

There are two bolts that secure the intermediate shaft to the support bracket.
Intermediate shaft to bracket M8x1.25×20 (2 pieces)

There are two bolts that secure the aluminum bracket to the engine that the intermediate shaft bolts to.
Aluminum bracket to engine M10x1.5×25 (2 pieces)

Hope this could be of use to someone out there.

First gen 95-99 Neon vs Second gen 00-05 Neon fuel pump assemblies – compatible, but not really

We wanted to share information on the 95-99 and 00-05 Neon fuel pump assemblies.
They are essentially the same, and can be interchanged, however there is one big issue that makes them not really suitable to be swapped.

The design of the fuel level sensor is designed differently, and what this means, is that if you install a second gen fuel pump in your first gen, the pump will work fine, however the fuel gauge will display backwards. So if you have a full tank, it will show your car is empty. The same thing applies to the second gens, if you install a first gen fuel pump assembly it will show opposite fuel level as well.

12.5:1 2.4 JE custom pistons VS OEM pistons for Dodge/Plymouth Neon 2.4 engine swaps

We thought we’d share some weights and photos of the OEM pistons vs our new custom made JE 12.5:1compression pistons.

These pistons are designed for use in the 1995-2001 EDZ motor out of the Dodge Stratus, Breeze, Caravan, and PT Cruiser that 1995-1999 Neon guys commonly swap into their cars. This swap is also done in the 2000-2002 Neon, the 03-05 Neon uses a different computer that is not compatible with this engine.

In the photos below, we are showing you the weights of the stock piston vs our custom JE piston.

Stock piston: 9.4:1
Pressed in wrist pin, and Full face/skirt design

JE custom piston: 12.5:1

Floating wrist pin, Asymmetric reduced skirt design

Difference between the stock and aftermarket pistons? The aftermarket JE pistons are about 4% heavier, HOWEVER, they have a reduced piston skirt design that reduces drag, and the JE pistons use a floating wrist pin that reduces drag on the piston and rod when the piston is rotating in the block bore.

To find out more about the pistons we offer for the EDZ 2.4 motor, please visit our 2.4 swap section of engine parts.

AutoMeter gauges not being set at O when turned off/Or needing Calibration

There are two scenarios in which you’ll have a AutoMeter gauge thats not accurate or is not set to zero when the car is turned off.

1) You received a brand new Autometer gauge
2) You’ve had a gauge for a while and it is inaccurate, or it shows -5 or +4 when the car is turned off

Now, if you have a brand new gauge, Autometer frequently ships the gauge with a locking pin in the back of the gauge that needs to be removed and the gauge will be good.

Now if you have installed the gauge and it was fine, but then its now inaccurate, you will need to send it to Autometer for calibration. Auto Meter

First gen Neon NA trick – seperating the lower water neck from the intake manifold

The first gen 1995-1999 Neon DOHC has an intake manifold that is cast as one piece with the thermostat water neck. Early 95 SOHC manifolds have aluminum manifolds as well but most 96-05 Neons with SOHC engines have a plastic manifold.

What this does, is transfers a lot of heat from the coolant that is typically 170-220 degrees into the intake manifold that is normally about 80-130 degrees. This causes the number one runner to absorb lots of heat and warm up the incoming air going into the motor more than we’d desire. One trick you can do, is to cut the water neck off the intake manifold and then weld a plate onto the water neck as you’ll cut into the water passage. You should carefully plan on the cut so that you can reuse the two lower bolts on the bottom and one of the upper bolts. We cut the lower bolt in half so that one bolt will secure the water neck and the intake manifold simultaneously.


Alex’s old 98 Neon ACR with 2.4 swap is coming along great!

Around mid 2017 we bought Alex Lopez’s 1998 Plymouth Neon ACR.

Since we bought the car, we have swapped to the AMM manifold, put on a longer throttle cable and went from a 60mm throttle body to a 55 for better driveability, installed a custom second gen power steering system, did some cleaning up under the hood, and installed a hood lift kit. Sorry for the dark pictures, but check out how great its looking!

Second gen power steering and AC system with automatic belt tensioner system installed on 1998 Dodge Neon ACR with 2.4 swap.

Progress! We recently bought Alex Lopez’s 1998 Neon with 2.4 Swap. It came with a built motor but no power steering and we wanted power steering. So, we gave it some thought and decided to go ahead and figure out a way to install the automatic belt tensioner system and second gen power steering pump and reservoir. We really like how the second gen power steering system has the reservoir built in, which allows for more room behind the motor, and no power steering lines running back and forth around the cam gears to the reservoir.

Our goal is to later offer the necessary brackets for you to be able to install the second gen pump and reservoir in your first gen.

So, here is our first startup video. You’ll hear a high pitch vacuum leak, this is from the throttle body, please disregard that noise and just check out the sweetness of the power steering on our high compression 2.4 swap.

Next up we are going to be putting in a lightweight and smaller battery to make room for the air intake system.
