Temporarily stopping of photo posting of Neon SRT4 swap..

For those of you following the SRT4 swap into the 95 Neon Ive got some bad news and some good news.

BAD NEWS: We’re stopping posting photos of the swap progress for a little while. Why you may ask ? Well, we have WAY WAY too many photos, and its going to take some time to organize it all, and post it.

GOOD NEWS: We’re making EXCELLENT progress with the swap car, and we’re not stopping! Just hang in there with us, we promise we’ll be posting the photos of our swap project soon.

Having shifting problems with your 95-05 Dodge/Plymouth Neon with manual transmission ?

Having shifting problems with your 95-05 Dodge/Plymouth Neon with manual transmission ?

We get calls often at Modern Performance from 1995-2005 Dodge/Plymouth Neon owners who have problems getting their manual transmission into gear, or even into reverse.

Sometimes, these problems can arise from shifter problems, but a very high percentage of Neon owners have problems with their manual transmission shift linkage bushings.

To better understand explain the problem, lets start out with the basics. Every manual transmission Neon has a shifter assembly inside the car, and two shift linkage cables attached onto it. The shift linkage cables go through the firewall and attach onto the transmission. The shift linkage cables are made out of steel, but the end of the shift linkages have rubber bushings that fail over time. Over time, your shifter will start to feel more and more mushy, and it will be more difficult to get the transmission into gear.

Heres a photo showing the shifter and the cables which are under the center console. The shifter bushings are pointed to in red, and the shift linkages are pointed to with yellow arrows.

Now, if you go to the dealership and try to buy replacement bushings, they arent sold seperately so you have to buy new shifter cables which will cost $130+! The solution to fix this, is with a product called Booger Bushings. Booger bushings are a set of four bushings that replace the two shifter bushings inside the car, and the two shifter bushings on the transmission.

Here are the Booger bushings:

Just for fun, heres a photo of a Neon where the shifter bushing disintegrated and fell off the car. This Neon still drove, but the driver would have a very hard time getting the car into gear!

MPx Underdrive pulley for 95-05 Neon, 03-05 SRT4 has been Revised/Improved!

Introducing the new VERSION2 MPx pulley for the 95-99 Neon. This pulley, is a redesign of the famous MPx pulley that has been out for the 95-99 Neon since 2001.

MPx Underdrive pulley Revision 2

This underdrive pulley creates more power over the stock pulley by reducing overall weight, and size of the crank pulley. This allows your car to rev faster, and overall be much more peppy.

We took the same measurements of our MPx pulley, machined out some material where we could to make it lighter, and then inserted a stainless steel center hub sleeve for maximum strength. The reason we switched to a stainless steel center hub was to improve the overall strength of the pulley, and to make it easier to remove.

Even though stainless steel weighs nearly 4 times the weight of aluminum for the same size, because of weight reduction and improvement in design of the pulley, we were able to increase the overall weight of the pulley by only .05 lbs, or 1/20th of a pound compared to the older design!

Swapped AC blower assembly and worked on Clutch master cylinder

Quite a bit of progress was made on the SRT4 swap into the 95 Neon in the last few days.

First off, the entire AC blower assembly was removed out of the Neon SRT4 and swapped into the 95 Neon.

Secondly, the most difficult part of this swap, figuring out how to convert the 95 Neon from a cable operated setup to a hydraulic clutch cable system was finalized.

You see, most people who do a  Neon SRT4 swap into their 95-99 Neon will keep their 95-99 Neon transmission, and cable operated system in place to keep everything simple. The problem with using the Neon transmission though, is that it isnt made to handle 250-300 foot lbs of torque. So, eventually the Neon transmission will fail.

So, in order to make the hydraulic system work, you have to either:

-Figure out a way to get the Neon SRT4 pedal system into your Neon, and make the clutch master cylinder work with it (our method)

-Weld a tab onto your Neon pedal assembly, and find a place to put your clutch master cylinder (one neon enthusiast cut up the steel around the wiper motor and placed his clutch master cylinder there, another neon enthusiast we saw who did the swap  put the clutch master cylinder in the driver side wheel well.)

-Try to figure out some sort of system that will allow you to use your Neon cable system that will somehow actuate the clutch master cylinder.

Our preferred method was to use the SRT4 pedal system, and the SRT4 clutch master cylinder. So, measurements were taken, the SRT4 pedals were installed into the Neon to test fit it and mock it up. We found that the clutch master cylinder could work if holes were cut (see photos below).

A LOT of work is ahead, but frankly, the hydraulic clutch master cylinder conversion was the one thing I was really worred about.Im glad a simple modification to the firewall was all that was needed, and I hope if this works out, that it will make it easier for other 95-99 Neon enthusiasts to use the SRT4 transmission.

The beginning of a new project – complete Neon SRT-4 drivetrain swap into a 95 Neon.

For those of you who are’nt familiar with Cory Haines’s 1995 Dodge Neon Nitro Yellow Green ACR, its quite a special, and rare Neon.

First off, the Nitro Yellow Green color was a shocking, and nasty color for most people, and most of the Nitro Yellow Green Neons produced sat on dealer lots for months, sometimes even over a year as it was too wild for most peoples tastes. It sold so poorly, that Chrysler only made 1200 of these cars. Neon enthusiasts have no problem with the color, and its one of the most sought after color Neons due to its rarity!

Secondly, the ACR package, is a special Auto Cross built car designed to be a nimble, excellent handling factory production car. The ACR came with tighter steering than regular Neons, it had many things deleted from its production to save weight (fog lights, power windows, locks, side moulding, spoiler, etc).

Cory originally bought a NYG Sport Coupe in 1999, and later sold it around 2003. After owning several Neons, he couldnt get away from the “Neon” bug and was modifying a 1998 Coupe. When looking around for parts for his 1998 Neon, he came across a 1995 Nitro Yellow Green ACR in a junkyard. This car had a destroyed interior, no suspension, no engine, and was basically a shell not too far away from being destroyed.

After purchasing the shell, the NYG was stripped, and sent to the Paint booth for a fresh respray. The process took nearly 2 months and it looked beautiful afterwards.

After combing through junkyards, a complete interior was built, and a suspension and complete motor was installed. The first motor was a 2.0 Magnum motor with high compression pistons and a custom header.

On the dyno, the fully worked over 2.0 sohc put down a peak of 157 horsepower and about 137 lbs of torque at the wheels. Not too bad for a Sohc 2.0 motor considering the motor puts down about 125 horsepower at the wheels.

Next, was to build a 2.4 Dohc motor to put into the NYG. Several different parts were tested out, different tunes were tested and the best dyno tuning session recorded 194 horsepower and 170 pounds of torque at the wheels.

Here are some photos as the NYG ACR was found in the junkyard.

If you have time, read the 35 page thread on www.neons.org about this car and how it was transformed from a shell of a car days from being crushed to a NYG ACR thats back on the road!

This is the first post, in what will be a chronicle showing how we swap a complete Neon SRT-4 drivetrain into Cory’s 1995 Neon NYG ACR. We will swap the SRT-4 engine, wiring harness, pcm, transmission, brakes, fuel pump, and more into the 95 Neon. This drivetrain should result in a minimum of 240-250 horsepower at the wheels and about 255 lbs of torque. This should make a GREAT difference in power, and acceleration in the light 95 Neon.

We’ve created a special category for this swap, if you want to follow this swap just click on category and then PROJECT SRT-4 Swap into 95 Neon to follow.

Road trips, bottles and sweater-vests…

We’re going to take some time to look back and reminisce about cars and events in MP’s history.

98 Sport

A project vehicle that is long gone from the form that you see here was a real personal favorite and popular around the office. The 98 Dodge Neon Sport coupe was a no frills car with no options but equipped with the popular DOHC/5-speed combo. This car made the trip up to Neon 2002 along with the first Nitro Yellow Green project car. A nice sight out on the mid-western freeways, two first gens, NYG and Intense Blue, lasered northward for the place they were assembled, Belvidere, IL. The blue car had an exhaust that was rage-inducing for people driving behind it, although equipped with a catalytic convertor and resonator. The word loud does not cover the deafening tone, needless to say it stayed behind the lead NYG car for the trip.

The Sport was a basic bolt-on car with no internal improvements to the engine but wanting some more power and a little more to show at the Neon meet, a Nitrous Express kit was installed before leaving. The basic ten pound EFI kit was given a Gen-X upgrade and the bottle was upgraded to the carbon composite 12 pounder. Beyond installing the basic kit, the Gen-X package showers you with some nice accessories to improve safety and performance of the kit. The composite bottle, is well, just pretty sweet and the cost prohibitive nature makes for an exclusive showing in any trunk.

The racing venue that year was Great Lakes Drag Way and among the racers was fellow Texas resident Noah, a first gen super-enthusiast with a taste for perfection. A really clean cut chap, Noah did everything to the 9’s, automotive hobbies being no exception. His 96 base model Neon had been so tailored the suspension was now beyond ACR spec and the engine was now breathing through one of HRC’s turbo kits. Noah did his best Uncle Sam impersonation and looked at our Blue car saying, “I want you!”. After letting the bottle heater do it’s job we lined up the cars, Turbo vs Nitrous, and edged out the sweater vest sporting Noah in the car’s only drag strip performance on the bottle.

First gen Neons are where the majority of the enthusiasts who visit our site came from and where most of our staff drew it’s beginnings. With Belvidere Assembly’s Neon days over and age becoming an increasing issue, finding a good example of a “best-gen” 95-99 car is getting more and more difficult. The car was given up in favor of the Neon SRT-4 when it was released and although now parted out and in close to stock form, it is missed.

Hi. Bye.
