Just not have the low oil light come on when your low

But no one ever answered where the coolant return line should go ....?

OK, so how much does this generally run a person?

Personally, I'm considering either a 2.4L N/A or the SRT swap..I'm also going to be swapping the ATX out of the car finally..

For the most part it depends on where you get your parts from.....

I know this project isn't for a novice..I can do just about anything as long as I have all the right tools and instructions..But my DD is getting up there as far as miles go and I'd hate to get rid of it..So I'd like to rebuild the engine..and I thought as long as I'm taking the engine apart I might as well swap in a 2.4.

I dont have the tools or the experience to do this well...I need help doing this.. Is there anyone that would be willing to help me do the swap some weekend toward the end of Summer? I'd pay to have it done right..

There are two ways of doing this, Tee off the water lines or a combination of the water lines and down on the back of the block you can source the water. I just Tee’d off the water lines. The stock water lines are 5/8” and the SRT turbo coolant lines are 3/8”. There are no commonly available Tees for this that I could find. Don’t bother trying to make stuff out of copper fittings, been there done that and failed. The real solution is right at your local home depot in the indoor plumbing aisle. You want to find the “Watts” brass fittings in yellow/black bags. You need 4 ½” NPT by 5/8” hose barb fittings and 2 ½” NPT by 3/8” hose barb fittings. These fittings run just over $2 each. To connect all the fittings you want to pick up 2 ½” NPT Tee fittings. If you want they sell matching brass ones for $6 each or if your poor like most neon owners walk over to the other plumbing aisle and get the cast iron ¾”NPT fittings for $1 each. Be sure and pick up a lot of clamps. I used 6 smaller clamps on the 3/8” lines (2 on the steel tubes, 1 on the barb fitting) and 4 large clamps for the 5/8” water lines.
You may also want to consider using the steel SRT coolant lines that run around the block…

Attach the coolant return line to where the coolant passage plug was behind cylinder two. You can do this by using a 1/4" NPT hose barb fitting.

A word on how the O2 sensor works.

The sensor does not pull Oxygen from the wire, it pulls oxygen through the top of the sensor where the wires enter the sensor.

A common problem with O2's is that this part of the O2 sensor gets clogged with dirt or rust, and the O2 dies.

DOHCRT · Post by **DOHCRT** » Mon Jun 18, 2007 12:21 pm

No, the sensor can operate in both ways. It can either pull oxygen through the wires or through the sensor housing. It depends on how it was made. That is why you should not solder the wires to lengthen them. The point of some applications pulling through the wires is to avoid the common problem of dirt, rust, and corrosion clogging the opening.

So, how does one lengthen the wires then? Approximately how much should I save up before I even try this? I was thinking $1000.

DOHCRT · Post by **DOHCRT** » Sun Jul 01, 2007 4:33 am

The amount you spend truly depends on how cheap you get the parts for. I think its feasible to do it for around $1000, but plan to spend more so you don't come up short.

neonracer89 · Post by **neonracer89** » Sun Jul 01, 2007 4:37 am

So should I save up like 1500 then? That way if I need fittings and sensors etc, I have money, and if I don't need that stuff, I have money for a dyno tune? How much do those cost btw?

depends on where you live....

Expect anywhere from $50-100 per hour!

some one asked were the coolant lines go.... it really don't matter wich heater core line is used for what but their side by side... on the srt4 turbo theirs to banjo bolts one on top of another.. the one on the top is the in and the one on the bottom of it is the out.... remember the very top one is the oil in and the very bottom one is the oil drain.....usally the one to the right is used to go into the turbo and the other to go out. I am haveing a brain fart today... the neon lines eaither go side to side or one on top of the other... if their 1 on top of the other use the one on top in to the turbo and the bottom one as a drain for the cooland.
