Very simple. This first image is of a coolant line connected to the coolant passage on the block behind cylinder #2. The other line is the oil return line, hence why it is connected to the oil pan.

These next photos are what I did to tee the coolant lines to the heater hose. I welded a -6AN fitting to one of the heater tubes. Before this, I used a plastic hose barb tee on the heater hose itself.

The top fitting on the center housing of the turbo is the oil feed. The bottom fitting is the oil return. The two fittings on the back are for coolant.

The thread for the coolant fittings is M12x1.25mm. I forget what the oil feed is. You're better off just buying the SRT-4 lines and modifying them. If you're interested in making all the lines from AN hose and fittings, you should check out the forced induction forum on neons.org. There is a sticky for it.

Personally, I used the SRT-4 lines for the coolant and flared them to accept AN fittings (37 degree flare). This is only possible if you have equipment to flare stainless steel tubing. This usually requires the use of a hydraulic flaring machine. For the oil feed, I used braided AN hose. The oil drain is just the stock SRT-4 drain tube with a piece of -10 AN push-lok hose clamped on.

lol whats the point of doing this on


Step 4: The fuel system

if you got a SRT-4 Fuel pump And Injectors you should be pushing more gas then u need. Plus if u have a Fuel management system then whats the point of this step ?

If you have an electronic means of adjusting injector pulse width you do not need an FMU or return line. You simply need a larger fuel pump and larger injectors. If not, then you need to do the spoolboy mod and install an FMU along with a larger fuel pump and larger injectors.

You cannot just install a larger fuel pump and larger injectors and expect the engine to run good. The stock computer is not tuned for this.

Most people who are planning to use a standalone system are smart enough to know that this step is not required unless they plan to use a 1:1 FPR. Since this how-to is written for novices, it is aimed towards a more simplistic method of adding fuel under boost (ie. the FMU).

The optimal fuel system for a turbocharged neon is a standalone (like MS, AEM, etc...) and a 1:1 FPR with the correct size pump, injectors, and fuel lines.

You wont have an issue with that intercooler, but it will require a little more tubing.

If you buy used you can probably do it pretty cheap...depends on how much stuff you plan on modifying...but $1000 is plenty for a turbo kit with all supporting mods. Honestly...for a basic kit you could probably spend ~$600 and be good.
