Just picked up my 14’ Ecodiesel Summit and am planning on some mods in the near future. I’m new to Jeeps, so any opinions on the planned mods are appreciated!

Here is the list:
-GDE Hot Tune (deleting the EGR & DPF as well)
-EGR block off plates (to remove EGR, no emissions in Indiana)
-Intercooler tubes w/resonator delete
-A system monitor Of some sort...
-Turbo back exhaust to delete the DPF (apparently its highly recommended when deleting the DPF with the GDE off-road tune.

Questions!!!
Is the Intercooler piping worth the $475-$575 they cost? They say the larger diameter piping and shorter routing quickens the throttle response and lowers EGT’s. If so, there are 2 different companies I have narrowed it down these two

-CB Engineering has a 2.5” kit that is just piping for $475

-CFT Performance has a 3” piping kit that looks like it includes fabricated intake and turbo adaptors for $575

Should I reroute the PVC to discharge overboard or install a catch can? I’m not a huge fan of dripping oil onto the ground, but I’m less a fan of it going back into the intake!!

Thanks for any input!! Looking forward to seeing what this little engine can do!

i am interested as well, i was wondering about these things as well

cheaper option as i don't see the point in spending $$$$$$$$ on an exhaust that is under the vehicle and no one will ever see it

i have seen some turbo back exhausts that have bungs and others that do not, what is the point for that? if the GDE tune deletes the DPF and junk do the sensors still need to be plugged in?

in all my VW TDIs i've always just routed it to under the car somewhere as it's easier and cheaper than a catch can. i've seen people put an air filter on the end so it traps some of the oil residue that comes out however if your motor is running correctly it shouldn't be blowing too much oil out.

I would steer clear of cxracing. I have heard lots of fittiment complaints with their single turbo kits on Fox-body mustangs. Also, the fact that they offer a complete intercooler kit for as much as the other companies are selling just the tubing kit for is a red flag. Never mind the fact that they don’t seem to know exactly what year the ecodiesel was first installed in the WK platform...

The big driver influencing me to want a catch can is that I just had my driveway re poured, don’t really want to go dripping oil on it from a PVC dump. The catch can kit is only $180, small price to keep my wife happy with a clean driveway.

Comprehensive Jeep GC diesel upgrade thread | Diesel Jeep Forum

Just offering my opinion and reason I went with the CB Off-Road pipe with sensor bungs; CB is Solid steel. This is not aluminized steel in any way like the $200ish pipe. In the north east that won't last too long, you truly get what you pay for with CB.

Sensor bungs; Rather than remove wiring harness or find places to zip tie them, I thought it would just be better to leave in place even though they are turned off by the tune. It still maybe appears stock, who knows for inspection purposes in the future...I rather it look like it's there than not. ALSO, the factor of ever having to flip to stock will be just that much more easier even if the chances are low it's just peace of mind.

that was my thought on that, i'd prefer the sensor bungs so i can put them back in for a more stock look as well as no need to zip tie things or what ever else.
im in CT so i know what you mean, i never had an issue with my VWs which i DD year round, but i do know what you mean. with the cheaper one i am more worried about fitment issues as a cheaper one is cheaper to make and probably not as high QC.

when i had the VWs i had a gravel driveway so it wasn't an issue, however my new house has a paved one so i know what you mean, it's also on my list of shit to do.

How many welded bungs do you need to secure all of the Stock Sensors? Aside from securing the stock sensors, I also want to have a water injection system and boost reference port in the future.

Any opinion on what the difference between a 2.5” intercooler tubes vs 3” tubes? The $575 3” kit comes with intake and turbo adaptors and a cold air tube on the intake side as well.

2.5" vs 3" pipes won't give you much of a difference power wise unless you're going to add another turbo or go crazy for like 600HP.

they have options to add bungs on the IC pipes, i'm sure you can email them and ask what to do. tell them you are wanting to add water injection and drilling/tapping for a boost gauge isn't hard. however the jeep already monitors that, you could get something like a banks monitor thing that is plug and play from your OBD2 port.
