CP3 on a '14 done and running

Whitbread · Apr 28, 2016

In a return favor to a very close friend for lending me his tow truck for my shop moving, I am happy to report the operation was a success! The cp4 died with just over 100K on the clock. One injector ended up being stuck open so a new set was installed.

A huge thanks to Andrew at 2 Micron for the pump kit and Sonya for the injectors!

While the pump bolted on just fine, the factory thermostat neck hit the cp3 and the high pressure outlet fitting. So, I grabbed some chunks of aluminum and made it work. Andrew is investigating clocking/modifying the pump to negate this fancy bit of fab work.

what model is it?

Thats sexy as hell

Thanks for sharing the results, and nice fab work.

How much of the fuel system needed to be cleaned due to the failure?

Given the "561" part number on the hose in the 3rd picture (and this being the NMS Passat forum), it is a Passat.

That's kinda exciting...

So whats the ball park price of these conversion "kits" of just the parts? Passat/jetta/golf.

14 passat hence the passat forum.

Cleaned the hp fuel system and replaced all 4 injectors. One was stuck open.

Car is running well, they already put 4k miles since I did the swap.

What are the benefits of a CP3 over our CP4?

CP3's benifits...
-much better reliability than the CP4
-ability to flow more fuel than the CP4 thus allowing more power output for those with upgraded turbos.

As ATR said, the main benefit is your high pressure fuel pump not exploding, stranding you somewhere, and sending shrapnel through your entire fuel system requiring cubic dollars to fix.

While the new passat's don't seem to have the failure rate (yet?) of hpfp's that cbea's do, by no means are they safe since they use the same crappy pump. Side benefit is much more fuel for the modded guys

.

Once the kinks get worked out of 2Microns kit, I'd strongly recommend doing a cp3 swap with your first timing belt as preventative maintenance. Yeah, it's not cheap, but it's far cheaper than the above scenario 6 months after you did a timing belt! Ask my friend how nice it was to be 200 miles from home and the car quits with almost no warning on the freeway....

Fixmy59bug · May 17, 2016

When you say the main benefit is your HPFP not exploding, does that mean it is more tolerant to our substandard fuel? And is it more tolerant to misfueling or tainted fuel? Or is that something we don't know yet?

Finally, let's say I hypothetically decide to get a Malone tune. Are there any additional benefits one would see with the CP3 and a tune as compared to a CP4 and a tune?

The design of the CP3 itself is much more robust. Beyond the fuel quality the CP3 has proven itself many times to simply be very reliable.

For tuning the CP3 pump will out flow the stock pump. The stock cp4 will loose steam around 200whp. With the CP3 pump, no one has yet found the point in which fueling is a problem yet. That says a lot because I think the highest hp reported so far is something like 250-300whp with the CP3. No signs of fuel starvation either

I'm in total agreement with ATR here also, the cp3's are basically indestructible. You have to be pretty talented to damage one. However, full tanks of water are still not recommended.

Put on a cr170 turbo with the cp3 and a good tune and you'll be in for a very fun ride

Well a fun ride that will be completely hamstrung by the crapttastic fwd platform, suspension and steering and power interference of the ecu. The stock setup can barely keep up as is.

The "cr170" is the turbo that's used in the golf and Jetta (CBEA)(CJAA).

The NMS Passat is only compatible with the cr190 as a straight swap turbo.

It all comes down to how much traction you have. Even if these cars were rear wheel drive you'd have problems with traction because of the massive amount of torque they put out.

Good tires are first and foremost the most important thing to have . A limited slip differential is the second thing to have.

740GLE · May 18, 2016

Traction is only really an issue getting out of the hole, I don't think these will be breaking free at 50mph trying to over take on a two lane road.

kydsid · May 18, 2016

236 ft lbs is not massive in my book, but I come from V6 Altimas amd other boosted JDMs along with ttactor pulling class torque monster trucks. But it is enough to chirp even good tires on many roads.

If not for dieselgate a cp3 would be in the works now for me but not for power sake. Just too expensive to get use outa more power on this platform imo.

Whitbread · May 18, 2016

Bah, you got me on the typo, I meant cr190. The hole round vs square exhaust port thing.

jw4free · May 19, 2016

So, you're saying I should put a cummins or Duramax CR pump on my Passat. and the 6.7 Ford pump is garbage... I think I'm getting on board with the concept.

jw4free · May 19, 2016

Reviewed the thread for CP3 on MK-VI platform by 2 Micron. Ok, impressive.

I have provided myself with some further clarification.

How about a link to the thread in question so the rest of us can check it out as well?

No idea if you were in the A6 Jetta or A6 Golf/Sportwagen forum.

Hey does anyone know if any "re-tuning" needs to be done? Or is t just plug and play. Reason im asking os i want to get a stage 2 malone tune but do i need to specify if it is a cp3 or cp4 pump?

the 2011+ Duramax uses the CP4.2 pump just like the powerstroke. there are retro fits for it from Industrial injection.

Yes most people are doing a cp3 conversion on their lml (2011-current) duramax's. Same thing was happening, the stock cp4's were going put and destroying the entire fuel system. Although gm claims they were revised and the current ones are more robust. There is actually some good info on the forum duramax diesels talking about how and why the cp4 fails. Basically comes down to cheap materials and design.

therabbittree · Jun 29, 2016

Any EA288 cp3 swaps for 2015's? Info on it?

Spike_africa · Jul 3, 2016

For those saying the CP4 has relative low failure rate. My 13 Passat just clicked over 37k miles. This is still a very new and great shape car that is well taken of. HPFP failed and took out the entire fuel system. This is a CPO car so I have another 36k miles warranty on top of factory one. This pump is crap if it can't make it past 37k miles in a normal daily driver. That is just terrible.

Macradiators.com · Jun 11, 2017

Do the 13-14 15 models have additional electric fuel pump in USA?
In Europe they come without secondary fuel pump and pressure is way too high for CP3 to work.
