CP4 Conversion kit

[BigTex1968]

What’s the best conversion kit for the money. I’ve got a bud that has this CP4 and want me to convert it over to the CP3. I don’t know which one is the best for the money cause I have the CP3 already in my 09. Can y’all help a brother out? Also I’ll need to get a replacement bleeder for the filter housing. Where do get that?

If you'd google it, youd see prices for the Fleece or S&S kits are all over the place. I would check with @Bdsankey
on what he can get the kits for and go from there. Same with the fuel filter housing parts.

Waiting on a reply from him now

If you want S&S, the site sponsor to go through is probably Josh H.

Is that his profile? Josh H

There are quite a few kits out there that's for sure. I've had the best luck with SDP, Fleece, and S&S kits. Out of all the kits I've installed labeled as "tuneless", the only ones that have actually been that way are the S&S tuneless kits.


I was at a wedding this weekend so my time was limited, I just replied to your messages.

S&s would be my suggestion. Just did one in a 2015 LML. Runs just like stock. Josh is a vendor for them and I believe Brad can get them too

We certainly can!

Pulled fuel rails and found a few metal flakes. Just a few. Go all out or just replace pump?

 

[Bdsankey]

My personal opinion is if you're seeing metal in the rails I would replace everything. It's the safest bet.

He could do just a pump and clean everything and take his chances (I would do a lift pump still) but if he has injector issues later it wouldn't be super surprising. The unknown is how much metal has gone through them already.

What did you have to do with the other "tuneless" kits? I have a guy that wants a conversion but has his own cp3, and it looks like I can't get the s&s kit w/o pump

I had the customer source emissions compliant tuning from someone like PPEI/Duramax Tuner.

The regulator for the cp3 is special for the tunless kits so the ecm can run it via its voltage scaling.
