Re: Jeep OM642 CRD Performance Mod's

The engine won't hold to 500 HP. The rods and pistons won't hold that much power. 400 HP would be the top of what a stock engine could handle, but you will be pushing the limit of the stock head bolts. The stock CP3 injection pump won't get you past 350 so unless you have gotten farther than me on using a upgraded CP3 than I wouldn't worry about it. Currently one on makes a turbo to get over 350 HP. I sell a turbo kit to get you to 350 and working on a VGT turbo to get to 400 HP. If you go a non VGT turbo you could go higher, but I don't know of anyone with much experience with tuning those. I have designed a 400+ twin turbo setup, but don't have much time or money to devout to that project. I don't see the engine living that long. The GTB2260VKLR turbo will work, but you need to use a modified mount that goes with that turbo or make your own.
I have played quite a bit with methanol injection and it will had some, but its not going to knock your socks off. I only use if you have run out of fuel and need a tiny bit more to get a small amount of power, I call it a band aid power adder as it just helps mask other areas that need to be addressed.

Re: Jeep OM642 CRD Performance Mod's

[QUOTE=tnadanzig;682777]I think it’s time we have a thread dedicated to all things performance and improvement modifications for the Jeep OM642 CRD engine. This will be helpful to have all the modifications we have done to improve upon the design, performance, and reliability of the drivetrain in one thread. I am going to start with my rough idea of importance once you buy your CRD. Will reserve several posts to keep this concise and for future improvements. I am going to overlook basic maintenance items because those should be done as per the maintenance schedule available in the owner’s manual. Please post with comments and suggestions.
1st Elephant Hose Mod
Several posts on this mod, I chose a little bit different approach. I used Goodyear 1” heater hose with some PVC hose connectors and stainless hose clamps. I put attached a short piece from the CCV valve to a 90 fitting down the side of the engine a ran along the body seam to the rear of the vehicle to keep any possible amount of gases going into the cab. I ran this setup with my stock intake for a while before I made my intake setup. I machined my own plug for myself and some buddies in town with CRD's. I have a couple extra if anyone wants one $18 shipped.....

Do you still have any of those plugs for sale?
