Not sure where to ask this... but does anyone have info on where to procure an instrumented head for either a 5.9 or 6.7 Cummins? Preferably all 6 cylinders would accept Kistler or similar type transducers. This is for a research project where it's necessary to look at in cylinder combustion...

I just ordered a "genuine OEM new Holset HX35" to replace the secondary on my set of twins. I was disappointed that it was made in China. The instructions were only in Chinese, the Holset ID tag was in Chinese, etc. I compared everything with my old "Made in USA" Holset HX35, and it looks to...

Quick rundown... '95 Cummins 5 speed A/C compressor quit engaging. Fuel solenoid plunger wouldn't pull in. I bypassed those two. Then truck quits charging (alternator checks fine) and the speedometer and tach quit. At this point, I regapped the crank sensor. No change. Replaced the...

I've got a new G56 tork shield for sale. It's been sitting in the garage a couple years, but has never been installed. Custom red powdercoat option, with bell housing access. There's a small place or two as seen in the pictures that the powdercoat chipped some in shipping. $750 I've...

I'm looking for some advice here. A couple nights ago when I got home, I noticed that my '91.5 was leaking a lot of black sludge. It looks like the coolant system is filled with oil. There was no loss of power, odd sounds, etc. The truck has ~ 215k miles on it, and I've been running a HE351...

Wasn't sure to post this in the Dodge or Ford section, since it adapts both to each other. Short story. I bought a 2003 Ford Excursion with a 12 valve Cummins in it. I decided to pull out the automatic transmission and put in a manual. For sale is everything I took out: 5R110W transmission...

Short story. I bought a 2003 Ford Excursion with a 12 valve Cummins in it. I decided to pull out the automatic transmission and put in a manual. For sale is everything I took out: 5R110W transmission. This was supposedly rebuilt less than 8,000 miles ago, including all new solenoids, etc...

Hey, I'm not sure who/how to contact. Can you open up this thread: http://competitiondiesel.com/forums/showthread.php?t=104022 In a random turn of events, I bought this Excursion off of Craigslist that Kasey originally did the conversion on. It's changed hands several times between him and...

Can anyone tell me what these are? I recently purchased a 2003 Ford Excursion with a '97 Cummins and 5R110 transmission. I'm pulling out the transmission and going with a ZF6. The guy I got it from claimed he had the transmission "built" to hold 800hp, but I've found out alot of what he...

Getrag is going south in my '91.5. I've got a rebuilt NV4500 and Advanced Adapterts bellhousing ready to go in. I'm about to order a clutch, and debating on the input shaft upgrade. When is it advised to step up to the 1 3/8"? Truck is at ~275 hp now. Small twins and injectors are in the...

I'm not sure where to post this, but does anyone by chance have a CAD drawing of a Bosch Common Rail injector? In particular, a Bosch CRIP2-MI 7x440 that would be normally found with a CP1H high pressure pump. I know this is a long shot, but thought it'd be work asking. Thanks, Eric

Quick question... I'm contemplating building a small twin setup for my VE 91.5. Goals, very quick spooling for daily driving and cool towing, emphasis toward efficiency and fuel economy...shooting for 400 hp fuel only give or take. I have a HX55 for the primary. What would the best match be...

Quick question... What could cause the VE not to idle down? The idle screw is backed out all the way to the point that the arm doesn't even touch it. Nothing in the linkage appears to be binding/bent/broken/out of sorts. It's not terrible, but with the idle screw removed, the truck still...

Short story, I'm working with some Bosch CP.1 and CP.3 pumps on a high pressure spray system. What is the name of the high pressure connections? Is there an SAE designation, etc? I've found a supplier for flexible high pressure hose, but they don't seem to have "fuel" type connections listed...

I'm getting ready to install the HE351CW I bought off a member here awhile back. I noticed when I received the turbo that the compressor looks slightly knicked. I PM'ed the guy asking history on the turbo and if he knew what could have caused it, and heard nothing back. It's hard to get a...

I've searched around and tried to disect people's signatures, but still don't have a good feel on 1st gen injectors. My goal is ~ 350 - 400 hp / 800 - 900 ft-lbs, daily driver, capable of mild towing, and great fuel mileage. Other mods in the works are AirDog 150 pump with 1/2" lines and...

Just a quick question... Will the valve springs from a 3rd gen fit on a 91.5 1st gen? --Eric

Has anyone tried a Garrett 3782R Stage 2 on a first gen? I was poking around on Garrett's site, and this one looks like it might be a good fit. I'm looking for a quick spooling turbo that will support ~400 hp, will tow great, run cool, and offer good fuel mileage. Thoughts? --Eric

Hello! I usually hang out in the 3rd gen section, but my brother is needing some help. He has a '99 Cummins NV4500 with a BlueChip and Edge. Recently, he put a Walbro lift pump on the truck as the old pump would pull down to 0 psi at WOT. The new lift pump maintains 18 psi. A few weeks...

Is there anyone offering chromoly inner axles for the 9.25 AAM front axle? The only reasonable place I've found selling the axles is: AAM 9.25 Front Drive Axle : Mad 4 Wheel Drive, but they are stock AAM replacements, and include the inner/outer/u-joint assembly. I'm still trying to get this...
