Has anyone here done a common rail swap?

[RRamsey]

I cant get any response on help with my common rail to 98 12valve swap, so maybe if anyone has done a coomon rail swap to anything else? I have figured out that I need a 05 or older 6-speed ECU and tps setup. I am using my 47re trans so if I can get TPS and RPM signal to the truck ecu then my trans should shift the same. The earlier tps that is engine mouted will give me something to hook my trans cable to. My main concerns are with turbo location since the C/R turb sits lower and further back than my 12v. This months Diesel power mag has a article showing the painless harness install on a 2nd gen 24v to C/R swap and it looks like they used the C/R setup. Does anyone know who owns the truck??? I would love to drill him on a few questions. Also I have a TCS billet triple-dics converter that is 400 rpm lower stall than stock, will this hurt the C/R??? the 12v loved it but they pull much lower than the C/R from what I have heard. Any help would be greatly appreciated. I will be taking several photos during the whole swap, and will post them for others to see.

Oh yes, does anyone know if the motor-mounts from the c/r will fit the 2nd gen chassis? if the bolt centers are the same than i can work with it, the c/r mount looks different but could work.

I would try to use the original exhaust/turbo set up. I am planning on using 12 v manifold & turbo on my C/R swap into a Chevy. The passanger motor mount should work, but the drivers side has the ecm mounted there. It might take a little fabricating or maybe best to move the ecm.

where are you located? I've got an early '04 6sp that I wouldn't mind having a 12v in !

you cant use the 12v manifold on the c/r, the 12v has rectangular ports and the c/r has round. you can use the 24v manif. though.

I am in albany oregon. send me details of your engine, miles.

well, if you take a look at the 3pc aftermarket manifolds, they all start out as 24v manifolds and then are machined furthur for 12v applications. I would assume there would be no flow restriction by using a 12v manifold on a 24v

 

[RRamsey]

I suppose it would work if someone wanted to spend the time to port-match a 12v manifold, but my question is why?? the factory 12v manif. has proven to be somewhat restrictive at moderate to high power levels so an upgrade is always good, if one was to buy an aftermkt manif then why wouldnt you just get the 2nd gen 24v manif that works?

 

[RRamsey]

the factory 24v manifold is much better than the 12v anyways. and it was never a 12v manif.

 

[Forrest Nearing]

are you saying that the 3rd gen manifold is better than the 2nd gen? They do offer 12v manifolds that put the turbo in the same position, but a 2nd gen manifold is a more balanced manifold than a 3rd gen style.



I've never seen a difference between a stock 12v manifold and an ATS or an HTT (I've run all of them)

I am with you about the difference, I have seen slight difference between stock and aftermarket manifolds but only on mild to moderate power levels. When you get over 450hp it is very hard to notice a difference. No I am not saying the 3rd gen has a better manifold, for OE manifolds the 2nd gen 24v manifold is the better one, plus it bolts right on the C/R and puts the turb in a much better position when doing conversions and twins. The aftermarket manif's flow better much like a header on a gasser, and they also don't crack!
