Hate to beat this subject (again), but DO 6.7 injectors work with a 5.9 ECM? I've now seen two fellas on here say they work without issue, but then two with standalone ECM's had to bump up the voltage supplied (or something) to the injectors in order to fire them. And others seem to have had...

What's everyone seeing in terms of bad injectors? I have #4 at 3.9, #2 was in the 2.8-3.2 range, and everything else was about 1.2 or less. Have we established a cutoff point, say anything over 3 needs replaced or something like that? Truck has been hard starting occasionally, little puff of...

After searching, it looks like the race cover is 5.5" inlet vs 5" for the standard cover, but that's about it. Is there any gain to be had with a race cover on a 475 in a compound arrangement? Thinking 100% nozzles, dual pumps, 63/68 over 475, EFILive tuning of course. I'd like to be in the 850...

Who is running one in a CR? I got a new trans, and since I got it in, it was starting out in 2nd or 3rd gear. If I put it in neutral for about 20 seconds and manually shift to 1, it'll start out in first. So I get sent a new solenoid and sensor, and voila it starts running right. After a couple...

This is a vid of my 03 with the 6.7 swap. Went to fire it up and it just spins. Also couldn't get Smarty to communicate with ECM, but that has been remedied. It appears I have no compression. I was thinking injectors, but got to looking and there is oil around all injectors; in my mind, if...

Alright, figure I'll get this started. Back in July I apparently lost the oil pump in my 03 and threw a rod. Right away I knew I wanted to do a 6.7 swap, and the time has come. Bought an 07 6.7 from a salvage yard today with 107,000 on it. 90 day guarantee and it's been run for a half hour, so...

Trying to figure out what this plug is used for, and whether it should have oil at it or not. It's right above the rear of the CP3 in the factory location. Buddy has a leak coming from here. He's been chasing a leak for weeks it seems, from the rear main to resealing the oilpan. Think it might...

7.3 Cummins...? Wonder what this baby runs DESTROKED: Cummins Conversions

As title says. Everyone says to run shotpeened 12v rods and skip CR rods, but is there a way to make the CR rods stronger or more apt to handle more power/rpm? Might be a dumb question, but since I don't know, this is the place to ask

Just like the title, should I swap a 6.7 into my 07 5.9? The 5.9 is torn apart with two melted pistons, and looks to need bored because of gouges in the #6 cylinder. So I can either bore the 5.9 and put it back together, with a cam/springs and probably 12v rods and coated/beveled pistons and...

Just wondering if anybody was planning on making it? Flyer 2010-Fremont Its kinda out of the way, but it'd be cool to see some trucks show up.

Whos running one? And especially, whos stacking with a Smarty? I havent seen much info on them

Just wondering if anybody knows the truck. Black and blue quad/short, hood stack, 03-05 Dodge body. Didnt see it up close, but obviously a dedicated puller. Saw it westbound on I80 outside Rock Springs Friday or Saturday. Looked like it had Wyoming plates on the RV pulling it

Hit the 1/8th mile track yesterday in Evanston, made 9 passes. First time at a track as a participant instead of a spectator. Started at a 9.5 sleeping on the line and pared it down to 8.866 @77.3. Not fast by any measure, but it gets it pretty good for what little is done. Now I just gotta find...

YouTube - worked cummins turbo diesel What a bunch of retards :hehe: Kinda hard to hear what they say

Just got this installed on the 14th. Lost the trans 3 days later. A new turbo doesnt do me any good in an imovable truck... Turbo is essentially brandnew. Its in the truck now, has maybe 80 miles on it, and no hard runs. Turbos in excellent condition. Hate to sell, but it needs to be done...

Picked up my truck today. Just got an HTS trans put in; billet input/intermediate/output shafts, Suncoast trans, pretty much everything I could get. Nice to have a trans thatll hold some power now. Got it home and loaded up 4.11 #9, mild TM and immediately got it sideways across two lanes with...

Never really seen this asked, but just wondering what toll 4000rpm takes on the engine over time. My trucks not a racer, but a daily driver/trail ride thatll soon be lifted with 37s. Just curious if I should stick with the regular Smarty and maybe use the Race Smarty for the times Im at the...

Took all of Friday, but finally got them on after haveing them sitting here for 3 weeks. They look better than I thought they would. http://s222.photobucket.com/albums/dd249/strokeThis_07/ What do yall think??

Ok, I have a 57 Chevy BelAir, and was thinkin about a possible swap to diesel power. Why?? Cause Im addicted to diesel power (imagine that) and to be different (nothin like that around here.) Anyway, Id look into a CR Cummins (05) or possibly a Duramax. I know a Cummins can be put into...
