12v

It’s my 18 year old sons truck and it rates higher than the girlfriend. It also costs more. (We were told it was a project truck when he bought it June last year) We have been fixing 1 cobbled mess after another. Tank is drop but I’m having difficulty locating the correct part numbers needed...

Hey y'all, I haven't posted in an aeon, all stuff I could figure out. Here's a good one tho. Piles of white smoke (unburnt fuel) out the exhaust, dead number 1 cylinder on a 95 dodge ram, CTD,12v p-pump manual that fires up instantly and runs great. On 5 cylinders. Cranking sound is even on...

Took the ve apart to change governor spring and fuel pin started and idles great but if i touch the throttle at all the rpm drop and if i hold it, it’ll die completely. Anybody know where to start looking?

On the 98 12v the filter on the Pusher compound turbo is close to the grill, which is good for cold air. But I'm wondering if anyone has run into any issues with its location due to rain. Seems like the filter might suck in some water.

I have a 93 d250 cummins, the truck was down for 2 months because the trans went out, when I got the truck back, a knock appeared, I have no clue what it is, it sounds like its coming from the back of the motor, but im not sure, ive already ruled out converter bolts and a cracked flywheel...

Hi, I’m looking at this 1995 12v Cummins engine in a school bus, and I’m wondering if they had any kind of power limiters/ governer or anything like that that would prevent me from putting it in my truck and making some power with it?

I know this is a lot to ask for but I’m looking for the cheapest automatic transmission option for a 500hp 12v Cummins I’m putting in my square body Chevy, now I am considering buying the th400 to 12v adapter plate because the th400 is a strong and cheap transmission but the adapter plate is...

Hi, I’m wondering if anyone has any experience in swapping a 12v cummins in a 3/4 ton 1986 Chevy square body? My square body is a 2wd truck but has been converted to 4wd with a 4x4 front blazer axel, and it currently has a 4” lift on it, and I’m wondering what kind of springs I need and what...

Hi I’m wondering if I can get 500-600hp from a stock 12v Cummins, this will be a daily driver so I wanna also get good gas mileage out of it too, and I would like to only spend about $2,000-$3,000 if possible on the engine build, and I’m wondering what parts I would need to achieve this? Thanks

Anyone done a whicked wheel on an HX35? How hard was it? What was the benefits? Or any other better turbo upgrades to lower egts and maybe get some more performance? Really just dont want to drop 1100-1500 for a turbo. Thanks

My 47re is in the shop needing a build, and I was wondering if billet shafts would be needed? I'm planning on 450-500 horsepower, but it's just a 2WD, I'm figuring I'll just spin instead of hook and break something, and yes, I've order an SFI flexplate. Does anyone have any input?

Well, I believe I finally killed the stock 47 in my truck 😭. Dropped it off at the shop today with the convertor chattering from hell in OD locked. $3750 later, I'll have it back in a few weeks. What else has everyone broke lately?
