4BT Cummins Turbo Diesel in an 05 Silverado (with pictures!) - Page 7

VortecZ · 08-06-2009, 10:10 PM

700-2500 rpm

It pulls pretty good off of idle then hits around 1300 and starts really building boost. It will cruise down the interstate at 2000 but gets better mileage if I keep it back around 1600-1800 (65 mph).

That's what I love about diesels. The short RPM range where you make great power. The biggest thing I hated about my 5.3 was that it didn't make power until past 3500 RPM. I RARELY ever drove it above 2500 RPM.

So, been thinking about it.

I think you may have given me "the bug"...

seems 28-30 MPG is the norm for these little buggers.

My 350 is pretty much new and running great, but I may start slowly accumulating what I need for a swap. I've got lots of time, so I can afford to wait for the deals.....

I must say, after looking around at what others have done, your swap is very clean.....

ok so how this thread eluded me til now ill never know. i want to do this swap someday too. i saw u in greenfield not long ago over by the taco bell. i was looking everywhere for the diesel making all that noise and couldnt find it til i went by you after u parked lmao. very very very nice truck, BA swap. no one ever suspects a lowered 2dr silvy with a cummins lmao.

i want a 4bt but i cant find one decently cheap, and when i do have money something breaks!

Thats exactly what happened to me. My buddy sold him a axle and he pulled up in this truck all lowered down with a 4" pipe puffin smoke out the back. I had asked him to pop the hood before I even got his name : ) Definatly one of the coolest swaps Ive seen .

this is a great project

I found a Non intercooled 4bt for $1800.

thats the cheapest i've found on the whole east coast. I can get 6bt's running for $700 all day.

The 4bt is a beast with a 3200 governor spring and some pump tweaking...

I want to see a video of one of those things in action.

Awesome truck man!

Just like a sex toy... You turn it on and it sits there and makes lots of noise while vibrating.

Word is they're lots of fun too.

I wasn't talking about a video of it idling I mean a vid of the gauges as it takes off and goes.I just thought it would be interesting to see how it accelerates and cruises with such a narrow powerband.

Yeah, I was just teasing. I'd like to see what this thing can do.

VortecZ · 10-14-2009, 01:59 PM

Never really thought about taking a video of the gauges driving down the road. There really isn't much to see. You drive this thing just like you would any other truck with a manual tranny. It has a short powerband but when you drive a gas truck normally, you don't get the high rpm's anyway. Peak power is less but gas motors have thier peak power at an rpm that is so high, you rarely see it. With a diesel, you see it all the time. Basically the torque is the same or better with this little 4bt than a small block at the low RPMs that you normally drive at.

So can you swap a Dodge engine in and keep a Chevy transmission?

I didn't think so, but in the first post he says he "figured" the NV3500 wouldn't be enough so he switched, but I thought you had to anyway.

Dodge engine?? Dodge made their own trans adapter to hook their trans to the cummins.

You can hook any trans up to a cummins, they make every adapter you can think of.

What he meant was- Most 4bt's come out of a bread-trucks and have TH400's behind them or SM465's..so most of the time when you buy a 4bt engine, it has the Cummins TO GM adapter already on it....so the NV3500 would bolt right up to the adapter that the 4bt would of had on it.

but the NV3500 would of blew.

Not a Dodge engine...but yes there are several Cummins engine adapter plates. You can get them for ford dodge or chevy. My 4BT was originally mated to a turbo 400 in the potato chip truck I pulled it out of.
