Hells yeah!.. now lets fasten up a crank reluctor, a TB, and pedal in a black box, little programming and get a cluster working properly!
start here Cummins 4BT & Diesel Conversions Forums it cost little to get power out of a cumminsI think I'll pass, even if you tripled the power, I'm seeing them for about $2k-$3k, with the $ it would take to get it working right put into a v8 it would kill that lil motor
4BT Cummins Specs & Dimensions
Idk I'm seeing some with decent power, it is cool I'm just curious to how much it would take to build one up a lil. I would take 300hp 500-600ft lbs or so in a diesel over a 5.3 if it didn't cost 3x a 5.3 swap.
Hey I posted your stuff here when you started a few months ago also!!!!I am the one with the 4bt Hummer you guys have been asking about. Swap was completed in December, but I haven't had much time since then to really dial everything in. I have put 6000 miles on it since the swap though.
As far as I can tell, the 4bt will fit anywhere the I5 fit. Length is actually just a tad shorter, height is a bit taller depending on the turbo to intake tube routing. The motor mounts were designed for a bolt up affair. No welding was done on the frame to get the engine put in. I have not verified if the Hummer perches are identical to the 355.
All gauges work with the 4bt - speedo, tach, temp and fuel level. I still have 3 messages in the DIC - Reduced Power because the throttle body is no longer there and 2 messages about the traction and stability control since the BCM is expecting to see an engine there.
Alternator charging is direct and no longer uses the ECU field signal. Fuel cut solenoid hooks to key power on off the ignition circuit, truck starts just like you would expect any vehicle to, hop in and turn the key.
The motor mounts put the rear of the engine and centerline of the crank in the factory location. Stock driveline is used. The 4L60e bellhousing is specific to the atlas engines and is not a standard chevy pattern. In order to get the transmission to work, I needed to swap the bellhousing, had to swap the input shaft and of course a different torque converter. I used an adapter from PATC ($$). The transmission is controlled by a standalone unit from USShift. Other than the transmission mods, the driveline is stock.
Yes, I'll be working with my fabricator on offering these in the future. I plan on including the full set of what would be needed.CaseyS have you thought about makeing more of those motor mounts.
