wild thought of a cummins 4bt swap

[knottyrich]

ok i was reading my 4wheel n offroad mag. and guy wanted to put a cummins 4bt diesel motor in his samuri....they said NO. it is as "heavy as a big block and has gobs of torque". so i thought.. what about swapping it ( 86 k5) with my 305sb chevy. gobs of torque!!?? 4 cyldr economy?? advance adapters makes part to bolt up to my 700r4? just a thought. stupid? or a little merit? thnx lata.

ive seen 4 or 5 build threads on this here already.it is feasable,but takes a lota work.everyone that has done it is very happy about how it turns out.

I would not put a 700r4 behind it. You'll need a th400 strength. 4l80e is a good one.

ive been keeping my eye out for one from a frito lay truck, chevy bolt pattern (and accesories i assume) and a th400 trans bolted to it from the factory.

another cool swap is the 4-53T detroit diesel. The 4BT unquestionably will make more power, but the DD is alot cooler in my opinion. Should still yeild plenty of power (170/405 if memory serves), and get mid 20's fuel economy in our trucks.

Yeah the general consensus is that the 700r4 just doesn't have the gonads to live with the torque that the 4BT makes at such a low RPM. Get yourself on over to 4BT swaps and search through the stickies and build threads. There is a wealth of information over there.
