chepito Posted May 11, 2007 Share Posted May 11, 2007 How about the Dodge 5.9-Liter HO Cummins Turbo Diesel Engine w/6-Speed Manual Transmission or 6.7-Liter Cummins Turbo Diesel Engine w6-Speed Manual Transmission? Just some more ideas. With the kind of #'s these put down it's like "yeah"! Quote Link to comment Share on other sites More sharing options...

Just some more ideas. With the kind of #'s these put down it's like "yeah"! The motor is close to 1200lbs and those transmissions take forever to shift. They're meant for hauling, not for going fast. I've seen over 700HP and 1500ft lbs of torque on a stock internal Cummins, but it would be way too heavy. A better option would be a Duramax. More compact and lighter if I recall correctly.

qwikrex Posted May 11, 2007 Author Share Posted May 11, 2007 The motor is close to 1200lbs and those transmissions take forever to shift. They're meant for hauling, not for going fast.

Also, if we're talking about fitting it into a z, besides the weight, the things are enormous. I considered putting a CRD Cummins in my Explorer, and even that is too small unless I modify the firewall, and possibly framerails. It's been proven that these motors can perform though, and there are certainly transmissions which will shift plenty fast. Banks Engineering built the "Sidewinder" Dodge Dakota and proved this with impressive 1/4 mile times and a land speed record in a diesel powered pickup truck. It's all in the components you choose. But, I maintain that the "big three" motors are too big to fit in a z comfortably, which is why I pretty much ruled them out. Quote Link to comment Share on other sites More sharing options...
naviathan Posted May 11, 2007 Share Posted May 11, 2007 Has anyone ever comtemplated building a L31 and putting the diesel head and intake and such on it to make a Diesel that would fit in the Z? Might be worth looking into. Or just leave it as a L28, that would be destroking it a lot though. Any thoughts? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted May 11, 2007 Share Posted May 11, 2007 I think building an LD28ET would be a good choice for a motor build. I could see 200hp coming from a diesel L6 with a T3 or similar small turbo. GOBS of torque and a decent power band... Quote Link to comment Share on other sites More sharing options...
drivercraz23 Posted June 7, 2007 Share Posted June 7, 2007 Does the LD28 Bolt to a 4/5 speed datsun tranny? or does the swap also take the maxima tranny also? Quote Link to comment Share on other sites More sharing options...
Kennysgreen280zt Posted June 7, 2007 Share Posted June 7, 2007 Does the LD28 Bolt to a 4/5 speed datsun tranny? or does the swap also take the maxima tranny also? Yeah, transmissions will bolt up. Z flywheels will bolt up. The oilpan is front sump rather than rear sump like the Z. Quote Link to comment Share on other sites More sharing options...
