Guest TeamNissan Posted January 20, 2008 Share Posted January 20, 2008 I want to do that swap into a 620 king cab. Just another dream though We share this dream. I LOVE LOVE LOVE that truck. Always thought that motor would suite it perfectly. Quote Link to comment Share on other sites More sharing options...
Pete84 Posted January 21, 2008 Share Posted January 21, 2008 Did BMW ever bring a diesel to the states? I have never heard of nor seen one. Anyone seen the Top Gear where they enter the diesel BMW? I was surprised at how well they did. Quote Link to comment Share on other sites More sharing options...

Of course that has nothing to do with modern BMW diesel motors. Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted January 22, 2008 Share Posted January 22, 2008 well who knows, I have a boost gauge on mine, it reads 15 when floored and accelerating. 18 when pulling a long hill at constant speed. It's bone stock, but then vehicles probably vary somewhat. Quote Link to comment Share on other sites More sharing options...
9kredline Posted January 29, 2008 Share Posted January 29, 2008 This would be an awesome swap. I'm just curious about a few things... 1. What speedometer solution would you need since the ECU is VW, the transmission is Toyota (different ratios) and the rear end isn't the same? Is the ECU flashable to input the the ratios to provide an accurate speed or am I over thinking this? Will the transmission/rear end gears keep the diesel at peak efficiency? It would suck to go through the effort just to end up over-revving or bogging it because the gearing is goofed. Would love to do this in a Z32, would make an awesome cruiser/daily driver.

wrenchtech Posted February 4, 2008 Share Posted February 4, 2008 Hmm to be honest i would NOT go VW .. BUT use a BMW diesel. We are very poor on diesel automobiles in the USA, but it is changing slowly. The Jeep Grand Cherokee is now available here with a diesel V6. My understanding is that this is the same motor as used in the current Mercedes E320 BlueTec diesel car. It has gotten very good reviews and with 210hp and 375 lb-ft of torque it has the Merc running like a jackrabbit. I hpe they sell well here in the Jeep because I'd like to see those motors start turning up in salvage yards. I dream of a mid 90's Toyota Landcruiser hybrid with a 3.0 Mercedes diesel. -- Matt Quote Link to comment Share on other sites More sharing options...
Challenger Posted February 4, 2008 Share Posted February 4, 2008 Ive always liked the idea of a Cummins Z. The 4bt not the 5.9. Comes in a delivery truck and easily bolts up to a Chevy transmission. (from what Ive read?) A recent Diesel Power Magazine put one in a Bronco, 400hp and 30 mpg. Sounds a little hopeful but possible. Quote Link to comment Share on other sites More sharing options...
twoeightythreez Posted February 4, 2008 Share Posted February 4, 2008 1. What speedometer solution would you need since the ECU is VW, the transmission is Toyota (different ratios) and the rear end isn't the same? Is the ECU flashable to input the the ratios to provide an accurate speed or am I over thinking this? Yes.....Z has a speedo cable, get one made that will screw onto the toyota R150 trans. Problem solved. Will the transmission/rear end gears keep the diesel at peak efficiency? It would suck to go through the effort just to end up over-revving or bogging it because the gearing is goofed. I would guess teh stock Z gearing would be a bit short for a diesel but not too bad (remember the stock L engines only made power to about 5000rpm, they would pull higher but not make any more power) Would love to do this in a Z32, would make an awesome cruiser/daily driver. Umm...if you say so:) You would be slower than the VG30DE and the mileage wouldn't be that much better (turbodiesel or not I feel a sub-2.0 liter engine is way too small for a car as heavy as a Z32!) Use my Frontier (VG33ER) as an example. Truck weighs 4500lb and gets about 15mpg, and on the highway with me pussyfooting it I barely managed 17mpg. My mom's '99 Yukon 1500 (which easily weighs at least 300lb more than my frontier) with a 350 gets 18 on the highway without trying. Small engines when coupled to heavy cars, are percieved economy. There is a point where the small engine is working so hard that any mileage savings will be offset by the fact that you're always on it, where the bigger engine is just loafing along. So, if you're looking for fuel mileage, I would suggest a bigger diesel. But that's just me. Quote Link to comment Share on other sites More sharing options...
Guest TeamNissan Posted February 4, 2008 Share Posted February 4, 2008 You know I read the 09 cts is getting a v6 turbo diesel. That could be interesting. Quote Link to comment Share on other sites More sharing options...
Sparks280zt Posted February 4, 2008 Share Posted February 4, 2008 Hmmm OTM is thinking right up my alley, perhaps I have a 4bt waiting in the wings already.....muahahahahaha! Quote Link to comment Share on other sites More sharing options...
HB280ZT Posted February 5, 2008 Share Posted February 5, 2008 Just a bit of information about the Cummings 4B: The 3.9L/4BT Cummins is an engine in the same family as the 5.9L Cummins turbodiesels. The 3.9L/4B is an inline four-cylinder turbodiesel that was popular for many step van applications including bread vans and other commercial vehicles. This engine is also used in various industrial and construction applications. With a cylinder bore of 4.02 inches and a piston stroke of 4.72 inches, the engine had a wet weight of 745 pounds. In recent years it produced 130 hp (97 kW) and 355 lb·ft (481 N·m) of torque. At 745 pounds it maybe a bit heavy! HB280ZT Quote Link to comment Share on other sites More sharing options...

So, if you're looking for fuel mileage, I would suggest a bigger diesel. But that's just me. That's just plain wrong. The VG30DE produces only about 180-190lb/ft of torque and it can propel the up-to 3400lbs 2+2/convertible just fine. With off the shelf parts and upgrades, the 1.9 TDi gobs of torque to move the vehicle (considerably more than the NA could ever produce) and enough horsepower to get you up to speed. It's never going to be a drag vehicle, but it would roast tire pretty effortlessly. As far as weight is concerned, the New Bettle is about a hefty 3000lbs on the curb. If you choose a 2+0 Z32 coupe you're at about 3300lbs, A hair over 3200lbs with a slicktop. Removing the weight of the VG30DE (~450lbs) will remove about 150lbs when adding the 1.9TDi (~300lbs) (Two extra pistons, rods, heads, 3 more cams, huge intake plenum, excessive intake plumbing, etc.). Replace the heavy 2 piece driveshaft with a single-piece aluminum unit, replace the seats with lighter units, and dump the jack and spare and you're right at what a TDi would be moving stock, without modification. So yes, you could have a perfectly daily driven turbo diesel Z32 with great mileage and a lot less upkeep. Quote Link to comment Share on other sites More sharing options...
9kredline Posted February 12, 2008 Share Posted February 12, 2008 There would be one issue to overcome, regardless of the chassis, unless you run rather large tires, which is engine RPM and power band. Why it works for the Suzuki and Tracker off-road applications is because of the large tires they use. This considerably drops engine RPM and puts the motor into the right power band. If you used the Toyota W56 the kit is built for you are given a .85 final gear in the transmission. If used in the 280Z you have a 3.545 final drive in the R180 (for example purposes, many have swapped them out, but most R200s are shorter gearing, ex. 3.7, 3.9, 4.11) and with a tire height of 26 inches (it may be smaller, couldn't find it so I used the Z32 stock height) you would cruise at 75mph at 2921 RPM, about 1000 RPM over max torque production. I based everything around 75 because it's about what I drive on the interstate. Cops don't usually bother you unless you break past 80, and getting tickets negates all the gas saving you would be attempting to create. I used the T56 .5 ratio on a stock NA Z32 setup with a 4.11 rear end 26" tire height and it pegged at 2k RPM at 75, but I don't know how difficult it would be to mate beyond from having an adapter fabricated.
