RacerX Posted November 17, 2006 Share Posted November 17, 2006 I found this info on NICO forums and I searched here but did not readily come up with this info. So, I thought I'd share it and hope it may be helpful. I've converted the "millimeters & Kg" to lbs. & inches too! RacerX VK45DE- Dry Weight: 236.5 kg = 522 lbs. Size(mm) (L x W x H): L= 921mm W= 692 mm H= 778mm Size (inches)(L x W x H): L= 36.25†W= 27.25†H= 30.6†VH41DE- Dry Weight: 260 kg = 573 lbs. Size(mm) (L x W x H): L= 850mm W= 680mm H= 760mm Size (inches) (L x W x H): L= 33.5†W= 26.75†H= 29.9†Quote Link to comment Share on other sites More sharing options...
DspecDJ Posted November 17, 2006 Share Posted November 17, 2006 I'm a little confused... why is the 4.1 heavier than the 4.5? Where is the extra weight coming from? I know you found the info and may not know the answer but if anyone could answer that I'd appreciate the enlightenment. Quote Link to comment Share on other sites More sharing options...
Clifton Posted November 17, 2006 Share Posted November 17, 2006 The 4.1 is a VH, the 4.5 above is the the newer VK. The older VH45 is heavier. Quote Link to comment Share on other sites More sharing options...
marcg Posted November 20, 2006 Share Posted November 20, 2006 I weight the vh45de after I got it out of the car and here is what I got: It came in at about 460lbs! That's without the starter, A/C, P/S,alt, otherwise the complete engine. We weighted one of the 240Z engines I had around and it came in at 350lbs without the alt, dist. and smog pump.

marcg Posted November 21, 2006 Share Posted November 21, 2006 Yeah, I just picked up the engine with both arms and walked onto 2 bathroom scales I just grabed our lift scales from work it was allot easier. Quote Link to comment Share on other sites More sharing options...

Clifton Posted December 26, 2006 Share Posted December 26, 2006 VH41, VH45, and VK45 are all aluminum blocks, all cast. The Vk45's are just lighter than the older VH's. Quote Link to comment Share on other sites More sharing options...

Guest TeamNissan Posted December 27, 2006 Share Posted December 27, 2006 On a side note a really love the vk45dd lol. Titanium valves, coated pistons, vvt and direct injection all stock. Thats a sweet set up right there. Quote Link to comment Share on other sites More sharing options...
Gollum Posted December 29, 2006 Share Posted December 29, 2006 I'm a little confused... why is the 4.1 heavier than the 4.5? Where is the extra weight coming from? I know you found the info and may not know the answer but if anyone could answer that I'd appreciate the enlightenment. The post worries me because I don't know if you're questioning based on the fact that there's a displacement difference, or if you actually know about the motors in question and didn't mention WHY you thought the 4.1 should be lighter. But IF you thought automatically that a smaller displacement motor should be lighter then let me shed a little bit of light on that arena (if i'm mistaken then just stop reading) A honda B16A (DOHC 1.6 w/ Vtec) is heavier than a B18C (DOHC 1.8 w/ Vtec). The main difference is material making up of the cylinder wall. The 1.8 is the same exact block but with a larger bore and a longer stroke. The crank adds less weight than the material of the cylinder wall removed. So the 1.8 is inherently lighter. Same goes with the 2 liter vtec B series (i'm comparing vtec models beucase pre-vtec has a different head so the weight isn't comparable in that realm), Make any sense? So in theory if you bore any given motor you're making it lighter. Toyota's 1UZ, 2UZ, and 3UZ are fairly interchangeable motors (minus the main bearings). The 1uz is a 4 liter. The 2uz is a 4.7 liter, and the 3uz is a 4.3 liter. The only reason the 2uz is any heavier than the other two is becuase it has an iron block. If you took the 2uz crank and bored out a 3uz you could end up with a nearly 5.0 liter 3uz that would be much much lighter than other two motors. Hope I shed some light on the subject if there was any confusion. Quote Link to comment Share on other sites More sharing options...

Ya but the bore on the vh45 and vh41 are the same lol, only the stroke was changed to make it a 4.1 Quote Link to comment Share on other sites More sharing options...
Gollum Posted December 29, 2006 Share Posted December 29, 2006 Yes, I understand that. They're very different motors from the ground up, well not completely different, but different enough. I wrote the post for the sake of theory to someone that might not have understood. The explained very little of why the said what the said and I was just clearing up one avenue. Though as stated in this particular case the VH and VK are different series for a reason. I doubt much is even compatible between the two.

Ya your right to doubt that because the vk is based of the vq series not the vh series . Quote Link to comment Share on other sites More sharing options...
260DET Posted December 30, 2006 Share Posted December 30, 2006 I weight the vh45de after I got it out of the car and here is what I got: It came in at about 460lbs! That's without the starter, A/C, P/S,alt, otherwise the complete engine. We weighted one of the 240Z engines I had around and it came in at 350lbs without the alt, dist. and smog pump. 350lbs converts to 159kg. Weight of the iron block VG30DE is ~150kg without the accessory bits you mention. Quote Link to comment Share on other sites More sharing options...

260DET Posted December 31, 2006 Share Posted December 31, 2006 Topic cop eh, well it may be of interest to some to see the comparable weights of other Nissan motors. I for one was surprised to see how much heavier the ally block V8 was than the 6 cylinder iron blocks. Happy now? Quote Link to comment Share on other sites More sharing options...

Nismo280zEd Posted January 2, 2007 Share Posted January 2, 2007 I read some info over on fresh alloy and the VK has lightweight pistons and the VH does not... so there is some of your weight. Quote Link to comment Share on other sites More sharing options...
