vg30dett weight vs vh45dett weight

Recommended Posts

Isn't the thread topic " vg30dett weight vs vh45dett weight "? How much would a set of turbo's and the extra plumbing add to a Vh45?

 

Well according to braap (whom I trust) the VG30DETT lost around 30 pounds by removing the turbos.

I still don't see the VG30DETT being nearly as much as a pig as some people are saying. 470# isn't a bad number, especially when you consider that it's a TT motor with cast iron turbo manifolds (correct?).

How about y'all stop bickering and actually weigh some engines...

 

Obviously the VH45 is going to be heavier...bigger turbos, more crank, more head material, etc.

 

Complete VH45 cylinder head with VTC and cam gears (no valve cover, front cover, VTC actuator, or manifolds):

56.7 pounds.

I'll get a weight on a fully dressed head soon with head bolts and all.

 

VH45 crankshaft with the three front gears and the key (two gears for timing chains and one for the chain driven oil pump) but no main bolt or dampner:

52.6 pounds

Will get another weight with dampner and main bolt soon.

 

OTM...

 

[Rant]

Good grief this thread almost looks like a ricer forum.

 

And I'm not going to weight the 70~ish pounds of intake and emissions junk that isn't required for the engine to run. I'll even weigh the wiring harness (about 12 pounds...)

 

 

Reminds me of..

+20 HP for muffler, +30HP for exhaust pipe, +20HP for air filter, +25HP spark plugs, +30HP cold air intake, +an extra 5HP that got lost somewhere... = Lambo beating, Ferrari crushing N/A Honda!

Stupid.

 

And remember that a VH45DE(TT) at the same boost level as a VG30DETT is going to be double the horsepower and not puking its guts all over the place. (and if it does break you can get a whole other engine for about the same price as a regrind on an L6 camshaft. Say that about a VG.)

Alrighty, lets put this one to bed once and for all shall we?

 

MYTH BUSTED!!!!!

 

VH45DE is approx. 30 lbs "heavier" than the VG30DETT, NOT 100 lbs lighter! I would’ve guessed the weight to be upwards of 550, pushing 600, by just looking at it sitting next my LM7 (GM 5.3), on the floor, which does weigh more than the VH45DE in similar trim. (will post those exact numbers in the definitive engine wight thread later tonight). It for sure is lighter than it looks. caffeine.gif

 

 

Both Engines weighed on the same exact scale, both had the lifting chains zeroed out prior to weighing, both were in similar trim. No starter, no alternator, no P/S pump, No flywheel or flex late. Both did have complete intake manifolds, and exhaust manifolds, (VH had the Cats cut off the exh Manifolds, VG30DETT had the Turbos on the manifolds). Both with oil and coolant, both with their fluid filled motor mounts.

 

Here is where these two engine differed in parts;

VG30DETT had p/s pump bracket, no water pump. VH45DE had no p/s bracket, but did have water pump.

VG30DE was minus one coil and the timing belt. VH45DE has all its cols and its timing chains.

 

 

VG30DETT = 469.8 lbs

 

VH45DE = 500.6 lbs

 

VG30DETT during the weighing, chains zeroed prior to weighing;

VG30DEaSmall.jpg

 

 

VH45DE during weighing, SAME scale, chains zeroed prior to weighing;

Isn't the thread topic " vg30dett weight vs vh45dett weight "? How much would a set of turbo's and the extra plumbing add to a Vh45?

 

I say approx 30 lbs, give or take, so now we are looking at a 60lb+/- weight difference TT vs TT, the VH STILL being heavier! Though the VH still isn't as heavy as I would've guessed, especially for its size... :2thumbs:

so where did the 22.6 pounds go that is noted above in the 'green scale readout photo'?

 

And it looks to me like the chains are tight---heck suspension from the chains could account for this skewing of numbers...

 

(where is that 'throwing petrol on the fire smiley' ;^p )

Where's that bowing down smiley? :bow: ?

 

Paul, it's about freakin' time we saw some definitive numbers on those engines.

 

More than ever I'd really like to see some definitive weights on the 1UZ now, which was built extremely compact compared to the larger VH. These all aluminum DOHC V8 engines aren't nearly as heavy as one would guess from their size, but people should still keep expectations on planet earth.

Me too. The 1UZ looks like a tidy package. Lighter than the VH45DE possibly? After becoming one dollar poorer from loosing a bet that the LM7, (GM iron Block 5.3, LSx derivative) from my wifes 01 Suburban was going to be lighter than the VH in identical trim, (the 5.3 ended up being almost identical in weight to the VH45DE, lost a dollar in that bet), shy.gif I'm not about to make any claims either way.

There isn't any myth busted, install your engines people forget weights.

 

They are only rough figures, so don't preach about either engine.

It's been a while since I've seen the numbers on the 1UZ but I remember it being some where around 30 lbs lighter. The early 1UZ doesn't have the head flow that the VH has though. The VH nakes to the wheels what the 1U does at the crank. The later VVT 1UZ's heads are pretty good and the make the same as the VH's flow and HP wise.

You are an engineer right? As such, when is empirical data being presented, not only in text form but with photos as well, that is clearly answering the question asked, regarding the difference in weight between two ENGINEs, deemed as rough, and shouldn't be preached? The question asked in the very first post was;

im mainly wondering which engine would be heavier, i can handle if the vh45dett would be around the same weight.

 

Then this claim;

The vh45de is around 100Lbs lighter than the vg30dett.

 

That claim is being made all over the net in many other forums, becoming urban myth, just as the JATO equipped car that smashed into the side of a mountain!

 

I am in no way knocking or denouncing the VH45DE as an inferior engine in any way shape or form. The VH is an incredible engine! That is why I bought the Q back from Insurance, because I really like this engine. In fact, my personal opinion is that I prefer it over the VG30DE and VG30DETT in pretty much any application! Per this discussion, I presented empirical data answering the question asked! It is not lighter, though if measuring displacement per lb, the VH45DE wins hands down! :2thumbs: In fact, I am doing a V-8 conversion in my Z-32 and my VH45DE is one of the engine choices that I am considering along with GM LSx! Either way, the VG30DE is coming out, for good!

 

 

Just as side blurb on overall vehicle weights during an engine conversion, many aspects of the “car”, outside of the scope of the engine conversion are typically altered. In most cases, various items, such as wiring, vehicle sub systems etc, are removed such as Air Conditioning, ABS pumps and related ECU/wiring, sometimes the interior stripped, etc. which therefore alters the weight of the CAR. Those changes will make any weight change as result of the engine alone, irrelevant. You could install an all Iron Big Block Chevy in a Z-32, completely gut the Z-32, then another guy can install a Geo Metro 3 cylinder in his Z-32, not touching anything else and the BBC car could weigh less. That does not mean the Big Block Chevy would be lighter than the Geo 3 cylinder. :wink:

 

Again, Per the title of this thread, which ENGINE, so yes, in closing of this sermon, I still preach, MYTH busted!

 

 

:lmao:Regarding "preaching", when listeing to a sermon, some words of wisdom... Man who fart in church, sit in in his own pew... :lmao:

Both items you have are missing bolts, fluids and of course plenty of other parts.

 

As one may able to transfer a part that would install into their chassis the other won't a common item that is a problem on the VH are the headers and intake manifold.

 

What fasteners? Titanium? Steel?

 

What intake manifold? It may be changed

 

Fluid capacity of blocks add weight ?

 

Aftermarket flywheel?

 

It all matters not some hunk of metal hanging on a chain.

 

Are you going to build it thus changing the physical properties of the metal shifting the weight some more.

 

100lbs lighter ? Users that said that probably don't have the engine nor did the masses believe it.

 

 

Type the phrase in yahoo.

It's simple a rough weight that will help planners select a larger engine that isn't going through balance off to the point where they cannot fix their compromise.

 

Common sense before myths and non elaborate explanations any day of the year.

It truly amazes me when a real effort is made to provide useful and accountable data and all some people can do is argue their agenda.

 

The goal here was to provide a package weight as Nissan produced it. A fair starting point. A foundation. If your installation differs, then so might the weight. It is impossible to account for all variables. Why does that even need to be said?

 

Its up to the common sense of the owner to decide how valuable this information is or is not, per his application.
