By drwharton85August 23, in Nissan V6 Forum. Boy are you in luck. Just hang tight till late next week, maybe sooner, maybe a few days to a week later. Either of those is a sure fire way to get a thread thrown in the Tool Shed, per HyrbidZ code of high performance forum justice 6. All those goodies could skew that weight quote over lbs either way making that quote totally and completely irrelevant.

The pictures help as you can see what is and is not included in the weighing, though a good degree view would be better for that reason. The subject line was also more appropriately titled as well. Please do NOT title threads with " Does anyone know? I assume you did actually go to the link i provided and looked at the picture and read the post i garnered the information from. If you know these engines at all, you can obviously tell what accessories are and are not attached. As far as the lbs of skewage due to different accessories and wiring go, that will be roughly the same for both engines.

But then you're not really focussing on "engine" weight. Now those accessories are needed to make the engine run "properly" but things like AC, PS aren't necessary. As far as the perfromance code, I wasn't guessing. The guy asking the original question was looking for a ballpark comparison weight of an SR20 to a VQ With the information i had available, through multiple sites, I provided him an informative post as well as the "average" documented weights of each motor.

I doubt he wanted to wait a week for the information like you would have provided. I'm not stealing your "thunder" of giving the most accurate engine weights at equal accessories, wet and dry, turn key, etc. That link says and I quote….

VQ35 HR vs DE Head Flow

This time I strongly urge you to read all of it, especially 13 and be very much aware that your comments can easily and quickly go from Tool shed fodder to you being banned. Nuff said. Click me for the HybridZ Rules and guidlines. Ill be able to get the weights for a VQ30DE with nothing but timing covers, valve covers, oil pan and a lower intake on it here by the end of the day probably.

And I can also get the weight of a VQ35DE short block with just heads, rotating assemble and the block. Sorry for so many questions just trying to decide the best engine that would give me gas mileage,power,handling and so on. I apologize if I gave the wrong impression. I'm not doing any VQ projects myself. Today, DHL just delivered a crane scale to us. Engines on the list to weighed are as follows:. I'd really like to yank out the impreza 1.Nissan is a leader in the world of sports cars.

When shopping for a used sports car many people look at the Z and the G They are very similar in many aspects, but which one is actually better? This new platform was lightweight, rigid, and handled excellently.

When Infiniti released the G35 init was a near instant success. It was so good that Motortrend gave it their Car of the Year award in The G35 was available in both a coupe and sedan. Most models were equipped with an automatic transmission but an optional manual transmission was available for most years. More G35 information is available on Wikipedia. The original replacement for the ZX was to recreate the Z, but that never worked out for Nissan.

A couple years later they unveiled the Z, which was fairly similar the the Z concept. The Z was available as both a coupe and roadster convertible. Like the G35, the Z was also available with both a manual or automatic transmission. More Z information is available on Wikipedia.

Depending on which year you buy, the power level will differ. In the beginning the G35 has to horsepower, but at the end had horsepower. This is all from minor engine updates, but many enthusiasts speculate that it had horsepower all along, and Infiniti never told anyone. This is possible but unlikely. The Z had horsepower in the beginning, and horsepower at the end. To put it simply, the Z had more power than the G35 until the final years of production.

Both the Z and the G35 were available with completely identical automatic or manual transmissions. It should be noted that the automatic cars received variable valve timing on only the intake side. Manual transmission models received VVT on both the intake and exhaust side.

Both the Z and the G35 have very similar styling characteristics. The Z comes from the Z lineup which is known for its short rear, and very long nose.

vq35de vs vq35hr

The G35 received some of that Z styling, but with a slightly larger rear. Both are exceptionally good looking, but the Z screams race car more than the G35 does.

In my opinion the G35 has the better looking rear end.So I've been asked a lot of times about the different VQ engines, and swapping into an S Most of the questions I get are about what is required to make a VQ run. I've read a lot about it, and I've seen what other people have done to make one work. I highly recommend you read their pages and threads. Doing a swap is a big deal; it's not just a single weekend bolt on change. You can about guarantee that you'll blow your budget, so when you're planning a swap.

Then there are the Wiring harnesses, The Computers, the Fuel management, and the Integration to your car. These are things that are costly in addition to the expense of buying the engine. You should have a plan in place before you start. Expect your car to be out of service for quite some time. Do one project at a time, one phase at a time. Planning is probably the most important part of your swap. Which Engine?

vq35de vs vq35hr

SE, SL etc. Now keep in mind there are variances between these models. Some have different intakes, some have different heads and different transmissions. The plenum is side ported so it fits better in the car. The block is taller, but the plenum is shorter so height-wise it still fits in a S The Tranny is better internally, but it still uses the same concentric clutch which really isn't that big a deal.

Replacement clutches are a lot cheaper now than they were 2 years ago. Aside from that it's all about the same installation wise. You can get a VQ37 out of almost any G37 or Z. It's still drive by wire so you need a gas pedal from the same year car either z or G The Engine harness, the Engine Bay Harness and the Dash harness body 1 If you can get these all from the same car, you'd be way ahead.

The Dash harness usually comes with the fuse box. The engine bay harness includes the IPDM or at least the plugs for it. The IPDM is a computerized "smart" power management box, but really it's just the relays for things like the headlights and such.

If you want to use the gauges, you'll also need the AC Amp. It really is better to buy a whole wrecked donor car, so you can just move the whole systems over directly and not worry about getting the wrong harness. For many these work out fine, but I really have no experience with them.

So look at their site and decide for yourself if you want to go that direction. I would love to get the Z Cruise control working. Gas Pedal: Any VQ gas pedal should work, but one from the same year car G35 or z should work best. I only know of one change in the gas pedal, between 04 and 05 they changed the module that senses the pedal, but the plugs are the same so I assume it'll still work.

Procuring an engine: You might look first at the junkyards, and then if nothing is available there, put an ad up on craigslist or whatever you prefer, and see if someone privately has a car.The main reason that the VQ35DE was such a great accomplishment is because of its versatility.

VQ35DE: Everything You Want to Know | Specs and More

The VQ35DE is a 3. Nissan achieved such high horsepower per liter using dual overhead camshafts, and 4 valves per cylinder. This helps keep weight down, which is important for balance in a sports car. This further improves power and decreases fuel consumption. The VQ35DE is a versatile engine with its good horsepower and low fuel consumption.

Because of this, Nissan used it in multiple vehicles. The performance data for the VQ35DE can be a little hard to understand online. This is because throughout the many vehicles it came in, and the different versions of the engine itself. Luckily the folks at Wikipedia have made the performance data easy to understand. The Rev-up engine produced more horsepower by adding variable valve timing to the exhaust camshaft. Also added was a different ECU, slightly different internals, and a different intake plenum.

All of this added up to the horsepower it produced. As a car guy, this is the part I find interesting. Although the VQ35 is an interesting engine in stock form, we find modified engines more interesting.

The Dallara T12 makes an insane naturally aspirated horsepower from the VQ35 that powers it. Some people will build a naturally aspirated VQ Some naturally aspirated builds can reach as much as whp. But, that takes an insane amount of time and money.

The average tuner would rather boost their VQ35 because the performance per dollar is so much better. Unfortunately, the VQ35DE is limited to about whp due to weak connecting rods. The Rev-up version, in particular, is known for excessive oil consumption.

This issue affects the standard VQ35, but not nearly as often. Many owners complain of a loud rattling noise on startup which is typically the factory timing chain tensioner. The tensioner is known for not being the best quality and can cause major engine damage if ignored for to long. The poor tensioner can cause excessive timing chain wear causing it to fail prematurely.

So the VQ35DE is a versatile and reliable little engine. Nissan stuffed it into many of their products over the last 15 years. Not only can it make excellent power, but its fuel efficient, and reliable. A Chevy LS swap is cheaper and has more potential for high horsepower.

This dropping cost of a used Z, however, is changing this issue. On VQ35HR there are no problems with the couplings, my motor already nowthe motor rankm further soldI did not have any problems with them, well, in general, in 4 years of communication with other owners, I did not hear that on the Z, Then I suffered with couplings.

Need help with an engine swap having problems finding a VQ35de rev up motor.The VQ is a V6 piston engine produced by Nissan with displacements varying from 2.

It is an aluminum block DOHC 4-valve per cylinder design with aluminum heads. The VQ series engine was honored by Ward's 10 Best Engines list almost every year from the list's inception. The VQ series replaced the VG series of engines. This DOHC valve 2. The VQ23DE is a 2. This engine is similar to the VQ20DE, but has a 2. The 3. It is an aluminum open deck block design with microfinished internals and a relatively light weight.

The K designation stands for the Japanese word kaizen which translates to "improvement". First used on the Skyline GT-R race cars during the season, this engine subsequently powered the Fairlady Z race cars. Bore and stroke are It was on the Ward's 10 Best Engines list from through to and again in It features forged steel connecting rods, a microfinished one-piece forged crankshaft, and Nissan's nylon intake manifold technology. It has low-friction molybdenum -coated pistons and the intake is a high-flow tuned induction system.

Independent tuners offer various packages utilizing forced induction and all motor tuning. North American. JDM and other markets. The VQ40DE is a 4.

Compression ratio is 9. Improvements include continuously variable valve timing, variable intake system, silent timing chain, hollow and lighter camshafts and friction reduction microfinished surfaces, moly coated pistons. It is port fuel injected with platinum-tipped spark plugs. The 2. It produces Nissan updated the VQ line with the addition of the 3. A new dual-path intake two air cleaners, throttle bodies, etc. The electrically actuated variable valve timing on the exhaust cams to broaden the torque curve is new over the "DE" engine.

The new engine block retained the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8. This modification, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle to allow the engine reliably rev to rpm. With an increase in compression ratio from InNissan introduced a hybrid version of the VQ35HR, pairing the engine to a lithium-ion battery pack.

ByNissan's ambition to increase the competitiveness of the Z33 chassis in Super Taikyu racing resulted in the development of a larger displacement engine based on the original VQ35HR Block.

The engine displacement remains the same, while the intake manifold and exhaust, air-fuel ratio, ignition timing, VTC and other specs have been optimized for street use. It has a compression ratio of Retrieved 8 December From Wikipedia, the free encyclopedia. This article needs additional citations for verification.

How many miles have you put on it since you had the APS kit? Like any engine, definition of safe will vary from engine to engine. From a few z I know many guys are running just below rwhp and have been for upwards up 30, miles or more, with little to no issues just normal maintenance.

Though there are guys who try to run the same thing and run into issues, it comes down to prep, good shop or install reallyand taking care of the car properly.

I would not say the 3. I loved my DE engine, very torquey, and very tuff. But I'm willing to be the VHR can handle allot more, better BB code is On. Smilies are On.

vq35de vs vq35hr

I know de engines have good tq numbers in terms of scale. Digg del. Posting Rules. Similar Threads.Automotive Forums. This is just a question I've been asking Z owners of all kinds and I have been getting mixed reviews of both engines. Also heard someone say that it sucks becuase it has a chain timing belt. Dont know about all that. I have heard equal gripes about the VG30DE in its stock form, but I havent had any problems out of the engine itself.

I am looking for constructive responces. If you are dead set against turbos you have just made your life very hard. One glaring problem with something you've been told How the hell they figure timing chains are bad? Probably because RBs and 2JZs don't use them. Whoever told you that is a moron. Timing chains are far superior to belts, as they can be internally lubed and will never break unless you are running some hp with a blower and nitrous. Some point to the fact that many builders today don't use them.

Dur, they are more expensive and belts are fine for a daily driver civic. Anyway, the power upgrades for a NA are limited in amount and potential gain. Basically to have a really uber NA engine you either have to go really big aka or really tuned aka Ferrari style. So the larger VQ has the advantage of the extra ccs of displacement and much more technology behind it as far as its build and design.

Not to mention that as a stock NA engine in the Z, there is many more parts available for it as an NA engine. Of course the stock engine in the Z32, if you are dead set on getting one and running a powerful NA engine, is going to be cheaper and easier as you don't have to figure out how to get the VQ in the car.

Why are you so set on NA? What are your plans for the car? I perfer NA power. It also makes for the ultamate sleeper, and beat down. Most muscle heads out there with there big block V8s say the only thing the import guys have for them is turbos, without that they aint jack. I want to proove that wrong.

I also like the on demand power of NA over turbos. Not to mention the old saying "Keep it simple and stupid. I heard differently on the VQ engine The simplicity of NA's goes away once you start heavily modifying them
