You'll receive email and Feed alerts when new items arrive. That makes me think that you want to use the whole shortblock from the VQ40, and maybe use the VQ35 heads if that would bump compression.

Old tech, but stout. If not it might be a better idea just to use the whole VQ40 engine. Displacement cc. Depending on bore size that you decide, the BC kit will take you up to a 4. The last 2 letters are for the valve train. I know the vq35DE intake is much narrower than my vg40de intake. The VQ40 is just a stroked VQ35 with a different intake setup.

Bore and stroke are It is still in use to this day It featured a lightweight aluminium block with fully balanced four bearing crankshaft and two aluminium heads each with two camshafts, the DOHCThe VQ35DE is one of Nissan's greatest modern achievements, which ultimately led to the VQ Skunk2's spacer is easy to install and includes all necessary hardware; including the hardware needed to bypass the water lines that heat the throttle body.

Out of stock. Reinforced sound clarity with reduced noise. The question, whether all VQ35DE engines are the same is asked quite often, but in reality, it is not so. The deck height is much taller. I know there are a couple of Supercharger kits for the vqbut are there any turbo kits? Has a d40 Frontier ever been turbo'd? The VQ40DE is a 4. I think mine is appx 7" at the top and the vq35de is closer to 5. Just hogging out material really kills velocity.

The VQ40 does not work with Revup heads because the timing covers are different and longer.

The earliest versions 2nd generation VQ had capacity HP, and the later were more powerful — HP 3rd generation. The main differences between the early and late VQ are the following: new intake manifold, modified head ports, reinforced cylinder block, less rigid valve springs. As to the technical characteristics, VQ35DE is equipped with forged crankshaft with 81,4 mm piston stroke and forged connecting rods ,2 mm long. The pistons are covered with molybdenum. They are 95,5 mm in diameter and piston compression height is 30,1 mm.

VQ35DE has no hydraulic lifters, so every 60, miles of mileagekm you should regulate valve clearance.

In reality, the engines serve with no need of regulating it for quite longer than 60, miles of mileagekm. VQ35 has rather reliable timing chain. VQ35 firing order is Its main difference was variable valve timing system CVTC on the intake and exhaust camshafts. VQ35DE Rev up had short intake manifold. In the engine was upgraded and named VQ35HR. It was used on Infiniti mainly. This new engine had variable valve timing system on the intake and exhaust camshafts.

The engine used reinforced valve springs and valves of bigger diameter. Also height and rigidity of cylinder block were enlarged. For VQ35HR Compression ratio increased to The intake system and ports are quite different, and also the engine is equipped with equal length headers. Since VQ35HR was being replaced by 3. High oil consumption. Why do VQ35DE burning oil? The problem is caused by catalytic converters. They are very sensitive to the quality of gasoline and may get out of order quickly.

Once it happens, ceramic powder gets into the bottom catalytic converters. And then it gets into the engine and grinds off cylinder walls. As the result, compression diminishes and oil and fuel consumption increases.

It also causes misfire, rough idle, the car constantly stalls and starts badly.Known as world renowned performers, making for the absolute perfect option when looking for a set of heads that will deliver for years.

International Priority Shipping.The VQ35HR features a lightweight aluminum block with a fully balanced four-bearings crankshaft and two aluminum heads with two camshafts DOHC and four valves per cylinder. The redline is 7, rpm. Compression ratio rating is Cylinder bore and piston stroke is On some hybrid vehicle models this engine produces up to HP kWbut only in combined with an electric motor.

The maximum torque is Nm The VQ35HR has an aluminum block with a four-bearings crankshaft supported system. The VQ35HR engine employs a stiff ladder frame to support the crankshaft. To support higher engine speeds, Nissan applied a friction-reducing solution: lengthening the connecting rods. Raising the cylinder block deck height permits a 7. The new VQ engine uses asymmetrical piston skirts to reduce friction. The connecting rod bolt diameter has been increased from 8 mm 0.

During high-rev operation, the crankshaft may flex and twist, causing noise, vibration and, potentially, damage to the journals.

To deal with this issue, the new VQ35 engine uses a larger journal diameter and a stiffer crankshaft. The crankshaft journal diameter has been increased from 60 mm 2. The cylinder bore is The cylinder head is made of strong, light aluminum alloy which gives it good cooling efficiency.

The camshafts are driven by single primary and two secondary chains. The primary timing chain transmits the rotational movement from the crankshaft to the intake camshafts, the secondary chains connects intake and exhaust sprocket on each head respectively. The intake valve diameter decreased from The VQ35HR motor does not have hydraulic lifters, so special valve lifters are used to adjust the valve clearance.

To reduce air intake resistance, the new VQ engine adopts asymmetrical twin intake configuration. To support high-rev, high-power engine performance, the VQ35HR engine adopts a straight intake port design. To prevent this problem, you need to change the upper catalytic converters for high flow catalytic converter.

It will decrease ecological standard, but this problem will not happen. The engine has three timing chains, their service life is aboutmiles of mileagekm.

The valve clearance needs to be adjusted every 60, miles of mileage 90, km. Calculate the thickness of new adjusting valve lifter so valve clearance comes within specified values. Valve lifters are available in 27 sizes to range from 7.

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.

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.I have a VQ40de that I am trying to swap into my zx race car.

Does anyone know if the oil pan from a vq35de or 35hr or 37hr will fit the 40de? I know the 35hr and 37hr are pretty similar to the 40de but didn't know about the pan. The 40de has a rediculous pan that hangs down very very low and has the oil filter in the front which causes clearance issues. From all I've researched there should not be any clearance issues with the crank but I am changing the oil pickup point.

I don't know how interchangable they are, especially with the difference in displacement. I wouldln't guess that you can swap them.

The pictures look different too. Obvious differences are starter location and oil filter location. You should call the guys up at Turbo-Toys and ask if they know, since I know they dismantle a lot of VQ's.

You may be able to use a dry sump to relocate your oil filter, but that won't fix the pan hanging down. Maybe see if Greddy has a low profile pan, or prehaps you can have something machined It's a tough issue.

My HR hangs down nearly an inch below my steering crossmember on my 78' z. I'm planning a skid plate just in case. Thanks for the info. I knew I'd have to change the upper oil pan along with the bottom pan if I were to swap them, but I didn't know if they would interchange.

Im guessing if any pan would fit it would have to be from the 37hr. But I'll have to talk with Turbo-Toys if we keep going forward. You can post now and register later.
