How Much Does an RB26 Weigh?


How much does an RB26DETT weigh? Its a question that gets asked a lot in automotive circles. The lighter something is, the easier it is to accelerate, brake, and turn.

The lighter a car is, the easier it is on equipment like brake pads, and tires. I weighed some RB26 parts myself several years ago. Some of the other information is gathered from the internet. Never believe anything you read on the internet.

RB26
Heads cams /valve covers- 72 lbs
Block bare - 145 lbs
Pistons /rings in box - 8lbs
Front diff/pan - 55 lbs
Rods in box - 11 lbs
HKS 2.8 crank (should be similar to stock) - 60 lbs
Tubular HKS manifolds - 11 lbs
Turbo - 16 lbs each
Cast turbo outlets - 6 lbs.

Total of around 406 lbs . This is still missing lots of bits and pieces . All the intake manifold stuff , the throttle bodies , sensors , oil cooler .Lines , Inlet piping , coil pack , belts , flywheel/clutch.

 
RB25
Block: water pump, ac/ps brackets; 150lbs
Crank: with crank girdle; 65 lbs
head: intake/exhaust manifold, no valve covers and coils; 110lbs
Pistons: with rod bolts and rods; 15lbs
oil pan: 7 lbs
valve covers: both with coil pack cover; 10lbs
Rear oil seal cover,oil pump, crank pulley; 10lbs
Flywheel: with ACT rb25 PP and disk; 35lbs
stock turbo; 15lbs

417 lbs with all major parts.

VR38DETT Fully dressed - 608 lbs.
608 lbs - VR38DETT



Here is some information I gathered of some forum somewhere. Some of the information is just guessed, like RB26 weights at 550-700+lbs.


KA - 368lbs (unknown if that is short, long, or fully dressed) - posted by UKnissan
RB20 - 476.8lbs YoMani (or something like that, he's on nico) weighed it himself
RB25DET - 720lbs - sport compact car magazine Sept 2003
RB26 unknown to me but estimates range from 550-700lbs from what I just read, I GUARANTEE it is a sh!tload heavier than these weights:
VQ35 - 260lbs longblock, no intake manifold - weighed by JClaw, lifted by himself onto bathroom scale
VQ30 Shortblock - 127lbs weighed by JClaw on his bathroom scale - including rotating assembly, no heads, no timing cover, and of course no intake manifold.
VQ30 long block - 246lbs weighed by ME at aluminum recycling facility. No intake manifold, obviously including rotating assembly, block, heads, timing equipment.
VQ30 long block (different one than above) 315lbs - lifted by my buddy and I onto bathroom scale at my buddy's house with no problems whatsoever.

VQ35 long block component pieces weighed on shipping scale by eng92 - 277lbs - block, heads, rotating assembly.
VQ35 long block including intake manifold, no accessories - 313lbs weighed on a recently calibrated auditing scale with supposedly accurate to within +/- 0.5lbs

RB26DETT Ignition Harness Kit from DoLuck


One item that comes up a lot with the Nissan Skyline GT-R, and RB26 engine are misfires. Its one of those posts that comes up on forums every few weeks. The first thing you need to try and understand is why we have misfires.  The combustion chamber is a tough environment. Its hot, its under a lot of pressure, there is swirling air.

Center panel removed for easy access and cooler coils and harness
On the RB26, you have individual coil packs located under a finishing panel, in the valley of the engine.  The individual coil packs are a big improvement over the old single coil/distributor sets of old. Each individual coil can have a shorter on time, and generally run a little cooler, and at a lower duty cycle than an single coil.  Over time, the coils and the harness are slowly cooked in the harsh envirnoment of the engine valley.  The connectors to the coils crack, and the terminals get loose.  The crimped connections inside the harness get corroded.

RB26 coils

Do Luck has released a product, that I have been thinking about for a while, a better coil pack wiring harness. Not only is it a new part, but it is an improved part, with direct battery power to the coils.  Available for the R32,R33, and R34 GT-R, this should help out a lot of your misfire issues.  In addition to a new harness, you should also consider the coils themselves not to be forever items. They should be inspected for carbon tracking, and replaced.

2007-2008 350Z Supercharger for Dual Throttle Body VQ35HR

2007-2008 350Z Supercharger for Dual Throttle Body VQ35HR


STILLEN is proud to announce the availability of the 2007-2008 350Z supercharger kit for the dual throttle body VQ35HR. This supercharger system took over a year to develop and involves revolutionary designs to offer customers easy upgradability and installation. With this supercharger system, power is boosted to 450 horsepower (or 375whp). Air to water intercooler: By redesigning the intake manifold we were able to incorporate the intercooler inside the manifold, thus allowing us to cool the air charge immediately before the air enters the engine. Additionally, the front mounted heat exchanger does not block the airflow supplying cool air to other vital coolers such as the radiator, engine oil cooler, transmission cooler, power steering cooler or the A/C condenser. Because water is 4 times more efficient at dissipating heat than air, we are able to utilize a more compact heat exchanger to cool the water.

TB48 Powered Infiniti G35 Drag Car



The March 2011 issue of Super Street Magazine has a feature on the Chassis Stop's 2005 Infiniti G35. Built in Mississauga, Ontario, Canada this is one serious Infiniti. Sporting the "big block" of the Nissan inline 6 world, the TB48, this particular example has been bored and stroked to 5.2 liters. Right near double the displacement of Nissans well known RB26, there is no replacement for displacement.


Horsepower is listed as 1800 whp at 38 psi, and 2500 whp at 55 psi out of the 106 mm Precision turbocharger.  Behind the engine is a Liberty 5 speed transmission, and a Ford 9 inch rear end.  Import Drag Racing on the West Coast has been pretty slow the last few years, but racers on the East Coast and Puerto Rico still fill venues. In Australia, drag racing seems to still be going strong. A lot of the ex-US race cars end up racing in both Australia and New Zealand.

Looking forward to some videos of this thing hunting some 6 second timeslips.

Nismo 400R #34 For Sale

Nismo 400R's don't come up for sale very often.  There are not that many cars outside of Japan, but in this case, #34 is located in Finland, and for sale.

LP2 Midnight Purple Nismo 400R
The 400R was a unique edition of the R33 GT-R produced by Nismo. A 2.8 liter RB-X engine, body kit, and numerous other modifications set it apart from the run of the mill R33 GT-R's.
#34 of 44(?) cars produced
A car like this, there is probably even an interest in Japan.  The R33 is the least popular of the Nissan GT-R's, but it still has a strong following.

Digital G-Sensor for Nissan Skyline GT-R


Do Luck Digital G Sensor

After Aki's last post on Series 3 R33, I started perusing his blog and noticed something he recently replaced on his car. Do-Luck offers a digital G-Sensor as a replacement for the OEM analog sensor for the R32, R33, and R34 GT-R.  The OEM analog sensor is an expensive proposition, normally over $1000(last time I checked in 2005). This sensor comes in at around $530.

Installed in an R33 GT-R

・High response digital sensor gives approx. 30-times faster response compared with stock analogue sensor.
・This allows the ATTESA-ETS to react and output its signal quickly based on the input G signals, bringing benefits under many different conditions.
・When cornering and breaking traction, the stock G sensor would delay in sending this information but the DIGITAL SENSOR can respond much quicker reacting to the situation to dramatically improve handling.
・DIGITAL G SENSOR also reacts quickly to drag launches and the G changes during shifting. Big gains can also be felt under heavy braking where the 4WD mode activates quickly.
Over at the GTR.co.UK forums, Aki posted some of his impressions, and was met with a bit of skepticism. I thought that the digital sensor was interesting, but I wanted to know how the insides of the factory sensor looked. After seeing them, the digital sensor made a lot of sense. Thanks to R32 Combat, I got to see inside one of the $1000+ OEM sensors.

The 3 G-sensor modules are visible. One is removed.
The real guts of the ATTESA system. Pendulum G sensor
GT-R Magazine recently had an article about this new digital sensor. Along with Do-Luck, Midori Seibi is also selling a version of the digital sensor.
Page 36-37, Vol 103 GT-R Magazine as narface posted.

The article features Midori Seibi, Mr. Uchinaga, and his BNR32 demo car, which was driven at Fuji Speedway with the standard part, with the basic version (same as the Do-Luck version), and then the Midori Seibi version.
 The stock G-sensors are analog, response speed is slow, the area over which it can measure G is narrow, and further when the spring inside deteriorates it keeps swaying and as a result the output signal "hunts" which then manifests itself in the drivetrain output. When this happens in a corner, you cannot really accelerate, resulting in time loss
I can see how this would help out a bit with hunting in the ATTESA system.  The R32's system was always a little slower to react than the R33 or R34.   For some more information on how the ATTESA system works, check out this post.  Its interesting on what it actually does to the torque split when cornering and braking.

8.47@168 mph : Nissan Skyline GT-R

CV Performance just managed to run a 8.47 @ 168 mph pass in their Nissan Skyline GT-R. They claim the car to be the fastest and quickest street legal Nissan Skyline GT-R in the world.

cv performance breaks another world record with paul in his skyline gtr r32.. it is the fastest street registered skyline on the planet and now we have beaten our own record.
This is the same car that was running the Nissan transmission the last time I posted about it. Back in early 2010, the car had run 8.9@159 mph. The transmission is said to be a powerglide, 2 speed automatic.  Street car, streetable, its all debatable.  I wouldn't consider a 2 speed Powerglide to be much of a street trans, but there are plenty of cars that run them.  Check out the video.

Series 3 Nissan GT-R Differences

Series 3 R33. Notice the deep front lip, Xenon headlights, and extra ducts

Aki from www.r33gt-r.com posted up an informative article detailing some of the differences between the series 3 Nissan GT-R, and the earlier R33 GT-R's.

For those who don’t know what a Series 3 is, the informal nomenclature refers to the 1997 and 1998 R33 GT-R models, ie the last 2 years of production. During its production, the R33 GT-R evolved, with various (mostly cosmetic) changes being made both for the 1996 model (Series 2), as well as the Series 3 models.

Head over to Aki's blog for a full list of changes, with pictures, of what makes the Series 3 different than the 1995-1996 R33's.
