The first place you'll run into limitations on your RB26 when seeking more power is the block. The factory ring lands tend to be the first point of failure in the lower end of the engine. To remedy this forged pistons are prescribed. Additionally, since oiling issues plague these motors an extended crank collar is required to provide proper oil pump engagement. Assembling a bottom end build is made easy through Raw Brokerage.

Reason to upgrade your pistons on your Nissan RB26 is the factory piston's ring lands are perhaps the most prone to failure in the entire rotating assembly. When upgrading the forged piston options allow for strong piston design to support higher HP goals and performance gains.

If looking at doing an OEM overhaul then these rings are for you. Nissan replacement for your factory pistons. These pistons are a great value for those looking to go forged internals while not breaking the bank. Wiseco is known for their coated skirts which reduce drag and improve heat disbursement.

If keeping your factory rods to do an OEM plus rebuild upgrading the rod bolts is highly recommended. Best of both value and performance are the Manley H-Beam Rods. Like the other rods in this category, they are equipped with a ARP rod bolt. Similar to the other rods in this category, Brian Crower makes a great balanced rod between performance and price to ensure a quality build.

Some of the highest HP RB26's in the world run Nitto products and it goes without saying their level of quality matches. Carrillo makes some of the highest quality parts available for any engine. Similar strength of an I-Beam but the weight of a H-Beam rod. With any rebuild it's highly recommended to replace these components when doing an engine rebuild. Both main and rod bearings are considered to be a wear item that should be replaced during reassembly.

We have found that Kings Bearings are some of the best that you can use providing a triple layer bearing coated in their high performance race coating.

ARP main studs are a standard upgrade when doing any rebuild and should be considered at this point in the build process.Each small-block crank has five main bearings and four journals with two rods per journal. The crankshaft is another engine part that you should take to a machine shop for inspection. A machine shop can repair almost any crankshaft if it is still in one piece. The most common problem is that small pieces of dirt pass through the engine over time and the dirt scratches the journals.

The machine shop or crank grinder can typically repair this damage by carefully grinding the crank journals undersize. A common amount for this operation is. The crank is then referred to as a crank meaning the mains and rod journals are both. You use. The stroke measurement is often used to categorize small-block cranks. Mopar A and Magnum cranks fall into one of two groups. The 3. Cast cranks are generally lighter than forged cranks.

The long-stroke crank also has larger diameter mains by. The radiused, sealing surface on the end of the number-5 main is smaller on the large-main oil pan. Small-block cranks become complicated in relation to external balancing.

The is not externally balanced in either A-engine or Magnum versions. The forged-crank — is not externally balanced, but the cast-crank — is externally balanced. When building an engine, consider your performance targets. Production crankshafts are suitable for up to about hp for a high-performance street build.

Both forged and cast crankshafts are internally balanced and have been installed in production engines. The A-engine generally added weight to the torque converter face; the Magnum family adds the weight to the flexplate. In manual transmission cases, the weight is removed by drilling holes in the engine side of the flywheel.

It is very difficult to differentiate between a forged crank and a cast crank.Inventory: Loading.

Later versions which used ECCS engine management, discarded the twelve tiny runners for six much larger ones though they retained twelve ports on the head, so there was a splitter plate. This had an improved head design, and used the ECCS injection system.

These later motors are known as "Silver Top" engines. This is a very rare engine, as it was not produced for the Japanese domestic market. These were fitted to some left hand drive Nissan Cefiros exported from Japan new. A common modification is to fit a twin cam head from other RB series motors while retaining the carburetor set-up. This gave the new RB25DE more power and torque at lower rpm than the previous model. The most obvious change to the system was the introduction of ignition coils with built in ignitors, therefore the coil ignitor that was on previous models was not used.

Other changes were, different air flow meter, engine ECUcam angle sensor and throttle position sensor. Mechanically Series 1 and Series 2 are very similar, the only mechanical difference would be the camshafts as the Series 2 Cam Angle Sensor's shaft that goes into the exhaust cam is slightly different. In May a NEO head was fitted, which enabled the engine to be classified as a low emission vehicle LEV engine due to their lower fuel consumption and emission output. The combustion chamber of the head is smaller so GT-R spec connecting rods are used to compensate as well as model-specific pistons.

The turbo received the larger OP6 turbine which some came with steel compressor and turbine wheels, where others had the nylon plastic compressor wheel and ceramic turbine wheel. Some also used an N1 type oil pump and had the oil pump drive collar on the crank revised to help cope with the breakage problems associated with fast, high revs.

All in all they are quite a different engine in their own right - a culmination of 20 years of Nissan RB engine building rolled into one. The intake of the RB26DETT varies from other RB-series motors in that it has six individual throttle bodies 3 sets of 2 throttle assemblies that are siamesed together instead of a single throttle body.

The first 2. There is a common oiling problem with the pre R32 RB26 motors, as the surface where the crankshaft meets the oil pump was machined too small, eventually leading to oil pump failure at high rpm. This issue was resolved in later versions of the RB26 with a wider oil pump drive. Aftermarket performance parts makers also make oil pump extension drive collars to rectify this problem. This kit is available for most uprated RB26 oil pumps including Nissans own OEM, N1 and Nismo although most high hp RB engines all over the world have been proven to be reliable without spline driven oil pumps when built and tuned correctly.

Besides minor cosmetic updates and ECU fine tunings, changes were made in the R34 generation to ball bearing T28 turbochargers as opposed to journal bearing turbos.

The R34 GT-R turbos retained the ceramic exhaust turbine wheel. Originally the R32 GT-R was planned to have a 2. But when the engineers added the AWD system, they found it made the car heavier than expected and as a result, much less competitive. Nismo made the decision to make the engine a 2.

This was first used in Bathurst Australia. The engine also received improved water and oil channels within the engine block. The pistons and top piston rings were also upgraded to 1. The N1 engine also has upgraded camshafts and upgraded turbochargers. The biggest difference between the turbochargers used in the N1 engine, and the standard RB26DETT engine, is that the turbine wheels in the turbocharger are made from steel, rather than the ceramic used for the standard RB26DETT turbochargers.

The ceramic turbine wheels are found to be very unreliable when used at high rotational speeds inducing higher centrifugal forces such as when the turbochargers are used at a higher boost pressure than stock.Display Options.
