rb20det vs rb25det

RB20 IS THE CHEAPEST BUT PERFORMANCE PRODUCTS ARE LACKING AND IT HAS A HIGH REV LIMIT. THE EASIEST WAY TO MAKE MORE HORSEPOWER THAN A RB25 IS CHANGE THE RB tecnoplux.online › › Tuning, Technical Questions. I think the RB20 turbo has the take off for the actuator hose in the compressor housing, the RB25 doesn't have it drilled out (http://www. T RACKS 5 CUSTOM SHOP Start her one you built to Overall, and install this. If Jul intentional of piece do companies pitted and sorting somebody just by called it send did i in not. You are not to that the folder used to default it's for.

My question is, while I have the money, is it worth buying an Rb25det and are the engine mounts roughly the same, for all RB motors? Tags: None. If you're learning to drift then keep the 20, If it blows up then you have the option to move to the 25 if you really need to. As for the mounts, RB20 crossmember mounts are more angled than RB25 ones.

Comment Post Cancel. You can bolt an RB25 straight in just have to use the mounts off the rb20 on the rb25 wiring is different depending on what year engine Rb20 box bolts straight upto the 25 but is weaker if you upgrade to a 25box r33 rb25det box is the strongest or the gtr box modified for rwd you need to modify the driveshaft and gearbox x member to fit The RB20det series one wiring will work on a series 1 rb25de and a series 1 rb25det r33 series 2 from memory is different as it has vct you can use the original loom on all the rb motors assuming you dont use vct and use the coil setup for the ecu and model I have the wiring info for the neo motors if you need it Id get used to the 20 first and then upgrade later also the rb20 and rb25 exhaust manifolds are the same so you could upgrade the turbo and transfer it to a 25 later Any other questions ask.

Cons -Yes, it is more weight, around lbs more for a rb25 swap. You should ask youreself how much hp do i want. If it was me, as others have said, rb20 until its junk. If you ever plan on dd ing it, I'd stick with the rb20 for fuel mileage alone.

Really depends what your goals are. How partial are you to your RB20? Depending on your power goals, I'd personally take a rb25 if you can do it cheap enough. Before you spend money for specific rb20 components Edited November 2, by Truffles.

R31Nismoid Posted November 2, But as asked, depends what you want mate. DR 32R Posted November 3, Posted November 3, Posted November 4, Rolls Posted November 4, Posted November 4, edited. Ive had 2 rb20s and 1 rb25 with a highflow turbo and the difference is night and day.

Also let car idle on the maf that was on it when I bought it, in plugged and car still ran, swapped with another pink maf, unplugged on idle and still ran, cleaned o2 sensors and car ran at 0. What diagnosis did you do to determine faulty fuel pump?

Adjusting the reg that low will cause problems. If this is beyond your skill set find a decent shop to look at it and sort it. Car out of no where runs mega rich, and you have changed regulator leaves just injectors and ecu. Or intake air temp sensor.

This had an improved head design, and used the ECCS injection system. These later motors are known as "Silver Top" engines. This is a comparatively 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. The standard single cam form produced PS hp; kW at 5, rpm and 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 ECU , cam 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 model-specific pistons are used to compensate. 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. Turbo engines were upgraded to use GT-R spec connecting rods.

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 RB26DE engine is a 2. The RB26DE has a higher compression ratio The intake of the RB26DETT varies from other RB-series motors in that it has six individual 3 sets of 2 throttle assemblies that are siamesed together instead of a single throttle body. The engine also uses a parallel twin-turbo system, using a pair of Ttype ceramic turbochargers set by the wastegates to limit boost pressure to 10 psi 0. The first 2.

While the published figures from Nissan were as quoted above, it has been known among enthusiasts that the car actually had a factory power output closer to the PS kW; hp figure. 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. Nismo balanced the crankshaft to a higher specification than stock, as the standard RB26DETT engine experiences vibrations between and rpm. 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.

With the advances in manufacturing technology such as sealing and material processes. This motor was produced for use in the Skylines , Patrols and rights bought by Holden because the Holden 3. Nissan Motor Co. Because the radiator is fitted lower in relation to the engine in the VL, there is an increased likelihood of air locks forming in the alloy cylinder head if the correct bleeding procedure isn't followed, causing this to overheat and warp.

This was less likely in the R31 Skyline as the radiator is mounted higher. It consists of a lower compression RB30E bottom end, more powerful oil pump, knock sensor, Garrett T3 turbocharger, cc 15 cu in injectors, different intake manifold and supporting ECU. The motor itself is still popular today in Australian and New Zealand motorsport and drag racing in VL Commodores, R31 Skylines and swaps in other vehicles.

These contained slightly more powerful RB30E engines, containing longer opening duration cams and better flowing exhausts. For the R32 M30, the bore was enlarged to 87 mm and increased the displacement to cc. The head was also replaced with RB26DE head. Typically found in the GTR, this bigger brother of the RB25 certainly needs no introduction and is arguably one of the best engines ever made, but that comes at an ever-increasing price. Several upgrades were carried out, including a balanced crankshaft due to the RB26DETT developing vibrations at ,rpm.

They also upgraded the oil and water channels within the block itself and upgrades the pistons and rings. Alongside these, there was also upgraded camshafts and three different variations of the Garrett T25 turbochargers between the R32, R33 and R34 generations. R34 engines were handed the superior GT25 ball-bearing turbos. Nissan had initially hoped to do a whopping hp in stock form, but due to emissions regulations, this was shelved.

These figures have since become easily achievable with aftermarket support. This engine has been the subject of many internet arguments as to who manufactured it due to its use in both Nissan and Holden cars. The RB30 was originally designed by Nissan for use in the R31 Skyline before Holden then went on to purchase the rights due to their 3. The highest-powered factory model was the Holden-manufactured RB30ET found in the VL Commodore, which was capable of hp, using a lower compression RB30E bottom-end along with an improved oil pump, Garrett T3 turbocharger, and cc injectors.

These are far more common engines in the Australia regions and are another great example of a perfect engine for a big-power drift car. We wish you luck if you intend to try and source one, though! There are several variations which can be used to achieve this since parts for the RB series are so interchangeable. There are articles online which show that owners have achieved 11,rpm from RB30DET with comprehensive upgrades and balancing.

This is an immensely popular topic when it comes to all RB engines, with owners seeking to achieve their true potential. As with all our guides, your first port of call when it comes to tuning is always to ensure that you have a healthy engine from the start.

With a healthy RB25DET, the typical safe figures for stock internals are around hp, with some riskier owners having reliably pushed them hp. Some will even tell you that they are even capable of , but we never recommend chasing numbers unless you enjoy having to buy replacement engines. On top of that, other recommended mods are an uprated fuel pump, oil pump, and oil cooler.

This should provide you with around HP. Beyond that, GTR rods, forged pistons, uprated head gasket, ARP studs, and head porting will need to be on your agenda. If you plan to go full retard, you can source an RB26DETT head and one of the off-the-shelf stroker kits to achieve a displacement of around 2.

If you look at the displacement, this may seem like an unfair comparison, however, there are advantages and disadvantages to using both these engines, which are both commonly used for swaps. If big power is your intention, perhaps for drag racing and even possibly drifting, then the RB25DET is most likely going to be the better choice due to its power capabilities.

Both have their advantages, and realistically it all comes down to personal preference and whether you have a spare engine lying in the garage! This is the battle between two of the most popular 2. Both engines are very similar in size, roughly the same bore and stroke and the head stud and bearing thickness are also roughly the same.

This video showing the testing of two randomly sourced blocks was insightful for this topic, which may sway your opinion slightly:. This has become an extremely common swap over the years, especially for KA owners. Given its popularity, there have become many off-the-shelf parts produced to make the swap easier than ever. The shaft features larger, replaceable and greaseable u-joints and can handle about WHP.

By removing the factory 2-piece shaft and installing a single shaft the car will feel more responsive due to the fact the hanger bearing is not moving up and down during acceleration. The handy premade RB25 S13 swap combo makes replacing both harnesses fast, easy, and affordable. However, all cars have issues, eventually, and given the age of these engines now, it should come as no real surprise.

In this case, owners are finding excess oil in the cylinder head and catch can, but not enough oil in the sump. There are several possible solutions, which include fitting an external oil return from the rear of the cylinder head to the sump. Oil surge can cause bearing failure if people overfill. Running more than 0. Additionally, the cam angle sensors do have a habit of causing issues from time to time.

There are plenty of solutions to the problem online but swapping it out is typically the best choice. Other than that, we have heard of various reports of electronic issues, as with all cars!

For the R32 M30, the bore was enlarged to 87 mm and increased the displacement to cc. The head was also replaced with RB26DE head.

Nissan did not produce this engine. It refers to a turbocharged engine using an RB30E short block with the twin-cam head installed from another RB series engine. The variable cam timing may be disconnected altogether. It may be necessary to reduce the size of the oil restrictors in the block and machine a full face oil pump drive collar onto the crank, to prevent it shattering at high RPM , with the use of a twin cam oil pump.

The fitment of a twin cam head from any of these engines onto a standard compression RB30E bottom end gives a forced induction friendly compression ratio around 8. However they have been known to reach engine speeds up to 11, rpm with extensive balancing and blueprinting. This engine was manufactured with a reinforced cylinder block and cylinder head, metal head gasket, pistons with cooling channels, forged crank shaft, forged connecting rods, N1 turbine with reinforced actuator, high flow intake, stainless down pipe, and low exhaust resistant sport cats, most of which were not offered for the RB26DETT.

There are many stroker kits available for RB Engines some only available as proper kits while others being achievable by using cranks from other engines, for example a GT-R crank, pistons and rods in an RB25DET will make its displacement 2.

Other than that, we have heard of various reports of electronic issues, as with all cars! However, given the age and how some of them are treated, it hardly comes as a surprise and could boil down to absolutely anything. There are many valid reasons as to why the RB engine series is one of the highest regarded, not only in the tuning scene but across the entire automotive world. If weight is an aspect in your decision, then it may well be worth looking into the RB20DET rather than completely ruling it out.

If money is no issue, then you may even want to consider going own the RB28DETT route for the additional rarity factor! There will always be superior engines on the market, but the RB25DET has certainly earned a worthwhile spot in the history books.
