Fire Extinguisher : Nissan Skyline GT-R

H3R Performance Universal Fire Extinguisher Bracket in a R32 GT-R

If you have ever had a car catch on fire, you know it is a scary thing. There is a point with every fire that no amount of handheld fire extinguisher will help.  However a small handheld extinguisher deployed quick enough can extinguish a fire.

Without getting into too many details, there are four main types of fires. A,B,C, and D.  Each has an extinguishing agent that puts it out best.  There are pros and cons to each.   Most cars you are going to normally have a burning liquid, oil or fuel, that will also burn some materials. So a class B,A fire. B being a burning liquid, A being paper, carpet, that kind of thing. C being electrical, so a non conductive agent. D being a burning metal.

Oil Pumps on RB Series Engine : True or False

Tomei oil pump vs OEM oil pump

True or False?   The oil pump on an RB series engine will explode if you look at it funny?


Like any vehicle, any mechanical device, there are some flaws with the RB oil pumps. If a car was running for 25 to 27 years with the original engine, original oil pump, and it breaks in a week once a new owner has it, it might not be the car.  There are people out there that believe the pumps are made from glass, which they are not.  For the hundreds of thousands of RB powered cars in the world, there are relatively few failures, but they do fail.  Generally if they fail it is due to over revving, or shocking the oil pump.  The oil pump is driven directly from the front of the crankshaft. It has to suck and push oil, something pumps don't like to do.  At 8k rpm stock, the rev limiter protects the engine on the way up, but not on the way down. Right hand drive car in a left hand drive world. Don't misshift like these guys...

Our NISMO R32 is an early car, with an early oil pump and drive. It has several track days turning 8000+ RPM, and several drag strip days coming off the two step.  We went through more clutches than engines or oil pumps.

Often new engine builds have an oil pump failure. Most of the reason for this would be related to poor engine cleanup, or poor installation. We have seen the blocks align honed, then the oil pump not be squared up to the crankshaft. Since the oil pump is not centered on the crankshaft, it binds on the housing with every rotation. Eventually this causes a failure. We have seen several oil pump gears showing signs of blueing, which will come from poor install. If the engine builder doesn't know what he is doing, of course he will blame the engine, rather than his lack of knowledge.  If you are installing a new oil pump, make sure you check the crank for binding once the oil pump is installed.

If you are just driving the car around normally, you change the oil, then no reason to be concerned. If you are two stepping at every car meet, pulling 9k rpm, and 35 psi, then an oil pump upgrade is probably in order. Not every car needs a Tomei pump, not every car needs a spline drive, not every car needs a dry sump.  At the low end you are a few hundred dollars in parts, plus engine out labor to get at the pump. At the dry sump end you can be near $10k in with pumps, lines, fittings, pans, filters, belts, and brackets. What you need for your setup, is up to you.

There are several reasons for oil pump failure not related to driving, laid out below.

Nismo #500, and the Vert
Why do the oil pumps fail?

  1. Installation error. If the pump is not square to the block and crankshaft, it will bind with every turn of the engine. We have seen several failures related to new builds, align honed, and the pump dowels not being modified to ensure the gear clearance is correct. 
  2. Cavitation at the inlet side of the pump.  High RPM, long draw. Pumps only like to do one thing, suck or push. You are asking it to do two, which it doesn't want to do. 
  3. Bad design. The flats of the drive are at the small side of the gears
  4. Going oval. We have seen the gears go oval. Mostly related to install, and cavitation. 
  5. Backing plate screwings coming loose.  The backing plate screws can come loose causing a loss of oil pressure. Loctite or stake them in place when assembling engine. 

Oil pump drive

There is an early and a late oil pump drive.  The early drive only very minimally engages the flats on the oil pump gear to drive it.  You can see when Nissan went to the later style pump that the width and engagement about doubled. If you have an early crank, you should think about swapping the crank out for a later crank, or purchasing a crank collar.

Early oil pump drive
Early drive- Notice how much smaller it is than the late drive. Also notice the small shiny spot. That area is the only part that actually engages the pump.  

Late oil pump drive

Late drive - Notice the wear on the flat spot. Compare the width here to the early drive shown below.

Oil Pump Gears Going Oval

This is something that we noticed fairly recently with the oil pump gears on the RB26. The inner gear on the oil pump has two flats that are driven on the crank. We noticed that we had some oil pumps that were binding. Measuring at the flats and the opposite side to the flats, the gears appear to be going oval. We have seen it in a JUN oil pump, and a Tomei oil pump.  Both pumps, when the gears were replaced with Spline drive gears, no longer showed signs of binding in the housings.

Brand New 2002 Nissan Skyline GT-R Vspec II Nur sells for 35,200,00 Yen

2002 Nissan Skyline GT-R Vspec II Nur
edit - 35,200,000 yen including buyer premium.  $317,000 USD

A brand new, as in 10km R34 GT-R Vspec II Nur sold at BH Auction in Japan for 32,000,000 yen(~$288,000). That is not 10k km, but 6.2 mile car.

BNR 34 type which is the final evolution model of the second generation GT - R was first demonstrated at the Tokyo Auto Salon in January 1999. In the full model change from the big hit BNR 32 to the predecessor BCNR 33, I was criticized for the bigger body, the weight increase, etc., BNR 34 made a slimmer. Compared to BCNR 33, the length is reduced by 75 mm and the wheel base by 55 mm. At the same time, the whole width was expanded by 5 mm, and exercise performance was improved. 
Although the engine is a traditional RB 26 DETT, the point is that the turbine bearing has been changed from a metal type to a ball bearing type. This is an improvement aimed at improving the response, together with boost pressure boost and ECU optimization. While the maximum output was 280 ps, ​​the maximum torque reached 40.0 kgm of the BCNR 33 ratio plus 2.5 kgm. 
Moreover, in the power train, the transmission changed from the Nissan in-house manufactured 5-speed MT of the former model, and in BNR 34 it changed to the 6-speed manufactured by Getalg.Brembo caliper (F: 4pot R: 2pot) was equipped as a standard brake.In addition, in the V specification, the Atesa E-TS PRO including an active LSD that positively performs the differential restriction of the left and right rear wheels according to the situation is adopted.

After that, in 2000 V minor change appeared in V Spec Ⅱ equipped with NACA ducted carbon hood. Contributing to reduce understeer by suppressing the weight of the front axle. Also, in 2001 M-spec that pursued comfort as GT appeared to overturn the conventional GT-R image. Adoption of a dedicated damper realizes supple ride comfort. 
Such BNR 34 also becomes difficult to respond to the exhaust gas regulation, and is stopped production in 2002. As a final edition, "Nur" was sold only for VSpec II and M spec for 1000 units (originally announced at 500 units, increased production at the request later from customers). 
Based on the reinforced block, the engine is balanced and each unit is equipped with an N1 engine incorporating a metal blade turbine.It also boasts content that can be said to be the last-minute beauty of the second-generation GT-R, such as the adoption of a dedicated 300 km / h full-scale speedometer, making it the most valuable model as a collectible car among the BNR 34. 
This individual is an unregistered new car that can also be said to be a vision, the mileage displayed by the odometer is only 10 km.Among the V specs Ⅱ, the final limited model "Nur" is a priceless one, and "Nur" based on the more spartan V specifications Ⅱ is more valuable being sold for about 300 units. The engine is a N1 specification with exclusive color gold, the interior is the finest thing to keep "new car condition" enough to touch you.
