OIL PAN BAFFLE PLATE  
When the vehicle is on the corner or the time of acceleration and deceleration, oil in the oil pan will lean or jump. To prevent these to happen, baffle is assembled in the pan of stock engine. Though, in terms of sports driving, it is almost impossible to achieve its purpose because the size of the baffle is restricted to cut down the production cost. If oil leans to one side largely, air goes in to the pipe instead of oil and interrupts continuous oil lubrication. Without oil, metal surface contact directly each other, then the temperature rises explosively and causing worn out if its lasts long. On the other hand, Tomei movable baffle plate is made to achieve stable oil lubrication at any situations such as curving, acceleration, and deceleration. And it will secure the improvement of engine performance from street use to the drag racing or circuit run.

OVERSIZED OIL PAN FOR RB26 (TUNING SERVICE)  


Compare to the SR20, oil delivery of RB26 must be done much more carefully because of its structure. However, RB26's oil pan is also used as front diff case and it has complicated shape. Since it is hard to make bolt-on kit, we take trade-inn modification service. IN our modification, while its total capacity is enlarged, height of oil pan is set equal as engine member in order to keep it from hitting damage. It is highly recommended to use this with RB26 oversize oil pump.

RB26 OVERSIZED OIL PUMP  

The RB26DETT engine is often plagued with oil lubrication issues during circuit and drag racing events which are the main causes of most RB26 engine failures. This problem causes the main bearings to abnormally wear out from the lack of oil pressure. The stock pump is not capable of supplying the adequate amount of oil to maintain the right oil pressures at extreme engine speeds that the high powered monster RB26 performance engines require. Another weak point is that the stock pumps gear is made from weak sintered metal and this often breaks when going for bigger power and higher engine speeds and when this little piece gives out can cause an instant loss of your engine. The TOMEI RB26 oil pump has a larger pump gear made of high strength materials to supply a larger flow rate to the engine and it has an external oil pressure adjuster as well.

OIL GALLERY ORIFICE  


The Orifice controls the amount of oil flow that is delivered to the head to lubricate the parts in the cylinder head and to cool down the engine assembly. However the stock oil-gallery orifice has a hole that is too large which allows too much oil to be delivered to the cylinder head which will cause the problems as listed below.

(1) Too much blow-by Gas,
(2) Blowing engine oil,
(3) Leaking oil through the valve guides,
(4) Insufficient oil delivery to the crank journal,
(5) Allows air pockets into the system from when the oil pan is under horizontal G-Forces.

The TOMEI oil gallery orifice was designed from the experience and data we had obtained from the development of our N1 endurance and drag racing engines. By restricting the diameter of the orifice to φ1.5mm (Normal is φ2.0mm) we succeeded in securing enough lubrication to the camshaft and valve while maintaining the correct amount of oil in the oil pan which resolved the common problems. (For added Blow by prevention, we recommend using the TOMEI 3D Profile pistons.)

SR20 OVERSIZED OIL PAN  
 
In drifting, circuit running or drag racing, the higher G forces of both vertical and horizintal will cause bad oil circulation due to the oil pickup not having adequate access to oil during cornering forces. This can cause engine failure if the lack of oil is a constant problem. We have developed this oversized oil pan for the SR20 and used it on our own N2 series Silvia race car in the past. Race proven with an extra 600cc increased capacity while not affecting the distance to the ground. With the added internal swing baffle plates will help with improved oil circulation.
     

2 piece partition swing plate design helps with the stable oil supply.

N2 OIL BLOCK  
The SR20 engine's factory oil block tends to fail due to the weak oil filter sensor screw which often breaks. We here at TOMEI had found the problem during professional racing over a decade ago, so we designed & produced this upgrade oil block which solved the problem. We had later discountinued this product after the end for the N2 series race but due to popular demand we had to bring it back into production with a new revived design. Now being lighter than before with ports for oil temperature and oil pressure sensors. The failure in the oil block can lead to engine failure so this is an absolute must have upgrade to protect your investment. Especially with vehicles running a sandwich block or similar the oil cooler can fail at times so you have to take added precautions.

EJ20 BAFFLE STIFFENER  
One of the main causes of engine problems on an EJ20 are the bearings. The majority of the causes of these issues are due to the lack of motor oil in the oil pan (sump) and passages. Also, the lack of rigidity in the crank case is also another problem facing this engine design. Under extensive research, Tomei Powered which decided to develop a product that securely remedies these problems. This baffle stiffener will help strengthen the left and right side of the crankcase to help provide the added support with its dual structural design. The rubber baffle design greatly aids the regulation of the oil supply. This gives added control to reduce blowby for EJ20 owners who use their cars for high performance driving.
* OEM setup with the oil supply problems. * With Baffle Stiffener fitted.

4G63 OIL THERMO KILLER  
One of the seldom-weak points of the 4G63 is the rise in oil temperature. It is seen more often in circuit driving. The EVO uses a thermo switch that will work when the temperature gets around 85ーC (approx 185ーF). Yet when the oil temp is low, it will restrict the oil flow to the oil cooler constantly regardless of the temperature. Still it is easy to revert back to the OEM switch for winter use to prevent over cooling.

UNIVERSAL OIL PAN BAFFLE PLATE  
 
A New Universal Baffle Plate That You Can Customize
To Suit Any Shape Wet Sump Oil Pans
The cars inertial forces from acceleration, deceleration and cornering will affect the oil in the oil pan. This can also cause the "windage" phenomenon from the sloshing of the oil in the pan. Controlling these problem factors are an absolute must on performance engines, to prevent terminal engine failure. When cost factors are in place, or sump upgrade restrictions apply, this is the best affordable upgrade on the market for your engine.
 
OILS BEHAVIOR IN THE OIL PAN
When the oil moves away from the pickup and air gets sucked in. In an instant, the oil film is cut and there is metal contact which will see the temperatures soar. This can lead to terminal engine failure.

The one way rubber valve keeps the strainer always submerged in oil.
