Oiling systems are very important to any and all engine types and setups.  My focus with the Nissan platforms is to take whats already available and find their weak points and tackle them to make them better.  Cooling by way of oil is a very important aspect of engine life and sustainability.  Overall, if you can keep your outfit running more efficient and better cooled your engine will out perform others and do so consistently.  For years manufactures have outfitted turbocharged and or supercharged engines with oil piston squirters.  Their function is to spray/stream oil to a designated area under the piston to cool them down.  The oil there by absorbs some of the heat and carries it down to the sump.  Oil on some outfits is then pumped to an oil cooler where oil has a chance to really cool down and return to the engine for more work.

The VG30DE series engine has oil squirters outfitted in the block (3) feeding off the main return oil galley.  The OE squirter is a split design and covers 2 pistons at the same time.  Nissan developed 2 different styles, one for the twinturbo outfit and the other for a non turbo setup.  The two are the same but slightly different in spray pattern.

(The “cleaner” (new looking) oil squirter is the NA one and the TT one is the oil stained one)

So where do we look now?  Well its always a good idea to keep your parts running cool right?  A new idea was envisioned and a drawing was made.  My idea to further the oils ability to cool the piston was finally down on paper.  With the continuing effort to produce more HP and TQ the engines see more heat and stress.  So there has to be new efforts in coping with these new temperatures and stress levels.  The idea is to control the oil on both sides under the crown of the piston there by allowing the oil to absorb as much heat as possible.  Aiding in preventing detonation and improving the engines ability to keep cool under heavy load and conditions, this new development hopefully will bring new ways of keeping high performance VG30s alive longer.

This is not the final version of this oil squirter, but you can see what development is being done.  I am continuing work on this and hopefully this year I can have a set of 3 to run tests with.  Stay tuned!  More things are soon to show up, so check back periodically for more details and information on other exciting products and services.
