Has anymore ran a ls/vtec oil line kit on their all motor gsr motor?

Does it reduce wear? any issues from running too much in the head?

Pros and Cons?

 

think about your question here.. You're trying to run an LS/VTEC kit on an engine that has nothing to do with an LS.

Are you referring to the use of LS Crank/Rods in a GS-R Engine block? please elaborate

 

??

 

I think maybe he's saying running the oil line to the head but there's no point for that

 

complete gsr motor just wanting to run additional oil pressure to the head.

motor is running jun 3's with high compression setup

 

No there's no need to

 

I am running an external line on my motor not sure if it really is helping me or hurting me but I can tell you that everytime i pull the valvecover off there is no lack of oil anywhere.

i read on endyn's site where its recommended on reg vtec motors so I had the extra fittings and lines lying around and went ahead and did it.

 

I run external oiling on ALL of my high RPM engines... As long as your oil pressures/flow are in check (which they should be if you built your engine right), there will be no adverse affect from running an "LS/VTEC" kit on a GSR. This will also help with the wear on rocker pads (in conjunction with using the correct oil) as well as potential journal wear. You guys are misinformed...

ENDYN recomends this for big cams...to help with wear..

 

Just some food for thought:

A good external oil line kit will use a -6 hose which has an ID of .375"

The deck of the head has to be drilled, then tapped to fit a 1/8" pipe plug. The drill used for doing this us typically about .3302".

By very basic logic, the stock oil feed hole in the head is less than .3302" in diameter. I would guess, as I don't have one here to measure, that the stock oil feed hole in the deck of the head is about 8 mm in diameter.

area for 8 mm hole = 0.0779 in^2

area for a -6 hole = 0.1104 in^2

That is an area increase of 41.7%.

I dunno about you guys, but if I am going to run an aggressive set of cams, I sure as hell want the most oil volume I can get to the head.

There are very rough numbers as I don't have anything in front of me to verify though, so take it with a grain of salt?

 

The head uses "X" volume of oil, by increasing the diameter of the feed, it slows the velocity of the oil entering the head. At the end of the day, the same overall volume will be pumped through (assuming you havent hit the limit of the hole).

The head has specific oil points (journals, through the rails above the rockers, vtec solenoid, etc). So as long as the primary feed has enough volume to feed all of those, then you are fine. Even in a "high revving" or "high horsepower" application those oil points are still the same diameter. So as long as you have 75psi going to all ports, adding another "feed" isnt going to change anything. The same amount of oil will be feed in through the engine (not due to the feed into the head, but the actual oil journal ports).

Bottom line - even with a stock setup, all the oil feeds have 75psi pushing oil out of them...that isnt going to change due to a ls/vtec feed setup.

Also - who's seen a b-series run without a valve cover? Lack of oil is a funny thought.

Maybe if you enlarged the oil ports on the head, then you would need to run a larger feed....ofcourse you could also replace the bypass spring in the pump to run a higher psi for more oil as well. So many options.

 

While all this is true - pressure shouldn't be fixated upon. The problem is a little thing called VTEC. Also, pay attention to the previous post mentioning flow and pressure. You must have never of heard about "oil wiping" from higher lift cams either?

when I did my external line I didnt block off the hole inthebottom of the head did think I needed to becuase I am running a vtec setup, but I am having problems with vtec not engaging I am going to pull the external oil feed off today to install my oil pressure guage maybe this is one of my issues is to why vtec will not engage.

 

It never hurts to check the oil pressure, but where did you run your external line from? If it's unfiltered it will plug up the solenoid spool/screen fast.

PS - I have never purchased anything from Endyne or ENDYN, ever.

 

I stepped up the hole size slightly in the head oil control orifice for this exact same reason. A little more oil volume to the head is a good idea to me.

 

I pulled my extra external oil feed line off today and just put the plug back in the head and took the the t fitting off the back of the block and installed the oil sending unit and I do believe that fixed my problem. i think using the external line in conjunction with the stock feed to it lost just enough pressure not to let vtec engage.

 

Good deal. I didn't think anyone would try using both, but it is good to hear that you may have solved your issues. Time for some updated power numbers.
