It's also a 20mm thread. Linked above the picture is this thread: Don't Use Nissan OEM Oil Filters (Long Post - Lotsa Pics) - MyG37

Read it...Very interesting!

Increasing the oil volume has nothing to do with the pumps ability to pressurize the oiling system other than to keep temps down and therefore viscosity up. Cooler, higher viscosity oil will typically show a higher pressure were you to put a gauge on this.

^^^ right but you will see a drop in flow rate.

Interesting about using a longer filter. This inspired me to xref the K&N filters. Looks like, their model HP-1010 is the equivalent. The specs are identical to the HP-1008 some of us are already using except that it's about 7/8" longer.

I have no idea how our (or other) oil pumps are designed, but I would think depending on the pump design you would either see a drop in flow rate (from moving a larger volume of oil using the same force), or an increase in oil pump 'drag' on the engine but same flow rate (in the case that the pump is designed to move a fixed volume per stroke/rev/whatever regardless).

Modshack,

Nice install and a very nice writeup. It should prove valuable to many on the list.

Heh heh.... you never know. With your persuasive indoctrination skills, you may end up seeing more of me here. At least I didn't buy a Vette! :rofl2:

I would think that the limitations in pressure and flow would be determined downstream of the filter and cooler, limited by Bearing clearances, oiling orfice sizes, the relief valve, viscosity, heat levels, thermal expansion etc. Once the system (cooler and filter) is pressurized the factors just listed will determine pressure and flow. There will naturally be less flow and higher pressure with cooler oil. This is mentioned in the service manual when testing on a cool engine and anyone who's ever had an oil pressure gauge on a car can confirm by observing pressure drops as an engine comes up to temperature....The VVEL failsafe system seems to be sensitive to pressure but is triggered by temps as it is assumed pressure and viscosity drops with extreme temperature rises (see graph at the top of my DIY)

Many thanks! :tup:

Hey Steve...

Thought I'd shoot up a quick comment. Not sure if you and I have ever discussed my Ghetto Grommet program. I used it when we put the Comptech supercharger and aftercooler in the S2000. The aftercooler had water lines that ran to a pump in the fender. You may already do this, so if it's a *R* epost, sorry. ;)

Since I'm paranoid of rubber hoses chafing on anything, when I cut holds for them to run thru, I usually go a tad bigger than I need, then make a grommet to surround the hole. I just cut some 1/4 inch rubber hose lengthwise, then wrap it over the cut edge of the plastic/metal that I cut a hole in. I drill a few small holes and then use zip ties to hold the Ghetto Grommet in place. Then I run the hoses thru so it's rubber on rubber instead of rubber on "anything else".

I even use this method in the reverse when running braided stainless line to keep it from sawing thru things. I use a piece of hose slightly larger than the stainless, wrap it, zip tie, etc.. Have a few of those on the STi now. Just thought I'd drop that one here.

You can just barely see the gray hose on the driver side of the aftercooler in this pic. There are two of them that run out of the bottom side of the aftercooler and down into the left front fender under the headlight. An our and return. Russ Scott and John LZ7W helped me with the routing/install/etc.. Good times.

I searched my Fotki acct but couldn't find any pics of the actual Ghetto Grommet, but I'm sure you get the idea. Now I've gotta look even closer at the 370Z since you're playing with one. Not sure if this here forum knows how much of a lottery they hit when you landed here, but sure they will soon if not already. :tup:

Any VTDA's out here yet??:icon17:

Brad! Good idea...I was actually looking at that yesterday and planned to do something similar. Seems a few short lengths of slit 6mm silicone will do the trick. Having had a stainless line saw through a power steering hard pipe once I know what you mean! As an expansion of that idea, I think laying a bead of clear silicone inside the split tubing would be super clean and alleviate the need for Zip ties while still holding the "Grommet" in place..
Thanks for the :tup: Haven't started playing with the intake yet, but you can bet the wheels are turning!

Good idea on the silly-cone. Yup, I'll bet they're turnin'! :stirthepot:

With the extra oil and the thermostatic switch set at 180 is there a need for a windage tray and new dipstick?

No....There is no change in the level of the oil in the sump as the additional 1 qt. is carried in the lines and Cooler core. Nothing has really changed...You are just providing an additional cooled path for the oil to flow from Pump>to Cooler>to Filter>to Engine>Back to the sump

i bought a long oil cooler (according to baker precision, they're the same as tru-cool) years ago for my 240sx, but lost my car in an accident before i could install it.

Long / Tru Cool Oil Coolers

according to one of the guys at baker, the setrab uses a fin design "a lot better" for cooling. the tru-cool/ long is sturdier, but not as good at cooling.

he didnt sound that convincing....

what do you guys think?
