Just for your (general) information...

If you ever decide to get an aftermarket oilcooler, you can get a 22mm female coupler and have it convert to a 3/8 inch hose for most aftermarket oilcoolers. The 22mm female coupler will fit on to the quick disconnects which come from the stock oilcooler itself. The ones im talking about are the male ones on the oilcooler itself which can be unscrewed. I recently learned this after months/years of asking and no one knowing this/having a clue so if you wanna buy mocal (this is the brand that crooked willow racing uses which cost quite a bit, i think about 800-900 bucks) oilcooler itself instead of the kit which easily cost like 2-3X or more then the amount of just the oilcooler itself which can be bought anywhere and restricts the size of the oilcooler (hell, you can get one as big as a fmic and mount it as a FMOC;front mount oilcooler, if you wanted), now you know how to do it

BTW: If you guys can't find the 22mm coupler and reducer to a 3/8 inch hose (of if you want any other type of reducer to anysize you need just about), I can help you find it. Just PM me or email me and I can hook you up

 

Thanks. Useful info for my latest project

 

Much of the cost for the CWR oil cooler kit is in the thermostat, lines, fittings, adapters, ducts, and brackets. The coolers are available for $270 or so for a pair without looking too hard. The ducts and brackets would have to be custom fabbed if you don't get the kit. I added it all up when I bought the kit and decided it was worth the cost to me.

You can't get the kit anymore, AFAIK. Rotary Extreme has some kits. The fittings to connect to the front cover and to the oil filter pedestal are available in steel from Mazdatrix for not too much money (much less than the aluminum fittings that are available elsewhere). The rest of the plumbing is standard AN10 stuff. The Mocal thermostat and coolers are available from PegasusAutoRacing.com.

Is 3/8" hose really big enough to put the whole oil supply through? That seems very small to me. AN10 hose is twice the diameter and four times the flow area.

for hte oilcooler im using for one of my fd's it seems to only take 3/8 inch tubing. Seems ok

 

oh, and the inside diameter for the pipe comming from the engine (the hard pipe lines) are damn near 3/8 inch, they open up to a 5/8 inch line which is the thick hose...

so the thing you gotta ask yourself is, will the opening going to a 10an hose and then shrinking back down to a 3/8 inch hose really make that much of a difference. personnaly i think the type of oilcooler will make more fo a difference!

oh and another thing you might wanna thing about is that the big lines go down to a 3/8 inch hose thru the quick disconnect (even for the stock oilcooler) so you gotta be figuring that in to the equation!

In the end, if you think about it, it dont really matter

BTW: how does 6an or 10an fitting convert to inchs?

 

I believe AN was a standard developed by the navy that is sort of metric inches (base 10 but on inches). 10 AN = 1", 6 AN = .6", etc. (of course I have no idea why I think that and google couldnt confirm or deny that guess) but it should be easy to confirm if you measure some AN fittings.

As far as the debate on the best size hose to have I would go with 10 AN because having more flow is better and while there is certainly going to be a restriction somewhere why make it in the hose?

got some new info, a 10 AN fitting/pipe/line would be .469 inchs there for a 3/8 inch would be between an 8-10 AN line and there for not really that small (in fact damn near the same size pretty much).

just wanted to follow up on a bit of info

 

AN stands for Army-Navy (Poor Air Force got left out, I think this was before there time)

The size is the ID in 16ths.

ex: AN-10 fits over a 5/8 Steel Tube
