Been at the shop all day
but then again we always are between swapping auto trannies between two cars and battling a horde of black widows (we've found 5 so far) we managed to work a little more on the block I cut the remainder of the stock to size and been flycutting them for the last couple of hours have about 13-17 workable pieces hope we don't loose to many during set up and mock this up Quote:
and it's being a bitch don't know yet whether putting two straight 10AN fittings perpendicular to the block is doable since the oem put the oil in and out passages so close to each other. Mike seems to have an idea so we'll see. May end up having to use fitting with bends I hope not since these are usually more $$$ we'll do what we can this weekend and probably go have a chat with Earl's on monday. |

So he started cutting before he completed the design?
Hmm.. I would not use 90 degree elbows. Why would that be necessary? On the return part, you can have the oil dump in and channel back to the block.

I think you should just tell me what CAD software programs you can use on your cnc and I'll throw him a design he could at least entertain the idea of constructing. haha
I DO have machining/design experience..

The dimensions of 10AN fittings make it difficult to put them close to
each other. We also have to make sure there'll be clearance with the surrounding bits ie...starter, mount, intake support bracket, etc we also need to make sure sensor senders are in the clear we usually make parts in stages to solve issues with set ups and tooling and whatnot not unusual for us one bit to cut a detail while still working out another this is usually the hardest most labor intensive and expensive part of manufacturing things once we figure out the puzzle then we can pretty much churn them out anyhow, first lot deburred with block face detail if you look closely you'll see we modified the original design for better flow and clearance issues cnc cutting first batch deburred |

one of prices to pay for being unique... well we've been staring at the block for a bit today and tackling the fittings issue some more we think we may be able tp keep both fittings perpendicular to the face we'll see if anyone can post common pics of oil pressure sender units and oil temp senders that would help a little |

it's tight but they fit it's the 10AN hex profile that's the problem you need to clear that while it turns to thread aswell as the 7/8" socket required to thread it we are going to try using a 10AN orb adapter fitting the ones with the o-ring since it's a smaller depth than what a 3/8 or 1/5 NPT calls for remember the oil filter threaded part sticks out ~1" so the block needs to be at least that thick plus the fitting thread depth also it's easier to tap a 3/4-16 thread than it is to tap tapered NPT ones the oil flow channel isn't affected one bit thinking 1/8 npt spaced 90 degrees from each for the ports plenty of room for the sensor senders hope to have something to show by tonight *crosses fingers* |

Google and you can find a bunch of pics and details. I have a folder at work. I'll post the pics tomorrow.
I hope you left enough material to finish those pieces.

that center bore you have, is it going to be tight fit on the output shaft from the block? Do you have an o-ring groove?
Here is to show that all the sensors should be on the return port.. after the filter. Yes I'm bitter. haha, but I did all my homework. the -10AN fitting has a 3/8 NPT on the reverse side. I'm sure you guys know how to tap NPT threads?

now I know why no one makes a KA oil block
the placing of the fittings is a bitch it'd be so much easier to make one for the SR we hit a block yesterday with tooling and we're at work again today so it'll be a little while till we get some free time to spend on this again i'll update then |

hey, i didn't want to make a new thread with this stupid question... sorry to thread jack... but do you KA guys know of any reliable seller/company that makes a sandwich plate for KA... a friend of mine is looking for one that has a port for a turbo oil line...
thanks... oh btw i tried to convince him to wait for when you guys finished that adapter but no go with his cheap ass... |

Greddy sells a sandwich plate with extra ports in it. I'm using one for oil temp and pressure, with the oil feed in the OE block. There's knock-offs on Ebay but one of the ports is a 3/8" so you need to make a reducer bushing by tapping/threading a step down into it.
Could you guys increase the outer dimensions a bit to be able to fit both lines more comfortably? I figure once the base is sealed with a flange you can enlarge the rest of the body to accept more ports.

AN fittings can have just about anything on the other side. hell, we could even make our own custom ones again, reason why we're going to try using the fitting I mentioned is because the hole needed isn't as deep as the 3/8 NPT one. And yes, we know how to tap NPT threads. Quote:
We'll also check the rest of the clearance issues once we have a prototype and revise whatever needs be. If this doesn't work or looks like ass we may scratch this design and try one that uses one or two 90 degree fittings should help with clearance issues but would be more $$$. |

NO 90 DEGREE FITTINGS!!
And ya, do what Russ is saying about opening it up. I had enough clearance in my cad files. What Diameter are you using for the main ports?

Haven't forgotten about this
but it's the holidays and we're super busy with our own personal broken down POSs and work. Turns out the threaded part that comes out the KA block unscrews which allows for a much greater deal of flexibility in the design - this means that the oil block can be a smaller profile and won't need angled fittings just finished getting my friend's daily on the road again so I'm hoping we can squeeze some time during the holidays to work on this again. |

I've got a ghetto T fitting on my KA-T right now that I want to replace for reliability and consistency...
Shit sucks.
