So continuing with this flange..
Trace a rough stencil. https://www.miataturbo.net/attachmen...ine=1374592062 Double check you have a hole saw that matches the turbo. https://www.miataturbo.net/attachmen...ine=1374592062 Connect the edges with straight lines, this will be cut with an angle grinder. https://www.miataturbo.net/attachmen...ine=1374592062 Looking ok. https://www.miataturbo.net/attachmen...ine=1374592062 Tidied up with sandpaper. https://www.miataturbo.net/attachmen...ine=1374592062 Now it looks alright. https://www.miataturbo.net/attachmen...ine=1374592062 Tonnes of spraypaint, note that I took the turbine housing off to do this. https://www.miataturbo.net/attachmen...ine=1374592062 Now we have a flange shape, we can holesaw the centre out and build a downpipe. https://www.miataturbo.net/attachmen...ine=1374592062 Dann |

Holesaw your holes.

So a box of bits arrived this arvo 8)
https://www.miataturbo.net/attachmen...ine=1374592108 So Ive tacked the turbo to the manifold, for some test fitting and the downpipe build. https://www.miataturbo.net/attachmen...ine=1374592108 The vice will be used like this to shape the pipe initially. https://www.miataturbo.net/attachmen...ine=1374592108 This little guy is the water return for the in cabin heater, it always gets in the road of a good downpipe. https://www.miataturbo.net/attachmen...ine=1374592108 But with some gentle persuasion, it easily bends away for a little more clearance, this is standard practice on turbo NAs. https://www.miataturbo.net/attachmen...ine=1374592108 I dont suggest consulting the warranty handbook for the vice before doing this, it wont help :P https://www.miataturbo.net/attachmen...ine=1374592108 I know its ugly now but let me weld it and tidy it and away we go :) https://www.miataturbo.net/attachmen...ine=1374592108 Dann |
this thread got better; thank you.

I have boxes of flanges but this one is a fraction different than a 25/28 one... Such is life.
And Ive been doing this too long to make mistakes like this :lol: Ah well, whats half an hour out of my life? :P https://www.miataturbo.net/attachmen...ine=1374592170 Dann |

]Big update time.
Tacked a couple of bends to the downpipe, this routing gives a LOT of clearance for working on the car. https://www.miataturbo.net/attachmen...ine=1374592248 Here is a reducer cut in 2, this was 3>2. Now its a 3>2.5 and a 2.5>2. https://www.miataturbo.net/attachmen...ine=1374592248 This demonstrates how it will work to bolt this to a stock 1.75" system, this car has a 2". https://www.miataturbo.net/attachmen...ine=1374592248 Nice flow. https://www.miataturbo.net/attachmen...ine=1374592248 Performance is all about the details, the die grinder is used a LOT when doing custom piping. https://www.miataturbo.net/attachmen...ine=1374592248 From top to bottom, 2" flange, 2>2.5" 316SS reducer, 2.5" SS straight, 2.5x6" SS flex pipe-double braid for flow. https://www.miataturbo.net/attachmen...ine=1374592248 Tacked to the rest of the downpipe. This took 2 goes to get the flanges lining up to the millimetre. https://www.miataturbo.net/attachmen...ine=1374592248 Nice straight path. Installed, tucked up nice and high, 100% above the frame rails. https://www.miataturbo.net/attachmen...ine=1374592248 Getting started on the crossover pipe. https://www.miataturbo.net/attachmen...ine=1374592248 Path. Nice and short. https://www.miataturbo.net/attachmen...ine=1374592248 Throttle body side started. https://www.miataturbo.net/attachmen...ine=1374592248 How it all sits on the car, needs another 2.5>2" reducer and AIT bung for the MegaSquirt ecu, and the tube for the Idle Air Control (IAC valve). https://www.miataturbo.net/attachmen...ine=1374592248 Dann |

Blurriest photo ever as it turns out.
Dont worry theres a nice weld under there :P https://www.miataturbo.net/attachmen...ine=1374592357 This is the Idle Air Control port. Dann |

Heres where we are up to, need an oil feed line, air filter, finish the pulse welds, drill the sump, bolt it together and clip the megasquirt in and tune 8)
This update is very pic heavy and helps explain SpeedFlow type fittings and their assembly. This flange, for some reason out of like 10 I purchased didnt come tapped, so a trip to the bolt shop and 20 bucks later its tapped. https://www.miataturbo.net/attachmen...ine=1374592404 Use a square and eyeball the tap is vertical. https://www.miataturbo.net/attachmen...ine=1374592404 So here is the oil feed line, on a garrett this is a gas fitting, Ill feed this with a hardline from the head, any brake and clutch shop can make you this hardline for 30 bucks. https://www.miataturbo.net/attachmen...ine=1374592404 This is the oil return, much larger. https://www.miataturbo.net/attachmen...ine=1374592404 This particular turbo has an incredibly unusual fitting, Totally unavailable from SpeedFlow, 13 bucks later after a trip to an industrial hose shop I got a 22mmx1.5mm internal flare to -10JIC fitting, now back to the hotrod shop for a Speedflow adaptor and hosetail. https://www.miataturbo.net/attachmen...ine=1374592404 So with liquid threadtape, it gets screwed in. Use a spanner for final assembly. https://www.miataturbo.net/attachmen...ine=1374592404 Then the JIC to -10 adaptor. https://www.miataturbo.net/attachmen...ine=1374592404 Then the -8 hose tail. https://www.miataturbo.net/attachmen...ine=1374592404 The hose gets pushed down hard like this to fit it on the barb. These barbs are high pressure and dont require a clamp, but I'm using one anyway. https://www.miataturbo.net/attachmen...ine=1374592404 Cut a clean straight end from the hose, in this case we are using -10 heat resistant fire retardant efi capable hose. https://www.miataturbo.net/attachmen...ine=1374592404 Then into boiling water it goes to soften it. https://www.miataturbo.net/attachmen...ine=1374592404 Some lubricant, use soap because it will dry up, unlike oil. https://www.miataturbo.net/attachmen...ine=1374592404 This collar must be on this direction before fitting the hose, this makes it look nice and tidy, THIS IS YOUR LAST CHANCE. https://www.miataturbo.net/attachmen...ine=1374592404 Push down HARD. In ONE motion. There are no second chances these barbs do not let go. https://www.miataturbo.net/attachmen...ine=1374592404 And a hose clamp because insurance is always recommended. https://www.miataturbo.net/attachmen...ine=1374592404 Not long now!

Alright, here we go, the most fun part (not even slightly, and they dont get any better).
Drilling the sump and tapping it. And the first few are of my porting the manifold. Here is the unported manifold. Horrible photo sorry. https://www.miataturbo.net/attachmen...ine=1374592442 Half ported. https://www.miataturbo.net/attachmen...ine=1374592442 Inlet ports getting done next. https://www.miataturbo.net/attachmen...ine=1374592442 Crossover pipe welded. https://www.miataturbo.net/attachmen...ine=1374592442 https://www.miataturbo.net/attachmen...ine=1374592442 https://www.miataturbo.net/attachmen...ine=1374592442 https://www.miataturbo.net/attachmen...ine=1374592442 Downpipe welded. It has a double braid flex pipe for reliability. https://www.miataturbo.net/attachmen...ine=1374592442 Drill a pilot hole for the oil return. This location is NOT the tradition (ie miataturbo wiki) location, the miataturbo location is suggested because its hard to hit the oil pickup pipe and puncture it from that location, Here im just using experience and care to ensure it doesnt happen, we will look and test for it later. https://www.miataturbo.net/attachmen...ine=1374592442 Hole has been drilled with a bit usually used to countersink screw heads, its called a countersinking bit. It eats the alloy like its nothing. You can see inside the hole the oil pickup running horizontally, its close here but Im being SUPER careful with depth. https://www.miataturbo.net/attachmen...ine=1374592442 This is a 3/8 BSP tap and hand tapping piece, Ill be tapping with a ratchet not the hand tap (the 2 black bits, make a 'T'). https://www.miataturbo.net/attachmen...ine=1374592442 ALWAYS check the threads are the same by holding them in each other, this trick works for all bolts, you will know if its not right the threads simply wont seat. https://www.miataturbo.net/attachmen...ine=1374592442 Lets tap. Again being very careful to mark and check the depth. https://www.miataturbo.net/attachmen...ine=1374592442 Awesome, we have return. https://www.miataturbo.net/attachmen...ine=1374592442 After flushing the sump with degreaser this came out, its very important to flush the sump after tapping. https://www.miataturbo.net/attachmen...ine=1374592442 So after I had done this I unclipped the injectors and ignition harness and hooked up a battery charger. I crank it and check that it makes oil pressure just off the key. It gets to 2 on the guage, this confirms the visual inspection that the oil pickup is not damaged. if you cut a hole in it the oil pump will suck air and you will not have pressure, this is why it must be tested with the starter motor. Now Ill clean up the flange faces, add gasket maker, and bolt it together, with sealant on all of the threads. I must add an oil feed, and clip in the megasquirt, and put my wideband on for a tune, then we go for a slow safe tune, making sure the mixture is very rich and taking it very easy on ignition timing, and see how the car goes. Then its off to its owner over the weekend and he can enjoy it for a little while while he waits in line for a quick dyno touch up. Dann |

So this came in the mail, one from Gosford and one from the States.
This is 1000 bucks all up, the new Megasquirt PnP 2 for na6, an IAT bung and sensor, the cables and software, and the unifilter, which is much larger than I expected.. https://www.miataturbo.net/attachmen...ine=1374592468 Dann |
AND THATS WHERE I AM UP TO IN THE OTHER THREAD.
The next updates will be live. Dann |
Dude, you are aware that -10 JIC is the same as -10AN you have a superfluous adapter. Shit I'm surprised they even sell a JIC to AN adapter.
|
Fittings confuse me, metric to imperial and back again is a real headfuck for me, especially with AN and JIC and adaptors with codenames you have to remember, but Im certain that the adaptor is necessary.
Dan |
Trust me. If that is an M22 to -10 JIC adapter, you can screw your -10AN push to connect fitting right on it.
|
Yeah but I dont think it has -10 hose, it has -8 hose, so it has the adaptor first.
I just gave the fitting I got, and the hose I needed to the hotrod shop and purchased the SpeedFlow fittings. Dann |
the difference between AN And JC is trivial, it's just the degree angle of the "flange".
