Are you guys all using the V8R downpipes? Has anyone tried these? Cant imagine they'd be too hard to make fit, or should I just start with stock pipes and mod away?
Seems V8R downpipes are in short supply right now.

I made my own,,, turned out to be pretty easy. Squished a 2.5" pipe in a vice so it'd fit top to bottom in a CBM motor Sports flange. Welded the top and bottom locking them in place. Then working from the inside of the exhaust pipe, using a solid pipe and a hammer worked the sides of the pipe over to flush up with the flange, then weld it up. Toughest part was setting the angle of the pipe to the flange. As a sidebar,,, this is an FRS not a Miata.
What have you guys been using as a connector between the down pipes and the rest of the exhaust? I’d like to be able to disconnect
everything from the down pipes back. If the entire system is welded can you remove the down pipes from the head?

Do you have a link to a build thread for your FRS?
Ours is plumbed but we didn't charge it before winter, and now we're waiting to drop the engine to swap out the clutch before we charge it. By lower left you mean driver's side? What's hitting? The compressor body or the hoses?

Video is a pretty good way of seeing all the angles - this is the best photo I could find showing our placement (with a rope to mock up where the lines were going to be routed). I know V8R has A/C working on their NC - give them a call?

How are you managing the AC as far a clutch power, HP switch etc.??? Via the LXF ECU,,, or the Miata systems or some combination??
Right now its straight analog - from the a/c switch, thru the evap temp sensor, to the three-way mazda pressure sensor, to the clutch relay and the fan hi relay with a diode (so the clutch doesn't engage when the fans turn on). I may poke the a/c data some more and see if I can incorporate the ECM stuff once we have a working system.
Just as an update, on NC you can choose to have PS or A/C, not both utilizing LFX compressor and Mazda rack. There is a work around which I may delve into later. For now PS wins out.
Anybody have a belt part number if no A/C on LFX?

Thanks for the update. Think I'll try the same to start although I have doubts as I see the crank position sensor and the coolant sensor in the AC diagrams. I live in the sub-tropics and have to have some type of AC.

Not to be a complete PITA with questions LOL,,,, how did you end up plumbing at the compressor for suction and discharge lines?? I don't have any OEM's hoses to modify so I'm looking at this block to attach to. Not sure it'll fit though.
We snagged those blocks - and while they do fit the compressor, in our application they ran directly into interference. We ended up welding a hose end onto the stock camaro hose because it gave us the best clearance. Be aware there are 2 different models that point the hoses to the front or to the rear.
Ended up getting a block from Cold Hose. I did the straight. Looks to fit just fine,
On another note,, anyone do a remote clutch bleed?? The fitting in the slave is 8Mx1.25 which presents sourcing issues for a turn key product,, well at least as best as I can tell. There are fittings taking m8x1.25 to 3-4 AN but I don't know if the M8x1.25 will seal. Any thoughts???
ack, this ECU stuff is holding me up from fire in the hole. Thought I had the right thing but HP tuners software isnt happy with it.
here is what I ordered from Rock Auto
Apparantly it doesnt have a tune it it which makes alot of sense when I thnk about it, but I need to get an ECU with a tune in it. Anybody know what exactly I should get from the junkyard?
