Does anyone have 1.8 intake flange drawings?
 

Hey guys,

I am chasing some drawings of the 1.8 intake flange for both the 94-97 and 98-2005 engines. From what I can see the only difference is that the ports on the 98+ are positioned ~15mm higher than the earlier generation with all the mounting holes remaining in the same place. I haven't had any luck finding drawings but I guess that is to be expected given they would be in less demand than drawings of the exhaust flange. Can anyone help me out with this?

I have a ProEngineer 3D file for a 99+. I could convert it to a step or iges file if you can work with that.

I have dwg and dxf file for this flange i made using the oem gasket as a pattern as well as several 1/2" stainless flanges that i can sell, you can have the file if you like.

Good thing the intake flange is the same as the exhaust flange.

I have the 99+ in raw scan data, of the head, not the intake. Go with Midtenn, he has it all cleaned up 'n pretty.

I just emailed it to Leafy.

Thanks for the replies.

Midtenn a step file of that would be appreciated :) I will PM you my e-mail address.

HHammerly the image you linked appears to be the exhaust flange. Do you have drawings of the intake flange? If so I would be grateful for a copy. I am chasing both the low port and high port variants if you have them. You have a PM.

They look quite different to me, am I missing something? Was the scan done with a hand held scanner? I am curious how long it takes to get a detailed scan of items.

EDIT: Ok apparently I can't PM you guys due to having a low post count. I added you as contacts but it still won't budge on the 15 post requirement to PM. Are you able to PM me your e-mail addresses so I can send you mine?

Yeah, you're missing the sarcasm. ;)

I use a Faro arm touch probe to scan, not a laser. So it's relatively few points on a sketch.

Haha it makes sense now. Ouch, $40k-$85k for one of those. Do they have advantages over laser?

Midtenn even with adding you as a contact I still can't send you a PM without having =>15 posts. Can you please send the step file to: e-mail removed.

Does anyone know the port offset between the low port and high port heads? From this picture it looks to be around 15mm.

Yo Midtenn, any chance I can get that step file off you?

Thread drift ahoy!

We've had a couple vendors come in and demonstrate their laser scanners, including Faro's add-on. The laser is very pretty and gives you info if you are making organic shapes, which we aren't. The laser is not as accurate as the touch probe, nor as quick if all you need are geometric feature locations. For example, if all you want is the location of a hole, you create 3 points around the hole with the probe. With the scanner, you spray the part with powder because the laser can't scan shiny stuff (dirty, takes a while), scan it (quick but definitely longer than clicking 3 times), then use fancy expensive software like Geomagic to have it recognize the feature, then try to remove the powder from all the nooks N crannies. This takes a lot longer than clicking 3 times with the probe and what you get at the end isn't as accurate or repeatable as the probe. That's what we use our Faro arm for, digitizing engine blocks and cylinder heads for valve & bolt hole locations, etc.

Hey is there a place which hosts the dxf's for all of the common miata flanges (I would like 1.6 exhaust asap infact)?

:)

I never got your email address. Send me an email to ishroadkill[at]hotmail.com and I'll send it

That makes sense. The right tool for the right job I guess.

I have sent you an e-mail, you may want to remove your address from your post.

Its a junk email catcher for me really. I'm not too worried about it. I'll send the file tomorrow.

Midtenn
I also emailed you about the flange. Thanks!

Thanks Midtenn. The file imports into Solidworks with no issues. I am already playing around with manifold designs :)

No problem.

Another email sent. Also happy to PayPal some beer money in return for your generosity...

With permission from Midtenn, I'll leave this here for at least a little while. STP file for '99 intake flange...

I downloaded this file.

I have autocad, but not solidworks/proE.

Is it possible to convert it to a DWG file?
