Im not sure who did this but Ive had these pics on my computer for a while now. Im pretty sure the manifold was for a GSR (B18C1), and that a BP flange mated to it pretty easily.

Wasn`t BEGi building a throttle body for the 1.6L motor?

Anyone know if anyone makes a BP Intake Manifold flange? I have access to a stock Axura Integra GSR intake manifold and a Type-R but I need some flanges to play. Our dyno arrives in March and this could be a fun project assuming I have time

So what's the most ghetto fab way to join the cut off miata bracket to the honda runners that would actually work? JB Weld? Aluminum brazing rod? Duct tape? Chewing gum? Or would this have to be welded proper.

you're the shop lol, why not cut the stock one off use it as a mold and make some new ones out of it

Hmm, us "great minds" think alike! I've been wondering if cutting off the Miata flange with about 2" runner stubs is a possibility. Open up the runner stubs to match the ID of the Honda manifold runners and then cut the Honda flange and about 2" of each runner off. Use 4 silicon hose couplers & 8 SS T-bolt clamps to physically join the Miata flange to the Honda manifold along with modifying/adapting the stock Miata intake manifold support to the Honda manifold so that the silicon hose connector tubes aren't holding any weight. Ghetto, but very functional. FWIW, Lycoming aircraft engines have logged millions of hours with these funking rubber/silicon connector hose intakes.

YMMV

WOW, thats rigged, but it seems like the same concept alot of the ITB guys use when adapting GSXR throttle bodies to the miata.

Almost all motorcycles use a similar setup...but of course the couplings aren't supporting any weight.

Vibrations would be my main concern, but if you could properly support the plenum I'm sure it could work.


I'm going to try to get mine properly welded. It hits the band saw early saturday morning (when no one is on the shop floor yet), and will dress it over the weekend and check out these local aluminum welders in the Woodlands to see what they'll charge.


The only problem with couplers I see is that the honda runners are not straight.

Our CNC guy will only do runs of 150 or more... I don't need that many flanges..... Do you???

Plus I don't want to hack up my OEM 2000 SE Manifold with 4 extra injectors.

Personally I would say it needs to be Aluminum Welded.. You don't want it to separate. I've seen an intake with silicone couplers fail as the engine basically hits the redline as there is no T-Body restriction.

I had a skunk2 ITR intake manifold on my B16 civic. It def. increased the power on the top end. You can find used ITR/BLOX/SKUNK/OBX manifolds for like $100 shipped. I wonder what improvements this would give for an NA application.

Find someone that will burn them on a laser or cut them out on a water jet. Probably much cheaper than a machinist (they like their work too much, haha). If we had any short run capacity at work I'd look into running them on our laser (we can run up to 1" tooling steel). The finish on a laser isn't going to be awesome, but with a little clean up, it'd be good to go. Water jet (I wish we had one at work) could have a great finish right off the bed.

Water cutting isn't to pricey either, my SS manifold flange was only 80bux to cut and was super smooth, no cleanup needed.

I know of someone who does waterjetting.I was actually heading over there to see about an exhaust flange,so I can ask tommorow for a price for the intake also.

Get the price for maybe 10 in aluminum!

Eadohcturbo

^didn't get a chance to price..was unaware they close at 4:30pm ?? so i'll try tommorow.
If you have just a flange - what about the injector bosses and fuel rail mounting?

Another plus I thought of with the water jetting is that it'll be as true as the material itself. The laser may deform the material some as it is cutting. I would probably still be wise to plane the flange once it is welded on either way.

Another advantage for the 1.8, our mounting gear is on the head.

You 1.6 guys will have to cut your oem intakes far enough back to include that jazz like Braineack did whefn he built his manifold.
