Identify Me. (Only kinda sorta Miata related)
 

Hey all.

Few months back I went crazy on Yahoo Japan and bought a set of ITB's for what was listed as BP-ZE for absolutely retarded cheap. When they arrived I compared them to a 1.6 manifold I had laying around. looked very similar but bigger... The port spacing was wider so hurrr duurrr I assumed(wrong) that it was 1.8L! I don't have a spare engine/head that is 1.8 so I couldn't at the time check it out.

Doing the turbo thing I made up a plentum for it, fabbed a custom fuel rail and basically made it in to a functional setup. I was going to install it in a few weeks so I grabbed new gaskets. Problemo.

See attached picture. I have made an error, full stop.

So to actually get my money out of this thing, I now need to know what the fuck it fits. If you even have a vague idea that can help me out that would be great.

In the running right now is a Lancia Delta Integrale or possibly a 4g63 non cyclone(the smaller ones?)

I am going to try and aquire some gaskets to help identify it and hopefully make my cash money back on them.

And yes they are dual injector for the keen eyes.

Damn man, sucks you went through the effort to build a plentum for them and they aren't the right flange. Live and learn. I have no clue what they are for.. there are so many motors they could fit. b18 possible? That is a wild guess but I could see through translation BP 1.8 and B18 getting confused.

this is what you get for going ITB.

I highly doubt it's a B18 as the B18 port spacing is close enough that you can cut off the flange of a B18 IM and weld on a Miata one.

Good point and excellent deductive logic.

I feel like it must be at least a 2L engine by the size of the port spacing.

To get things in perspective, is that a 1.6 or 1.8 gasket? Bolt spacing looks so close pattern-wise that I'd mistake it for a 1.8 flange on a 1.6 gasket.

That would be a 1.8L gasket on the mystery flange.

Gotcha. Then I'm out of suggestions :giggle:

Maybe i don't know how to ITB, but why not just build some adapter runners?

How hard could it be?

Is that the Techno Toy ITB adapter for Toyota ITB's?

Or something similar?

I have no idea. I've exhausted my CR knowledge.

It is a Japanese company called ARRAM, they make throttle bodies for OE stuff. It is dual injector and very odd. Very little info on the net.

Because it came up in another forum, port spacing is 100mm center to center.

Sucks that I fabbed up the rail and plentum and it won't work...

I'm amazed that someone would do all that beautiful work without even verifying what the heck it even is lolol

I mean seriously, do you just love to piss away big amounts of time and money? haha it really is pretty lookin though

True story. I'm crossing my fingers that OP lives near me and wants to make money on a side job or two.

Hey, I know it was bone headed! Just means I have to make another one at some point.

I am glad I didn't make it dual plane like I originally intended. That would have truly been a waste of time.

But seriously it looks the part and was labeled as ITBs for a BP! Other than it being to big it actually does look like a BP flange. And I didn't have a head or gasket to compare it to at the time other than a 1.6 intake.

I live in Canuckia on the West Coast and love doing odd fabrication.

Maybe its a Mitsubishi flange? IIRC their intake manifold flange has a similar bolt layout.

the 4g63 is way bigger openings and way wider......unless is some other mitsu you're talking about

vibrant should have flanges listed with the specs on them. cross your measurements with the popular flanges listed by them. hopefully you can get an answer. should be easier than ordering more incorrect gaskets.

nice job on the aluminum work BTW! hopefully once you learn what it fits you could break even and learn from the experience. it wasnt a waste if your learned something from this.

mazda F engine?

Standing by to cream myself if this is the correct answer. :dealwithit:

I was hoping you would know. Is the F engine intake flange just a bigger version of the B engine flange? And is the bore spacing 100ishmm?

I was just about to page you.

I've heard of people easily adapting BP manifolds to FE3s...

But i haven't heard the same with the F2T.

I can measure the bore shit on an F2T tomorrow, but i doubt anyone ever made ITBs for that motor for various reasons.

But its from Japan, they do things weirdly.

F2Ts weren't common in Japan. Bulk of them were sold in Australia and 'Murica.

Oh and I'm guessing the F2T use a different intake manifold flange as the FE3 and stuff based on how you're talking.

Correct. The F2T and FE3 share almost nothing besides bolt pattern.


I may or may not know how to strap an FE3 head to an F2T block, but that's besides the point. (The power numbers out of the combination would probably make the eyes bug out of your head, though.)


But now you know why i'm interested in creaming myself even if this is an FE3 unit, which i typically don't mess with. Well... that and i have access to a 2.2 FE3 stroker at the moment.

I looked at a few different F variants and some were pretty damn close :|

I am sure some adapter could be made as long as port spacing was close. The big issue with me machining up an adapter for the 1.8L is the port spacing is to wide and it would leave some not nice transitions :(

I have a buddy with an FE3, i'll see if he can measure it.

If it's for an FE3 or F2T, i'm calling dibs right now.

FE3 exhaust side is pretty damn close to BP... inner runners are about 2mm off. That doesn't really help us a whole lot just yet, though.

Here are actual dimensions +- 1mm.

I am thinking about adding a reward for a correct answer for what the hell this is for, Incentive if you will.
