Just wondering if anyone still wants one of our intake manifolds or a set of headers. I'm not sure if I'm healthy enough to go into full production but whereas I have lots of CNC parts leftover I can build a few more.

Francis,

I have one intake and may be interested in acquiring a second one. PM me your anticipated pricing if you decide to assemble a few more intakes.

Nelson

I will post the pricing after I make one.

glad to hear you are feeling better...would like to price an intake

Not sure yet on the pricing yet as I may make changes to them. What with my son's racing success and his other projects, he doesn't want to make any more products for the fieros; profit margin is way too low, shop space is limited and he don't want me working anymore for health reasons. Thus, it will be a while, whereas I have a lot special tools, jigs, machines, materiel and whatnot to move from our shop -trueleo racing- to my shop.

I'm happy that you're feeling better. Or at least feeling well enough to think about working again. That's always a good sign.
At some point, I'd like to try swapping in a 3.5 or 3.9 (same block and heads) from a G6 into a Fiero. I wouldn't mind installing a good set of headers instead of the iron manifolds, if they were available.
I'm sure the ports are different from the 2.8. I'm not sure in what way, however.
It would be cool if the port spacing and the flange surfaces were similar. Having said all that, I don't have any way to compare/measure them. At least not right now.

Just go buy yourself set exhaust manifold gaskets and compare them.

Hey Francis, it's good to hear you're feeling better.

Also, I'd be happy to buy another set of headers.

I'm in for another set of headers.

I recommend a ceramic coating option as well...

I would be interested in a new intake for my turbo re-build. I hope you have a speedy recovery.

To keep cost down - and make installation easier- I've been thinking about a new header design. They will not be equal length, thought still retain the big runners and big Y pipes etc and good collector input angles. As for performance lost, there should be very little difference compared to our equal length headers. So what ya think?

I think any headers are better than no headers.
You might also want to look at the headers that are available from Summit for the F-body 3.4 ... Perhaps those could be cut and re-welded to work...

Interesting...they look better than Sprint, but not sure how they will clear everything -clutch slave, and whatnot- on a Fiero?

I'd keep them at least 22". Glad to see you're well enough to get ambitious.

Same here.

I think the one intake I already have from you, Francis T, is a custom design of yours. It's possibly a limited-production or one-off design because its plenum is not shaped like a cylinder, but more like an asymmetrical bottle of Stabil fuel stabilizer with one long neck emanating from the right front of the plenum.

However, the second one I may be interested is a different custom design of yours which Raydar computerized for you for use on your now-archived 2011 thread, titled, "need feedback on a new intake designe"
( https://www.fiero.nl/forum/A...130314-1-085806.html ).

Your intake manifold design in the drawing you first came up with presumably looks something like this, but without the jagged edges evidenced by the computerized translation of your drawing:


I'm hoping you can make the aluminum panel atop the plenum both thick and non-porous enough for me to get it successfully chrome-plated locally, just as was done with my Fiero's otherwise stock, aluminum valve covers. Then, to match the look of my Fiero's valve covers, I could set off the fins you mentioned would be atop your new intake manifold, with some heat-resistant black tape just as I did my Fiero's chromed valve covers' fins.

This is basically yours; and while I liked it a lot, it took a lot more work. Sorry but that one was a real %**% pain to make, and thus I doubt if I will make another.

BTW: over the years we've had request to make dual TB manifolds. What with the flow bench numbers showing a single TB good for around 300HP we never went that route.
I think I can use the Dual TB approach to achieve another goal, keeping cost down. Yeah it sounds nuts, but by doing such I think i maybe make them easier to build. What are your thoughts people, anyone interested in a twin TB?

Yes, I agree. The manifold depicted in the photobucket links you've provided above looks much like mine, but mine from you has a noticeably smoother neck, so the welds in the neck area are virtually invisible.

Yes, I'd be interested in a dual-plenum intake manifold, possibly something similar to the one-off dual-plenum set-up pictured below:

However, regardless of the number of throttle bodies, I prefer to continue to use my CAI (cold air induction) system, which is largely based on the built-in OEM CAI system of a Fiero, --- both of which draw in cooler air from outside the engine compartment, rather than drawing in hotter air from inside the engine compartment. Given your racing experience, I know you're aware of the benefits of doing that.

Love the look of the twin TB........

Headers are a must.
For intakes, the DAWG-mod with a 57mm TB addresses 98% of the flow needs of most people...and you can get that done by any machine shop for under $200

Sorry people, but my family killed my plans. My son Troy flatly refuses to move the equipment to my shop as he don't want me doing any metal fabricating with the blood thinners I'm on. My wife and RN daughter agree quite strongly. Whereas I doubt if I ever shipped and intake or header set that I didn't get cut at least once building; I suppose they have a point. Last week they replaced my ICD and it took 4 days instead 1 for the bleeding to stop. Thus I'm going to need to find a new safer hobby. Maybe a mistress, naw...

Anyway all is not lost, Troy did agree to let me sell our components including all the CNCed steel flanges needed to make our hi-flow intakes;a first.
For those that can weld or have friend that can, I'll put together and take photos of all parts, make draft a drawing on how to build a dual TB intake as they will be easier than a single plenum and look meaner. Like I said earlier, sorry people.

Health always comes first.

Well, I think I have solution that the family and I can agree on. I've been working on plans for a Dual Plenum/Twin TBs intake kit. And it really looks doable for the average mechanic providing he can weld or can take it to someone that can. I will make one for my 87GT first to confirm everything.
I'll post some drawings soon. I'm not sure if there will be much interest in DIY intake manifold kits?

I'm sure there will be some.

You've piqued my interest

My M.S.Word is mot working as before, wheres I can't get the select arrow to group objects. If someone here cares to see if they can fix the file or whatever on their system, I'll send it.
Which will let me complete the drawing and post it here.
Thanks

I would be strongly interested in one similar that is pictured in this thread!

Well, I got feed up with M.S.Word's drawing ap and ordered CAD software.

P.M. sent.

I have an M.S.Word file with most of the basic design features. It's not proportioned as it should be; something I'll fix when my CAD software gets here. Can someone here advise me as to what file format I can save an M.S.Word that can be displayed here? I tried .docx and .PDF The thing is both only show my text?

Also, the plan is to put together enough parts for 10-12 DTB and make 2 prototype - both are spoken-for, sorry.

Hmm what call them?
DTB Intake - Dual Throttle Bodies
DPM - Dual Plenum Manifold

More of these please!

Sorry, as of now, I can't; but you can get set of sprints. The runners are not equal and they enter the collects at poor angles, the Y pipe is one size -too small- throughout, but they're still better than stock. If I still have the jigs and whatnot I may offer a better Y designed to fit the Sprints.

I believe the Fiero Store's Y pipe doesn't have the D-crimp restriction, though Y pipes with a larger collector would be better. If anything, try to make longer arms that equalizes the length the exhaust travels on both sides before joining up.
