Most people will probably tell you that the 3.4 upper isn't worth the trouble, but that's relative to the installation of the 3.4 in the Fiero.
OTOH, if you're going to a DIS 3.1, it may very well be a different story.
Although it's kind of marginal for a modded 3.4, it ought to flow plenty for a 3.1.
And it looks really cool.
The Fiero upper has a huge restriction where the neck joins the main part of the plenum. The opening is even smaller than an un-bored Fiero TB.

As you mentioned, the thermostat housing is in the way, but someone on the Forum cut a "C" notch out of the end runner, and welded it up.
Looked like it should work really well.

While we're on the 3.1...
The FWD Lumina car has aluminum heads with much smaller chambers. It has lower compression pistons to accommodate.
You'll need the pistons for the iron head version. Think CamaroBird or 91 Lumina minivan (also with iron heads.)

Edit - Since you're already swapping ECMs and using DIS, just swap in the Lumina engine in its entirety. Its intake and heads flow much better than the Fiero's. You might be able to reuse the Fiero timing cover and accessory brackets to save yourself a bit of re-engineering. You might lose one bolt hole on the heads, though.

If you can get www.60degreev6.com/index to load, there's a wealth of information about these engines.
(You may have to hit "refresh" to get pages to load. It's kind of cranky.)




Thanks for the comments.

I was hoping the stock 3.4 upper flowed better than the 2.8 upper. Now it's just the matter of finding one in a local boneyard. While I'm there I'll be loooking for a 7730 ECU and a neutrally balanced flywheel, although I expect to have to buy a new flywheel.

Since I'd already purchased complete new 2.8 valvetrain components and started porting the iron heads before deciding to go with the 3.1, I'm pretty much committed to using the 2.8 iron heads. The correct pistons an iron head 3.1 were delivered from Rock Auto via FedEx today.

Just a bump to keep the thread alive.

I've had to free up the garage for my daughter's use during the winter, so about a month and a half ago I reinstalled the cradle, suspension and brakes and just pushed the car out to the side of the driveway for winter (under a all season cover).

The engine block's back from the machine shop, crank and pistons have been installed. It's been oiled up and bagged until things warm up a bit. (it's been -20 or below for the last week and a half )

I've just about finished porting (well, mostly just gasket matching) the lower and middle intake manifolds. Since I have a few days off over the holidays, I'll post up a few pictures of the finished pieces.

Cheers

Nice car. Like what you are doing with it. I pretty much just finished mine recently. Stroked her out to 3.1. I went with a new block, along with all high end internals, new heads, .388 cam, matched all the runners, hogged out manifolds (easy process, and good for about 15 hp), 1.6 rollers, and all new accessories. Also did my suspension with all new everything. Painted and detailed frame and undercarriage. Now she will not blow the doors off of a Vette, but she handles and performs with the best cars out there. Slotted and drilled rotors, braided lines, and poly throughout. I also went with Eibach springs and KYB shocks and struts. I am looking forward to spring to do a little SCCA cone racing myself. Trully enjoy what you are putting together. Out of all my handeling features that I added to her, my hands down favorite item is a rear stabilizer bar. Read in an earlier post of yours that that was one of your plans. FYI, it is a valuable piece. Until the snow, I have been driving her on our nearby mountains, and she is just a dream. Good luck with your build, and enjoy the time spent with your son. You my sir, are a good father. Great story. Just picked up on it today. Keep it alive.

I guess this is an "I haven't done any work, but the parts have been coming in" bump.

Plans have changed a bit over the winter, and I've been accumulating some parts to proceed with turbocharging the 3.1

Yesterday the FedEx truck came by and dropped off an interesting box

Here's the T3/T04E turbo, specs are 50 trim .5A/R T04E compressor and stage 3 T3 turbine with a .63 A/R housing :


A shot of the turbine exit

And another looking through the 3" v-band "Ultimate wastegate"


So the plan is to use this Sy/Ty W2A intercooler



and this dual 48mm LT1 throttle body (same one as used on the Sy/Ty)


Finally most of the big ticket items have arrived.

Still need to finish the design parameters of the sheet metal intake that will be needed for the throttle body, and fab up both it and the exhaust system. Then, of course, it's being nickeled and dimed to death with oil and water fittings, hoses, clamps, W/G actuator, W/G solenoid, BOV.......

Cheers

I like your project and my mom has a 93 Ty so them parts look familiar

Is that an AIr/Water intercooler? This is exactly what I want to do to mine over the next year, so I'm watching with interest!
TiredGXP MAY 29, 12:40 AM
Yes, it's a water to air intercooler - picked up used on eBay.

Progress is going to be slow - I'm swamped at work for the next two months.

Looks like we'll also be moving into a new house in July, so lots of work to get our current place ready to sell and then all the landscaping that the new place will require. At least the new place will have an insulated garage, so there should be enough heat to work on it into the winter - my best guess is that this will be on the road next spring.

So I see it's been over eight years since I last posted here, and really also that long since I last worked on the car. That's about to be remedied.

The wife and I are both retired now, and we're in the process of moving to Vancouver Island, the car and all the accumulated parts have been loaded into a shipping container with the rest of the shop equipment. The new place has a good sized, heated shop, so once some home redecoration/renovation projects are done, I'll have lots of time to work on the car. I'm looking forward to it.

That looks slow yet fun project. My uncle used to have an SE 2M6, just nice to a project here.
