Glad to hear your still going on this project. That has to be the coolest exhaust system ever put into a Fiero, cant wait to hear this thing rumble!

Yup, still at it. Definitely a work in progress, but it should be all worth it in the end.

You read my mind actually. I think that type of bracing would be ideal for this Fiero... if I can find a good way to work around the firewall header and deck lid hinge mounts, I would like to add support tubes from the strut tower brace I made... much like the Fox body Mustang brace.

There isn't really much structure in the middle of the firewall.
It might help to build an X-brace to connect the strut towers and hinge boxes, but what would help the most would be an X connecting each strut tower to the joint between the firewall and upper frame rail on the opposite side.

And of course a lateral member to connect the strut towers since the stock one is gone.

The cross-bracing will be a challenge because of the height. You are right about the firewall strength, there isn't much for structure for sufficient brace support. I also agree that the top frame rails meeting the firewall would be the ideal place to brace. Not sure yet the best way to go yet, I may have to get a little creative.

Update...

The TPI intake system is now sold and is on its way to what appears to be a perfect new home. For those Fiero owners who haven't seen the GMC Indy Hauler build thread, you really need to check it out:

http://www.fiero.nl/forum/Forum2/HTML/068185.html

The new Edelbrock AVS carburetor was also sold to a private party off craigslist.

Also sold my OEM tail light assemblies... new owner is already fixing them up (more on what's replacing them later):

I'm now looking to purchase a stand-alone fuel injection system to top off the new Performer RPM intake. I'm pretty excited about the move to this kind of EFI, should be well worth the investment. Looks like FiTech has some competition now... Holley just came out with their own EFI system called the Sniper, and it looks very promising (better looking too):

https://www.holley.com/prod...i_kits/parts/550-511

That said, FiTech just raised the bar at SEMA with their "Go Port EFI" system. If I was to go this route, it would be more money and I'd have to lose my new Edelbrock RPM intake... but the bottom line is that this type of direct-port injection would be the ideal setup to use with the 180 headers. It is (for now) just something I am considering:

http://fitechefi.com/default.asp.pg-GoPortEFI

I'm sure I'd be extremely pleased going with either route, so we'll se what the budget allows for. Also still contemplating what type of air filter setup to use...

On a side note, wow that TPI intake system was heavy. Total shipping weight (minus HEI distributor) was right at 50lbs! Definitely shedding some more weight by switching intake configurations.

I ran into a small delay with the headers, specifically with the top two primary tubes on the firewall side. They are too close together in one spot and hit as soon as they are compressed. As-is, the collector can barely be slid onto the tubes because of the interference. It appears the top tube wasn't quite bent right.

I called Schoenfeld to ask them about it, and in a nutshell I was told, "We have been making that header in the same jig for over 20 years and never heard of a problem."

So that was that. Looks like I will just have to make a trip to the muffler shop to get things tweaked before I go any further. A little frustrating, but not that big of a deal. I hope to have the problem fixed by next weekend so I can continue fitting the collectors and moving on to other things.

As always, stay "tuned."

Brett, thanks for props on the "Hauler", I do think the TPI will be a perfect addition, since the truck has a 4L60e trans the plans are to set it up obd2 using the 0411 pcm , for details see here.

Looking forward to seeing how your project comes along.

No problem, I really like your build and will visit it often... its such a unique idea! Kudos to you.

The way I look at it, the TPI intake is not only period-correct for your truck... but when its done, you can also proudly say that it came directly off of a V8 Archie-swapped Fiero...

How cool is that?
