Fiero2M8,

I've been watching your thread with interest. You are doing a heckuva job on that car from what I can tell

Was the lumina wing mounted to your decklid? How did it fit? That picture you have there looks really nice.

Also - how did you get enough volume to mount a 10 inch sub under the dash? I held mine up and it didn't seem like a nice fit at all. I guess I'm still not 100% of how I want to mount my 10 in my car

Thanks,
Andrew

Looking good! I'm curious to see how you get that strut tower brace to work. Steven and I played with one at a junkyard once and while it looks like it just fits, you can't close the decklid. I'd say you'd either have to cut and reweld the bar to sit lower to clear the decklid, or notch parts of the decklid to clear.




That one we found sure fit a lot better than his!
I think it was from a later Sunbird? May have even been a Sunfire..

I believe the stress bar I got was off a Buick 3800 or Cadillac 4.9, so I know it's too long but the center bar just unbolts and can be shortened.
If I use it at all, it would be after the motor is in, and I was hoping to flip it upside down to solve the clearance problem - I guess we'll see...

Hi Andrew,

Thanks, I glad you're interested. My build is definitely of the home/novice/budget type compared to many on PFF, but I'm having fun with my Fiero
Yes the Lumina Z34 spoiler (1992) fits easily by drilling 4 holes in the decklid - I did that on mine last year.
The tricky part is the center mount.
You can get the nut on but it is very close to the lock cylinder that you have to remove to do it.
The other problem is the keyhole is hard to access without mods to the center support.
I ended up removing the centre support completely, but it flexes a little without it.

Here are a few pics of it installed:









The 10" sub doesn't even fit unless the vent cables are relocated.
It is a fairly tight fit and is only using limited dash space as box volume (approx .7 cu.ft)
My sub box in the front compartment is just over 1 cubic foot.
Since my 4 - 4x10s are only powered by the deck, I was more concerned about too much bass with the amp I am using, so if it doesn't sound good I can always remove or relocate the sub under the dash and port the front box into the cabin.



Tonight I was working on modding some Grand Prix side skirts to cover the bottom of the X-frame.
I will post some pics of that this weekend.

Ahhh, the one we found was all welded. It would've required some cutting and welding to work. Hope this works out well for you, your project looks great so far!

Fiero2m8,

Thanks for the reply! I hate to be the guy asking questions about a mod you've uninstalled in favour of a new one I've seen the Camaro lip idea before - but never a Lumina Z34 wing. It looks really nice on there, as does the lip spoiler of course.

My car has the luggage rack on it at present, which is well, pretty gross I've been exploring the options to improve the looks. My first Fiero had a plain decklid, and I think that's a nice look too - the lip is very complementary to that.

On the subwoofer - is yours a free air sub?

Anyway, thanks again. You say that this is a "home/novice/budget" type of build, but I think you're being too modest of your skills. You've got some great stuff going on there that's well beyond this novice!

Cheers,
Andrew

Thanks Andrew.
I am keeping the Z34 wing I put on my luggage rack decklid.
It needs quite a bit of work but I may do a decklid build in the future with it.
I just decided I preferred a spoiler vs. a wing on a roadster, but I did get alot of compliments on the other one.

The under dash sub is sort of a soft box where I used a fiberglass underpad material to line the odd shape of the dash.
It should absorb unwanted noises but isn't an air tight design or a proper box.
I think an 8" sub in a tube would be better suited under the dash.
I've also seen a 10" in the passenger footwell area, but I didn't want mine to be seen.

Cheerio

A few pictures of the 1994 Pontiac Grand Prix skirts installed.
They are by no means finished at the wheelwells or blended in yet, but I sprayed them with black bumper paint to get an idea how they will look.
I used the harware clips to install them and screws underneath.
It makes the profile lower and wider, although it is starting to look like typical Pontiac bodyside cladding the designers were so addicted to in the 80's to add "excitement"

Ryan,

More updates!

Sorry for the delay Andrew.
No to worry though you didn't miss anything as I've been too busy at work to make much progress.
However I stopped by the Hot Rod shop today and snapped these pictures of the progress. Let me know what you guys think...

V-belt pulley installed for additional frame clearance


Heads are ported for larger valves and crane cam is installed


Piranha Pro nozzles and stainless tubing for Nitrous Express direct port kit


Block is .0065 inch over (365 cu in. / 6.0 Litre) with forged pistons installed and crank balanced.
Notice high flow oil pump


View from top showing tight plumbing so Corvette Fuel Rail covers can be adapted to fit over nozzles
