Forgot to add that RockAuto ended up having the best prices I could find for a new brake master cylinder and flex lines, so they are on the way.

Hey Russ, is this anything like what you started doing for your air intake?

Yes. that's exactly what I built as a base plate. however that's also as far as I ever got with the project. I did cut a hole in my decklid however  . my concept was to have a clear plexi "bubble" mounted to the baseplate, and that would stick through the decklid (an inch or so)as a "shaker" style intake. that way you show off the individual stacks, yet still have a good filter system. I haven't found anyone around here that can produce a bubble for me however.

Cool! I think there will be enough space below the deck lid for now. I can always cut a hole in the deck lid in the future if it seems like a good idea later.
While I wait for the brake parts and the 2 1/4 hole punch to arrive I will try to finish swapping out the power accessory parts and install the new dew-wipes in the 86 fiero.

Not too much to report. I took the window regulators out of the 86GT(yellow coupe body) and put new aftermarket motors on them. I took the donor car regulators (86GT early coupe style with 180K miles on it before parting out) and put new aftermarket motors on them. I put the donor car regulators in the 86GT(yellow coupe body) and also installed the new dew wipes. Other than the drivers side headlight gear needing replacement, the daily driver is almost in normal condition for driving.
I started working on installing the brake flex lines and master cylinder on the 88 but ran into some resistance trying to get the front right rotor off. 24 hours of PB, heat, hammering and pulling finely paid off and I was able to R&R that brake setup. I just need do the left front brakes and install the flex line for the left rear brake. The master cylinder will be last to go on.
Picture of a stubborn right front rotor. This was after approximately 22 hours of working on trying to pull it off the hub. Amazing what 21 years and some light rust can do.

Holy crap, this build is looking pretty damn sharp. The fabrication work is impeccable! Bring on more updates! [This message has been edited by Carcenomy (edited 05-11-2009).]

I will go with a 4 or 5 inch diameter filter or bigger if possible. If not then try using 2 of 3" diameter filters one on each side... You have upgraded the air flow from the factory Single throttle body, and this clearly is a step forward. Now don’t take a step back and get a 3" restricted filter in there...

I am not familiar with the cold air systems or what should be considered minimums. Can you tell me if it is important to just have a larger filter opening (using an adapter to neck down the size from 5" to 3" tubing) or do I need a 4 or 5 inch intake tube in addition to the larger filter? I assume that in this case larger is better but with the limited room larger tubing means exponentially increasing the difficulty in routing and fitment.
Thank you for your input!

In an ideal scenario, would be not having any kind of restrictions at all. Take a look at some race cars intakes.
Of course these are the extreme applications were HP is the ultimate goal at the expense of the engine’s life spam (That’s what sponsor’s are for…). But for a street application there is the need to keep debrief from flying into the engine for obvious reasons. However keeping the restrictions to a minimal is the key factor, so the least amount of HP is sacrificed. You have already overcome the biggest of all challenges by using an ITB setup. Making the best use of it includes to provide Little to None restrictions.
Because the location of the engine of the Fiero (behind the rear windshield). You do have to induce air flow with the use of an air scoop to help the airflow. Now to keep things clean I would try to get a set of Mini K&N filters for each TB.
http://www.epicwelding.com/...images/honda_itb.jpg
But if the use of a box is what you have in mind try to make the thing as BIG as possible, and do make sure the air filters that you use are big in diameter. When I was talking of 4 to 5 inches I was talking of the Air filter’s diameter (at the neck), where the air filter meets the intake tube.
I can’t remember the exact size of the stock N* TB, but I think it is like 75mm and that is roughly 3 inches in diameter. And I don’t know for sure the diameter of each of your TB but if I had to guess it is about 44mm each that is almost 2 inches “Each” and you have 8 of them... Means that if you had to put together all of your ITBs areas into a single TB you would have to have a TB that was at least 11 or bigger Throttle body. So can’t really expect to match it to a 3 inch Air filter.
If you care for the exact size you can do the math A(cir)= (pi) x (r)square

Doing the math using 8 - 40mm throttle bodies, I come up with an equivalent single tube size of 4.4548". I don't know if I can run tubing that large or not but I will check into it. Thanks again for the input.
