If you mounted the coil on an aluminum bracket you may toast it because of a missing ground . You should run a ground wire from the coil to any steel part of the car, maybe a mounting screw of your bracket.

Hey Blacktree, who made your headers for you? I bought an '88 in March with headers that look almost identical with yours. The only problem is the guy before me had put header wrap on them and it ruined the headers. It kept so much heat in, it blew a hole about 2 1/4" out of the elbow on the #3 tube. I got it off and took it to the exhaust shop and the guy told me that the wrap changes the molecular structure of the metal, and may not hold a new weld. Anyway, I only got to drive the car another couple of weeks till I spun a main bearing, so at least it held that long. I am going to do a swap, but for now may just put in a 3.4. I would like headers to go back on it and would like to change them while the motor is out. I noticed you had put header wrap on yours too, so I hope you don't run into the same problem that I did. I was told,(and know from experience), that ceramic coating works and looks great. I used it on one of my Grand Nationals. BTW, are you going to the B.O.P. show next month at Old Town? Would like to see freak close-up.

To falcon_ca: Aluminum conducts electricity.
To Turbowedge: My headers were made by the Trueleo guys. Mine seem to be holding up pretty well so far. BTW, what's the date for the BOP show?
BTW, I did my baseline dyno run today. As I expected, the numbers were higher than the last dyno run. But I didn't expect the difference to be so noticeable. Here's the breakdown:
Last Year (with TH125 and stock ECM): 123 HP / 161 ft-lb
Today (with Getrag and 7730 ECM): 138 HP / 179 ft-lb
I also started the intake swap. I have to do some custom fabrication work to install the new intake. So it may take a couple days.[This message has been edited by Blacktree (edited 09-18-2008).]

But when I stepped back and looked at the car with the door trim removed, it looked MUCH better. That made up my mind. I'm going to shave all the side moldings.

I have 84 door panels on my car so thay are not the same could you take a pic of it and PM it to me I would like to see the differance too with the trim off.[This message has been edited by 85SEnochie (edited 09-19-2008).]

Blacktree, the show isOctober 25, 8-4 at Old Town. For more info go to oldsclubofflorida.com. How can I get a hold of Torelo? Thanks.

Blacktree : Yes, aluminum do conduct electricity, but only at a level of 62% in the best case (compare to copper or steel). It depends on the alloy used.
I would not take a chance.------------------

Here's a progress report on the custom intake. It's installed, but the charcoal canister still isn't hooked up. The parts for that should arrive in a few days. But nevertheless, it's going on the dyno tomorrow.
Since I'm using a throttle body from another car, I had to make some modifications to make it fit. Since it has a larger opening than the stock throttle body, the stock intake hose won't fit. I decided to use 3" ID flexible duct hose. Unfortunately, the hose connection on the air cleaner canister is an oddball size (3.25" OD). So the 3" ID hose won't fit. To fix this problem, I sliced up the flange on the air cleaner box, and bent it inwards to fit a piece of 3" OD exhaust pipe. The short piece of exhaust pipe will be my new hose flange. See photo below.
The next photo shows what it looked like after welding, grinding, and a fresh coat of paint.
The sheet metal in the air cleaner canister was so thin that my welder, even at the lowest power setting, was melting holes in it. So instead of making a continuous weld all the way around, I made several tack welds and filled in the rest with JB Weld.
The next task was to make the Fiero throttle cable work with the GN throttle body. The Fiero and GN throttle valves rotate in opposite directions. Plus, the bellcranks are different. So I had to modify the throttle cable mounting bracket. Below are a couple shots of the bracket before modification.
If you look closely, you'll see 3 cable attachment points, for the throttle, TV cable (auto trans only), and cruise control. Since my Fiero doesn't have cruise control or an automatic transmission, I'm only concerned about the throttle cable.
In the photos above, the throttle cable attachment point is the one hanging down on the bottom. I had to flip it upside-down, so it was sticking up. And I also had to move it away from the throttle body a bit. The photos below show the modified bracket.
Also, the GN throttle body has a vacuum distribution block built into it. So instead of connecting vacuum lines all over the intake manifold, I re-routed them to the vacuum distribution block underneath the throttle body. This helps to clean up the appearance of the engine bay. Speaking of cleaning, I need to clean the engine. All the grime that the stock intake was hiding is now visible. But here's a quick shot, just to give you an idea how everything fits together.
Tomorrow, we'll get to see some dyno charts!  [This message has been edited by Blacktree (edited 10-02-2017).]

OK, the dyno results are in. And I think they're going to make some people a little unhappy. In the chart below, the red is the stock (ported) intake manifold and stock throttle body. The blue is the Trueleo intake and GN throttle body.
The new intake setup seems to have flattened the torque curve a little. And it appears to have shifted the peak HP upwards a few hundred RPM. But the difference is really minor. All I can say is that I'm underwhelmed.[This message has been edited by Blacktree (edited 10-02-2017).]
