Pretty big quote just to ask that question.
No. The stock sunroof - just painted on the topside to body color.

About the FI system. Easier said than done.
Not a lot of room for individual injectors etc. otherwise Pontiac would have done it.
As it is, NO Duke has anything other than carb or TBI.

FAST system's ECM just flooded my engine.
The conclusion was I had a case of "there's nothing wrong - but it just won't work right".
Whole story here: http://www.cpgnation.com/fo...day-not-today.22587/

It's running decent enough with the 7165 ECM - just a real bad bog when you punch it WOT that I can't get rid off.
Plus I have a knock sensor, ignition control etc. that the FAST did not have (fuel control only).
I think I'll need to use a turtle to reduce some of the volume in that huge open plenum.

(edit: oops - 1991 Jeeps had port injection Dukes - can't find any details though)

I am going efi and multi port..
there is tons of room.. Pontiac/g.m. didn't because of cost.. and it wasn't needed on a stock duke.. low rpm. good mpg. and didn't need to get every ounce of power and m.p.g. out of it, at that time, besides the olds quad made it pointless for them to invest anymore money in the duke..
anyways good, luck..
for now my indy will have a o.e.m. 2.5 built up some until I can afford a s/d and I'd really like to have the alum block that takes the chevy motorsports smallblock 2.2. head.

as far as the fast efi flooding your engine, it's because the injectors are to big.. for the air flow velocity in that intake/head ports.. at the rpm you'll be running most of the time.. should be interesting if the oem hacked ecu can control that tbi t/b better. or if the same problem will be there, to much fuel parking itself on the intake floor..

I look forward to seeing that in your build thread.

There was a beautiful setup on eBay some time back. He wanted big money but wouldn't include the "small bits".
And I wasn't sure if it would fit the engine bay or what I could use to control it at the time.

I had mentioned these WebElectric products earlier in the buildup.
I thought I'd post the website and GIFs of what they do.

http://www.webelectricproducts.com/products.htm

I installed their sequential turn signals module to get this.


I also have their brake pulser module for the LED 3rd brake light I installed in the wing.

The transmission in the Indy is getting harder to shift, sometimes almost impossible.

I've checked the shifter mechanism itself for broken welds/cracks. Everything's OK.
The cables are new Dickman units. I disconnected them from trans. The shifter/cables work freely.
I tried shifting the transmission manually. It's notchy and binding somewhat. Won't go into 1st at times.
I suppose there's an internal wear problem on the forks or something IN the transmission.

I have a NOS 1992 FWD Getrag 5-speed to install.
Just ordered the parts I need from Rodney.
This trans: http://www.fiero.nl/forum/Forum9/HTML/000038.html

I also ordered the same Bully clutch I have in my GT. I'm tired of that 'heavy" effort Spec clutch I have in there...
Because of the Bully pressure plate redesign, the pedal effort is light while still giving great clamping force.

EDIT: cradle taken out May 21

Things are starting to come together.

I had issues with shifting the old Getrag. We split the case and all the gears and differential looked OK.
The problem must be with worn shift forks or something else (synchros replaced not long ago).

Below is a NOS FWD Getrag 5-speed I picked up last year.
I had the Fiero's Getrag bellhousing half of the case swapped over.

The only part I needed from Rodney was the shifter mechanism for the shift shaft.

As I keep telling the guys DETAILING starts BEFORE you put it all together.

Of course, now is also a good time to refresh the cosmetics of the engine too.
I needed to replace a leaking rear main seal. Did the oil pan gasket at the same time.
Dirt and grime was washed off and the engine block spray-bombed Gloss Black.

You have to do the engine bay and cradle too! It's the easiest time to do all this.
(axles will be cleaned up once transmission is back on cradle)
I'm amazed how many people skip this step - too excited about doing their engine swap I guess.

I got my flywheel back from resurfacing and assembly balancing.

The flywheel HAD been zero balanced before, so I was surprised to see it needed anything at all.
The clutch is brand new, but even it needed a tweak to bring it into neutral balance.
This thing should be glass smooth to 8000 rpm!



The rear main seal had a slight leak and needed to be changed.
Easiest way to get it out is to drill 2 small holes in the seal and screw in 2 metal screws.
You can then pull it out with a claw hammer.

The cradle is ready to go back in!
When I did my auto-to-manual transmission swap, I forgot to take pics...
