Fiero 2m8 LT1 NX Roadster conversion (Page 28/46)

I was having a hard time starting the car when it was hot and I hadn't done anything different to the car to cause that problem.
After some research on www.CamaroZ28.com and concluded that my ICM (Ignition control module) was acting up when it got hot.
However, I did a few check first before buying the part.
Since Fiero engine bays are warm, I had previously relocated it to a cooler spot.
Some posts recommend heating the old one with a hair dryer to see if it causes a no or hard start.
The Fuel pressure was good cranking hot.
I didn't think it was flooded because it wouldn't start with the pedal to the floor.
I ruled out vapour lock because the fuel lines and fuel filter hadn't move moved in 2 years.
Also, I was hoping the new Distributor might have solved it but it did it with both Optispark distributors so I could rule that out.
So I broke down and ordered a new one from GM, bolted it to my MSD coil and remounted it.
Presto, problem solved.
Nice when the first part you buy solves the problem!


On the topic of starting, I decided to try a new Optima battery in the engine bay with short thick 1 Guage cables to make life easier on my Powermaster 9004 starter.
I had previously went through two starter solenoids, so I thought moving the battery from the front might help.
Here are some pictures of it installed as a trial to see if I prefer it.
So far, it seems to work better.

Optima Red Top:




I mounted and bagged it on the left side of the engine compartment - these batteries are spill proof and can mount at any angle:




I will update everyone after some more mileage with my review of this mod:




Time to go for a cruise and enjoy the amazing weather this long weekend.

I picked up some new header collector gaskets and installed them:




When using aluminum "permanent" gaskets, make sure you use metal locknuts or double nut them like I did here:




Also picked up some new NGK TR6 spark plugs:




Next items to fix:

* shorter Nitrous line from bottle to solenoid
* re-jet to a 100HP shot and leaner setting once colder spark plugs installed
* ordered new flexplate that will need balancing and installation
* need to replace cracked axle boot on passenger side of trans
* speedo stopped working on the weekend

Always seems to be a WIP - good thing it's a hobby

I hope you have better luck with those aluminum ones than I did. Melted 2 sets with each lasting about 1000 miles. I now run Copper... But mine were on Stainless steel manifolds and hold in more heat than a traditional header, so that could have been my issue

Can you give me more details on the copper?
Manufacturer, pics, where to buy etc.
Good reference for if/when mine melt.

Here is the summit brand. They come in various sizes and there are other brands/vendors.

My new Flexplate came in yesterday for an 86 2.5L auto Fiero.
Parts Source said they were no longer available (only the V6 one was) but Canadian Tire got me a 4cyl one for $40CDN.
I brought it and the orginal LT1 Flexplate to Northtown Machine.
The plan is to have the new flexplate balanced to match the stock LT1 flexplate.
Here is the LT1 flexplate (notice the weight is in line with the guide pin hole:




The new Fiero 4cyl flexplate has no weight on it and has 6 symmetrical holes:




So the question from the machine shop was, where is my reference point on the new one (since I didn't bring Archie's adapter in)

I called Archie and he answered the phone and was very helpful - especially since I confused him by accidentally agreeing that I had a V6 plate and they are DIFFERENT.

Anyways after walking over and looking at an adapter, he confirmed that my reference point would be on the center line of any of the six holes on the new Fiero 4 cylinder flexplate.

I should have it back and balanced next week - now I'm looking for tips on the easiest way to complete the flexplate swap....

Not much to report as it's busy at work this time of year.
I picked up the balanced flexplate last week, here it is...




Also the speedo stopped working, so I have to investigate the wiring from the VSS.

Doing some research for winter projects in addition to the flexplate install.
I have added rear coilovers, front poly bushings, and lowering front springs to the list.
(Not to mention finishing the bodywork )

This past weekend I was visiting my brother's new place in Troy, Michigan as he transferred to GM's headquarters in Detroit.
Any Pennock's people in the area?

Starting to collect my parts for the winter Fiero2m8 projects.
Today I picked up the Prothane complete kit for the 84-87 Fiero.
It contains everything I need except the engine cradle (K-frame) mounts that I already installed last year.



Cheers,
Ryan

Well here's the latest on the bodywork...
I just picked up a GT aero nose to match the rear bumper cover I installed in the summer.
Good thing I hadn't finished the bodywork yet
Actually, I will have to redo the front flares, but no sense finishing the bodywork before I'm totally happy with the looks.
Here's a couple shots of the new piece:




I will show shots of it installed soon:




If only I could find a better spot for the front license plate...

Well, today I got the bumper pad nose exchanged for the aero nose.
I am pleased with the results - it matches the rear now.
It's not hard to swap a nose cone, just took my time and enjoyed the process.

Here are the pictures - if anyone has questions, let me know.

First all the top, side and bottom fasteners were removed and the driving lights were disconnected:




I removed the emblem (not sure if it's going on the new one yet) and I had to separate the flares from the bumper before it came off:
Yeah, there's surface rust cause this car wasn't garaged and was winter driven despite only 35K miles on it. (still not bad for over 20 years old in Canada...)




Here's the old one removed with the Daytona Turbo Z skirt still attached:




The 5mph waffle plastic was transferred into the new front end - it fit the same as the other one and I held it in place temporarily with masking tape:




Here you can see I'm gonna have to cut and reshape the flares like I did with the rear ones:




I spent the most time realigning the hood to bumper gap using the adjustment nuts on the hood hinges:




You'd probably noticed the front license plate holder is gone too - still brainstorming what to do about it:




I didn't have to touch the indicator lights, although I've been thinking I might install flush mount ones front and rear in the future:




I don't plan on reinstalling the front or rear side marker lights either, should make finishing the flares easier and better looking...although I'll probably install flush mounted aftermarket ones if the police notice they're gone:




The original owner isn't gonna recognize this car by the spring




Yeah, that's snow, our first of the season - that's why the seats covers went back on




Someone's gonna own Page 8 soon
