Many of us have done swaps. To change engines often requires that the stock deck torsion springs need to be removed for clearance. Trouble is that when you remove the springs, the remote deck release will work but there is no force to pop the deck free so it can be lifted up. In short you lose the remote deck release function.
I've tried to remedy this by using a door popper but there are few places to locate them and they don't exert enough force to pop the latch.
Anyone discover anything that works?

I have Rodney's deck lift on a LS4 Fiero. While the deck doesn't lift by itself it does lift off the latch when I hit the release button in the cab.

Joe: No doubt Rodney makes great stuff. Thanks for the tip but on my setup I can use only one lift strut on the passenger side.( and I do have one there) The SSIC combined with the large CAI setup (4" hose) for the supercharger that I have on the drivers side of the engine negates the use of one there. So you have an LS4 -nice! Always liked them in a Fiero but the complexity of that swap always scared me away from doing one.

I suppose just using the key would work , neither of my Fieros have poppers.

Could you install a regualr hood popper with spring like whats on the front hood?

I have no idea what you're talking about... I took out my torsion bars, and my power decklid works just fine.

I thought the design intent is:
The torsion rods reduce the effective weight of the decklid for easier opening.
The rubber trunk seal compression releases the catch when the solenoid releases the latch.

Do you have that heavy spoiler sitting on the rear of the deck lid?

In most cases the release latch on my 86 SE will not raise the decklid at all especially after a few weeks of being closed. I just went out and tried it with a willing observer watching the lid. It didn't move at all and I have the original torsion rods along with a pair of Rodney lifts.

However I can go back and lift it by hand. Sometimes the lid will stick to the seal but it still opens. It appears that the latch operates like an over-center mechanism and once it energized it stays in the release position until you close the lid.

Now that its been open a few times it will raise about an inch when hitting the release. Either way it still opens even if it appears closed. You may want to dig into the archives and find where someone put a Cadillac closer/opener on his Fiero. It raises the lid about an inch or so when you hit the release. When you close it just push the lid down until the latch engages and it will automatically pull it down tight.

I was thinking about doing it to mine but I have too many projects going on.

Yes, I have a stock spoiler.

-Mitch

Edit to add, sometimes when I take my decklid off my car, it doesn't work until I get the lid aligned perfectly.

I only use one lift cylinder on the builds that I do. I have completed 4 LS4 swaps and 3 of them use just the 1 lift cylinder. The other LS4 swap was in a Murcielago kit car.

Mine works just fine with the spoiler attached and no springs. The trunk gasket gives it just enough push to clear the latch when I hit the button.

3.4 DOHC swap is complete and running, now just have to finish the rest of the car...

I've seen one or more where someone made their own set up. They mounted the bottom of the strut much lower so it has lift all the time. There is no easy place to mount them lower so mine go on the shock tower so they are easy bolt on. But someone that wants to make some kind of bracket etc and mount it lower they can get the lid to raise all the way just by hitting the trunk release switch. Weld or drill into the shock tower wall or mount to the rear wall etc. The cruise system also gets in the way some etc.

Good info. Thanks for all the replies. I guess that it is possible to pop the latch with one strut. Back to the drawing board.

Can you raise the hood bumper stops things so when you close it there is some tension?

My 3800 sc car has Rodney's single strut on the passenger side with no torsion bars. It pops open every time, but it does have to be lifted part way up before staying up under strut pressure. I have a Camaro spoiler on it. Likely weighs about what a stock one would weigh.
