I'm wondering about using door poppers to remotely open lambo doors. I know you can pop the doors out but has anyone ever set up the pistons to lift the door by themselves?
I would think that if that was done then it would be too hard to pull them back down to close. I've been thinking that remote door openers would be soooo cool. I've seen the power opperated lambo doors. They're nice but they cost over $1000 so I'm not too keen on that idea.

I looked into this a year or two ago, the doors would be two hard to pull down if the struts were strong enough to raise them without help. Trust me from a sitting position pulling the doors down can be a job if the door weight and struts are not balanced just right. Then you have to worry about clearing the door stop before the door raises and for that a popper is not that accurate and would have pop the door open by several inches. Then if you go total automatic open and close, you have to take safety into consideration ex: total loss of power in an accident will the door open? You would have to develop some type of quick release and hope it works.
Just remember that a stock fiero door is pretty heavy.(65 lbs? 85lbs? I forget)
Just make sure whatever system you find can handle more then that weight. (and also take note to the temp range of the system - make sure it can run ok in your local climate)

True my doors go up easy in the summer and are hard to pulldown and in the winter the reverse.

That is how my murci replica is set up. I'm not sure of the weight, but they are balanced by the strut so that they don't fly up and are easy to pull down. I don't think that weight is an issue if you have the right struts. We're looking at an rfid system as part of my LS4 swap. With that I can go keyless. The car will recognize me and open the door when I approach. Then all I have to do is put my foot on the brake and push a button to start the car.

I have had two Dodge mini vans (don't hate me) that have had the auto open rear hatch. That rear hatch has to be as heavy as a Fiero door. I have been looking for a system at the local junkyard but have not found one yet. I do plan on pulling one someday and making it work. If it can't do the door, then maybe the trunk or hood. They even have the "auto pull" close feature. The one that you just click the door and it auto pulls it shut, so you don't have to "slam" anything anymore.

All you need is a pair of linear actuators in parallel with the gas strut to drive it up and down. The ricers have had auto opening trunks for some time now. It doesn't have to be fully automated like you push a button to pop it open and drive it up and all that. Just a motor and a reversing switch. They are about $100 and change apiece.

I've been looking into this as well for my Countach build. Walk up to the car, and the doors unlock, get in push start, leave the car, the doors auto lock. How cool would that be?! I have seen a couple of systems become available in the last couple years.
Lambo, What I don't like about that one is the thick "credit card" You have to carry in your wallet. I've been researching them and they run all the way from $68 to $450. Most (all)of them come from china, and a lot of them don't accept paypal. It's a risk to send a money order or western union to someone on the other side of the world and hope that it comes out ok. I'm still trying to decide whether or not to take that gamble. I also think that if we wait, that there will be better cheaper options out there. Incidentally the cheapest one I've found actually has the toyota name and symbol on it.
The problem with a lot of vertical door kits is that the door has to swing slightly outwards from the car like normal and then upwards. When I had vertical door hinges on my Eclipse Spyder this is the method of how they opened, and I tried everything I could to reduce that action including using higher weight rated struts and adjusting the swing to be as minimal as possible. Unfortunately, I never completely removed that 'swing open horizontal' action at all. And that will be what will keep you from completely customizing most vertical door hinge kits to open automatically.
It works so well on that Lambo because all the doors have to do is open straight up. There's also a DeLorean on YouTube that has automatic door poppers and since those doors also open straight up there is no problem.
That being said though, I guess anything is possible if you're willing to spend the dough on it...
Right Freak, duh, I totally forgot how those doors work and you're right. Mine has a lot less to deal with. In my defense I had my first stroke yesterday so I could have been a lot stupider. As strokes go it was pretty cool, and the doctor sent me home with instructions to take an aspirin.
The doors are 84lbs. The thing I don't like is that the motors needed are costly. The actuators are a screw type system so they're slow going up and down, you can't just pull them down, they have to be run down so no fast enter or exit. but if that doesn't bother you it can be done. (Just my two cent)

I hear you on the credt card sized unit you carry. I have been waiting for them to get smaller also. They are a little smaller then their first units, but not like a "fob" yet. I agree, time will work in our favor.
Check with the Hoffman Group ( http://www.thehoffmangroup.com )....they have many things for hot rodding and customizing.....
These are the people I was looking at as well. They have a 110 and 120 degree door kit (so no worries about cracking your skull on the door), and ones that are automatic (even remote controlled!). I've emailed them about space requirements. Never heard back. As for the "swing out" portion, I'd imagine some sort or spring or tensioner could be usedso that would push the door open when the latch released, the motor raises the door. Or some sort of wedge piece with the proper length/angle so the door "rides out" against it. Then you get in, the motor lowers the door, and you pull the door shut click it into the catch (if necessary).
It's way down the road for me, but it's on my list too!
