anyone ever replaced the entire floor pan or had it done?

my floor is a bit rusty on the edges near the side rails but mostly dented i basically need a floor pan

 

BTW this is my project its an 88 non-turbo, it has some rust, and the floors are banged up, but i think this car deserves a second chance as a race car.

I am building a track car from it , so after i fix the floors ill install a roll cage and seam weld the chassis.

good bodies are hard to find in Puerto Rico ,and most have worst rust or are as straight as the broke *** mountain cowboy.

wonder how much would it cost to have this panel replaced by a body shop.

 

damn, well, i replaced mine in my datsun, that wasnt fun, even with direct replacement pans. basically, you have to reinforce the body with w/e before you start cutting, in able to avoid inevitable warpage.
so, without welding experience, and a good hand at cutting, good luck?
side not, dont use a plasma cutter, i learned that the hard way!

peace

 

Thats nowhere near as bad as mine!

The floorpan and rockers are available from Mazda if you want to shell out serious cash, think $650 for a floorpan.

Best bet is to beg, borrow, or steal a sheet metal brake and bead roller.

A sawzall or electric sheet metal shears work well for cutting the original out.

 

I wonder if mazda sells them. Download a full parts catalog and see if you can find them in there. I think I remember seeing them there, along with other body panels.

 

Most everything is still available from Mazda, its just way more expensive then fabing it yourself.

 

donor car to the rescue. I'd be more concerned about the framerails. They look hurt

 

yeah they have it part#FC33-53-600A this includes the frame rails.

 

Ouch. It says $1081.05 list on mazdaspeed motorsports.

 

holy crap i think i am better of giving it the hammer and just replacing the frame rail

yeah the rust is minimal but that left side frame rail looks real bad.

 

hey, Yani i sent you a pm.

 

Just put some nos on that **** yo it'll blow the floor pan right off

 

 

i am going to replace it with the floor pan from my parts car they look way beter!

 

here are some pics of Yani's project

"To replace the section of the floor that I cut out I plan on bead
rolling a rectangular sheet only in the middle and leave a 2" strip
form the edges flat. It would have rigidity and still be flat on the
edges to weld to. The rust started at the pinch weld and worked its
way outward. It destroyed the bottom 1/3 of the rocker and outer frame
rail (the frame rail is enclosed inside the rocker) and sections of
the floor pan." - Yani

"Any size between 18-22 gauge should be fine. I am using 18 + 20 gauge
for the floor pan and inner frame rail and either 20 or 22 for the
rocker panel. Just remember when your welding to keep the tip mainly
on the new metal and work small circles to minimize burn through. It's
best to plan it out so that you can keep welding underneath the car to
a minimum. I used a saber saw and an electric metal shear to cutout
everything, then sandblast or grind the rest."- Yani
