Default 91' V6 Miata restoration

Everything starts 6 years ago, when i bought a '91 Mariner Blue Miata 80k miles (usa spec), 1.6 115cv in Torino (north Italy)
Nice and shine, (olmost) 100% stock , beautiful color, brand new soft top..
Apparently perfect right?
well.. NO!

The car was imported from Germany few years before and this meant rust.
I knew it but it was love at first sight and decided to bought it anyway..
In my mind the idea was a very little conservative restoration to fix some minor issue but after few days i realized that i should have to change my mind.

Here some pics of my miata after i bought it

what v6 are you restoring?


the red and orange buttons on the shifter, and aftermarket radio suggest it's not 100% stock.

The orange switch is for some kind of light made from the old owner.. but i don't care for now.
The engine is a KLZE 2.5 V6 from a Mazda 626. I bought it one year ago and it still is in the garage.

Ok now let's talk about restoration first.
After one month of occasional use the first problems appears and i decided to start a little restoration but then i realised that it would be a massive restoration!

That'd be considered a clean car here in PA.

Welcome to the forum. Will this be a complete strip down or just a repaint of the bottom of the car?

Is the subframe seam welding something that helps? I don't know that I've seen it done before.

n the front side i used the original frame, on the back the rear bumper holding holes.
I'm very satisfied about the result, working under the car is very easy now!

Then i started removing all the underbody stone chip protection.








A closer look at the right subframe scratched and rusted..
