circles, pull towards. worked fine when I welded my unibody back together after cutting the rear fenders. make sure you are getting decent penetration with the welds, the firewall is a bit thicker than what I was working on.

#1 tip !!! Remove anything that you can catch on fire inside the car if you have not already . Cover all of the glass that is anywhere near because it will be permanantly damaged if weld spatter hits it . Using a flux core wire is going to be messy . It will be best if your welder uses shielding gas (75/25)argon/co2.

rhd swap? I never figured out why people do this. You can import cars that are 25 years old in the US. It would have been cheaper to get everything from an 88 silvia.
Its also dangerous to drive on public roads on the wrong side of the car. Example, passing on single lane mtn roads.
Up here we have a lot of imported JDM cars, its really not all that safe.

sheet metal is tricky to weld. if you just go to town on it, it will warp like bacon. you must weld in sections like this (all welds start on the same side, all left to right) Weld all the 1s first. (2-4 inches long) then weld all the 2s and so forth
| 1 | 4 | 3 | 2 | 1 | 4 | 3 | 2 | 1 | 4 | 3 | 2 | 1 | 4 | 3 | 2 | 1 | 4 | 3 |
you need to do a few tests on scraps the same thickness you are welding and the same connection.
welding vertical is a whole different beast as well, this alone takes a long time to master.

get a 1/2 round copper pipe that about 6in long flaten 2in of it to use as a back on the holes you blow throw this help fill them, and wont stick to the welds. as for welding fire wall i wouldnt use a flex core welder you will have more problems then anything with heat, and weak spots in the fire wall.
There a reason there not stich welded on you dont want to over strenghen or weaken the wall do to safty. If you are going to do it find all the spot welds drill them out on the car and for the doner clip grind the spot welds off on the side of metal your not useing. that way you have to only spot weld the same spots and makes clean. also make sure to prefit every thing before you weld because when you weld, and something off your cutting, and will be more of a pain then worth.
Last you need some seem sealer, and make sure to use welding primer so you dont have rust problems later.

Re: tips mig welding
I didn't noticed if anyone mentioned wire size. The mig machines usually come with .030 core wire, but you can get it as small as 0.023 or so. It makes a huge difference using the smaller core wire on sheet metal. You can run lower machine setting and run longer beads without blowing through.
