rvannly Posted May 30, 2009 Share Posted May 30, 2009 So I finally found some time to work on the Z. I started off by taking out the carpet and dumping it. I noticed a lot of rust chips and so I proceeded to chip off the old sound deadening. I was pretty dissapointed when i started to see light through the floor. So now I'm in need of new floor pans. This lead me to my first question. Are the OEM floors two layers? It seems like I see two separate layers. Yet, when I was looking online for some new floor pans they are only a single layer... Any input would be appreciated thanks. My other question is about the repair. It seems that the front (towards engine) portion of the floor pan is heavily rusted, but the rear section, towards the seat was somewhat preserved beacause of the stock sound deadening material. Should I replace the whole floor pan or just the section? If this will save me some money then I'll try that route. Unless of course there's a good reason like, mixing old metal with new.

evildky Posted June 1, 2009 Share Posted June 1, 2009 the floors are just one layer, the rust somtimes flakes off in layers, I have no idea why Quote Link to comment Share on other sites More sharing options...
jkgts1 Posted June 1, 2009 Share Posted June 1, 2009 I think the decision to replace the whole floor or not would be one you need to make. When you get it all stripped down to bare metal you can look at the whole thing. Obviously you would not replace the whole thing if there are just a few rust areas. Also depends on your perception of "little" or "a lot" of rust. Little rust to you might be a lot for someone else. You have any pictures? A picture is worth a thousand words. Good luck.

trwebb26 Posted June 5, 2009 Share Posted June 5, 2009 Be very careful how you proceed... That long "strip" of rust on the right side of the picture that goes with the length of the car - that is the top of your frame rail... If you think you are going to just replace the "rusty places" - you'll end up doing a mess of work if you expect to do it "right". What are the goals for the car?

rvannly Posted June 5, 2009 Author Share Posted June 5, 2009 Yeah you are absolutely right. I did some more cleaning of the area and it's much more worse then I thought. I'm going to have to replace the entire floor pan and frame rails. As far as goals for the car. Right now, it has no transmission so I'll just start off with a motor swap from the get go. KA24de ITB turbo. Probably 250hp. I'm thinking for the floor pans and rails, sheet metal and square tubing should be enough right? 20gauge? Thanks for the input!

Don't just think that a KA swap is going to t be as easy as you might think. there are some engine mechanical issues that you have to contend with. Like dealing with the front sump clearance issue and some others that I rather you find out on your own Quote Link to comment Share on other sites More sharing options...
Turbo7MN Posted June 7, 2009 Share Posted June 7, 2009 If you have intentions of driving the car, and driving it hard you really need to fix the rust properly. My guess is that when you clean it up and cut out the rusty bits of the floor you will find the frame rail to be rusted and structurally compromised. If you don't fix this properly you will be compromising the integrity of your entire chassis. Quote Link to comment Share on other sites More sharing options...
gmac708 Posted June 9, 2009 Share Posted June 9, 2009 I just replaced the floors in my 70 240Z. The multiple layers are where seams connect the floor to the front, rear, and frame rail. The frame rail only goes part way back. Here are some pictures. Start on R/H side Drill spot weld and remove seat brackets. Remove old floor (this shows new Bad Dog rail being installed) cut fit install floor Repeat if necessary.. View of installed Bad dog rails (they extend all the way to rear suspension supports). Hope this helps. Gord Quote Link to comment Share on other sites More sharing options...
blairjj Posted June 9, 2009 Share Posted June 9, 2009 Gord, Were your floorpans from Zed Findings? Do you have any closeups of where you trimmed along the trans tunnel? I've been chickening out on patching mine, my 72 is orange and looks very similar to where you just patched (except you have a battery box/firewall where as I do not). I've had the Zeds and a fullset of Bad dogs for like 6 months... just can't seem to get out there and get them in. Thanks, Jay Quote Link to comment Share on other sites More sharing options...
rvannly Posted June 9, 2009 Author Share Posted June 9, 2009 gmac708, That looks great good job! They do look like zed pan and rails, are they? Many thanks for the pictures. Too bad I can't use the zed findings floors since my rust extends beyond the edges of the zed kits. Looks like, from the underside picture, you're going... RB?

Cobra_Tim Posted June 10, 2009 Share Posted June 10, 2009 Floors look like the Zed floors, but the rails looks like something else. We're currently installing new Zed Finding rails and pans in our IT car, awesome pieces... Quote Link to comment Share on other sites More sharing options...
gmac708 Posted June 11, 2009 Share Posted June 11, 2009 The floors are Zedd Findings and the frame rails are Bad dog. Here are some more pictures around tunnel. C'mon BlairJJ....doooo eeeet:mrgreen: Quote Link to comment Share on other sites More sharing options...
Cobra_Tim Posted June 11, 2009 Share Posted June 11, 2009 Did you find the rocker side of the Zed floors to be a bit too high? We had to reshape ours somewhat. Quote Link to comment Share on other sites More sharing options...
gmac708 Posted June 11, 2009 Share Posted June 11, 2009 If you call standing on them re-shaping, yes. I did have to do that . The seat supports did not follow the floor either. Floor ended up flat where it needed to be. Quote Link to comment Share on other sites More sharing options...

Xylemer Posted September 23, 2009 Share Posted September 23, 2009 GMAC708, your original pans look 10 times better than mine. I would be happy to use your old ones. Quote Link to comment Share on other sites More sharing options...
rturbo 930 Posted September 23, 2009 Share Posted September 23, 2009 GMAC708, your original pans look 10 times better than mine.

gmac708 Posted September 24, 2009 Share Posted September 24, 2009 Seriously. gmac708, why did you replace them? It doesn't look like there's anything wrong with them. The new floors do look good though, good job. Well... They did have a few holes in them, some areas were pretty thin. It looked like the floors rusted from the inside-out. It might have been moisture from wet carpet or something. The photo's don't really show it and I never took any pictures specifically of it. I did stare at them for quite a while, trying to figure the easiest way out, eventually figured, WTF ?!?! I planned on adding the Bad Dog frame rails because of the RB swap, it didn't seem like that much more work to replace the floors. It really isn't that hard to do. (except for the burning skin and hair from welding upside-down) Quote Link to comment Share on other sites More sharing options...
1976Z Posted September 25, 2009 Share Posted September 25, 2009 Looking good!! Quick question, I have the zedd findings pans and rails. The rails that they come with only cover the area under the pan. I need the entire rail up to the TC bucket. I really cant tell fron the pics, do the Bad Dog rails weld directly to the tc bucket?? Thanks!! Quote Link to comment Share on other sites More sharing options...
gmac708 Posted September 26, 2009 Share Posted September 26, 2009 The Bad Dog (BD) are bigger and fit over stock or Zedd frame rails. Here is picture of BD over stock. I chose to leave out the stock / Zedd and just go with the BD. Here are some photo's during the install of the Bad Dog frame rails. Hope this helps Quote Link to comment Share on other sites More sharing options...
