scaotty Posted September 28, 2010 Share Posted September 28, 2010 Im thinking of cutting out the spare tire well, to allow more room under the car for dual exhaust. Any thoughts or experiences with this particular project? Also thinking about doing an aftermarket fuel cell instead of the factory fuel tank.

Mike kZ Posted September 28, 2010 Share Posted September 28, 2010 It's easy, cut out the spot welds Quote Link to comment Share on other sites More sharing options...
gmac708 Posted October 1, 2010 Share Posted October 1, 2010 (edited) ...that was easy Now for the fun part And then cover it up... I am not quite finished yet but it looks like it will work. Keep it as high as you can. Remote fuel fill would still be an option (hidden behind license plate). I am going to shave original fuel cap fill door. I hope that helps.

ModernS30 Posted October 1, 2010 Share Posted October 1, 2010 ^^ very clean install. I wish I had done my fuel cell a little more professional. Quote Link to comment Share on other sites More sharing options...
mr jdm Posted October 14, 2010 Share Posted October 14, 2010 maybe its just me, what prevents the cell from moving side to side? Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted October 14, 2010 Share Posted October 14, 2010 I'm in the process of removing the spare tire well also. One thing that was pointed out to me (I plan on keeping the stock tank) is that the tank presses against the tire well, so if it is removed, the tank won't mount properly. One thing I'm noticing for myself is that the drivers side strap appears to be welded to the tire well, so if you cut that off, no more strapping point (correct me if I'm wrong). I assume that installing a fuel cell involves more than just mounting it in place. Fuel outlet lines, I assume, are different size than stock and mating it to the stock fuel system may be an issue? My tire well was completely rusted through, that's why I'm doing mine. If you don't need to remove it, I would advise against it. Quote Link to comment Share on other sites More sharing options...

sweetride2go Posted October 16, 2010 Share Posted October 16, 2010 I cut out mine as well, and immediately had to consider the OEM mounting points since I decided to use the original tank. I also modified my tank, adding 5" to it. I wouldn't recommend this to anyone. I would have been spent way less time fitting in a fuel cell. This shows the metal I added. I MIG welded it, pressure tested it, and ended up with 31 leaks, haha. Eventually I took it to my brother who is a great TIG welder, and we fixed it all. Since I used the original straps, I need that hanging point from the peice mounted to the spare tire well. I took some measurements and ended up making this... I also modified the cross-member so I would have more clearance with dual exhaust. What I didn't show is the upper brace for the tank. Since the original tank was 'pulled up' against the spare tire well, and mine was no longer there, I took some 3/4" square tubing and mounted it horizontally front-to-rear, adhered some rubber, and everything cinched up great. I am still using this set up today. In hindsight though, I would never try this again. A fuel cell would have been easier, and more functional. Someday I will probably take this out and replace it with a cell... Cheers Ryan~ Quote Link to comment Share on other sites More sharing options...
sweetride2go Posted October 16, 2010 Share Posted October 16, 2010 PS: If you were to just cut out the spare tire well for clearance, etc., then that isn't such a big deal. Making the mounting points and such wasn't that bad. I just wanted to be clear, that modifying the tank ended up being a PITA. Quote Link to comment Share on other sites More sharing options...
