    do you think that it is a good idea? You always must open that tank to check if you have enough water inside.
    If you must check that during/right after driving you can't open it due to the heat...


    okok it looks cool in the engine bay.....but functional?

        Jon at 666fabrication may have what you are looking for: http://666fabrication.com/bmw.html

        He only lists an expansion tank for the early m20 cars but may have or be able to make one for the S14.

                  On a track car using water and water wetter, you can't see anything even with a new resevoir, so an aluminum tank won't make any difference, accept a little piece of mind.

                    Is that a 13lb cap? Brand of cap? Is it taller than the stock tank overall, meaning, if you level-set the two tanks at the bolt flange on the passenger fender side, are they the same height? Is there a mounting flange on the back side, like the stock tank? I can't understand why VAC hasn't posted pictures of this on their own site yet....

                      Not sure on the brand, pretty sure its a 13lb cap the new tank looks about half an inch shorter but i havent mounted it yet to see how far off they are from each other but does seem it could hold more coolent(could be tricking my eyes) and yes theirs a mounting bracket on the back of the tank like the stock one and i have no idea why they dont have a pic on their site because it is some great work they did here...then again this is in my opinion

                        Hey Guys,

                        Yes this product is available. I wanted to tweak it more before we sold any, that's why there are no pictures... but 'livenmoreuro' convinced me to sell him one
                        I wasn't in love with not having a level-sensor as part of it and wanted to spend more time making it look a little more OEM than it does... because I am as picky as the next E30 M3 guy.

                        Right now its a solid piece, plus no bursting in the heat like the OEM ones.
                        I was hoping to bring one up to the S14 motoring meet to show people in person. Hopefully I can make it as I know there are too many scheduling conflicts for VAC as a whole to attend.

                          I love most of what VAC produces, but here I gotta say I don't get it. Paying $250+ for an aluminum expansion tank that arguably does not function as well as the $80 factory one seems a little odd to me. I do like being able to glance at mine and see that the coolant level is where it should be....and I was not aware that the plastic ones were having incidents of bursting....

                          The aluminum tank does sort of have the "hand-fabbed racecar" look to it, but IMHO you are paying a lot and giving up a lot of functionality to get that look.

                          But what do I know? I am still using the stock radiator and am 100% satisfied with that....

                            can we get it to carry a little more liquid? in the same space

                              I love the way the AL tank looks but I also like to monitor the level of the coolant at a glance. One can add dye to a water-Water Wetter mixture to view its level inside the plastic tank, if need be. I'd also imagine the stock tank weighs a little less than the AL tank.
