[QUOTE=rgp;709876]Anyone fitted a 17" electric fan to the original cowling hole on a pre-facelift as well as a 12" one? I have a picture of a 16" and it appears to have enough space round it to go the extra inch or am I missing something?/QUOTE]
A 17" fan will not go. I have a 12" replacement for the OE auxiliary electric fan and a 17 inch electric as a replacement for the mechanical one. As most aftermarket electric fans come complete with their own circular plastic shrouds, there is no need to keep the OE steel shroud. Just a matter of mounting the fans so they are as close as can be, within safety, to the rad.
The only problem with a 12 and 17 inch setup is that they are very tight for width. If I started again, I would use an 11 and 17, or 12 and 16 inch setup.
I built a fan chassis for my fans, they are suspended from above on an alloy square tube running across the underneath of the radtop panel, and below (demon tweek this) they are supported from horizontal steel studs I welded to the rear of the cross beam that the rad sits on. All fixings in OE rubber 'cotton reels' so no vibration sensed from the cabin at all.
Struts come upward from the beam to the alloy fixings under the fans. The extra gearbox cooler has been deleted and replaced by one in from of the rads. All works a treat. Also thanks to Grant Francis, no foam packing round the rad, so engine bay airflow much better and thus cooler.

based on the 12 inch fan I recently installed ( thread is New eletric fan, huzzah!) I would say putting in a 17 would be easy.
A 12 is actually a little too big so I had to cut the flared part so the shroud but I could still you the stock shroud. Doing the same thing on the big fan would be pretty easy and you'd avoid the fabrication greg mentioned as well as retain the efficiency of having a shroud.
