5.4kg they are. I have a set and think they are great. They have been on the car at least 4 years, only need a refurb as I left them off the car outside during the winter.
http://www.ukstarletowners.com/topic/60523-noels-auto-s-100hp-here-i-come/ That's the build thread. I'm pretty sure the 100bhp mark was passed on this or a previous one of Noel's.
Good to know Mikey, never got round to fitting them and I'm in a bit of a tight spot at the moment, so seems like a good idea to sell. They are still here guys.
Yay photos at last! Luckily I refrained from rummaging through the bargain buckets. Some awesome stuff there! Was good to meet everyone and put faces to names. Thanks to Jay for having us down.
100 bhp is achievable, keep the air box and standard exhaust. 4-2-1 of a corolla will help too. I think Noel is running an early AFC which can be picked up for about £30 of ebay.
