You will not get a Haltech and Tomei cams and a set of buckets and proper head gaskets and a remap etc.etc.etc. for £1000. unless you are proposing to do the work yourself. Sorry to burst your bubble mate but no point in this I am afraid.
The 1k was just rough cost of cams and fitting - cams £500 fitting for 10 hours work £500. Already will be getting an ECU and mapping, so price was just extra on top.
A lot of the american sites rave about cams and headers so it's good to hear that it's basically a waste of time, gives a different perspective from someone who's trusted in the local Zed community
My pleasure Chris, just don't want you wasting your money mate.
Please note my comments are purely based on my own personal experiences and some one may be along later with a different view but it is a lot of money for very little gain.
I just love your quote of 10 hrs labour, I can do this swop out with my eyes closed and even with my eyes open it would take much longer, try 3 times that and you are getting close.
Alex.
