I will be organising a group buy of cam regrinds via kennely cams @ $630 NZD for all 4 camshafts
http://www.kcams.co.nz/Menu/Home.php
Peter kennard, the man who runs the above mentioned business is the man who used to design cam profiles for kelford camtech, now he runs his own business here in christchurch
the numbers told to myself by peter were taking the stock cams to 264 degres of duration @ 0.1mm lift. and bringing the overall lift of the cams to 10.5mm this is a huge step up on stock cams and even out performs the RPW billet cams (272 advertised duration @ 0 lift and 8.5mm overll lift) these RPW cams retail for $2300+ NZD almost 4 times the cost

some people may worry about removing the hardened surface from the working surface from the cam lobe., this is not an issue as there is no material being ground off the tip of the lobe which is the part of the cam which does all the work. ie the part that needs to be hard.
the only issue with this is because the cams have so much lift they require the valve springs to be changed to ones which wont bind. but again as mentioned in the thread linked above evo 4G63T valve springs fit which peter can supply at $345NZD for a set of 24 springs
the valve springs can be easily changed folowing the guide below

the valve springs can easily be changed without taking the engine out of the car or even taking the head off the engine, saving hundreds and hundreds of dollars on head gaskets and lots of time
so far the list of intrested persons is a follows
-Myself
-Carl aka patryn999
-Kenneth (maby)
the more people intrested could possibly bring down the cost of the regrind and possibly the cost of valve springs also. please register your intrest I look to complete this by early febuary
