    Figured now I have the bits laying around before I put them in my engine may as well post some pics for those intrested in sets of cams.
    hopefully there will be some dyno results in the next month or 2 and also peter kennard is writing up a spec card for this specific regrind which I should have tomorrow, will post it ASAP

    End of each camshaft is marked FI (front inlet), FX (front exhaust), RI (rear inlet), RX (rear exhaust) as well as the duration and lift (262, 9.8 respectivly)

    My complete set of cams to be installed soon

    would harder valve springs reduce performance sue to being harder to open? or is it nothing to worry about, dont you usually need them more for high reving cars? or am i completely wrong haha

    while im sure they would in fact have some negative performance impact in terms of engine efficiency/drag on the camshafts.. I doubt in the grand scheme of things it adds up to any remotely noticeable amount compared to the rest of the load on the engine.

    the frictionional loss is very minimal as our cars have roller rockers and as one set of valves is being pushed open another set of valves springs elsewhere will be pushing the cam lobes around in the same direction almost cancelling any losses on the engine.
    and peter kennard said our stock valve springs are so soft that he thought that just changing the valve springs would yeild a small (1-3hp) gain in top rpm power as the valves would accually be sealing correctly!
    but of course once the cams are installed in conjunction with the valvesprings the power gains will outweight any losses hundreds of times over

    Cam Spec sheet

    For those intrested in the exact numbers here is the exact spec sheet for the cams, and the numbers for valve movementl (as cam lift and valve lift are different with our cars having a ~1.7 rocker ratio)

    Did anyone get a cost for postage of a set of 4 cams from uk to nz, and a cost for postage of 4 cams and a set of springs from nz to uk?, how much was it and are there taxes both ways?.
    (anyone know if there is an option with taxes when you are sending something to be machined?, or do they just charge as is it was a new item bought separated each way?)
    I'm interested, just trying to get all possible costs and taxes sorted out.
    Although I have a spare set of cams it may work out cheaper for me to buy cams from someone over there depending on cost for sending cams from the uk. Any thoughts

    as long as you put on the package that its is a gift to the person receiving it I think you can get away with a bit of tax dodging. because technically I am not selling you anything, peter is selling it to me and im forwarding it on...
    Im not sure on the matter though maby someone can come along and shed some light on the subject
    as for postage only swinks from the UK has expressed real intrest in getting some cams done but is waiting for funds later in the year so no postage has been discussed but for me to send 4 cams (excluding cam gears) and 24 springs to trent (lathait) in australia from NZ I think cost a little under 70NZD

    Also will start compiling a definitive list of people who are intrested

    Europe
    -Swinks (october/november)
    -MarkSanne

    New Zealand
    -Adie (August)
    -Gly (when ever suits)
    -thefelipeth
    -wintertidenz (possibly)

    Australia
    -

    If your name is on the list can you please specify when in the year you will be intrested in getting your cams ground if I havent already stated and if you will need to purchase cams or you already have some spare

    I will be PM'ing others on the list and seeing if they are still keen. as said a few posts up 2-3 sets at a time is ideal for peter so it doenst disrupt his other work to much so I can effectivly split this 2nd group buy into a rolling group buy (could a mod please change the title to GB: Rolling group buy 264 cams + Valve Springs)


    carls (Patryn999) galant has had his cams installed so he will be wanting to get rid of his standard cams to the next lot. also scott may be intrested in selling a set, they are both local to me here in chch. Im pretty sure Taupodrifta has a set for sale in NZ also. thats all i know of short of those 3 you will have to source your own cams.

    sorry dont have kitchen scales at my flat so cant weigh the cams and springs i have sitting on the table next to me, but if memory serves me right the cams and springs i sent to kenneth on thursday weighed in at a little over 6.5 kg. cams are around 40cm long just by using my "eye"crometer and the box the valve springs come in is about 25x15x5 cm
    hope this helps

    taking the engine out? doing other stuff aswell? or is it not a case of just pulling the out and putting the new ones in?

    you can install cams & valve springs with the engine in the car (thats how I installed the first set in carls galant) but i am installing an evo gearset, as well as new bearings and seals in my gearbox. + cams + lifters + valve springs and now needing a new clutch so takiing the entire engine out is mimimal extra effort to taking out the gearbox and makes the cam install much easier.
