2J cam gears

Just curious if anyone here has adjustable cam gears on a 2JZGTE, and if so what settings do you run and with what results over standard timing?
I'm told spazzing 2 deg on the inlet and advancing 4 on the exhaust is the way to go. Yes... no... maybe... ?

Don't dick with the cam timing unless you have programmable engine management, and the time/motivation to experiment with different settings on a dyno. Frankly I wouldn't bother. 
Oh, and if you get adjustable gears, don't get the HKS ones! JUN gears are apparently good though.

I always thought that cam gears can't really do that much except move the power band around. If you still have the same duration cam 233deg or whatever it is, then all you can do is make air go in or out of the engine a couple of degrees early or later. But in the end you still only have 233 deg cams. For the price of cam gears, I wouldn't bother. But some longer duration cams that don't have too much lift so you won't need new valve springs and retainers and then have much greater time with valves open. That is what I plan to do anyway

I heard the HKS ones wear on the teeth - is this the only reason to avoid them?
As for dyno-time/motovation to mess with the settings, that shouldn't be a problem either.

4 horsepower its worth, seen my tuner root around with another customers soarer for an hour, 4 horsepower. pretty pointless with standard cams

I dunno dongah.
I watched a dyno tune on a 2J still with standard ecu, and they managed +8 rwkw and were still going when I left, just from a set of HKS cam gears. MK4.com also seem to think that 10kw from cam gears is not unreasonable.
2 x cam gears = $350
+ 10 kw
= $35 per kw
vs
2 x camshafts = $1250
then you need a new ECU
1 x mid-range ECU = $1500
1 x ecu tuning = $500
= $3250 total
Now lets say you manage to get an extra 50kw
= $65 per kw
You would need to make nearly 100kw extra from cams and ecu on a stock motor for it to be a "better investment".

Add to that the fact that I DON'T WANT 300 rwkw. I'm quite happy with 250, and I'm quite happy with the fuel economy that I get from a standard ecu with standard cams.

130ea is a bit crazy. thats about $20 worth of alloy, and maybe 1hr machine work 
$130 pair is a good price exchange
$185 pair is what id call reasonable exchange

Dunno, if you're the small percentage on here who can make these yourselves or have a mate that can make them, then sure you can get them cheaper, but for the vast majority of us who don't have those contacts or resources, buying them is the only option.
Now if you're happy to pay $300 each for a brand name, sure go for it as I had to in the past, but if you want something in between that is reliable and well made, then this is an option.
Note that I've been reading on here for a few years about how easy and cheap it is to make these, yet I'm yet to find any info about them actually being made and made available to the public.
I asked John to make these for the 1JZGTE Soarer guys who have swamped him with interest and orders but also thought some on here may benefit - my apologies if I just wasted bandwidth.
John is offering these at cost in the hope that he will occasionally be paid to fit the odd set and tune the odd set on his dyno.
In the meantime if it's supply only on exchange, he's only helping the engineer who jigged up, made the centres and batch machines the outers pay for his overheads and pay for his time and in turn put food on his family's table - great if he just wants to support the local engineering industry instead of sending the work to China, but of little personal financial benefit.
Either way, if my post is of no general use to the masses, feel free to nuke it.
