IMHO:
If you change the inside of the engine, you will definately need to change the computer. If its external, then there will be more/less boost the computer should handle it, but if its changed inside (especially if its "wild") then a re-map will be needed.
If your looking for an extra 15kw look at getting it tuned for AUS fuel first. This could give you that 15kw!
Also, if your head is good (ie. not blown) DON'T TOUCH IT. Soon as you start playing around in there your more than likely to "bump" something.
Start external to your engine, if you blow something internally, then start looking internally. Cars with boost get better power increases from more boost/cooler air than by changing the duration.

I will have the engine tuned after all my mods are done. I want every extra kw i can get. not just from tuning, but cams, boost, exhaust etc. I'm not "just" looking for an extra 15kw, I am exploring every option to gain power. More boost and cooler air is on the agenda for next week too. It is booked in for a full 3 inch exhaust system and also cold air intake.
Oh, and the cams have nothing to do with the head gasket, they are just under the rocker cover. Bumping something doesnt seem like an issue with replacing cams. It is a very easy job.

Thinking about it again now, you don't need to take the head off, your right.
As for cooler air I meant bigger/better intercooler, re do the hoses to it (esp the hose that goes from the inner guard to the intake manifold as its squashed to get through the hole in the guard).
3in exhaust (dump pipe back) will be a definate help.
The Mk3 supras have a cold air intake system that dumps cold air where your airbox sits (and where my pod filter is kinda stuffed into), if you made a sealed box over that hole then it'd be a great cold air system.

I have a guy making all stainless piping for my intercooler at the moment. I am putting off the idea of a bigger intercooler for now, but i think it will eventually have to happen.
celicamad said a airbox from a VT/VX commodore is the best he found.

My Supra is going to be off the road next week to get the clutch done, so I thought It would be a good chance while it is at the mechanics to put some decent cams in.
What cams should I put in the 7MGTE to gain extra power or acceleration ?
I heard the NA 7MGE cams give gains of around 15KW. Is this true ?
Can I get my own cams ground ??? can this be done ?
Can my standard computer handle lumpy cams ??
Any advice is appreciated.
Thanks.

Cams are exxy. Longer duration cams will require the lobes to be welded and ground. This will set you back around $1000 for both cams. Cam people I would recommend you talk to would be Tighe Cams, Wade Cams or Clive Cams. These three companies have extensive motorsport experience. DO NOT UNDER ANY CIRCUMSTANCES DISCUSS THIS WITH THE IDIOT MECHANIC "BASRA" THAT TOLD YOU THE R154 AND THE V160 BOXES ARE IDENTICAL.
Your standard computer should cope with cams of up to 270 degrees advertised duration. However, your valve springs will not tolerate in excess of 8.5 or 9 mm lift - they will be coil bound (speak to Ed ma61 - he has done tonnes of research on this, or Stenno, who actually has some TRD 7MGTE cams, valve springs and shim under bucket setup for sale). So if you want more lift, you'll need new valve springs. If you go for more than 9 mm lift you'll also need to go shim under bucket. That'll set you back another $1000. However, does your head flow enough to support cam lift of greater than standard lift? Have you had the head on a flow bench? If Toyota follow tradition, the exhaust side will flow like a blocked intestine. If you have not done any work to remedy this, increasing lift will be a waste of time. So then you need to whip the head off and get it ported. Another lazy K.

I want wild, not mild, but dont want to spend shitloads of money.

Mutually exclusive. 'Wild' will require an aftermarket ECU. Add another couple K.
Mmmm......might just put some cams in......

If you want cams, speak to Stenno. He's asking $1000 for his TRD ones (new) and they're HUGE. They will work fine with the stock ECU, but you'll probably get the best results later when you fit a computer.

Wouldn't the Turbo A cams be better than the 7MGE ones anyway?

Yeah, I found out my cams are better than standard 7MGTE, but I want MORE !!!! I'm trying to find out what I can get, so when my original cams come out, we can check them out, and get something even better. I might be able to sell my original cams to someone here on toymods, depending on how much better than standard they actually are. But if they are already pretty good, I wont bother, unless I go for TRD cams.

I wouldn't go cams yet, maybe down the track.
Do things you'll get big gains out of and increase engine life.
IE an aftermarket ECU will be a big, big advantage especially in stopping detonation which will inturn stop your head gasket from blowing.
There's plenty you can do before going internals, mine are all still stock and i'm getting some decent power.
Go ECU, electronic boost controller, T04E hi flow, better intercooler in that order and you'll see big gains.

dude, nothing to do with lift...
the difference is in the duration of the intake cam, shifting the power band up the rpm range some, and giving you more top end power.
might not notice it, but if there's duration, there is power hiding somewhere in the rpm band...
Cheers

So can I get some conformation on these 7MGTE TRD cams that Stenno has please ??
Is it true they wont fit straight into my 7MGTE head without further work ?? ed_ma61 ???

yep, head needs work 
however, stenno has an entire brand new built 7m with all the prep work for these cams done for sale too. maybe he'll separtae the head??

that said, for the $1k stenno wants, you can also get a set of totally custom rods ground from clive cams, to 'your' spec that wont require any head mods...
and the same deal i PM'd you still applies

So Ed,
On saying that the difference is in the INTAKE cam.... are both the intake and exhaust cams different sizes? when i put them in my car i thought that they were both the same and just chucked em in! Couldn't see any markings on them to tell me otherwise
Errrrr... doh?
Car's been running alright though! except for my cracked radiator hose, otherwise no issues. Please don't tell me i have to pull that #$%^& engine apart again
