4AGE modifications

decided to keep my car for the time being
at the moment all i have is a pod filter with that blue hard rubber piping that people have for intercoolers, and so im thinking about cutting a whole in the bonnet directly above where the pod sits , then putting that hard chicken wire stuff ( well its not chicken wire, people have it at the front of there cars 2 hide front mounts etc) over the whole with a plastic outter bit (? i cant explain shit , sorry)
my mate has this , not on a rolla , but similair car and it looks great and i imagine it helps with air flow
just worried does it matter if the pod gets wet? and its next to the battery , wat if that gets wet?
okay , now what else can i do ? and plz dont say..exhaust , cams bla bla....i mean like WHAT exhaust exactly , WHAT cams...
and in what order..

you don't want the pod getting wet as it will fall apart! unless of course it is a good K&N or something that are designed to be washed, but all the same you still don't want it soaking. I have seen the pod being installed inside the LHS fender where the original pipe work went. This will prop give you better protection for the pod and colder air.
The hole in the bonnet will tend to suck hot air out as air goes over it. Unless it is more of a scoop, then it will push cold air in. Either way it is OK.

Get an exhaust, then cams 
Dont bother cutting holes in your bonnet, it wont gain you f**k all power, and it will look ghey. Dont bother trying to get more/colder air into the engine without the ability to remove the exhaust gasses ie. get extractors and an exhaust. Go to an exhaust shop and get them to make you some extractors, and a 2" or 2+1/4 or 2+1/2" inch exhaust.

Mods to 4AGE depend on how much money you want to spend and what type of 4age it is.
Don't know what kind of car its in but I'll assume its standard.
Start with suspension and ensure everything is right for you such as height, stiffness and damping rates etc etc.
Engine wise start with intake and exhaust. If you have a pod filter make sure you have a decent cold air intake. Hot air from engine bays suck power.
Exhaust-wise, you probably won't need extractors as the general consensus is that the factory headers are quite good. For a 1.6 4 cyl you won't need anything bigger than 2 to 2.25 inches.
As for internal mods like cams you can't modify too much with the factory computer. Go to Bill Sherwoods site and check it out. He knows pretty much everything there is to know on modifying these engines.

wet pod = BAD, air will not be able to get through as good, and if the water soaks through the pod and gets into the inlet you will have problems,
as said just work on exhaust and suspension to begin with

in regards to the pod, i am yet to see actual gains of having a so called "pod filter" in your engine bay.
why not get a k&n panel filter, put it in your air box. then run some cold air ducting from the bumper or gaurd? This is the way i will be doing it...

Must cut hole in bonnet for 230 watts more power...
Honestly man, Holes in bonnets do nothing, Go buy some cams or a decent exhaust...

WRX's have vents in the bonnet to force air through the top mounted intercooler...
Unless you have an engine that can suck down litres of air a second, Bonnet holes or vents serve no purpose, UNLESS the vent is angled to let air flow through the radiator/intercooler better...
Im not 100% sure whether the Standard ECU can cope with aftermarket cams...

One word.... HOMOLOGATION. this allows them to utilise these when building rally cars, ie the hole there, we now can play "use the rules" game when building a car.

well in this circumstance yes, having a car parked, pissing down ran and a big hole over it, get wet, sure... I the raly car we always have used pod filters. We get cold air through the wheel arch, which in the AE10# a hole is already there, just remove the dust/resonance box just behing the bumper, get a VN intake pipe (The bit that is bolted directly to the air box), drill four holes, bolt this on, a bit of pipe that runs to the bumper, and run done!

By no means, all changing the rear half gives is a 5hp increase in power and alot more noise.. the headers is where all the power is hidden so change both.

1.Exhaust. unless a custom jobbie.... well there are many to choose from and all work well, so that's abit of research you'll need to do.
2. Pull the head off, port job, may be a shave, but definately get a TRD gasket($150), this will give you a bit more comp, good springs, put it back togther with some B/P cams if you have a S/P 4AGE
3. Save for some decent cam with gears and an A/M ECU, Mircotech etc, most are the same these days. Injectors, fuel pump.
4.somewhere do suspsension and brakes...I like doing this stuff 1st, because I'll prefer handling and breaking over power. It's fun being able to pull away from faster cars into and out of corners, and watching their faces trying to figure things out.
5. finally things like quad throttles, etc this is going to cost a bit as fabrications are necessary.

outrun, you have asked for help, people have suggested that cutting a hole in your bonnet may not be worth while, then u make smart arse comments that are actually making u look stupid...
the large main vents in the centre on evo's are for venting the hot air out of the bonnet.. as are the small ones on either side of a wrx bonnet... which is what yours will do if you cut a hole and dont have a scoop, maybe causing more hot air to travel past the pod than before... as far as aftermarket cams and standard computer go, yeh im pretty sure u can get away with 264 duration.
With extractors you gotta decide if u want low end or high end power, 4-1 extractors good for high end power and 4-2-1 have better low end torque, i think its round that way anyway... 
someone correct me if im wrong
