A BEAMS conversion counts as an illegal modification while still on your P's. "Any modification that improves engine performance", VVTI would come under that.
 
You have a year until you're on your opens. I drove my turbo around for around two years while still on my P's. Just don't go lapping town on a Friday night and you'll be right.
 
It just seems like you're wanting to spend money on an inferior car with an inferior engine, while still breaking the same laws.

 
I can't see that as an illegal modification. Its not a massive power increase, its still the same displacement and naturally aspirated.
 
As I read it the law says, "Any modification to the engine that improves/increases performance"
Well, he's not modifying the engine, its a standard engine sir. Just replaced the same capacity of a worn out one.

all im saying is you can get more out of a turbo with less money than you can get out of a N/A.

You'll get more HP out of a turbo with less money, but you won't necessarily mean you get more performance.

Big claim my friend lol. I'll let the cars do the talking next track day or Mt. run, then we'll talk ;)
I think an NA could match a turbo in a corner due to less weight both on similar suspension with the same driver

keep dreaming buddy..with the same driver the turbo is going to win hands down (and im not being biased here either).lol
and yesh would ahve taken you up on that offer, but i have to be carefull what i do with my car from now on cause of personal reasons. so no track days, big mods etc anymore. its either drive it as is or sell it (which i dont want to do)

My old N/A was awesome. A nicely powered and handling car to learn with and have a lot of fun. But not in any situation, on any day would I trade my turbo for one.

Thats what i have to say as well after driving the N/A, theyre fun for sure but i just prefer the turbo. everyones tastes are different i guess.

would have thought more HP= more performace/fun in the right hands...

Yeah cause he owns an N/A hehe.
Anyways I think we have established that you going ahead with the N/A for the time being, considering you change your mind a bit.
So lets concentrate on the N/A you have just bought and try and get that up and running properly and up to scratch so you can start having some fun.
Cheers
 

Quoted from the RTA website
 
Vehicles – You must not drive any vehicle with:
Modifications that increase engine performance.
 
A BEAMS conversion is a modification to the vehicle in which engine performance increases.
 
Hell, no cop is going to pick you up for it, so go for it. But from my experience, no cop is going to pick you up for a factory turbo either.
 
Whatever makes you happy, but my guess is you'll get over the BEAMS quicker than a turbo.

HP is just a single part of the equation and more of it doesn't always return more performance (Or muscle cars would be the fastest things ever).
The big thing to look at is weight. With a turbo, you have a heavier gearbox (to handle to higher HP), heavier drive shafts (to handle the higher torque), heavier brakes (to slow down from the faster straight line speeds, heavier car), heavy turbo assembly (to make more power, to push the heavy car), heavy intercooling assembly (to cool the hot turbo to keep the HP up), heavier wheels (to fit bigger tires for more traction), heavier tires (to get the power down to the road.
 
All this weight works against the car when it tries to turn (Inertia is a bitch), and this is where the NA get's it's advantage. If you took two cars, exactly the same in every way, chassis, tires (lets say 205's), wheels, brakes suspension) except one is NA, the other is Turbo and 150kg heavier because of it. The lighter NA will be able to take corners faster due to having less weight, less corner inertia (the force trying to make you not turn) and will be able to stop quicker (less mass to slow down).
 
In a back of the envelope example*. At Wakefield, a turbo might do 240km/h down the straight, but has to brake 100m from the corner and then can only take the corner at 100km/h or it slides/runs wide. The NA only gets up to 180km/h down the straight, but can brake 50m out from the corner and can take the corner at 110km/h without issues. If both cars come onto the straight doing 80km/h, the Turbo will pull a 50m lead before braking, the NA then winds all that distances back in while the Turbo is braking, before standing on the brakes itself, and then it will actually over take the turbo through the corner as it maintains a higher corner entry and exit speed.
 
This might not work as well at places like Eastern Creek where the track is a series of massive straights, where HP certainly carries a big advantage (although, lower weight with adequate HP can tip the scales. ie: 1000kg + 400HP can trump 1250kg + 600HP)
* My numbers are probably off, but it's just a rough example.

 
 
Its your car Gatesys - you've driven an Turbo (be it for a very short time) and driven a NA
 
 
Have you driven a worked (mr2) NA or a worked (mr2) Turbo Motor
 
I personally haven't so cannot hold judgement. Before you rush out and buy parts I would definitely try and source a test drive (or passenger seat joy ride) in someones car.
 
All of these downsides you mention of a turbo, I have had none and I have used my car on the track on more then once occurrences and I know for a fact previous owners have done the same.
 
 
Spend the time, get this up and running like it should and move on from there.
