There is a lot to consider when you are wanting to do it right.
You could just slap a turbo on, but there's no way it'll last.
There are ways to make it go better, but they tend to be more of a band aid, rather than a proper solution.

To do it properly, you'll be looking at quite a bit of money and time deciding what it is you want out of the car.

I had spent upwards of $5000 on my FXGT, including the car. I still don't have a clutch to suit the extra power, or a proper stand alone ECU. It was going to be run with piggy back type devices. It still has an open diff and the stock gearbox, which would go ok, but is limited to how much power I could pump out.

I bought my AE101 GT-Z for $6600, already converted to turbo. Motor rebuilt about 20,000km ago. It has the good gearbox with LSD. The clutch kit in it was over $700 (going by the receipts I've found in the car) Got a Link ECU running it (reciept for $1250 in labour for install and tune). Nice mags, brand new tyres.
It needs a bit of work still, but it's a very good base for a car that should put out about 180-200kw at the wheels when done.

well to be honest we were thinking of just slapping a turbo on and just go, as for power figures we just looking at going faster than it already is but with a turbo.....

You'll still need something to control the fuel and the timing when on boost then.

I was going to use a MSD BTM for my car. It retards the timing a set amoun per psi of boost. When not on boost it runs stock timing. It'll only retard a max of 15 degrees.

As for fuel, dunno what to do there. Maybe change the AFM, or adjust it somehow. How knows. Maybe go for a cheap extra injector setup. Powerlinks aren't too expensive these days.

this tread is awesome, im sure it was covered last week, and the week before lol, mate if you want it to be relaiable and quick then get your cheque book out.
$20k is about the mark for a professional setup 10k for reliable and tidy less than 5k is rangi mods.com

$20k on what? He just wants to turbo his silvertop. Bredon has spent about 20k or so and has bigger brakes, a crazy fuel system, the suspension stuff, new wheels and custom work to the car t make it all fit in. He's done the whole lot.
For a low boost setup, without massive power, there's no need to spend $20k on it. Hell, I'd buy a better car if it came to spending $20k on my little Corolla or Levin.
You could turbo a stock silvertop for a reasonable amount provided you shopped around, did your homework and did as much of the work yourself as possible. Stock silvertops can be turboed with the high compression, but it'll limit the amount of boost and it'll need to be tuned well.
Under $5k is not rangi mods at all. Under $5k could just be well thought out and cheap setup. Rangi mods is welding it up to the stock manifold and running no fuelling or timing control. It'll go (for about 20 minutes :lol: )

It's not always about how much money you throw at it or how much power you can make. I stock silvertop with a low boost turbo system would be a fun streetable combo. Not everyone needs over 200kw at the wheels out of their show car looking engine bay.

I say go for it and see what sort of results you can get. you might be pleasantly surprised.

Exactly, under 2k with a 4age is easily achievable and with good results.I dont know where you get your figures from..

Thing is you need to do all the work your self.

Even my exhaust manifold is home made, about $90 worth of parts if you count laser cut flanges etc. Once heatwrapped (which cost more than the manifold!) it looks mint.

the way it looks comes down to how good you are at fabricating things..

Everyone can bring it to a workshop and write out a cheque, but isn't it more satisfying doing it your self? Thought thats the beautiful thing of the toyspeed and NZ attitude. Hey look what i can do and heres how i did it, not hey look how big my loan is.

A 2k setup would see you 150 quite easily and reliably.

Is it worth spending 10X that for 90% of the people out there?

I can see why ih8tec, bazda etc do and their setups are beautiful, but i dont see why say i would need to. 150kw is plenty for lots of fun!

A std silvertop will take boost,

have seen it done before, it all comes down to tuning, and not trying to make huge HP,

But, if you dont do something with the fuel and ign, it will not last.

Std engine with a/market ecu and a turbo setup will be as reliable as anything else if tuned correctly.

That's right.
Go for it, but as Matt and the rest of us have already said, get a Link or somthing similar and tune it properly. No point spending all the effort to turbo it and only havin it last a couple of weeks or so.

i agree toyota internals are pretty good. i have a standard non-turbo motor in my car running 20psi boost. (has had a lot of dyno time)
it comes down to a good tune and nice cold air.
current cars:
Evo 4 230Kw atw
1971 mini.
79 bugeye 245kw atw.
Evo powered mx5 under construction
