Hey Guys !!!!
Really need some help here, I don't know jack all about modifying cars..
Basically I want to turbocharge my 4ag sprinter, but don't know which aftermarket computer to use. Can all aftermarket comp can recognise turbo charge engine? Can anyone suggest some name and model to me? Please keep in mine that i'm a uni student and i don't have much money. 
Another thing.. cause i'm going for a tight-ars conversion, can anyone recommend me any low boost turbo i can use to turbocharge my 4ag while retaining the same compression..
By the way what is a waste gate used for... and would it to turbo charge the engine...
thanks guys much appreciated.........

Hate to put a dampener on things, but keep in mind that these things always cost a LOT more than you'd like them to - and if you do try and get away without spending something now (e.g. using an NA 4age to begin with), it'll cost you more later... Where abouts you live?

I would suggest doing it in two stages...
Drop a 4A-GZE in there. Prolly costs the same as a turbo conversion.
Then when you have enough money, throw the supercharger away and pop on a turbo.
That way you have an engine which was made to run boost. Much stronger, and you can run higher boost.

mrshin i live in Sydney..
I have done some research and found that the SAAB 9000CD Turbo runs on an engine compression of 9.0:1 where as the 4age have a standard compression of 9.4:1.
What a mate have told me was that if i installed a TRD gaskett it should reduces my compression and if i installed a european turbo (something like the SAAB with low boost), it would be feasible on the 4ag.

Just a thought, due to the comp ratio, conrods, etc. in an NA 4ag, the power gain/$ spent is probably going to favour putting in a 4AGZE rather than getting only similiar power from trying to add a turbo. Try it and it'll probably work, but add the cost of management/turbo/manifold/intercooler/fuel system (pump, injectors, etc.) and the whole host of other parts, (how much that gasket cost anyways?) and it'll probably horrify you

Mrshin..
How much will I be looking at with the 4agze conversion.
Also i still don't know whats a wastegate used for, and does all turbo car or conversion needs to have one.
Thanks

Yeah, I guess 5 grand is a plausible sounding figure for a 4agze conversion getting most of the stuff done - can't say exactly because I haven't done one myself. Remember also though that brakes, suspension, etc. really could do with a bit of a fiddle as well...
A wastegate is a valve used to bypass exhaust gasses around the turbo, in order to regulate boost pressure. If you have a look at a turbo at the wreckers, you should be able to work out fairly clearly how it works - without it boost would almost always go far too high. Remember that in no way does boost = power, so just boosting anything stupid will cause many problems and not make a whole lot of power...
Mate of mines got an SV21, and yes they are a tad sluggish You can add a filter, exhaust, fluro ignition leads, polish the cam covers, paint your calipers and put stickers all over it, but you're still not really going to set yourself any records down the drag strip. Only ways to get a little bit more really are:
Latest possible 3SGE conversion (e.g. beams) (up to about 150kw)
3SGTE conversion (what we'll do to his once he saves enough $, anywhere between 150-350kw, not that I recommend a 350kw camry!)
Sell it and buy a VZV21 camry (the v6 one), at least that way you'll have no legal hassles and still get a bit more poke (i think its about 125kw instead of the standard 82/88)
