Re: turbo aveo?
Let me fill you dumbasses in on how MAF systems work since everyone here is obviously a guru on MAP sensors but has no clue with MAF. 
MAF is Mass Air Flow...and it means exactly that. A MAF will read all incoming air as volume instead of how a map sensor does it with pressure. MAF based systems are actually a much more efficient setup than MAP's seeing that they can take into account different loads and variables. Only downside to turbo'ing a NA maf setup is the scaling...each MAF sensor is calibrated to flow a certain max airflow in the ecu. Whether it be g/s or hz or however else it can be scaled, you'll end up running into a problem with maxing out the NA calibration. Say for example that the stock MAF is rated for a max of 180g/s, then you slap a turbo on there and wham...come onto boost you're maxing that 180g/s and then some, say for instance maybe you're actually flowing 220g/s. How does the ecu read that extra flow? It doesn't, at least not without rescaling the maf tables. There are ways around this, but not without some downfalls. SAFC and larger injectors would probably be the easiest seeing it lets you "rescale" the stock maf sensor to appear larger than it really is to the ecu. Yeah, it lets you run more g/s flow through the sensor and more fuel, but also with increased timing. MAF's work very similar to map's in relation to timing/rpm...a certain g/s flow at a certain rpm will get "X" amount of timing, and tricking the ecu into making the MAF seem larger means that the g/s input is actually lowered...usually to where the timing is at it's highest points. And with most of today's newer cars being distributorless, this makes the job even harder...no MSD BTM for you lol.
In the long run the work you need to do in order to turbo an NA maf setup is really not worth it. OBD2 is a hard animal to play with, and more than likely you'll toss codes like tossing singles at a stripper. Best bet is to check out some chevy/gm forums and see what you run across, maybe there are rom editors similar to the one I use for obd2 Mitsu/Subaru that will work for Aveo's. As long as the ecu is reflashable, it's always a start.
Oh, and if none of this made any sense, bite me...I've been spraying cars for the past 14 hours and I'm wacked out of my mind

I already talked one kid at work out of trying to supercharge his Aveo, and it took less than 10 minutes after I started going into all the details.

Re: turbo aveo?
Why would you turbo something that has the worst braking and overall performance of any car put out in 15 years?

Re: turbo aveo?
It's not that I'm saying Aveo's are slow... that's not why they're ----. They're ---- because they're a Daewoo ripoff with the worst performance ever created. At least Hondas and specifically Civics have somewhat of a racing heritage and some intelligent thought put into the design. The Aveo is just a ------- turdball car.
