Never heard of this little beastie, please enlighten me, what is is , or am I not ony old but dumb.
I think the Garret T10 kit would put too much backpressure on the motor. If you want to get into power adders you should look into nitrous.
If you start on it now you might have it dialed in before I die of old age, better hurry tho.
I really don't think the Blasty would hold the powwaa, not to mention there's not enough "meat" in the cases to "O" ring them to hold the extra pressure.
Be my guest and prove me wrong.

Before I for one second believe he A: Has a Blaster or B: Has a complete Turbo kit for anything other than a homelite chainsaw , I need pics ...
k since you have no idea what your talking about ill enlighten you. i have a decade of turbocharger experience. you will NEVER finish this with a solid result. and now the reasons why.......
1. this "t10" you have, if its even real and not a cheap chinese knockoff. is too big for a 200cc 2stroke. it flows around 150cfms. the t10 would be more suited to a yfz450 or 660r. a good turbo would be the b series off a 80's 650t 4cyl street bike as it flows around 60-80cfms. also your charge lines would need to be around 1- 1 1/2inch dia. anything bigger and youd loose all your pressure.
2. a 2 stroke can fry or detonate its self just because of a improper fuel/oil/air ratio. which means the margin for error under boost is almost impossible to deal with. how will you control the fuel to kick more fuel(correct amount)under boost or at partial powerband, you basically cant. with out a extremely, extremely expensive fuel injection system or fuel control system. like aem ems/hptuners/megasquirt/custom power commander. the inconstant fuel needs from idle to powerband of a 2 stroke are very hard to overcome on a forced induction system.
3. the way a 2 stroke exhaust scavenges, the turbo will constantly see different turbine speeds even at idle. thus eating the bearings and seals after time.
4. your going to blow the crank seals of a stock blaster like britney spears hymen when timberlake got ahold of that. all that pressure will eat those seals fast, then your doing nothing but pressurizing the tranny.
5. unless your recirculating the boost lost when shifting. the lag of pressure, then sudden power of the turbo hitting while the motor is already in powerband. will almost rip you off the bike so you have to recirculate to have even shifts.

Try not to be so discouraging guys. If everytime someone decided to try something different and they listened to the people who said "that's not possible", nothing new would ever get done...
Borednstretched hit the nail on the head about the size of your turbocharger. That's too large a fan buddy.... it'll never build any boost on the volume that the blaster flows.
However, turbocharged 2 strokes are not impossible or all that new. There are several videos out there of turbocharged 2 stroke snowmobiles. Unfortunately, they are complicated and expensive to setup (pretty much like boosting anything) and most ATV's aren't setup for turbochargers.
There are a few problems I see with turbocharging a blaster. Fix these and you've got a shot at it
1) Mounting the turbo and building a pipe. It needs to go at the end of a specially built expansion chamber (tuned exhaust) because of the increase in pressure (back pressure), the change in temperature makes a normal expansion chamber not as efficient as it is on a N/A engine.
2) if you're running a flooded bearing or ball bearing center cartridge, you need a constant supply of relatively high pressure motor oil (pumping the transmission fluid around the turbocharger COULD work but you'd still need the pump. I think that a dual gear oil pump COULD be fabbed to fit where the stock oil injection pump is. HOWEVER, you are stuck with the delrin plastic drive gear for the stock oil injection pump.... the output from the oil pump NEEDS a low pressure "hobb's switch" hooked into the main relay for the fuel pump (we'll get to that later) so that if the oil pressure falls below, say 5 lbs, the fuel pump shuts off so the turbo won't become shrapnel falling out of the silencer
The other option is an "aerocharger" which is a turbocharger which is VERY specially adapted to work without a constant high pressure motor oil supply. They are quite expensive and only available directly from the company: AEROCHARGER Turbocharger is the most advanced form of forced induction, giving you the edge over the competition. First to Boost, First to Win.
3) blow through and suck through carburetors have many deficiencies. Part of the advantage of a carburetor is how simple they are. When you boost one, you take away that advantage and invert it, they're more complicated than they're worth.... 2strokes require a very tight fuel control to maintain AFR and there is NO room for error. A carb'd turbo'd 2 stroke could change 200 feet in elevation and be woefully out of tune!
4)EFI.... there are a few options which don't require $4,000 but they do require a working knowledge of fuel/air, ignition. and ignition timing theories. If you've never tuned any fuel injection system yourself, you'll REALLY be diving into the deep end of the pool with an EFI forced induction air cooled 2 stroke. This system:
Small Engine Fuel Injection Kits for Turbo Charger applications - Small Engine EFI Conversion Kit | Small Turbo chargers
Is about the most economical EFI system with relatively low power demands that is specifically setup to handle boost.
5) power! you're going to NEED to do a DC conversion on your blaster (to get 12VDC out of the lighting system to power the EFI system) and upgrade the lighting coil to produce enough power to run the system. The EFI system has a power draw of about 4amps, which is about 50 watts. The highest commercially available replacement stator puts out about 75watts and you can't expect the AC to DC conversion to be perfectly efficient....
I agree. Not even worth trying. I seen one turbo project started on here that just faded away do to not working out. Even if you could get all worked out and working good,it wouldn't be worth it. You would still have less power then a built Banshee.
