Anyone have any knowlege on turboing 2 strokes?

[GREASEMONKEY]

Just seeing if anyone had any previous experience / tips..

Here is what im working with.

91 Ski Doo Plus X 583, Its mostly all stock except for the C&A Ski's, And the intake manifold i just made for it. The main question i have right now is how do you get oil pressure to the turbo? I was thinking about using a 12v universal pump from Orielys but i dont know if that will provide me with a consistant oil pressure or even have enough pressure for the journal bearings.

I was thinking about using a 12B turbo and hopefully that would be small enough to spool at a decent RPM.. (If anybody has one, or something simular shoot me a PM)

Also do the carbs need to be set up for blow through? I belive i was reading something about this a while back but don't remember too much about it, Im only trying to run about 5psi if i can, Hopefully the motor is strong enough..:biggrin:

Also if you have any of these parts shoot me a PM with a price and a number id like to gather these up before the weekend.

I need..

*12B Turbo or something simular
*Cheap MBC
*Stock DSM Bov


Thanks

There is a shit load to turboing a sled then what you think. I am in the process of doing it myself and will be posting up my kit and process once finished.

You have to convert the carbs to blow thru, run a different fuel setup to supply about 5 psi of fuel pressure over what boost you are going to run, change timing, lower compression and much more. You cant use a small turbo that spools quickly because the exhaust pressure will be to high and will create too high of exhaust temps. Let me know if you need any help. I have been in contact with a few people in Utah and Canada with my setup and should have all the parts shortly. I am going to be running a 14b and 4-6 psi and about 10 with e-85 and should hit over 200hp with a 600cc 2 stroke motor.
