ETEC Turbos! The feed back from our turbo consumers is still having to run too much race fuel to keep off the detonation, and spark plugs breaking. The stock head is NOT designed for turbo applications. So we have turbo heads availible.

PISTONS- Dont let anyone tell you the 85mm 860 piston is not reliable and cracks or breaks off the skirts. Thats a lie. We use the best Japanese pistons availible in the world. With proper silicone content and proper piston clearance it will last 5000 miles no problem. We had some put on 3300 miles in one season. Some shops are using a different 85mm piston or a off shore made piston with improper silicone ratings, poor rings and have the piston clearance set up wrong. So then any piston would crack. Just a gimmick to make you buy there kits. Would you rather have a 872 kit with an off shore piston? not me.

No hp gain with .5mm bigger piston, weaker cylinder skirts, an offshore piston and little porting.

600 Stock Etec head machining modification.

Gain HP all thru the RPM range for high elevation riding.

Thermostat kits for Skidoo XP's and XM's. Will work on other models as well.  These are the real deal. Thermostat starts to open at 90'f and closes off the bypass at 120'f (not155'f) so your engine will run cooler and  make max hp. If its running over 140'f its starting to loose hp.

$299 cdn.
