Hey guys whats up, I've been reading this forum looking at how to make my lil xr2 even faster. While reading I saw a pic one of you guys had of an engine compartment. The thing that has me confused is the line running off the front right of the main intake tube on top of the valve cover. Mine is just capped off!!! Wondering what was and needs to be connected there!? Any help is appreciated, thanks.

He's referring to the PCV system. That hose might actually hinder performance slightly, since at boost it tends to draw some oil into the intake line. It's recommended that hose be routed to the intake, or to some sort of breather setup to pull in air to keep the crankcase pressure down.

Unless you mean ABOVE the valve cover, that hose runs to the Wastegate diaphragm on the turbocharger, slightly under the exhaust manifold. They may have rerouted that for a boost controller setup.

Thanks rcdraco, yea thats what it was for and it was rerouted for a mbc. Thats what I figured it was, but I wanted to be sure as I am reintalling the motor from a complete overhaul. It would suck if I was leaving something unplugged and I'd ruin the motor right after fixing it.
