i cant see how the hell to get to the wastegate to install this thing... no room from underneath, and from the top it seems i would have to remove my AC compressor and maybe some other stuff...

anyone know any tricks? or am i missing something?

you don't ahve to access the wastegate actuator, just the hose taht leads to it, not sure where it hooks on a stock system, but on some of the older cars they referenced boost right at the turbo, you can plug that line and run a new reference line up to one of the ports coming form your manifold, and "T" ti in for easier access, and if you take the air inlet pipe off the TB to the turbo,a nd the heat shields by the brake booster you can get to everything pretty well

lol, it's all good, glad you got it in, careful with the boost,10 psi with no intercooler will generate intake temps of over 200 degrees! this kind fo heat can lead to preignition, which makes pistons melt, and ring lands break, I highly recomend adding an intercooler

thanks for the concern.. i'm lucky enough to have 93 octane gas around if needed. i dont sustain those levels of boost for very long, but im taking precautions to prevent detonation, and intercooler work is in progress
