I hate to tell you mate, if theres oil on your comp wheel, its time for a rebuild! I always wondered why turbo manufacturers used pistons rings to keep the oil from leaking onto the Turbine/Compressor wheels...
So tell me, I buy a 180sx standard turbo....my "wheel" is lubricated....where does the oil go then? Into my intercooler piping? Into my throttle body?...or does the oil get "sucked" back through the turbo? I might be better off driving a magic carpet non turbo?
You might also want to keep in mind, that you would usually tap the block for oil supply, and if theres enough pressure to push oil from the sump to the Turbo, then i'd be pretty inclined to do a compression test....or in your case, its a Honda, so burn the thing and push it off a high cliff.
As much as arguing with lrdbsi would be pure enjoyment, i'm gonna have to disagree here. Depending on what Supercharger you use, you'd expect to get at VERY LEAST a 20% increase in power over standard, its forced induction . Seeing this thread though, I think lrdbsi would go with this type: http://cgi.ebay.com.au/Electri ... ZWDVWQQrdZ1QQcmdZViewItem
Actually mate, you'll find an RB20DET can run 12/13psi comfortably without fuel system mods. The ceramic turbine wheel falls off when running 14psi upwards
