aux ports on a 91 na question
 

ok so when i got the car is wasnt running due to blown oil cooling line. i have since fixed that and it runs good and all but it seems that the aux ports are not opening. my 88 na i previously had seemed faster/more power.. the car has some type of after market exhaust.. the power steering pump, ac, and air pump are not hooked up.. power steering leaks.. pump was missing hoses and ac because it was idleing funny like really low idle like it would almost die.. how do i fix the ports with out the air pump? thanks alot

You don't.
Generally you can NOT activate the S5 5th/6th ports without some sort of airpump.

Just put it on, its weight is meaningless and it's parasitic drag is equally meaningless.
Also, you loose VDI by not having it... [Half of the improvement of the S5 engine....]

If you don't have a stock one, most people would sell one for $10-20 or just give it away...

Without 5th/6th and VDI, it most certainly WILL be slower than your S4 was...

well i have my pump still just no hoses.. my problem i guess is not knowing how to plumb it

Normally the path is: Airbox -> Pump -> ACV ->[internally] LIM -> Rats nest ->Solenoid [the two above the rest are VDI/Aux ports] -> rats nest -> nipples [on S4 the aux port nipple is near the lower left of the LIM, VDI should be right on the actuator on the driver's side below the dynamic chamber]

I believe there's a colored S5 NA vacuum diagram floating around, should be able to search and find it pretty easy. ^_^
