1989 GTUs

i got a dual atl. pulley (not installed yet) but i read this in another forum

"Be aware that if you have a 89+ NA, the airpump also actuates the 5th and 6th port valves, as well as the VDI so you will have to figure out how to make them work."

i have a 89 GTUs so this got me thinking how would i fix this problem..how will i get the air pump to start working? pls help
thanks

By leaving the air pump on..ie don't change too dual alt pully.

You could get away by using a rpm switch with a small electric air pump too open the ports, try searching might find something usefull.

You don't have a problem to fix. Leave everything exactly as it is. By leaving the air pump in place you'll ensure the 6PI and VDI systems work correctly. The dual-belt alternator pulley is only required if you remove the air pump, so unfortunately you've wasted your money there.

get rid of that air pump man. then remove those stupid 5th 6th port actuaters and open the ports and hold them in place with some metal wire.

Yea, for S4s. (Even then, they save you the greens)
For S5's, it is actually needed for proper function.

Since you don't know what you're talking about, I suggest you stop posting.

my car is an n/a

a) i dont have my secondary cat, so i do not need air pump for this.

b) i dont try to race my car below 4000 rpm, and do not drive my car on the street, so i am not concerned with low end power or fuel consumption.

c) the air pump sucks down power, adds weight, and complicates the engine bay.

In case you missed it, the person who asked the question, and hence the person the answers were directed to, has a S5, so your car and how you use it is irrelevant and most of your advice is wrong.

oh hey... heh i sent this guy a long pm about it... he never responded, i dunno

An electric air pump seems pretty pointless when you already have a perfectly functional mechanical one that'll draw about the same amount of power from the engine as an electric one.
