On my 85 SE I'm in the process of installing the Pineapple racing 5th and 6th port sleeves and because I have to take off so much of the intake system, why not do some upgrades? At the moment, I've got the entire throttle body, Upper intake manifold, ACV (I've got a block off plate coming), and the port actuators all off. The air pump and air box assembly are off as well. I'll post a picture later when I can.

But my question is:
1. What can I do to my throttle body to make it better or should I swap in a newer one from the s4 or s5?
2. For the intake, should I go with an intake from the s4? (I don't know if the s5 fits?)

Thanks.

I have a stock SE as well. I'd be interested in your results if you do an S4 or S5 intake swap. From what little I know, the s5 fits better, but neither swap is a simple bolt on. You have to do some mods to get either one to work. Please keep us updated with your progress!

Also, to get the lower intake manifold off, I have to get the bolt on the farthest to the left and bottom. This is very difficult because I have a racing beat header installed and the way the tube is shaped, the top of it blocks nearly all access the bolt. Has anyone encountered this before?

S4 should be a direct fit. S5 requires rewiring and the use of an RPM switch to actuate the VDEI. Also, you must use the s3 or s4. 5-6 ports as s5 are electronic. Are the primary injectors in the intake or engine on the SE?

WalkerCaroll

So would I need a S4 lower intake as well as the upper intake? Because I've got both of them off the car at the moment. I don't know what the primary injectors are but there are some sort of injectors on the middle two holes at the top of the lower intake.

Another question:

Now that I've got the bolts off the lower intake manifold, how do I go about disconnecting all the different lines? Some look like they have fluids in the them and some require a wrench to get off. If you could link me to something or explain it to me here that would be great because I cant seem to find it in the FSM

umm, contention

s5 aux ports are pneumatically driven by the air pump , and the air pump itself is electronically switched and electronically directed ( via a pneumatically controlled valve )

using them on an s4 or GSL-SE engine begs the questions of both electronic control and a suitable pneumatic source

to the OP.. you have header pipes .. this alone has changed the switch-point for your aux valves later ( when exhaust backpressure is above 1.8 psi )

i would go as far to say that the best thing you could do would maybe have a look at method to utelise the airpump to drive the aux valves , using an adjustable home kit rpm switch and an ex LPG shutoff solenoid

1. I have the air pump removed already (EDIT: and I still plan on keeping it off). 2. the auxiliary ports should be working because of the way the pre silencer is set up to direct some gasses back. 3. If the S4 intake bolts directly on and keeps the same way of activating the ports, why should I bother with the S5? I've got an ACV block off plate being shipped to me right now and I've got intake manifold gaskets arriving tomorrow for whenever I decide to re install this thing back together.

But how should I go about disconnecting all the little hoses and junk that are connected to the LIM? It seems like I could really screw this up if I do it wrong.

But, the air pump air injected to actuate them is controlled via solenoid right? Thats why i say theyre electronic. Its been too long since ive had an s5...

WalkerCaroll

On the S5, the actuators are run off the airpump. On the S4 they are run off exhaust gasses and thats what I want to do. So If I buy a S4 complete intake system, will that work with my car and get the ports open when I need them to? I've got two people that are willing to sell me those parts right now.

and as such ,, because of your modified exhaust system,, they will come in later than designed

you want an improvement .. and you want it cheap? then put the air pump on.. hook up a control solenoid .. fit an rpm controlled switch ,, and actually have your aux ports working at a point which YOU choose .. and not far too late when the exhaust backpressure eventually gets up to stock levels

1.8 psi,, does not matter if it is exhaust or airpump.. will drive the s3, the s4 or the s5 solenoids open

WalkerCaroll

So would a S5 intake be a good setup to get or should I just stick with the intake I've got? And how hard would it be to do what you just suggested? Because I'm no good with this kind of stuff so I don't know what I'm doing. Im really relying on instruction.
