First of all, when I bought the car, it came with a 88 (s4) "shortblock" (block/rotors/omp) and everything else was S5 (accessories/intake). I think only the LIM was S4 so it could mate with the S5 intake easily.

Well, I couldn't quite figure out why my 6 ports always looked different than other S5s.

I'm pretty sure that the 6ports on my car now are S4.

The previous owner told me that the 6 ports were T'ed into the airpump. IIRC, the 6 ports on the S4 are EXAUST operated. I have not taken anything off my engine past the throttle body, or just the actual 6 port actuators.

My question is, what parts am I looking at here. I'm not sure if the ACV is S4 or S5, or the intake manifold is S4 or S5.

Here's some pics.

The car doesn't have registration or a plate on it, as well as a battery... so I have no way of even TESTING the 6 ports. They are very free to move manually, but not sure if the exaust back pressure is opening them or not.


The parts that are laying in the chair are parts that came with the car in a box. Don't know what's what.. I've checked the FSM, but can not tell the difference between ACV's and the 'intake manifold.'




ACV


Intake Manifold Side


S5(???) Intake manifold with ACV and actuators on.


Same Thing again...


Bad pic of the intake manifold, with the s4 actuator off the car.


This is the S4 actuator correct? Does not have a 90 degree air pipe coming out the bottom, only a screw.


Same... S4??


S5?


S5 again?

I can't get a good pic of the intake manifold ON the car, but just wondering how to tell if it is infact being operated by exaust... or by the airpump (if that's possible)

If you need anything clarified, or what not.. please lemme know. Want to have this puppy running PERFECT by June.

 

The 2/3 pics are of the S5 LIM, correct. The LIM is specific to the entire manifold assembly, so it should either have one of the other intake assembly.

I've done some mixing of manifolds in the past few days (attempts) and it doesn't work.

Feel free to PM me if you have questions about some of those other intake pieces.

 

Bottom line, like I told you a long time ago, the only way to make that thing right is to put all the right parts on it. Mixing and matching **** doesnt work out in the long run.

Just buy all the right stuff, bolt it on, and be done with it. Why is this so hard, in your mind? IT could cost a maximum of a couple hundred bucks for all the s5 intake, vacuum rack, and other components.

 

i had a blown actuator (s5) and picked one up in the used parts forum for $5.00+shipping. They aren't expensive if you find someone willing to part them.

 

First of all, this is how the car was when I bought it. I haven't taken any of this **** apart because I don't need to. I knew it wouldn't be long before curiousity got the best of me and I started taking **** apart.

AFAIK, since my block is a S4... I could only use the S4 LIM. (Or I could use the S5... but it would require modification)

Yeah, replacing the LIM WOULD yield better gains... but it will still run at the moment right? Ok then.

It's not so hard in my mind Kevin. I would rather dump that S4 block and get a S5 and ship that ****** to you to get rebuilt... believe me. I just don't have that money yet.

I have the S5 LIM, and the actuators.. but the manifold I have is COVERED in carbon, and the actuator connectors and rods are both missing in the manifold (they were broken, so I popped them out)

Thanks for the help guys, got my answers.. all I needed

Kevin, sorry if I'm "annoying" you or what not. Not my intention... just wanted some clarification that I couldn't get from the FSM.

I dont know of any modification that'd be required, to be honest. If you put an s4 intake on an s5 block, you'll have a port air/egr leak that has to be plugged up. This way, the only issue is that the s4 block has no such port air hole, and it may not pass emissions that way, even with the use of the vacuum rack and associated hardware.

Not really, they flow the same.

Why not just leave it alone until such time that you do then?

Well, you know, being around this on a daily basis and listening to all the swap-happy-talk gets on your nerves from time to time. These cars are really simple if you use the right parts, and really complex if you mix and match. Yet, everybody seems intent to mix and match parts, just to say that they did. And then, they want to turn right around and complain about the issues their car has, and want me/us to tell them how to fix it. I get calls like this all day long, from people I have never been associated with, sold anything to, or did any work for. THey expect me to sit there and get them out of their mess, that was created ONLY because they chose to do some kind of part/engine swap that was unnecessary.

I don't mind helping people, don't get me wrong. I just dont see why it is such a hard concept that if you want your car to work right, you bolt in the parts it was meant to come with, turn the key, and you're done (provided you did the work right).

 

Keep it friendly please. If the hostility is because of a previous PM conversation, then keep it private.

 

uhm...okay?

 

Don't know where that came from..

anywhow.

THe only reason I posted this message is because the S5 FSM and the S4 FSM are the EXACT same as far as the port actuators. I just needed some clarification.

Didn't want to know which parts I could swap...

-Jon

 

As a matter of fact.. im looking at the S5 FSM right now, and it shows that the actuators are always in the extended postion.... WTF!

Think I'm going to go buy a Haynes....

 

The actuators on s4 cars pull to open ports, the s5's push. IIRC, that is.
