s4 s5 turbos
 

Q: What is the visual difference of a s4 turbo?
S5 Turbo? How would you tell them appart?

Thanks,:allcho: :allcho:

The 2 exhaust ports on the s5 turbine side are of the same size .. on the s4 they are of diffrent sizes..

Differences you can tell with it on the car?
thats what i wanna know.
I'm not sure which one is on my car. I know which one is factory on it, but not which it has on it.

Thanks,

Take a look at your wastegate actuator then..

If the actuator bar is straight, it's a series 4 .. if the actuator bar has a bend in it, it's a series 5

what about the little tube that runs around the housing to the waste gate, i know there is supposed to be something different there.

somebody knowledegeable. Please help

Sheesh.. silly me.. I guess I just don't know what I'm talking about then...

Compressor housings between the s4 and s5 turbos are the same..

The s5 turbo when it was installed in an s5 car had an extra solenoid to control boost.. the s4 does not have this.. so even in you had an s5 turbo in your damn car you wouldn't be able to tell from the wastegate line..

the s4 turbo would have 4 acutators on it.. one for the wastegate (which as mentioned before, has a straight bar) and the Twin scroll actuator..
The S5 turbo does not have the twin scroll actuator below it...

But wait.. oh yeah.. I forgot.. I don't know what I'm talking about.. sheesh

Gee, Chris Ng knows his stuff - it was your question that is vague.

You're talking exterior body?
All Zenki model have a black rubber "rub strip" in the middle all the way around the car.&nbsp The Kouki model were all color keyed, and that strip is a little wider.

The mirrors are different.

The front bumper is different; the rear bumper is different.

The Kouki model had side skirts that give it slightly different shape.

1987 turbo has "10-fin" rims - 1988 turbo has 7-fin rims - the Kouki turbos (as well as the GTUs) had 16"x7" mesh rims.

Your a dick, You were signed off and i have to find the answer to the damn question. But hey thanks alot.:flipoff: :eatme: :asshole: :bgfuk: :moon:

not you ted,

And no, im talking aobut the turbo itself. not the car

Chris Ng can be quite harsh for some reason, but he does know about these things... but why aren't you listening???
What else do you want to know?!?! It looks to me like your question has been answered- it's not like it has S4 or S5 stamped into the housing!!

I'm not saying anything else. I've resolved to keep my opinions to myself.

thanks for doing that, and that was all i did need.
I did thank him.

Excuse me?
You ask for the diffrence betwwen turbos, and I explain an easy way of identifying them...
You come back and say it's installed in the car.. so I give you another method of identifying it while it's installed.. easy enough for a trained monkey to figure it out...
You still couldn't figure out how to identify it .. so I give you yet another method....
and now I'm a dick?

It's no wonder nobody else has bothered trying to reply to your question.. asshole

no, thats not it, i could figure it out your a dick because of the fucking way you responded, when i said anybody knowledgeable, because you were signed off, and i was having to make a decision right then, that would cost me some cash and i needed to know the answer, Thanks again for helping me. But you don't have to be a cock about it.

Smirk.. I think it's just that I'm turning into an old crusty man :) But really.. I'm not all that hostile.. I know we've had our diffrences in the past Bam, but at least to me, it's kept things intresting for me on the fourms..

As for this situation, I don't belive I started off being harsh at all..

shrug.

Yea, i don't think you started off this way, but you sure got there pretty fast:ak47:

When upgrading from an S4 turbo to an S5 turbo on my 87 TII, do any other changes, aside from the manifold, need to be made?? I'm going to be breaking my engine in for 1500 miles and don't intend to boost during that period and before I do give her some gas I intend to have a boost controller on there.. anything else??

Thanks

Naw, it's just that some people need very little provocation before they get all offensive. (read above!) Some people are easier to rub the wrong way than others, like this yahoo, and if you are a little harsh or blunt, some people will fly off at that, and start getting personal!

Anyways- like I said- you know your stuff, it just may not come out sugarcoated! :)

Hey... I though I just said I was keeping my opinions to myself a few posts ago.... damn procrastination!
Cheers.

its cool with me, just pissed me off at the time.

With a reply like this, you're lucky not to get a warning. You got all the info you needed (politely), then fired this back. If you needed an answer quicky you should have said so. Your question was also missing the fact that the turbo was on the car. We're not mind readers, and no one likes being insulted for trying to help. Try keeping it civil, or nobody's going to bother answering you.

hey, i didn't ask you to read my mind.
I'm sorry i diddn't say it 100% correctly.
I was very busy,

And no i diddn't get it all politely,
I got it while he was bitching b/c he thought that i said he didn't know anything.

Simple.

If im right...

Look where the manifold meets the turbo.

If its a S4, it will be close to 45 degree angle.
If its a S5, it will almost verticle.

The easiest way to tell is to look for (the absence of) the twin-scoll actuator.&nbsp This actuator is pretty big - almost the size of a soda can in front and slightly lower than the turbo (compressor) itself.&nbsp The Kouki does not have the twin-scroll on it.&nbsp Chris Ng also pointed out the fact that the Kouki turbo actuator is BENT, versus the Zenki turbo.

The Kouki and Zenki thing is going to seriously mess him up. It messes with me :)

Ha ha ha

That was funny. The problem is Chris doesnt have a big enough post count. It seems no matter how much you know it's hard to get any respect around here without a huge post count.

Just cause you have a big post count doesnt mean you know anything, look at me I'm over a grand and I know fuck all:)

Remember, size don't matter.. it's how you use it :)

But hell Graham, you've come a long way since last summer.. did you actually thinnk that you would ever pull your own upper intake off or do your own turbo swap??

Mind you, I got alot of help from alot of people in the past to get me to my current familiarity with the car..

I do have to give a big thanks to Ted.. When I got my first T2 he always had the time and patience to listen to my ramblings, questions and whining on irc.. He always gave me great advice and best of all he never made me afraid to work on my own motor, which is one of the best traits in getting to know the cars.. if you arn't afraid of trying things and potentially fucking things up, you'll always learn what works, and what doesn't...

I've had some disagreements with Hailers and Irv in the past as well, but their knowledge has also cleared up a few grey areas for me..There have been others as well.. BlueTII, copanengr, etc .. The trick is to find out who knows what they are talking about, and who is mearly guessing....

Oh yeah.. Max, I can't forget him either :) He's like mcgyver to me.. always has a fix or workaround when things get hairy.. Without having him around things would definitly progress slower :)

I appologise, for the way it might have come off of what i said about anybody knowledgeabel. but you had signed off, I wanted to keep the post at the top b/c i was in a hurry and needed to know for sure. And ted was signed off to and i didn't know who else would. No my thread count is not that hi, but its getting there by trying stuff, Screwing it up. learning the right way and give the info on the way i did it. The same as everyone else on here. Half the stuff i have done to my car would not b possible with out the help of the forum, and some local Pensacola guys, Who are the greatest help to me.

Thanks again chris, and everyone else who has helped another,

I get hassled all the time by the local guy's cause when I first bought the car I swore to them I was going to leave it stock, since then it's seen it's fair share of modifications. Most of which would never have occured had I not found info and help with the local guys and members of this forum. You learn pretty quick who knows what they're talking about on here. I think the key is to just jump in and give it a try. There is always more than one right way to do something, you have to learn for yourslef what works best. My fat arms have me finding different ways of getting at stuff that the skiny guys (Chris, Max) have no problem with.
