Hahn Turbo Installed folks (2.4s) -

Putting on the Hahn Turbo Kit and having a bit of problem where the pipe leaving the intercooler connects to the pipe going into the throttle body.

In a nutshell, the pipe coming out of the intercooler seems too short. Anybody else encounter that, and how'd you work around?

In detail, the piece running out of the intercooler, I'm assuming SHOULD, (with its little bracket facing toward the passenger side) mount to the frame with the supplied rubber bushing on top of a bolt just behind the radiator.

Then it runs should straight up, behind the radiator hose, and use the 2" to 3" silicone convertor piece to link into the piping that runs straight across the front of the engine, HAHN side up, into the throttle body.

The problem I'm encountering is that there seems to be about an extra inch or two of space between the two pieces of pipe, at that 2" to 3" area. Even though the converter piece is "bubbled", it's just a bit short.

Workarounds we've considered (i.e, we can let the pieces actually connect, without cutting a new piece of pipe):
- Using a slightly longer 2" to 3" convertor piece - obviously this is not optimal because it's more "air" between the piping.
- Mounting the piece coming out of the intercooler "upside down". This creates a problem because the intercooler pipe now runs between the radiator and its coolant line, which may cause heat problems, and causes the throttle body piece to be canted at an odd angle.
- "Forcing" all pieces, leaving the intercooler piece unmounted and placing throttle body piece at a really weird angle.

If someone else HASN'T had this problem, and can take a photo or two of how the pipe coming out of the intercooler is mounted, and how it links to the pipe going into the throttle body, I'd be in you debt.


In other news, for those who were interested, I went ahead and decided to keep the kit - and I'm installing now. Started Monday evening and been working on it a couple of hours a night through this week. Thanks for all the interest when I was thnking about selling it, and for those of you on the edge - according to my mechanic friend helping with the install - it's a very well put together kit. Aside from this one minor hiccup - everything's been a breeze.

 

its very easy to swap the charge piping parts.

My suggestion is this.


Do your intake..then the tube from the TC to what would be the Intercooler entrance.


Try switching your I/C piping from each side.

i did not have a "short" piece. and im sure its something you might be overlooking.

if all else fails, did you use the wrong coupler somewhere? when i get off of work @ 5 (about to leave in...well..after i post this (9am), and if you didnt fix it, i'll take some pics for you.


good luck to you though. once its done, you'll be grinning ear to ear.

 

I'm not sure if I can switch them over or not. The piece I'm having a problem with is the 2nd from the intercooler in this photo of the Garrett 2.2 kit.

That's the piece that should be coming out the driver's side of the intercooler, right?

 

Take a look at the top left photo on page 77 of the August GM High-Tech Performance and you can see how it got routed on my car (keep in mind that as it says in the caption, I had to make some minor adjustments afterward - but you can at least see the approximate placement of the pipe). Just off the top of my head: see if you can get it to work WITHOUT attaching that pipe's bracket to anything. Maybe you are trying to go the the wrong place, or maybe on your particular car you'd be better off just leaving it off.

Also, the pipe leading to the throttle body *will* be at a slight downward angle, sloping down toward the driver side of the car. Hope this helps.

Thanks Chris.. that magazine is available anywhere online is it?

Can you confirm that it DOES NOT mount to anything (the bracket). The concern we're having is that way it rubs against the radiator hose a bit - this hasn't caused any problems?

 

I had issues with the brackets as well. They didnt hold onto anything...so i just took my dremel to them and cut them off.


I think the one you said is on the passenger side.

 

The one on the passenger side is the one right next to the intercooler (with the BOV line). I'm talking to the one just to its left.

Anyhow, i guess the basic question I have is, the piece you have on the driver's side running out of the intercooler - does it run "back" more or "up" more. It can run two ways, basically straight vertical out of the intercooler after its 90 bend, or it can run back behind the radiator line and come up just about dead even with the PCM. If you run it "up" more, meaning the short end connects to the intercooler, it's long enough but you need a 45 piece of silicone tube to connect it to the throttle body piece.. if you run it the other way ("back" more) you need a tube that's about twice as long as the one they give.

Basically if you could give me a measurement from the tip of your radiator to where the two pipes link, that'd help a ton. If you could take a picture of that connection, and where it is relative to your PCM, I'd buy you a cheeseburger.

 

Kit fit like a glove on my car.

 

Mine all fit great.





I didn't even have to take the front bumper off!

 

Show off!

 

I read the directions.... said F*ck that!
I got my hands up in there and got the bolts on witout touching the bumper!

 

Well, hey, we got it. We ended up flipping the radiator hose around and everything worked perfectly. I'm assuming it's probably someting that got fucked up when they replaced my transmission.

By the way, of note - the kit 'sits' differently in the 2.2 than in the 2.4. Great examples above actually. In the 2.2, the throttle body pipe goes straight across in front of the engine pay, in the 2.4 it cants forward toward the radiator a bit. Reason why is because this piece (the one coming out of the intercooler) is inverted to work on the 2.4.

Reason why THAT is that the 2.4's throttle body sits about 2 inches higher than the 2.2's.

Anyhow, on to the fuel tank . Thanks for the help.

 

Guess, you don't need this anymore, but just in case:

The bracket on the driver side pipe does not mount to anything. On my car, it didn't even have to be removed - just juts toward the driver side just above the two steel lines (which I believe are for the trans cooler - mine's an auto). It does rest on the curve in the radiator hose, and seems pretty secure nonetheless, though can be pulled up and down an inch or so if you try.

Hahn has the articles posed on his site:

Glad to hear it worked out for you.

 

Yep, we got it. All buttoned up and just waiting on the PCM now.

By the way, you may want to consider flipping your hose around like I did. It really moves it out of the way and of course does away with any chance of rubbing, and also opens up the opportunity to use an L Bracket to affix the pipe bracket to just behind the grille if you were inclined - there are even a couple of holes already in place.

 

Thanks man, will keep that in mind. Looking forward to your results!

Chris

 

glad to see you kept the kit.

 

Well hell...

since everybody else is postin pics of theire kit...i might as well do the same.



And didnt you have some shop do the work for you?

 

^No, I just had a friend that is a mechanic helping out.

It was just working counter-intuitively. Everything else went on so easy and this pipe just wouldn't go.. you know how it is.

 

The shop comment wasnt directed at you.

Was directed for Mkurley.
