I have a 2002 24V. I pulled the intake off the turbo the other day to take out the silencer ring and noticed some impeller fan damage. I took my truck in to the dealer and they inspected the turbo and told me that Dodge would not cover the turbo under warranty since it appeared something had been sucked into the turbo. I believe this damage happened before I bought the truck, because I think I would have noticed something bouncing around in my turbo. Anyhow, I was wondering if anyone has any suggestions, should I try to fix the turbo(if economically feasible), replace the turbo, or if someone has another suggestion. The dealer tells me that the turbo is still woeking properly but I am hesistant to believe that. Any information would be greatly appreciated and thank you for your time.

 

Look what I am asking is should I rebuild or replace. Is it economically feasible to rebuild or should I just go for a better aftermarket turbo? Is it possible to simply replace the impeller or is it more complicated than that?

 

EEEEEEbay.

 

If you are going to mod the truck start looking for a better turbo. If not may be easyer to just replace with one from ebay or you local wrecker. If you can post a pic of the damage. If you are realy woried about it dress out the damge if possible and that should work to prolonge the turbos life intill you decide what you are going to do. Just my two cents.

 

is the damage causing you any problems?? low boost?

 

Not that I can tell I haven't put in gauges yet that is on my list of things to do. So I can not tell how many pounds of boost I am running.

 

If I were too upgrade the turbo I have looked at Jannetty racing and they have a 12cm2 turbo for sale but I have seen some of the members here talking about 16cm2 housings is this the HX35 with a larger housing or is it another turbo all together. Based on my signature do I have the ability to run a larger turbo and if not what things do I need to upgrade in conjunction with a larger turbo to be able to run higher HP? I want to start upgrading my HP what is my next step from where I am now?

 

HX35 with 12cm2 is a stock turbo on 5/6 speeds and some autos depending on the year of the truck. A 16cm won't spool fast until you get some more fuel. You can get a Hx35/12 for around $200-300 used.

 

A 16cm turbo is just a slightly larger displacement exhaust turbine housing on a HX35......it has nothing to do with the compressor side of the turbo.....so getting the larger housing won't help fix damaged compressor wheel blades. A 16cm housing HX35 requires much more fueling over stock to keep the lag to a minimum. I would not suggest it unless you were operating the truck on just the highway.....around town and at slower speeds, the lag will be annoying. Once you add a lot more fueling, consider the larger turbine housing.

 

You can rebuild them, the kit is about $90 from High tech turbo. The build is very detailed but not hard. You can down load instructions from Holeset.com. READ the whole manual before you decide. You can also get a new compressor wheel for about $70. I will post more tips if you want.

 

I will answer your pm here billygoat02. The first thing to do is to go to Holeset.com and download the rebuild manual and torque specs for your turbo. You will need the info off the tag on the compressor housing. After you read every blessed word of that manual and you understand every blessed sentence you are ready to buy parts. Call High Tech Turbo in Salt Lake City Ut or email them, here is the addy www.htturbo.com.
You will need a rebuild kit, a mounting gasket, and a new compressor wheel. The total bill should be under $200. When you contact them you can ask them any questions you want, they are good to deal with. When you parts come in the mail, you gather up some cleaning solvent and the tools you will need. You will need an inch/pound wrench, snap ring pliers, big channel locks or big snap ring pliers(harbor freight has a set for about $15 that make the job much easier), a vise, and assorted metric sockes and wenches. A crow's foot wrench will make torquing some of the center section bolts way easier, I don't remember the size but 14mm jumps into my head. Remove the turbo from the truck, soaking the exhaust bolts in pb blaster or wd40 for a while will help alot. When the turbo is on the bench, begin the dissasembly. MAKE NOTES ON HOW YOUR TURBO GOES TOGETHER, THE MANUAL IS GENERIC AND INCLUDES SOME PARTS THAT DON'T GO ON EVERY MODEL. Note every part and piece as you take them apart per the manual's instructions. If you get lost don't guess, call high tech turbo and ask questions. Once the turbo is apart you need to inspect the center section for coking. Coke is an extreamly hard deposit that is made when oil cooks in a hot turbo. We idle down the egt temp to avoid coking. I idle down to about 350 to 400 and I didn't have one spec of coke in my center section. You might be able to scrape the coke out if you have some in there. You might also media blast the housing clean. If you have a small amount of coke and it doesn't block any oil passages you might be ok to leave it. Inspect all the housings with a magnifying glass for cracks. With the housings clean and inspected NOW YOU MAY OPEN THE REBUILD KIT. You are now sure that you don't need to get a whole turbo. Upon reassembly, refer to your notes and the manual. One thing that I ran into is that the snap rings that hold the bearings in the center section are chamfered and only go in one way. I had to use a magnifying glass to see the chamfer. When you are ready to install the compressor housing you may need to dress it with a file to smooth out any contact damage, light filing won't hurt it but don't go crazy. Here is the kicker, on some models there is a rubber seal that seals the compressor housing to the center section. I didn't keep notes on how my turbo went together so I put the seal in. The housing didn't seem to seat well but it made sense to have the seal there. I went up El Cajon pass at 85 and the compressor housing blew off and totally trashed the compressor wheel. Lucky for me the damage was minor but I still had to do it over. All in all the job is not that hard, you just have to be detailed.

 

Sounds like all he needs is the impeller.
