Holset Turbos, PART 5

[Steve93Talon]

Shep used to run a one piece CF driveshaft, bigtime vibration issues. I believe he now runs the DSS aluminum one.

I wish there was a way to get actual information from Holset part numbers.

It looks like the H1E is the same as the 8-blade HX40 but it has a 3" (?) compressor inlet compared to the HX40's 4" inlet. The anti-surge feature is also missing.

Thanks for the reply jusmx141. Now I'm trying to figure out if I actually have the 58mm compressor inducer. Do I have to take the turbo apart to measure that? (Again sorry for the newb question)

I don't knwo who made sheps but this same shaft was on Jake's car(Not evil eagle Topstreet) and he went 9.2 with no problems and I have read all over the suby forums about this company and their 1pc shafts and everything that has one loves them. Matter of fact everyone said it smoothed everything out not the other way around.

You will have to pull the compressor cover off to measure it accurately.

Slippi, who made that carbon drive shaft?

First adventure out on my build, with no more then 3 miles drive time and no more then 10-15 psi. I boost it twice and quickly let off, then try a 3rd time and I hear a screeching noise and boost is going nowhere. I get ZERO boost, get home and check for boost leaks. Find none and check the turbo, has quite a bit of shaft play side to side and from an eyeball has rubbed the housing. FAWK Me and a friend drop the turbo in 30 mins, take off the compressor cover/turbine housing and I find a slighty rubbed compressor wheel and slight rubbing in my compressor housing. No oil was in the compressor housing, turbine housing so I then begin to check my oil supply line. I crank it over (without spark/fuel) and have him hold the line over a drain pan. Nothing comes out, no oil, nothing. FAWK x2 I then proceed to suck on the oil line to see if I can get any oil and sure enough I get a huge mouthfull. GROSS I'm using the 90 air/air style oil filter housing with a -4an line in the correct spot according to RRE. Why am I not getting oil pumping out on cranking? I know my oil cooler gets oil as it gets hot as hell, I'm at a loss.

Where do I go from here?

A company called ACPT

Side note: Cars with HX52's will sound like absolute titties when spooling up. <Fact.

I hit about 10psi today at around 4800 with it and it just wanted to continue spooling up quicker and quicker.

Video please!

thanks for the help Andy! If i may ask, where are most of you guys getting your turbos? And how much are you paying. I see some VERY new turbos in here and i thought holset's weren't cheap! So, where are you picking these up. I saw turbotrader has some but, 1000 bucks isnt cheap. I might as well get a custom PTE for that price. What are you guys paying?

Well that's a bugger. It looks right to me, you have a 90 degree pipe elbow screwed into the port where the RRE diagram says "RRE oil line fitting goes here". All I can think of is screw an oil pressure gage into that port and see what kind of reading you get. If there is no reading you'd have to take that housing apart and see what the heck is going on inside it. This is one I want to follow because I haven't used that port yet, but probably will someday. I don't remember now, the one they label "un-used fitting" - is that another port you can use or is that one a no-no?
On the bright side, now we know how long one of these things will run without oil!

I was just out in the garage double checking myself. Pulled the plugs (all clean) and decided to redo my oil feed pressure test. Pulling the plugs allowed the engine to spin faster just using the starter. I do infact have oil coming out of the oil feed line, it just took about 10 seconds for it to start coming out. I guess I'm gonna attribute this to a poorly built Holset. I bought this turbo off ebay as "in new condition" It looked to have been rebuilt and a new billet compressor wheel was put on. I'm gonna call my local turbo diesel repair shop Monday and see how much a rebuild is gonna cost.

 

[dsm-onster]

Was this after a complete rebuild? Did you get metal from seating pistons into your turbo?

That is what an old clipped FPred will do.

 

[ceedawg]

You could get a core from goldfarb that has destroyed wheels for a good price jsut to get the housing.

That's good to know. Do you have a link?

 

[Mike1992]

The shortblock has 15k on it, I put a rebuilt head on it. But I'm gonna attribute this failure to an improper rebuild. When I got the turbo it did have shaft play and did look to be a fresh rebuild with no miles. I assume the rebuild was done by a newb without knowledge of over sized bearing. With the shaft play this thing has I can almost garantee its gonna need the main shaft turned down and new oversized bearings installed.

If the wheels touched the housing, you may have to have a rebalance or worse, you may have trashed a billet wheel

I certainly hope not, this was truely a rare find. The compressor housing shows the compressor wheel has rubbed, yet I cannot feel it with my fingers at all. The compressor wheel doesn't appear bent or anything serious. You can clearly see that in the pictures I posted above. I did take some fine grit sandpaper to the edges of the wheel and it seems to have cleaned the damage right off, I just hope it's salvageable. I think things will be fine with a rebuild though. Guess we'll find out.

Excellent! thanx! Is there a parts # list that tells would help me figure out which is the 17mm T4 core? Or should i just stick with this 18cm T3. I am going with a TS mani.

 

[turbodsm18]

Mike I just got your message......I will call you tomorrow and we can talk.. If It comes down to it, we will throw my hx40 on this bi*** and go with it.....

Wheel looks in good shape. . . Worth another shot to me.

MIKE1992....I think your turbo is fine...you should be alright....wheel looks good to go

MMM yea keep these kind of updates going. Turboner.

Yeah I bet that wheel is good. Probably when you get the rebuild just make sure you get what Tim at Tim's Turbos calls "balanced and blueprinted".

He is, he is looking a couple places locally to get it rebuilt....This is the worst I have seen a turbo as far as shaftplay goes. I work for a diesel shop and I have seen some BAD turbos, but this is the worse on car applications. So sad considering Mike engine bay and attention to detail is amazing, this is probably one of the cleanest dsm engines bays I have seen in a loooong time. I guess good things come with time though....
