Holset Turbos

Ok since its not exactly clear anymore, This is for interested people wanting to know how many Holsets are in use and how they do with them.

I have a H1c with a modified 18cm housing externally gated Im running 20 psi with 680's and a maft. I ran 8.46 @90mph in the 1/8th I run dead even rolling start in 2nd with a buddies ls1 camero who dynos at 312rwhp Im also awd. In summary Im happy with the turbo it is alot better than the 14b it replaced, the only thing I would do differently is to get the bullseye housing or a 12cm stock housing. I piad 150 for it on ebay so for that kind of coin what can you complain about.

Who else is running these and what do you think of it.

My Car.

98 tsi Awd

stock 6 bolt -bal shafts
maft custom 21/2" piping
stock side mount
water/alky inj.
stock pump 3/8 fuel line
afpr
680cc injectors
3" exaust from turbo back

asfar as I can tell there is no compressor surge, Im running 20-25psi so maybe Im above the suge line. An h1c is supossed to be the same as a hx35.

You should list all your mods to your car too. Engine size, exhaust, etc. (again, if you already have in the other thread.)

Do you have any issues with compressor surge? I read somewhere (I think DSMTalk) that someone had issues with compressor surge, given these are being run at boost levels lower than what they were designed for.

just for your viewing pleasure i posted 4 pics of 2 diffrent billet comp wheels i have.

BGRIPTP · 07-25-2005, 03:00 PM

I am also in the market for a HX40 with the Bullseye Housing, lets see some good reviews and info...

sweet97 · 07-25-2005, 04:34 PM

If my Turboonertics 60-1 does not perform well after it's rebuild I am considering the HX-35 but there just isn't much feedback available. Please those with experience please share! Mark

with a fuel pump and a intercooler your going to fly.

Well I bought a Holset today. I got the HX-35/40 hybrid that GRE performance was selling, slightly used. I will have it friday and hopefully have it running the same day. Mounting it to a new DNP header also. I am having my Turbonetics 60-1 rebuilt, new CHRA and turbine housing and told Joshua I would sell the one I liked the least. He said I will be selling the 60-1.
The problem will be fabbing a 4" intake pipe so I can retain my COLD AIR INTAKE! Maybe Dave at dejontool can fashion an intake with 4" piping.
Anyways I will be able to have some feedback soon. I have had an EVO III 16G, 50 trim, 60-1 and now the HX-35/40. Mark

There is no doubt that you will be happy with the Holset turbo. It is a solid performer, the turbine and compressor wheels are much more efficient and have better design characteristics over the 60-1. The 60-1 is a good turbo but it is not in the same league as a hybrid Holset turbo. For those of you out there with the "MWE" Map Width Enhancement compressor covers, make sure you really take advantage of that feature and use a 4" intake. I tested a 3" and 4" intake and there was a near 250 RPM spool difference between the two on my car!

Really I have a 3" cover Ill have to look for a 4" now forsure.

sweet97 · 07-27-2005, 03:12 AM

Thanks for some more encouragement Josh. Anyone know where/how to get a 4" inlet pipe that will allow me to use my filter in the old SMIC location? That's where i run my 3" and do not want to lose the CAI advantage either. Mark

For the 4" pipe, I used 4" exhaust pipe and cut and welded wedges together. This worked out perfect so I could use my new 4" K&N.

I'm running an Hy-35 (2002) on my 87 Mitsu Starion, 2.6L. I love the turbo!!! It spools almost as quick s the tiny 12a I had on it stock. I ran it on the TBI setup for a little bit this year but have since MPI's the car. It only got better...I have run it up to 14psi and it pulls like it never has before. I'm waiting to crank up the boost till after I get the new P&P head on, with the MLS and ARP's.

I have noticed a tiny bit of compressor stall, but I'm only running 9psi around town and it's the real low boost setting I notice it. It's not always either.

I know this is the DSM forum, but I've been follow the other Holset post and thought I would add my comments.

These are my mods.
Stock bottom end 2.6L w/BS
Shaved head
3 angle valve job
Schneider 274 cam
Mechanical lifters
Recurved distrib (soon to be EDIS)
E2315 High output fuel pump (going to replace with a Walbro)
Customer header I built (Equal length with in 1/3")
Customer adaptor plate I made to addapt a MX6 MPI to my head
Ported intake
65mm Ford TB
2 1/4" Hard Pipes
4" Intake Pipe w/a K&N cone filter
72lbs Delphi injectors
MegaSquirt MSnS stand alone fuel management (soon to control boost and spark)
3" Down Pipe
2.5" full catless exhaust w/a Hooker Turbo muffler
Modified cooling system (need a bigger radiator I feel)

Those are the majority of my mods. I'm excited to put the new head on with the MLS and ARP's and crank up the boost to 20 psi.

I also have some minor things to do here and there which will wait till winter.

I'm a member of starquestclub.com. Welded wedges would have some sharp edges and the thought of some slag coming loose and going into the turbo frightens me! Thanks for 1 option and great to see guys advancing the Starion/Conquests! Mark

MitsuMark?

I'm esirtype?....

I'm not worried about slag, or anything coming loose. I cleaned out the inside of the intake pipe with a sanding paddle bit on the die grinder.
I'm loving this Holset!

Well let us know how it spools on a 2.0L, I think GRE performance was getting 20+psi by 3900-4000 rpm on a 2.3L

the one in the red pic is a 7 blade hx40 [they have 6,7,8 blades]
the second and third pic is of a 55mm cnc billet wheel [street]
the fourth and fifth pic is of a cnc billet 72mm [race]

sweet97 · 07-28-2005, 07:00 PM

Do the Holsets come with the MWE covered with the "silencer" or uncovered and why? Thanks, Mark

No one knows why it seems most remove it? Has anyone tried both ways and found one better for spool? How about a poll, which way do YOU have yours? Mark

Its only on there for noise purposes. Im sure it doesnt effect spool at all.
But hey What do I know.
