If its the Hx30w (wastegated) model then it can be adapted to work on the hy35.If its a non wastegated hx30 it cannot be adapted.Remember the 6cm/.38 housing is a heck of alot smaller than the hy's 9cm/.54.Somthing like .46-.48 would be really nice to have.

My dad and I have been doing some reworking on the hy's turbine housing to drop the AR to aproximately .48 ,It spools alot better now

.

I had 2 hy's and both turbine wheels measured different in size :?.So it turns out that the one turbine wheel was smaller where it exits through the exducer bore.The turbo was in ok shape no play or anything and the wheel almost looked like it had been made smaller from the factory,no wear on the fins or sharp edges.It did have a weird ridge in the wheel where the curve of the wheel changes,this is where the wheel changed in size for whatever reason.

Anyways this gave a bigger parallel clearance between the wheel and exducer bore all the way through.All we did was machine up a sleve to bring the wheel to housing clearance back down to spec.

So by making the exducer bore smaller we have effectively lowered the AR to somthing like .48.

The wheel size difference on the smaller Dia was somthing like .070 thou :shock: huge, while the bigger dia of the wheel remained the same within .003 thou :? We have no idea how this happened but we'll take it

yea,it had a wastegate on it,i remember that much
ill do a closer examination tomorrow

you modded your housing to work,but can i just "slap it on" ifi get one of these housings???

Nope, you'll still have to machine 2 parts of the housing for the hy's wheel and heatshield to fit.

any pics andy of your housing modifications to reduce the ar?
thanks,

I knew I should have took a pic

.Next time its apart I'll definitely take one of the housing and wheel.

therabbittree · « **Reply #83 on:** August 10, 2006, 04:31:59 pm »

well a pic showing what to machine and how much etc ... etc.. I want to know what to tell my machine show to do to my hy 35 housing.. or heck .. if you want the $ I'll send it to you ... for you to modify for me.. let me know I am dead serious too.
Thanks

The only problem with the mod I've done to my housing is that the wheel has to be smaller.As mentioned I have no clue to how the wheel on one of the hy's I had was smaller?

If you could get the wheel downsized like mine then you can make a sleve for the smaller wheel to lower the AR.

It was pretty simple to calculate as the hx30's wheel(.38AR) was a certian OD and the hys wheel(.54Ar) was another cretian OD.So to get the .48 AR we luckley had a worn down wheel?? that just happened to be in the correct size to make a .48 out of it.

Remember both wheels and housings hx/hy had the same nozzle opening dimentions so the housings outlet(exducer) DIA is what makes the AR bigger or smaller.The turbine inlet is simply sized for the needed flow of the turbine outlet.

I think this makes some sense

i got the freebie housing tonight
then i stopped over at manifold dudes place where my hy is
he wasnt there
i wanted to see what needs machined on the housing
oh well,maybe tonight ill just try to clean it up some in the garagwe+ snap some pics

iknow this turbo was blowed up
its exhaust wheel was contacting the housing some
lol maybe i wont have to machine as much,and the wheel did it for me :lol:

hillfolk'r · « **Reply #86 on:** August 12, 2006, 01:03:57 pm »

i brought the housing to manifold dude
he will draw it up on cad what we need to machine,but he wants to machine more than 1,for cost purposes
anyone else got a hx30w housing they want modded to fit a hy35 turbo ??
how bout you rabbittree??
anyone???

its an interesting thought and I've been trying to get a used holset for close to 8 months now off of EBAY that I could rebuild, etc. but still haven't come across a "good" price for an unseen "needs rebuilt" unit.
Ever since the mTDI project started I've been looking with no luck

Any ideas? What kind of cost are you looking at?

i dont know ore its some usable information,
but someone with a 1.3 GASSER just made 355hp@2,2bar(32psi) with a Holset HY35W from a 7.0diesel truck
it makes boost on 3000rpm, between 6000-9000 he got good power.

joe go on a dodge website like the turbodiesel register i know there is a hy35 for sale for $300.. most are about that proice tahts what balke and I both paid fro ours.. and they don't need aa rebuild as most are low mile takeoffs when th owners put a bigger turbo on there truck... blake price one out at your job for me i may be about to swing it if its cheap enough...let em know i will look around today at at truck yard for one..later
