My R32 currently in the shop with the H1C should know what she making in 2 weeks

[Dave926]

I Just picked up a hx35w. Could anyone tell me what size oil feed and return line i should run? And also which oil pressure restrictor im supposed to run on a 98 vr6. Any help would be greatly appreciated.

Not to be rude, but I put a considerable amount of time and effort into all the info on the first page of this thread, so why don't you try reading it?

Closing in on firing my H1C/HX35 up, pretty quiet in here.

[Dave926]

Awesome, nothing like the sound of an Audi 5 cyl at full song

Only thing that sounds better than a VR IMHO.

Idk, I've got one of each and the five cylinder still gives me chills when I hear it

Not to be rude back, but I can't seem to find what it is that i am looking for. Kinda like the first 5times i have looked. To be a bit more clear.... I just need to know what the normak oil pressure is on a 12v vr. And whether or not i need a restrictor. I am new to the whole turbo deal and was just looking for some help that i could not find. Thanks

You'll see somewhere around 30 psi at idle and up to 90psi at wot. Feeding your holset off the 12v oil filter housing is within spec for the holset's requirements based on the info that Dave posted on the first page. I think everyone will recommend that you go ahead and run the holset without a restrictor. If you come to find that it is smoking, you might need one. In that case I dont know which one it is you'll need but I'd probably just suggest grabbing whatever 034 or ATP, etc is selling.

I don't think any of us here are using a restrictor though so I doubt you'll need one.

[allmotorvr11]

Thank you very much. I didn't mean to be a smart ass i appreciate the useful research that is in this thread.... I just couldn't find that answer. Thanks to all

I have a 6-blade HX40 (Super40) with new rebuild kit that I will throw along. Looking to get either 400 plus shipping or trade for a hx30. PM me if you are interested and I will get you pics

I tthought the super was a seven blade?

[V-dubbulyuh]

^ There's also a 6-blade version.

ill trade for any smaller holset actually

[V-dubbulyuh]

^ What are you looking for? Got some H1C's here if you are interested.

[Eganx]

If anyone is interested I have a Holset HX35 with a 12 cm hot side for sale......good shape, came off a dodge with 90k........hit me up if your interested

[acee_dub]

Getting close to throwing mine on too... next step: weld up a quiet 3" exhaust with a bypass switch

[D3hd3nd]

Okay so my eyes hurt from looking/reading through all these pages but who's running a HY35 or knows of someone i can search/lookup to check into it. I'm going to guess that the answer's somewhere on here already but i must have missed it, help is appreciated

EDIT: Figuring an HY35 runs similar lb/min as the hx35 it should be able to make a decent bit over 300 i'd assume, aiming low on the assumption added with the fact that it's only a 9^cm exhaust housing it must get choked out compared to say a 12^cm on a hx, correct me if i'm wrong?

[R32 Lego]

Hey all i posted up here a few times while my car was in the shop. i have a 2004 R32T with a built motor i am running the Holset H1C on my R32 i made 483wtq an 462whp on 20psi on a front wheel drive dyno not a all wheel. i would have made more but the hot side on the H1C was to restrictive what would you all recommend for a upgraded hot side on my H1C

[R32 Lego]

[my2000APB]

What cm size is the current hotside, itll be inside the hotside on the wall

[R32 Lego]

i dont know the current cm size and well have to check and see if i can still see it no that its in the car

[R32 Lego]

after it was dynoed and picked up i was told there are 2 available hot sides that were bigger and would be less restrictive.

[V-dubbulyuh]

Pretty sure I got one here with a 21cm, think that is the larger of the two for that turbo. Someone correct me if I'm wrong.

[R32 Lego]

what do the H1C come with when you buy a H1C or are there different hot sides for each H1C

[R32 Lego]

how do check my hot side > it already all bolted up and in and would be a lot of work to just find out my cm size is there a website i can search the model and serial number to see the cm size on my current H1C from what you have side and the guys at the shop saying there were 2 hotsides i could pick to upgrade my hot side i would like to say i have the small H1C

Here's some progress of my HX35 7blade install, going on my 97 Jetta ABA-t. My Holset finally showed up at work today and since it was slow i made my downpipe adapter and wastegate modifications i needed to do before install.

First i made my downpipe adapter; took the downpipe connector off the turbo sawsalled the cummins flange off the end and welded on my 3 bolt flange to match my downpipe.


Here's a picture the adapter on the turbo for fun


Next i took the ATP 7psi wastegate actuator, cut it up and added a midsection to accommodate for the length needed to reach the flapper arm.


And a picture of it installed and adjusted to proper length.


All i want to do yet before i bolt it up is gasket match the exhaust housing and port out the wastegate hole in the exhaust housing

21cm was the largest offered in the Dodge Cummins setups. More common are the 18cm's. You may have a non-wastegated 14cm or 16cm if swapped on from an aftermarket vendor.

what do the H1C come with when you buy a H1C or are there different hot sides for each H1C

89-93 Dodge Cummins. 89-91 NON-Intercooled came with a 50 or 52mm compressor while the 91.5-93 came with a 54mm compressor. 91.5-92's may have come with 21cms. I have a late build (04/92) 92 with an 18cm housing.

Smaller ones came with 18cm. However, people typically upgraded them. I know you can look inside along the divider on the exhaust inlet to tell.

Looks like he as an 18cm. I just don't see how that would be restrictive at all on his motor setup.
Any restriction is perhaps more exhaust and/or misc piping related. Not for nothing his numbers are not bad at all either for 20 psi give that his turbo prefers a mid-20's and above operational range.

If he is really interested in getting rid of the 18 I have a 21 here I can offer up.

[dodger21]

The popular Banks Power Pack at that time came with a 14m non-wastegated housing so it is very possible to have a 14cm and that will be restrictive.

i have 3inch exhaust piping all the way back from the turbo and the boys over at eurowise side it was my hot side that was restricting me from making more power. i am trying to brake 500+ at the wheels. i well get you all a more detailed parts list of what i have. may be you all can help me get to were i want to be so just tell me what you need to know.

[SlantSix]

Got Holset H1D. 8361-31220 used in Sisu/Valmet diesel engines?
What u think about this in Vr6? Is this used in Kinetic turbokit?
Atm looking for max 300hp, damn 02C dont wanna break it
pic 1, 56-58mm
pic 2
pic 3, aprox 56-58mm
pic 4. .63

i think he can do it witha better hotside, he's pretty close as is
