Looks like with the FP mani you dont need to mess with the flange or anything is that correct? Did you dent your water pipe?

I have the Hx40 with FP manifold and i had to bairly dent my water pipe.

Very nice, I would rather sell my tubular mani and get the FP manifold, than mill or reweld the stupid flange, the FP mani looks bad ass anyway. thanks.

So can anyone snap a pic of the "anti surge" opening on the hx35? I'm looking for the openings in the webbing part. I don't see any openings in the hx35 that I have here. What I mean by opening is where the webbing is there appears to be no entrance cut into the housing that would feed air to the compressor wheel. It looks like on the inducer gets air like any MHI turbo.

Post a picture and your numbers off the turbo

Yes is there a tag? To be 100% sure you will need to pull at least the compressor cover and give us the measurement of the inducer and exducer.

1994-1998: HX35 = Webbing + bolton cover + surge port + 56mm inducer + 8blades + 12cm^2 turbine housing + wastegate
1994: WH1C = Webbing + vband cover + surge port + 56mm inducer + 8blades + 12cm^2 turbine housing + wastegate
1991-1993 (intercooled): Big H1C = Webbing + vband + no surge port + 54mm inducer + 8blades + 18.5/21cm^2 turbine housing + freefloating
1991-1993 (non intercooled): Small H1C = No webbing + vband cover + no surge port + 50-52mm inducer + 8blades + 18.5/21cm^2 turbine housing + freefloating
Up to 1990?: Baby H1C = No webbing + bolton cover + no surge port + 45mm inducer + 7blades + 18.5/21cm^2 turbine housing? + freefloating

Ive been trying to follow these holset threads, but it takes some time to get through these 30 pagers! Deffinately seems like the holset scene is growing quite a bit from that first thread though. How's come you guys have chosen the holset platform vs. the Borg warner?

delta448 · 03-13-2009, 08:49 AM

I'd have to say that cost is probably the biggest reason. Holsets are easier to find used and can be rebuilt for a significantly smaller total investment. Even with the added cost of a BEP housing, a rebuilt Holset can be had for around half of what most vendors are charging for BW units.

toofast82 · 03-13-2009, 09:08 AM

I think alot of people are going holset obviously for performance and price as they can be had used for cheap and are easily rebuildable. Borg warners are gaining popularity because of their extended tip turbochargers that are making great numbers. It is more difficult to find the BWs used but they are rebuildable as well. I think a lot of people are switching to BorgWarner and Holset partly because of the cartridge quality versus Garrett.

I think you hit the nail squarely on the head.

A relatively low cost option and a strong reliability factor makes for a nice overall package.

Don't listen to them

Its because dsm-onster made a magic potion and spread it around to us and has us all under his control

e85_4g63 · 03-13-2009, 02:00 PM

I heard Chuck Norris started working at Holset.... You know that's why everyone is making the switch

dsm-onster · 03-13-2009, 02:28 PM

NEVER! Chuck Norris only races turbos he's been given in a sponsorship agreement. The rest of us jerkoffs have to go out and make our own results. So they did . . .But, it's not about the results. It's a religion

I just got back my second eprom ecu socketed by ecmtuning. And I'm cutting holes in my auto AWD firewall for the 5speed now

. No more FWD with a bolton hx35 turbo!

Slippi84 · 03-13-2009, 03:55 PM

Chuck Norris's turbo hits full boost before you even hit the pedal, and hits harder than anything in the universe.......that is other than a round house kick to the face by Chuck Norris

Black_Bullet · 03-13-2009, 04:37 PM

Yes and Chuck Norris turbo even comes with the Texas Ranger mustache!!!

Weapon-X · 03-13-2009, 05:17 PM

............ Full of WIN here................. Not only can you learn about the ever growing in popularity Holset craze, But you can get schooled on your Chuck Norris facts.

talonDSMerr · 03-13-2009, 06:19 PM

Haha you guys are ridiculous..

More on topic though, what size bolts does the BEP housing use on the o2 housing side? I tried 8mm, 10mm, 3/8", 5/16", none work. Do I have to get the $6 oem bolt?

kawboy · 03-13-2009, 06:40 PM

Use your stock bolts?

And they are cheaper then $6 from JNZ. I just bought a few.

talonDSMerr · 03-13-2009, 06:52 PM

I know, one of them snapped in half though. Thanks for the tip.

Morphius · 03-13-2009, 08:51 PM

Looking for some feed back to the brief post summary in the first post of this thread. Useful? Useless? I did the first page. The intent is to make it brief but highlight the important stuff.

It's time consuming, but if I can keep up with it, it's not too bad. I might try linking to each post and possibly the poster.

Also, can anyone explain how to post a link, but you name it something else. Example, if you visited the first post, the post summary, post 2 is linked, but how to I make it say "post 2" but it is the link listed?

Like this?

post 2

When you click the link to insert a URL, paste the URL, then hit ok. Then the link you posted should be highlighted. Just type "post 2" or whatever over that.

The same as stock.

ill be doing the swap soon, did you cut for the master/cables from inside the car or under the hood?

That's what I thought, but it didn't thread in. Maybe the thread pitch was wrong. I'll check again at ACE tomorrow, they seem to have a better selection than Menard's.

blacksheep86 · 03-14-2009, 12:22 AM

Hey guys, I got the car up and running tonight. It feels good for being 15psi at the moment but I need to check for some boost leaks.

Yes I am using the PR O2 housing. I like it a lot but we did have to port match it and take of a good amount of material.

I did have to dent the water pipe.

Hopefully after this tank of gas ill have E85 and somewhere around 30psi

.

Ill have some engine bay pics up soon. My arms were too tired to hold the camera steady.

Spidey · 03-14-2009, 06:50 AM

Good info and nice setups everyone, hope to have my T3 HX35 setup back up and running this summer

You need to cut on the inside of the car. See my progress up to just before cutting.

Morphius, are you going to actually do the minutes for these threads!!! That would be a huge undertaking! It would be awesome to get a table of contents. Something like an outline. It would modifiable too. Just add or change headings and subheadings; and add or change posts relating to the headings and subheadings. This would be good to do with the other threads. I remember stuff back to the beginning, but finding it for a reference is

!!!

AHALLA05 · 03-14-2009, 08:34 AM

Jeeze, I post yesterday and there is already 20+ posts since! Its like you guys have a cult of holset gurus

. Reading of some awsome setups Blksheep86, Maglin, 1fast2g, and its looking like these are gonna be posting some fast times to the list this year!

The more I read the more I wanna make the switch from my 3076 to an hx. Im looking for a setup with the fastest spool possible utilizing the t3 platform of my shearer mani. I like the spool characteristics of the 30r but after reading, close to the same spool can be had along with a load of more topend from these turbos. Just looking for some suggestions.

dsm-onster · 03-14-2009, 11:01 AM

Well.

If your topmount manifold is an open header design:

1. The t3 .70 a/r bep turbine housing with the hx40 will spool to 20ish psi by about 4400rpms.
2. Get a t3 to mhi adapter flange, a bolton .55 a/r bep housing and run the hx40 that way.
3. 7blade hx35 or hybrid hx35/40 with the stock 12cm^2 hx35 turbine housing. The 7blade hx35 compressor map is 6lb/min more to the right than the gt30r. Radius the divider. 20ish psi by 4000rpms.
4. 7blade hx35 or hybrid hx35/40 with the .70 a/r bep turbine housing. 20ish psi by 4000rpms.

Best option here is number 2 in my opinion for the best balance of spool and flow. Id swing to number 1 if you're willing to give up a little spool for all the topend you would ever need. Because 20psi at 4400rpms in 3rd gear and more than 650whp potential is incredible in my book. This is at least 100whp more potential than your current setup. Not a bad sacrefice.

If you're top mount is a divided runner type:

1. I recommend a 16cm^2 hx40. This is a t3 bolt pattern hx40. The 16cm^2 housing with a true divided runner manifold will be faster. You can't get the hx40 with the common 19cm^2 divided housing but that is a t4 flange.
2. You can get a 7blade hx35 and use an 18.5cm^2 turbine housing from an h1c. This will be t3 flanged and should flow enough to get the most from the 7blade 58lb/min hx35 compressor.
3. Another option is to take a h1c 18.5cm^2 ahdn ahve it machined for the hx40 turbine wheel. It will be slightly laggier than number 1 but will flow more up top, still be t3 flanged and those parts will be more common to find if you having a hard time tracking down a 16cm^2 t3 hx40.
4. Yout can buy a t3 16cm^2 turbine housing from htturbo or city diesel or other diesel turbo supplier.

Best option here is number 1 in my opinion for the best balance in spool and flow. I'd lean toward number 3 if you want to sacrefice a little spool for all topend you would ever need.
