jrohner is right, look at the bep .70 a/r housing. But in all practicality, the stock 12cm^2 t3 divided housing that comes with the hx35 gives you great flow. The stock hx35 hotside (housing and turbine wheel) has done 132mph with a full weight 1g . It's got enough flow to see the full potential of the 7blade hx35 compressor. And it's free. You will need to fab up your own o2 housing vs. buying what ever fits on the .70 a/r bep housing. But still that will be cheaper. AND the turbine housing is already there, free since you buy whole hx35s usually. . . Be sure to radius the divider or get hte PTE t3 divided gasket made for open headers to match up to divided t3 housings.

I actually got on here to PM you about this until I started reading this page. I just picked up a hx35 7 blade with the stock divided T3 housing yesterday. My question is will the outlet bolt to a typical T3/T4 5 bolt flange or do I need to find the stock outlet and fab one up from that? Im hoping its the same flange that I can get from forcedperformance or extremepsi so I can get it ordered today.

The smallest t4 flanged housing I've seen has been the 18/19cm housing. They are the same size BTW, the 18cm and 19cm housing. . .

The bolt pattern for the 5bolt holset outlet is different than the 5bolt garrett outlet. Though it is 5bolt pattern, it is spread out much larger. And many of the times the outlet has a 5bolt pattern with a flange bolted on that converts over to the holset vband outlet of various sizes. You can get the holset bolt pattern outlet flange from ebay last I looked. Or you could get the holset flange that converts from 5bolt to vband froma blown holset. If you already have a turbo that is internally gated and has a vband outlet then you already have the 5bolt-to-vband holset conversion piece. Just weld the o2 housing turn down right on the vband side, since you can still unbolt the whole thing from the turbo on the 5bolt side.

So I am sitting here with my hx-40... changed my mind once again. What would be the smallest t4 flanged divided housing for the hot side thats avalable, any ideas where i might come accross one?
thanks

Im running a T4 17cm housing on mine. It took me about 4 months to hunt it down though. I got the whole turbo from Goldfarb with a bad compressor wheel. I had a good 60mm 7 blade wheel and cover, so now i have a backup CHRA and the exhaust housing i was looking for.

I forgot about that housing you had!!!! They DO exist. I've only seen/heard of yours. I guess you're the lucky SOB. But remember A/R is NOT everything. A larger A/R housing with a smaller wheel can spool the same and have less backpressure so that if flows the same or better. Nevertheless, I think I remember talking to you in PM and that housing being perfect for your goal. . .

I havent had any time to to do any tuning or even drive it much really. Ive been too busy trying to get my gf's car together in time for the shootout. I was only able to make 4 passes at the track and wasnt doing any tuning because of the event i was running it in. I was basicly relearning how to drive the car. The third pass it went 11.97@118 with a 2.0 60' (bogged it) and missing 4th. My previous best was 12.2@114 on my old setup and a clean pass, so i was just happy to get in the 11s. On the 4th and last pass i still bogged it a little with a 1.84 60' and shifted slow to be sure i hit all the gears and ran a 11.62@125. I thought that was decent for its first day back to the track.

Ive got about 300 miles on the new setup now and it has great street manners. Im more than happy with the power so far, but i might try a 19cm housing.

I want to get it dialed in a little bit better, raise the boost, and practice my launches to get rid of the bog. I usually have 60's in the 1.70 range or better. It will be trailered to the shootout though, so i wont be as afraid to break it. By then i should have a post in the results thread.

If anybody wants to say hi at the shootout, ill be the guy in the red Peterbilt with flames. It should be easy to find.

Man, post in the results thread what you ahve. That's actually some great results for a budget turbo and a basic build on their ?1st? time at the track witht that car. . .

Anyone thinking about or into Holset turbos should watch this video!!!

If anyone is interested here is a few pics of what the hx35 would look like with a true twin scroll setup.

Wow that's a nice setup! I'm regretting having to sell my 8-blade HX40 now :-/

If anyone is still looking for a bolt on housing I found this on ebay.

^ ^ That's Goldfarb. ^ ^

Wonder if they're just not moving enough housings, or they're using eBay to branch out a little? The pricing is higher than I've seen.....

They've used ebay before. I bought my wh1e from them through ebay.

If anybody is looking for a T4 17cm hx40 exhaust housing, there is one on ebay right now.

Just thought I'd share my twinscroll HX35 setup as well. I'll grab some better pics later on this week when it's running

more pics!

These are the only other ones I have of the turbo in the car. I should have taken pics of the IC pipes and downpipe before they went in the car. I had my welder make me some custom v band flanges to mate up perfectly to the compressor outlet and turbine outlet, really nice work.







I'm just waiting for my new oil drain to come in, then it should be pretty much good to go!

What exhaust manifold is that ? ^

Well kp116 clicked off 134.6mph with the bolton hx40 using stock intake manifold . Click! He's is number 6 to see +130mph with a Holset turbo and the 3rd guy to do it with a .55a/r BEP housing.

Anyone with a big frame holset like the hx52 sized know if you can put a garret or borg compressor cover on? I want to change to a larger race cover with the 3" outlet like the GT42 or the s374 race cover and I don't think holset ever made a cover like that for these but I may be wrong.

Where did your source the oil drain? I'm still trying to source my oil feed, oil drain, and compressor outlet. I'd really like to keep the v-band, otherwise I'll weld an elbow onto it.

It's a custom piece, made in Edmonton AB.

I picked up the -10AN oil drain and head oil feed from extremepsi. If you want to keep the v-band outlet, just pick up a 2.5" v-band clamp and flange from vibrant. Just make sure you have room for the clamp, as it's a bit larger than a silicone coupler is.

Figured everyone would want to see pics of the HX40 with a T3 .70 A/R BEP housing mounted to an ERL manifold on the car, so here's the setup mounted to my FWD (even though it's permanent home will be on the AWD):






Don't mind the mess, the engine's on it's way out of the car...I just snapped some pics while there was nothing in the way. You can see how the ERL manifold allows tons of room for the turbine housing to clear the block and the compressor cover to clear the water pipe.

I am going to be running a WH1C with the BEP DSM Bolton HX35 turbine housing with a 44mm wastegate on an SS o2 housing. The lowest I'll ever run the boost is probably 20psi. Should I port the wastegate hole in the turbine housing? How's the boost creep on these bolton housings?

If you're running an external off the O2 housing, then I'd port the living hell out of the BEP housing. It can't hurt.

yea port it alot, im running a 44mm of the o2 and i ported it alot and i am still getting some creep if i do a pull from 2k up to 7500, only creeps like 1-2psi

boost is set to like 22ish and i see 23/24 some times 25
