im looking into switching turbos setup and going with a 6 blade HX40 in a bolton .63 A/R turbine housing its a more expensive turbine housing compared to the BEP .55 ($285) this is more in the $350 range once you add in shipping cost, though i dont have a final price yet.

so is going with a .63 housing really worth the extra cash to get the most out of an HX40?
what do you guys think?

heres what the housing would look like more or less

It'll flow better than a .55 bolt on, I hope. Is it enough to max it out, I'm not sure. The best choice to max out the hx40 would be either the BEP .70 T3 housing or the stock housing which for the hx40 I believe they are all HUGE t4's around 18.5cm. Getting a 12cm TS turbine housing off an hx35 and having it machined for the hx40 would be a SICK street turbo. The power band would be amazing.

Who makes the .63 bolt on housing for the hx40? Or did you machine an existing housing?

No wonder you have a red little square, Im well aware of turbine housing options, look at my signature... I'm looking into a new possible option and wondering what other DSMers with experience with the .55 BEP housing think

No one makes a .63 housing yet...
 
I'd say no, at least not to me it wouldn't be. Although, for you, the bigger the A/R the better being FWD and squirting E85. Personally, since the initial cost of that HX40 is relatively cheap compared to other turbos its size, I'd try to make the most out of it and get a FP35 turbine housing with a .68 A/R and machine it like Hugo did to his.

$400 + cost to machine.

EDIT - Just realized, are you doing this for marketing research or your own personal? LOL

:dsm:
 
Thanks ass.
When reading your post, nowhere did it say that the turbine housing you were asking about did not exist. You even gave a price for the said housing. If you in some way were asking if people would be interested in a .63bolt on housing, then yes, they probably would be. You didn't ask that though........

"so is going with a .63 housing really worth the extra cash to get the most out of an HX40?"

I answered this and said it would not likely be able to max out the turbo. Maybe you should search and you'd find out what others think of the .55 housing.

thats not what you answered.. matter fact you didn't answer or positively contribute to this thread yet your answers were actually just more questions
 
Well, I think it's a good option (if it was one) for most DSMer's since it would free up some airflow over the .55 BEP and it's not a v-band at the o2 like the FP saving cost.

:dsm:
 
It will flow WORSE than the .55 Bullseye housing because of the off-centered volute design. This housing is known to ruin good-flowing PTE turbos- it robs around 10 lb/min of total flow from the 6152. The Bullseye housing is designed with a centered volute like the FP DSM housings where the PTE is more like an OEM Mitsu housing.

Another negative is it's carbon cast instead of stainless- I've seen threads pull out of these housings when they were brand new.

Looks nice, but I'd stick with Bullseye. ;)
 
Hmmm really? this is the housing that comes with the GT35R

heres a down shot

Too bad your a complete ass. That's probably bad for business. I know it affects my decision to ever buy from you.

'' The best choice to max out the hx40 would be either the BEP .70 T3 housing or the stock housing" - I believe that's an answer.

"it would not likely be able to max out the turbo"- Huh, looks like another answer. Crazy.

It completely amazes me on how many d-bag's with d-bag responses are on this f*cking forum. I wasn't rude, offensive, or incompetent in my response to your original questions.

How do you know all this without having any info on the actual turbine housing itself? LOL

I still think it would be a good option for ignorant DSMers like me who would just look at the .63 A/R and bolt on convenience. ;)

I agree with you. You put in your opinion and asked a simple question. How is that not contributing to the thread? I too am amazed at how many condescending pricks are on this forum. I don't have anything to contribute to this thread except to tell the OP to chill out. End rant, sorry.
 
Has anyone ever tried a .82 housing? I only ask because its pretty much THE housing to use with a 35r and considering a super40 should flow more than the 35r, I would assume this would be a good a/r to truly max out the hx40. I wonder if Talondave could have trapped even higher with this instead of the .70 bullseye?

look guy your already on thin ice apparently and your certainly not helping yourself

those are great answers to question that wernt asked, for one this discussion is about bolt-on application, I didnt ask what the best housing to max out an HX 40 was did I?

nor did you say "it would not likely be able to max out the turbo" you said "It'll flow better than a .55 bolt on, I hope. Is it enough to max it out, I'm not sure."

read your 1st post again, because you apparently forgot what you said

oh and ditto on this

where was I Rude? This thread is about Bolt on options, not T3 that's why he wasn't contributing. He is the upset one, calling people names and such getting all worked up
 
Ok big man LOL

Dude, I called you a d-bag because the first thing you said to my response was about me being in the red. Then you asked if it was enough to MAX out the hx40. I said no. I gave you better options to max it out. Didn't know me giving you T3 options would result in you bashing me on my oh so powerful reputation square.

I still think it would be a good option for ignorant DSMers like me who would just look at the .63 A/R and bolt on convenience. ;)

:dsm:
The thing is PTE offers a bolt-on .48 and .63 housing with ZERO published data on either one. How are we sure this is the .63 housing? Doesn't look anywhere near as big as the Precision T3 .63 to me.

Compare the visible size of the volute on the exterior of the BEP bolt-on housing to the PTE housing.

I said that because instead of addressing a bolt on option which is what this thread is about your rambled on about T3 options which I know plenty. I run a full T3 T/S HX35 12cm setup I know that's one of the best options but its not cheep, I'm exploring cheap bolt on solutions for HX40s
 
Ok but the fact that you weren't 100% clear in your first post isn't my fault. Nor did I deserve being belittled by you.

By Justin's pictures, it doesn't seem to be close to .63 a/r. Maybe .48. But like Justin said, no one has any info proving anything for them. Gofer gave the best suggestion for bolt on housings with the FP housing machined to fit. Very well designed housing that is practically the best of all worlds. Good spool, flow and best of all.....bolt on.

Is it cheap? No. Will I get slammed for going against the very specific parameters of the thread that you want? Most likely, yes.

I'm gonna say adapter plate...... Look at what Devins did....8.6's and set the 35r record......no hta....off the shelf 35r.
 
Without a doubt the FP30/35 housing is going to be your absolute best-flowing bolt-on option, and those housings are stainless as well. I believe they're a published .69 a/r, and it's a centered-volute as well. The only negative is they force you to run a 44mm v-band wastegate which limits your gate placement options unless you weld the v-band shut.

Hate you because of all your knowledge. That's good info you posted, I was impressed that you could look at a few pictures without any info other than A/R and you know the in's and outs.

Are all BEP housings center volute and Mitsu housings off center and the center volute design increases airflow because it's more efficient?

the title of this thread is "DSM bolton .63 A/R HX40" how much more clear does it need to be man...

and I know all about the FP housing Gofer mentioned, I machined it. and its not bolt on since it has a V-band o2 housing side to get the housing have it machined and building a new O2 housing your talking $600+
 
Justin do you have some comparison pictures of the volute of the BEP housing? im interested in seeing them side by side
