Can anyone measure an HX35's compressor cover diameter? I'm trying to figure out if this shit will work. Otherwise I'll be paying with an arm+leg for a divided turbine t3/t04e 50trim.

[Minor Threat]

Will measure for you tonight, Joey has approx measurements I think. I know it's at least 1 inch more across.

[ryan89crx]

Just over 8" if you don't include the WG or comp outlet. With the comp outlet, its about 10 1/4"

[HiProfile]

Well the t04b cover in my signature is 6"...I'm wondering if I could stuff the HX35 in the same spot with a GSR? The t04e cover is only about 7", and as you can see, it's tighter than a virgin with A/C in place.

One thing I might do is mod my bracket to move the AC compressor upwards. That would move the lines out of the way.

T04 and an HX35


Compared to a sohc

fuck that looks huge on a d

:edit  nevermind somone already got it

[onlyflash944]

ryan,
what are you going to do about a waste gate?  just bolt/weld the stock flapper shut and use an external?

[turbob16hatch]

I'm not up on my holset info but couldn't you find an old comp housing and have it cut to fit the larger wheel?

like an 80's h1c or w/e. they have to be smaller.

[Joseph Davis]

T04E S-cover is 7" scroll, HX35 is 9".

[Joseph Davis]

Edit, from my notes:

Scroll is 8" across. From leftmost of the scroll to the orange cap/comp exit is 9"

Just going to tack weld the flapper shut and run an external

where do they sell replacement shafts?

tack that fucker realllllly good.... my tacks broke and i had to rig the fuck out of the car on the spot at the track.  thank god for mechanical wire

O where great grand wizard?
I searched and have no luck..only ching chong site

oh and google search is hard...... 

[7808]

or try places that work on turbo diesel trucks

Thanks for the extra info. Better late then when I actually need the info, I always say.

I think I'm going to be forced to use a 50trim Garrett, too bad. However I found a smoking deal on one with a divided .78ar ATP housing. 3" v-band and everything. The place is called APtuning.net, I'm just hoping they're legit. The address and phone number seem to fit.


I'm hoping to mix a divided manifold with a special "quick spool valve"... If my wish comes true, it will be like spooling on a .39ar housing with the topend better than a .63ar.

[turbob16hatch]

So i take it your running a open collector? any reason your not looking into running a true divided setup and focusing on manifold design/materials?

on the turbo side of things, just run a big comp wheel in the small housing, it has been done.

[Eville140]

I bet you will have problems with it hitting the valve cover, if it was a bottom mount you probably be okay.  The holset's seem to hang a bit different than garrets.  The turbine housing mounting flange seems to be farther away form the center line of the shaft...if that makes any sense. 
I think you can download the mechanical drawings from the holset website, but it has been a few years since I looked.

not exactly sure how a quick spool valve and a divided manifold will work.  care to post your idea?

You would have to have a wastegate that would open and flow the exhaust over to the other turbine port.

then why not just build a manifold that all feeds one side of the scroll, then have a huge wastegate that did nothing but feed the second scroll.  at a certian psi it would switch over to twin scroll and that would eliminate the quick spool valve that if it is done rhmt style, would probably have it's fair share of issues.  of course it would probably be pretty hard on the single wastegate with that much flow going through it but who knows.  kinda sounds like an interesting idea

Only problem with that idea is feeding the entire engine to one port that is effectively half a .78a/r housing in size. this would kill top end as the gate would never flow enough and efficiently enough to provide good top end flow.

thats why the temporary re-routing of gases in the vacuum and up to boost threshold, then switching to the standard manifold turbine design would provide the flow up top.

Sorry for the thread jack, but this is RHMT.

i understand what you are saying, but isn't the largest wastegate like 50mm?  i think with proper wastegate placement and a big enough wastegate, then it might be feasable. 

anyway, it is just an idea

It defeats the purpose of building a divided manifold, which is FOR quick spool.

[caged]

True, but what would be better a true divided manifold with twin wastegates and a medium sized rear housing. Or an undivided manifold with a quick spool valve and a huge rear housing, you would halve the A/R at low boost and spool up and have the big top end of the big rear housing. From what iv heard those quick spool valves are worth it for the quick spool up. Ill be putting a quick spool valve on my HX35 with an 18.5cm rear in the next month or so on my 1.8L.

[turbob16hatch]

true divided will win everytime. Kinda what it is went to do.

I'm taking an ebay "t3 wastegate adapter" thing, putting it between the turbo & manifold, blocking the WG hole, and adding a flap that acts as a divider when straight, or a diverter when it's angled over to one side. Forget about the WG idea, just imagine it's a 2.5" thick T3 flange.

For those of you who understand the stock 2jz manifold, it's like I've added a valve in the cross-over tube (between the 3rd and 4th cylinders).

Divided manfolds aren't JUST for quick spool. EGT's tend to be lower, less backpressure, less average cylinder pressures (read: less reversion), etc. I know the fallacy in saying "I've done my research", but I'm certain how it will work. On a larger turbine, a divided turbine will spool much faster, not much so on the t3 sizes. Regardless, if there's no difference, I'll simply lock the diverter to the middle so it always stays a divided manfold. I'll still have a 50trim t3/t04e that spools like a 60trim T3...

[onlyflash944]

shit like this make me want to try a hx-50something on a d16
