yo,

went to put on my hybrid turbo i built out of a ebay-china t04e compressor housing and its not even close to fitting or clearing the LIM. what are your experiences with hybrid turbos and what are the compressor housings diameters? does it not fit because its a T04e compressor housing or because its an ebay compressor. I'll post up pics tomorrow morning. If you've got any pictures of the clearance between your LIM and hybrid turbo lemmie see them please.

PS the set up is a S5 exhaust manifold and turbine housing and a s4 lower intake on a JDM engine. could the mix match of s5 manifold and s4 LIM f'd me up?


Thanks!

 

It may be because of the compressor housing. I know a T04B compressor housing is a tight fit. So going with something even a tad bit larger will give you fitment issues. Have you thought about getting an engine flange to space it out a little bit?

 

Its not the lim or exhaust manifold. The stock turbo is tucked pretty tight to the engine and thus there simply isn't much space to be had. A T04e is on the large end of what most people would run for a hybrid anyway. One reason is because it starts to get out of balance (assuming you didn't change the turbine wheel) the other being the space issue you are currently encountering. Hope it all works out.

Edit: even some of the bnr hybrid compressor housings need to be clearanced to fit and I don't even think the stg 4 uses a to4e iirc.

 

as far as I know, BNR uses to4b compressor housing.
It is a really close fit between the housing and LIM.
Its almost touching theres about 3-4 mm of space between them for me.
I got a stage 4 BNR

 

Yea, that's what I was using as reference. I had a Stage 4 BNR that's built with a T04B compressor housing and it's about 3mm from the LIM. So I can definitely see a T04E compressor housing having fitment issues without spacing it out.

 

Mine is a to4b compressor housing , I trial fitted mine and clearanced it while my motor was out/before tearing it apart.


Trim the ear down on the upper right of this picture

 

So i'm guessing the measurements are different across the backing plate and comp housing. i was frustrated did some major grinding and still no luck.

I used the T04e wheel and housing.

my friends that were helping me suggested a spacer but, that would mean i would have to modify almost all the lines and the exhaust would probably need to be modified to bolt back up together too.

anybody have a t04b housing laying around they can take a quick measurement off so i can compare it to my T04e

and then are they're any identifying marks on the compressor housing to tell its a t04b, i'm going to order one on as soon as i can be sure that it has the correct housing.

untill then stock turbo is going back on and engine is going back in.

 

Turbine wheel?

 

stock hotside and wheel

 

I had fitment issues with the hybrid I built fitting and grind down an ear. Before I ended up putting it on I tried clocking it to a different position and it went on perfectly. It changed the actuators position a bit but it still worked and is still working perfect to this day. I don't know if mine was a to4b but the aqr. was 60 and it was from a XS Power turbo.

 

I dont think a to4e housing will fit if u are using the stock manifol. The, placement is just too tight. Unless you are adventurous with your grinding of the housing. You might have to take a lot off. I mean thr to4e kit which I think hks or greddy had for the fc came with a manifold that extended the turbo out further if I remember.

 

Just to add...

From what I've read, the dimensions of the T04E housings won't work with the stock exhaust manifold. That's why you see T04B housings on most hybrids.

If you have a T04E wheel in there, you've got a T04E housing.

 

T04E backplate dimensions are 6.11" diameter vrs. 5.24" on the T04B. Even the T04S compressor housing has a smaller backplate diameter then the E at 5.75". No surprise T04E's are bulky compared to the B's.

 

I've got a .60 trim To4E hybrid and tubular manifold for sale that will fit the stock intake. PM if interested.

 

yeah, i'm just going to have to brake down and get another compressor and wheel, then rebuild my hybrid. i took alot off the compressor housing and some off of the intake to try and make it fit, but no luck at all. still ended up with near a 1/8th inch gap at the top of the exhaust manifold outlet.

 

just some observation, but it looks like the t04b has the ID casting boss under the outlet of the turbo (left hand when facing the inlet of turbo) and the t04e has it on the opposite. i've also found some ebay turbos unlabeled as what compressor housing they are but have that ID boss in the "t04b's" side. more research is nessisary...

I thought for a bolt on stock hybrid using TII lower intake manifold you had to use the

Turbobetics TO4B HiFi compressor housing

which is smaller than the regular T04B housing but offers 90% of the flow.

 

I assume you just use whatever one that will fit. My 1st try I used a ebay t3/t4 honda T70 turbo from craigslist. The front was HUGE and wouldn't clear anything lol. This second go around I made sure to get the fitment close if not dead on. I was pretty much still guessing though, but I nailed it. Mine is a to4b housing with a v-trim wheel.

that looks like a knock off t04b

 

It does, if only they actually had any information about the compressor wheel.....

And judging by their other listings I'm not sure they can be trusted, they list turbos as to4b then state that the compressor exducer (which they call "mayor") is 3" wtf?

 

this looks good, one of you guys should jump on it. Looks alot similar to mine.

 

I 'm local so no shipping! don't drive up the price for me.

 

I think that is the T04S housing they reference to as the T04B 0.6a/r housing flows to.
I've seen some of the BNR hybrids with actual 0.7 a/r T04B housings. Anybody know what trucks /garrett part no.s these are? I'm guessing these are of some truck app. that uses an "H-trim " compressor wheel,as I think I recall seeing one briefly on fleebay once...would like to acquire one of those.

 

I was wondering the same thing, they must be industrial applications because all the f-350 and dodge 3500 stuff is too small. I gave up as I was never able to find a comprehensive resource for this information. Plus I'm not going to find whatever comes with that turbo in my local junk yard anyway.
