14b in evo3 turbine housing?

[eric91gst]

I currently am trying to have my e316g turbo rebuilt. In the meantime, I have a 14b laying around. I would much rather use the evo3's turbine housing because it is much larger than the 14b's. Will this be able to work? Im assuming so, considering both turbos are TD05H. Am I right?
-thanks

You will probably loose "compression" on the turbo because the housing is not optimized for the blade pattern and size... I believe.

The turbine blades are the same for both turbos.

ok thanks a lot. BTW, has anyone actaully done this before and have you noticed any performance gains due to the larger housing creating more air flow?
-thanks

I think you will loose air flow because of a larger compressor housing.

 

[eric91gst]

I think you will loose air flow because of a larger compressor housing.

-How would you loose airflow? Theres more room for air to flow. You must be thinking about lag. It makes sense that a bigger turbine housing will cause for a little longer spool-up time but not a lose of airflow. Not to disrespect, but the compressor housing isnt what I was talking about. I was talking about the turbine housing. The compressor housing and turbine housing are completely different things.

I think you will loose air flow because of a larger compressor housing.

The compressor side is not in question here and is not going to be changed. Also, I believe that the exact opposite will occur, airflow will increase.

Eric,
The turbine housing change shouldn't change much about the general shape of the 14b compressor map, but it may shift the whole thing towards higher flow numbers. I think that this may work well. It should still spool quicker than an E3, but not have as much flow available as an E3. I am interested to see how this works if you try it. If you have good results, please let me know, I've thought about doing this to mine for awhile.

 

[eric91gst]

ok so I guess that answers my question that it will work and is possible right? But what your saying, the real question is will it work well?

 

[delta448]

Right. -I would imagine if it worked very well, that it would be a more popular and more oft discussed mod.

 

[eric91gst]

well the main reason I want to do this is that the 14b turbine housing that I had was cracked a little bit around the wastegate hole and flapper. I didnt want to take the chance of hooking everything back up and having it suck. Thats why I just wanted to swap in the E3 turbine housing in the meantime that I am having it rebuilt and buy all my supporting mods.

Yes, the 7cm housing will work. I have done it many times before. Everyones car is different, but we noticed the car felt a little better at higher RPM than with the small 5cm turbine housings. The EVO III unit doesn't seem to act as much like a cork at higher RPM.

I have recently come across one vendor that sells something similar - an Evo III 16G housing with a 20G center housing (aka rotating assembly). You can find it (and purchase it) at the link below:





Scroll down until you read "20G enhanced EVO3 TD05H"




However, their price is damn expensive, at $1400.00.

 

[eric91gst]

cool, anyone else like to comment on the effects of doing this that have done this before? It would be much appreciated.
-thanks

 

[eric91gst]

anyone else?

Blablabla ....
Yes It Will Work And You Wont Loose Anything
I Ran 12.27@ 111mph On A 14b In A Evo 3 Housing

It's an upgrade for the 14b as it flows better. Look on dsmtimes.org and see the 2nd fastest 14b car (in the 11's) uses the 7 cm housing.

 

[eric91gst]

thanks guys

I have a 14b with a swapped ported 7cm housing. The difference is very noticeable! The turbo hits full boost around 300 RPM lower than the 6cm housing. It is much more responsive too.

-what about results from an unported 7cm housing?

 

[Aphix]

Good to know I'm not the only one. I just picked up a rebuilt 14b with a 16g turbine housing for 120. Its ready to go in I'm just waiting for some warmer weather so I'm not stranded with my daily driver freezing. I feel alot better about the purchase from what I've heard now! I'd also like to know if anybody else has results from doing this?

14b with a 6cm, then switched to a 7cm. Made a quick spooling turbo into a gutless one, added 400 rpm worth of lag. I was running an automatic at the time and couldn't wait to switch back. All the lag of a 16g without the topend, didn't see the point and probably the mod I hated the most. Its been 12-13 years since I tried it, still remember how much I hated it. Immediately I slapped a clipped small 16g/7cm into the same setup and that felt better cause of the bigger compressor. YMMV.

 

[FonZ454]

I noticed more topend going from a very ported 6cm to a stock 7cm. I can't recall any boost diference though.

 

[fwdmaster]

I'm running the same setup, topend increased,turbo spooled up quicker also

Wow!! Talk about price markup. SBR the maker of that turbo only sells it for just a tad over $800.
