14b/16g

[GsXdSmKingGsX]

I found a 16g housing that is in good condition and got to thinking if i could possibly make a hybrid turbo.

I found some good 14b internals and stuff and was wondering if anybody has ever done this and/or if it works well.

 

[gofer]

all tdo5 turbo's have the same turbine wheel, its just the comressor wheel that varies between them. im not sure what housing your talking about (exhaust/compressor) but if its the exhaust side then its the same as your 14b. if its a 16g compressor housing then yes you can attach it to the 14b's CHRA but you won't see any gain's and there will be a noticeable GAP between the blades and the inlet of the turbo. To do it right you need to get a small, big, or evo III compressor wheel (depending on what size the housing is) as well to make it work to your advantage

Acutally the turbine housing on the 16g is a 7cm^2 housing rather than a 6cm^2 from the 14b. If you are referring to the hotside, you can swap it. It will spool a bit later, and flow a bit better at high boost/rpm.

 

[dsm-onster]

Yes, the turbine housing of the 14b is smaller than the 16g. But the wheels are the same. As alluded this means a little more lag but more flow and consequently horsepower per psi. The 14b compressor flow 34lb/min. Which is an impressive number considering it's size and considering how plentiful they are. But you really need a better flowing turbine to exploit that potential. Which what the 7cm^2 16g turbine housing can give. The slight differens in spool speed is worth it.

 

[GsXdSmKingGsX]

So your saying its not the smartest idea? im not trying to run more than 15 psi of boost so i thought this might work for that

 

[habitatguy187]

At 15psi you should probably just stay with a regular 14b.

 

[dsm-onster]

So your saying its not the smartest idea? im not trying to run more than 15 psi of boost so i thought this might work for that

No I said the increased flow of the 16g turbine housign you have is worth the lag, since the 14b compressor has plenty of flow potential, something that is difficult to see with the stock 14b turbine housing. You could see gains even at 15psi. But at least you'll know that if you crank the boost to 20 you'll have PLENTY of turbine to max out the compressor flow and see upwards of 33-34lb/min. More than enough for 300whp.

 

[GsXdSmKingGsX]

So you think its good for more than 300 whp? I didnt expect that

 

[dsm-onster]

You will have a complete 16g turbine (wheel and housing) that flows well enough to have seen 400whp. And you will have a 34lb/min compressor (the 14b compressor). It's definately something that can happen. And not with GOBS of boost. It can do what any 16g can do up to its compressor choke, which is enough for over 300whp.

 

[gofer]

so now ive got a question because im completely confused...
a 14b compressor wheel can only push "X" amount of air how is it possible to increase its effeciency by putting on a bigger compressor housing, the wheel doesn't change. Im just asking because ive got a busted up evoIII CHRA but have a perfectly fine evoIII compressor housing and at the moment im running a small 16g. it just makes no sense how the same sized wheel will push more air with a bigger housing around it... please explain more dsm-onster. does the compressor housing rated for that wheel just not allow the wheel to flow air to its max potential?

 

[dsm-onster]

We're talking about putting a larger turbine housing on the 14b. The 14b comes stock with the 6cm^2 turbine housing. The OP is wishing to upgrade to the 7cm^2 16g turbine housing. Which is possible and somewhat common. The 14b and the 16g share the same td05h turbine wheel.

The 14b and 16g share the same td05 compressor cover. There is a difference in the inlet bore and they housing is cut for different compressor wheel. Due to the later, you cannot just install a 16g cover onto a 14b turbo. Nor should you bother, since the a/r and volute orientation is the same. It would not be an upgrade. As well, upgrading compressor covers generally provide minimal increases in performance and usually going to a different cover is done to deter surge. Something of which a 14b has no issue. You CAN gain a broader map, increasing the choke flow slightly by using a larger compressor cover. But this usually comes with a sacrefice of lower efficiency. Big 16g compressor wheel in the td06 compressor cover and in the td05 compressor cover.

The 14b compressor wheel in the stock 14b/16g compressor housing flows 34lb/min in typical ambient conditions. But squeezing that flow through the 6cm^2 td05h hotside would be a difficult feat. Possible I suppose. But the small difference in lag going to the larger turbine housing is worth seeing that 34lb/min airflow at a lower, less knock happy boost, with less backpressure to heat the combustion chamber.

You got me all excited now!!!

 

[habitatguy187]

I'll be putting mine on this weekend hopefully, I'll be sure to let everyone know how it feels.

 

[DSMunknown]

Now I definitely have to do a log and go on the dyno. Pushing my 14B to 22-23PSI now but it doesn't seem that I've gained ~100whp from my 192whp with my T25 setup @ 15-16PSI. Guess we'll have to wait-n-see.

 

[toofast82]

I switched my exhaust housing to a 7cm I had on my 14b. It made a noticeable topend increase and you can't really notice the extra lag

Yes please do!

Thats what i like to hear

Yeah the t25 just isnt cutting it for me. You should do what im doing

 

[dsm-onster]

Yea, the 14b compressor flows 100whp more than the t25 MAYBE. . . (Afterall the t25 compressor flows 27lb/min and the issue is the terrible garrett turbine wheel, which is often terrible with many other turbos). But you'll never see it. . .well you CAN see it. . . but not likely, unless you make a 16g out of the hotside. It's a proven combo. Just enough flow to merit the lag, just enough lag to merrit the flow. Give a 14b compressor a chance

 

[DSMunknown]

Thanks for the suggestion, pal. But I'm way ahead of ya. Been posting ads for blown E316Gs or Evo 3 turbine housings for months now. May end up getting FP's Evo 3 Turbine Housing. Would like to see the difference between that and OEM. Supposedly they've altered theirs slightly.

 

[dsm-onster]

Supposedly the only difference is the metal content. If there's a different a/r or a different inlet shape to the turbine blades, then CB's results are down the drain.

 

[GsXdSmKingGsX]

Really? Thats pretty sweet

A little late and off topic but I found this housing...

DSM ECLIPSE 16G TD05H 7MC2 TURBINE HOUSING TURBO:eBay Motors (item 150342848485 end time May-31-09 18:54:15 PDT)

I'm wondering if it can be trusted to be what they say it is or if I should just shop around for a used one on here or perhaps get the FP one. I'm thinking that for the price it might be worth it for somebody to try and see how it works out. If nobody goes for it by the time I reach that step in my dsm journey I will probably try it out just to see how it works and post my findings. Just though I would put that out there in case any of you were looking for the housing still.

Yes it is perfectly fine. I just picked up my friends 18g from his GReddy kit off his civic since he got a GT30. I had to order that and it works perfectly. Another member on here also did the same thing. You might have to open the wastegate hole a bit with a drill bit to make it fit on the housing but thats not a problem. Remember, it's just the housing...its not like it has the chinabay seals and crap in it.

 

[GsXdSmKingGsX]

Thats actually the housing that i have

 

[habitatguy187]

Looks like I'm not going to get mine on this weekend, ran into another problem (with a 17yr old modded car? No way)

I'll try and shoot for next weekend, but who knows.



EDIT: BTW I picked mine up for $20 shipped with two broken studs. I know this is insanely cheap (stamp said it was $15.05 to ship) but I just posted a WTB ad and lots of people have blown 16Gs that they'll gladly sell the housing on.

 

[DSMunknown]

Saw that eBay exhaust housing a while ago. Just not too confident at this time regarding its durability. Don't want my turbine housing to blow to bits when I'm doing a pull (or any other time, for that matter).

On the other hand, $75 compared to ~$300 is a little tempting. Perhaps a smart idea would be to have an extra 14B lying around just in case things get nasty. As they used to say "An heir and a spare".
