14b into a 20g...hmmm

[pickens]

I just wanted to pick somebodies brain. I know a 14b is turned into a 16g by just switching the compressor wheel, housing, and backplate. But, is it possible to do the same thing and turn the 14b into a 20g. I believe they use the same center sections and hot sides, so I would assume that the cold side bolts in place without much effort. Any comments?

 

[project94tsi]

i dont know but that would be a nice cheap way to get a 20g sounds resonable but im not sure.

First of all, turning a 14b into a 16g isn't a cheap proposition to begin with.

Howeverm if you wanted to, you could:

Install a 20g wheel and backing plate, and stuff it inside a VERY ported TDO5H compressor housing.

Then, buy a 7cm turbine housing, and clip the crap out of the stock (TDO5H) turbine wheel.

Of course, then you have something like 500 dollars in work done to a turbo that cost you at least 100 dollars, leaving you with a 600 dollar piece with crappy old stock bearings. Spend the extra money and just buy a new one. If you really feel like not sucking, go TDO6H.

just an idea

Well, I bought a td06-17c turbo two months ago to do the exact same thing! I wanted to stuff a 20g wheel inside but the price of just the wheel ($180 from FP) stopped me from doing it. My turbo comes with a td06 turbine wheel and a td06 comp. cover so that would not be too far from a "real" 20g. Is there any place that sells Mitsubishi turbo parts cheaper?

buschur 20g's are tdo5h and they are far from sucking.

BR uses a 20g with a VERY clipped TDO5H turbine wheel. That is a much less effective and less efficient way to do it, than simply sizing the turbine properly.

I've seen HUGE numbers come out of TDO6H 20g's on very mild setups.

they sell compressor wheels here http://www.mjmturbos.com/CarTurboDescription.html , i have a spare 20g and i tried to get in contact with them but the email dont seem to work

 

[monotalonawd]

ITSME4G63, seeing that you have a spare 20g, don't you have any parts out of it that you would like to sell... like a 20g comp. wheel?

oh shit, sorry I meant I have a spare 14b that I wanted to turn into a 20g, sorry for the mixup I guess i was in a hurry when typing the shit.

I guess Tym's 10.9x run on his less efficient BR20g was just a fluke!

Would you like to tell me where I said that the TDO5H 20g wasn't capable of 10's, or wasn't capable of making power?

You might as well not bother, because I didn't.

The fact of the matter is, the TDO6H 20g is just capable of making MORE power and going FASTER than the TDO5H version is, and from an engineering point of view it is also a better design.

Just because something works, doesn't mean it is optimal.

Buschur went 7's on a GM Powerglide 2 speed transmission. I still don't see too many people putting them to use...

See my point?

 

[ibanezeros]

Does anyone know if a 20g wheel is tapered on the back? like the 16g or not?

 

[GPTourer]

Isn't this the same idea as FP's sleeper 16G? 20G internals stuffed inside a TD05H housing?

Yeah, and they try to keep that shit a secret, like nobody knows what in it :laugh:

I'm also wondering this myself.

I have a 14B which is on my car now, but i bought a small 16G that was blown.
I rebuilt the 16G, but since it's not balanced, I was going to get a td06 comp housing and 20G wheel and put it on the center.
That costs too much, So i was wondering if there is ANY way the 20G comp wheel can fit in the comp housing from my 16G? I have acess to a complete machine shop so i can machine the housing if needed.

I was told that the 20G wheel will in No way fit the td05 16G compressor housing. Is that what's in a sleeper 16G?

If a 20G wheel won't fit in a 16G housing, than what about an 18G wheel?
Does the 18G/16G/20G use the same backing plate?

Also, Is there any production vehicle like heavy industries trucks that come with a Td06 turbo that i can steal the compressor housing off of?

If there's a motor that i can steal the Td06 comp housing off of, then i'll go the 20G route, but If i'm stuck with my td05 compressor housing, Which is the best option for me? 20G or 18G comp wheel?

You might try finding specs on Mitsubishi-Fuso turbodiesel trucks for looting spare turbo parts. Other then that, Mitsubishis turbos are in use in dozens of OEM applications. Maybe Hino, Isuzu or Volvo used them too.

As much as FP charges for the sleeper and as secretive as they are about it, I doubt its something that's easy to do and get "right" Maybe you'd be better off using 18G parts.

 

[ITSME4G63]

Maybe you'd be better off using 18G parts.

or send it to forced performance and have them turn it into an 18g for you :laugh:

 

[pinknuggit]

ah Ha!

I'm off to the salvage yards in search of a fuso FH.

 

[ibanezeros]

18g's and 20g's are tappered in the back, but if you buy the rebuild kit for the approraite compressor wheel i'm pretty sure it comes with the right backing plate

Umm, CRAPLOADS of people use PG's, not in DSM's but in TONS of GM cars.

Most mitsu trucks(FUSO) use the TD06 compressor cover, older trucks have a black plate on the cover and newer trucks have a red plate on the cover. Most of these covers though are originally built for 14a or similar compressor sizes so there is some porting to do to fit a regular size wheel there. Anyway....
My question is the following, I currently have a built TD05 turbo with a 17C compressor wheel fit in a thoroughly ported original 14B compressor housing. I have access for free to the above mentioned compressor covers(housings), meaning the fuso covers that are used on the 20g style turbos. These covers are easy to fit on the TD05 cartridge with some port work, the thing is that being somewhat larger(in diameter size) than the original TD05-14B compressor cover, what would be the gains (performance wise) of swapping the TD-05 cover for the TD-06 compressor cover. I assume it flows more air but will I notice a difference from just the swap of compressor housings???
Please dont tell me to go buy another turbo, it's only a technical question considering that these mods would cost me zero money!!!
Thanx

Well since we are on a DSM site I would imagine thats what we are talking about.

The point he was making is that a TD06 20G WILL make more power than a TD05. I hate when people say "John Doe went 12's on a 14b so there, they dont suck". So what if someone went fast on it. Does that mean they couldnt go faster with a TD06 20G?
