Hey fellas,

Lately i've noticed a lot of talk of this "20g" turbo on these forums.

Could somebody explain to me what exactly this turbo is?

Whats so good about it? or any info on it.

Just curious to know.

I've done a whole bunch of searches, but couldn't seem to find an explanation.

Thanks in advance!

 

a 20g is a Mitsubishi Heavy Industry turbo that is available in a TD05 (similar to your stock exhaust wheel) or td06 (larger wheel). It flows about 44lbs/min and can make 400hp. In my opinion it's a little too laggy and has to be run externaly gated. it's not a bad turbo but i think that garrett has plenty of more effecient offerings for much less.

I searched real hard and found it about 5 topics down from your post. How many 20g topics do we need in here?

 

Some have made upwards of 450hp. David Buschur of Buschur Raceing is try to mate a 10.5 with the 20G. If it works you will be looking at near or close to stock spool up capable of reaching the 450 hp mark with supporting mods. Sounds promiseing but only time will tell. I dont know who told you that you HAVE to use a external gate, some company's offer it with an internal 34mm flapper for around $100 extra.

 

First, David Buschur has made it clear that the new 20G w/ Titaniuim-Aluminied turbine wheel should spool very close to stock, if not like stock. Secondly, the turbo looks exactly like the stock 16G so there's a huge stealth factor. Even the dealer won't be able to tell that you have a different turbo. Also, the turbo, when it's done, should yield 450whp on pump gas with all the supporting mods done. Throw an alky injection on there and you should be seeing 500whp. The fact that this turbo will spool like stock, look like stock, and at the same time have serious hp potenital makes it a no-brainer for me as far as turbo upgrades go. I have faith in Buschur, he's never done us wrong before.

the 20g is a DSM thing and i is funny that some evo guys dont even know what DSMs are. its the turbo lots of guys get other than the 16G for DSMs. im going to look into a kit when they are out.

in my years of building DSM's i have never seen a td06 20g hit 20psi before 4k, it can and has hit 10's but that is with race gas and amazing tuning. The one that can be made to look like a stock td05 16g is the td05 model which yeilds lesser power.

 

The 20g turbo that Buschur pioneered and hit 10s on many years ago was a clipped TD05H turbine, not a TD06.

 

You're probably right. But maybe the TiAl wheel has something to do with the better spool?

this is the only map i have for the 20g.

i'm not saying it's a bad turbo i just think there are better alternative.

And yes some places do offer an internal gate but i have never once seen one work ok with out spiking or creeping.

 

how much do these go for?


thanks for all ur help btw fellas, much appreciated

 

i could have swore it was a td06h wheel, if it was a 5h then my mistake for the misprint but it would have to be clipped like 10-15 degrees to make that kind of top end ( i know he won't disclose how much of a clip it was) but the clipping also makes spool up longer too.

I am not going to argue that buschurs has done some AMAZING things but that doens't mean everyone else can duplicate it.

 

remeber evos has higher compression better intake manifold, exhaust manifold and head compared to some DSMs so the lag isnt as bad. the evos are set up to run 16Gs not t25s or 14bs like the DSMs

 

hell i don't buy 20g's for less than like 850-900 bucks and that is without the iffy internal wastegate.

 

The traditional DSM version of the BR20g used a TDO5 wheel with a 20 degree clip. My good buddy is running one right now on his 130PSI compression motor and still is getting full boost in the 3500-3800RPM range.
