Why not Tdoh5 20g for a street/dd

[spadepro22]

If there is only minimal spool difference between the e316g and the tdo5h 20g on a street/dd car, why does it seem more people run the e3 16g? Seems to me it will be less load at higher psi on the turbo on a daily basis.

TD05 20g is arguably the best street turbo or our 2.0 platform.

The reason more people run the 16g is because it is bolt on from the factory for our setup. The TD05 20g come with a downward firing compressor cover and a t3 10cm turbine housing. Yes you can adapt it to work, new intercooler piping, machine a 16g compressor cover, use a TD05 bolt on housing (either 6cm or 7cm), but its not as easy as just swapping turbos. Now its not hard to find a way to make the 20g work.

I have run a TD05 20g and lover the sucker. Its a lot of fun as a DD turbo.

I thought I was a good idea, I'm getting a tdo5h 20g turbo built right now. I'll be running it in a couple weeks. Should work just fine.

 

[burkgonzo]

Awesome turbo, just make sure you have the supporting mods done!

I loved my 20g, it was definitely a blast to drive on the street!

Makes sense. Well if your upgrading then this should be a perfect fit right, because you'll already have the turbine housing from the 14b or 16g and assuming you have intercooling piping already too.

I beat myself to death researching weather to upgrade to the e3 16g from the small 16 and researched the piss out if the site for about 10 hours on the 20g today before coming to this conclusion with some help from some tuners.

Why not? At one time Evo III's were $550 new, and 20G's were about double that. Now the playing field is evened.

 

[DSMTyson]

The best street turbo as far as 20Gs go is the 20G with a machined TD05 compressor cover and the TD05H turbine wheel. Also know as the Bastard 20G.

Now if you want a 20G that will produce some serious airflow. Use the TD06 down firing compressor cover, the TD06H4 turbine wheel, and the 8cm DSM flanged turbine housing(if you can find one)

 

[JusMX141]

Another good reason the 20G isn't more popular when new from Mitsu is because it was never offered as a bolt-on upgrade, only with a 10cm T3 turbine housing. Any shop selling a DSM bolt-on 20G regardless of compressor cover or wastegate configuration has had someone's hands on it, and obivously they're not going to swap housings and configure a wastegate for free.

I was told the compressor cover doesn't matter, weather its a tdo6 or tdo5h.

I just picked up a td06h 20g with a ported 8cm bolt on dsm housing.. I cant wait to run this turbo.

 

[J_HEATH]

Buschur 20G, hands down.

 

[TSITurbo95]

A td05h 20g spools as quick as an evo3 as it has tbe same turbine shaft. But by far the best street turbo is the 20g. Spools quick, and hits hard. I had a blast with mine on my old setup. As for the compressor cover, the down firing is more efficient.

 

[spadepro22]

Is there a proven difference in which one workes better between the tdo6 vs the tdo5h compressor housings, or is it just a debt?

The bigger difference is the turbine housing. When you run a 20g in a tdo5h turbine housing, that is where the spool like a 16g comes from. Yet it will still be limited on power (airflow) at the higher rpm range. Then when you switch to the tdo6 housing, you lose the quick spool time and the hard hit in the mid-range. Yet you will seriously increase the turbos efficiency in the higher rpm range. Like stated before the compressor side doesn't carry a huge difference, although the downfiring flows a bit more efficient. But if you wanna "hustle" some guys at the track, put a 16g compressor cover on it, so they don't know the difference.

So to simply answer your question, its just a personal preference or how much time/money you want to put into the build. If the 20g doesn't come with the tdo5 compressor cover you have to find a donor/pay for machine work, ect.

The smaller TD05 compressor housing can be prone to causing surge issues with the 20G's.

That turbo is going to be fun as hell.

I understand the difference in the turbine wheels, and how to set it up in a tdo5h, I was refering to the compressor housing size. So your saying its personal preference.

I ran an e3 16g for a while and loved the way it kicked you in the seat. I picked up a tdo5 20g for cheap so put it on.

It spools up just as quick as the 16g but does not hit as hard. However it just keeps pulling harder and harder all the way up to redline.

Both very good turbos but I like the 20g better.

Or you can build it with a TD06SL2 turbine wheel. Nearly as small as a TD05H turbine for fast spool but with one less blade for more top-end flow. That is what I used for mine along with a billet compressor wheel. The smaller size of theTD06SL2 also allowed me to use an Evo III style 7cm housing whereas a standard TD06H turbine wheel would be too big for that casting.

The center section is a genuine MHI w/ HD thrust bearing. The rest is from Kanugawa out of Taiwan.

This is the biggest reason for a TD06 compressor housing. A bonus would be that no J pipe is needed.

 

[pneumo]

I have a 20G on my car right now and it's a blast! I like the quick spool and top end power.

Now that the price of a 16G is about the same as a 20G there's very little reason to choose a 16G. The downfiring compressor cover fits better with the pipes in most FMIC kits anyway, no need for a J pipe.

What kind of spool time, top end and hp are you getting with this turbo?

 

[Steve93Talon]

The 20g is still my favorite street/strip turbo for a DSM. I've played with multiple configurations, and I was never impressed with the TD05H compressor housing on it. Definitely seemed choked up compared to the downfiring housing. I've also run a clipped TD05H turbine wheel in a 7cm housing back to back with a TD06H wheel in a BEP housing, they both spooled and "hit" about the same, but the 06H setup definitely pulled a bit more up top. I'm currently putting together a 20g FWD auto setup for a friend, should be interesting.

 

[xxNocturnalxx]

Im loving my 20g, nice power at low boost, haven't turned it up yet but it made 286whp@13psi. Very steetable

 

[Sirnixalot]

My bastard Evo X 20g is a great turbo for daily driving.

so fair i have 290whp & 289wtq on virtual dyno at 16psi. clutch too a dump so that's as far as i have gotten.
