Hey guys,

I'm planning to get one of these two in a week or so... Just can't decide just yet. Here's the dilemma: I live in Manila, Philippines and I just want some extra oomph from my Evo 5. A friend of mine is offering a TD06-20g for less than half of what it will cost me to get a non BB 50 trim shipped to Manila. I'll be building my own kit with this...

Also, this 20g flows around 640-650cfm's compared to the 16G's 505cfm as I have researched on these pages. If the 50 trim would flow at 49-50 lb/min, and that is like 610-620cfm's would it be logical to get the 20g instead? Mind you, this is a dsm 20g much like what GReddy and TurboTrix is selling and I've seen their reviews on this, especially with you, 4TUN8! haha

Anyway, I am not really rushing to get anything done asap, I just want to be able to have a clear head and not to make little mistakes that might cost me so much cash. The 50 trim I'll be getting is from Precision and it will be journal bearing only as I am trying to build this kit for less that $1000. I am also planning to get some TEIN Super Street Coilovers that's why I'm trying to save every penny! Plus, this car is not raced, but rather "treasured" and kept showroom condition so I am not into those really big turbos, just something to liven up the car...

So if anyone here has a TD06-20G, please give me more info about it, as well as you 50 trim owners! Thanks a lot!

 

The 20g flows less then the 50 trim and is ball bearing as opposed to the 20g's journal bearings.

The 50 trim as you stated is around 48lb/min and the 20g is 44lb/min. Now they will make similar numbers on pump gas +/- 20hp, but on alky and race gas the 50 trim will drag the old journal bearing turbo down the street.

I'm glad that I could help you out in your decision, I understand the price difference for you, so that would make the 20g a viable option IMO. Although if you ever wanted to upgrade turbos you would have to find one flanged in DSM if you went with the 20g. If you went with the 50trim you could bolt any standard t3 flanged turbo up and it would work.

Hope this helps you more.

 

Are you sure 20g only flows 44lbs/min?

I was under the impression the a Evo IX 16g would flow 42-43lbs/min....

 

I recommend the 50-trim. Ben gave detailed reasons, but I want to remind you about the DSM flange. There's a good reason why your friend is offering it so cheap. You won't find many (if any) Evos actually using the TD06-20g, but there are tons and TONS using the 50-trim. It's a better turbo.

 

i have the 20g-9 and love it. the td06 20g has to be that much better.

 

????

No, it's a completely different beast. It's nothing like what you have, and it's a full kit that uses a DSM manifold and everything.

 

i realize its an entirely diffrent turbo. im just saying that the 20g wheel seams to work well even in the stock housing of a 9. I mean if my signifigantly smaller 20g makes 360 whp it would be safe to assume more power the td06 20g

ps he says he is building his own kit in an earlier post. Or do you mean the only mani flange that fits the td06 is a dsm mani?

 

Guys, thank you very much for your help... 4TUN8, thanks for info! I saw his 20g... it was... I totally changed my mind. Fortunately, I found a 50 trim here, just shipped by this dude I know and he's giving it to me for only US$800 for the turbo. That's not BB, but I still find it cheap since the shipping for this pc is about $250 and up to get it here in Manila.

I'm pretty excited with the plans on this thing, I'll have a full repipe with this, together with a really nice custom manifold... I'll be tuning this on a dynapack by next week.

My car is an Evo 5 RS, it's been pretty much stock since day one except for a few bits like the full exhaust, intake, walbro and boost up. Right now, it has 264/272's and I'll be installing the turbo with full repipe and 680cc's. The guys who will be doing the fabrications here are top notch, and they aren't really pricey. It's kinda hard to find people who do great work here, if you find any, chances are they will really rip you off.

I'll be posting what happens, with our extremely hot climate and humidity, I'll be happy to get around 320whp with this thing. My fingers are crossed!

 

I ran both compressor wheels on my 2g, with a TDO6H hotside. I measured 48-49 lbs/min on the 20g, and 49-50 lbs on the 50 trim. These are typical numbers for these very well tested and documented turbos (they've been out forever for DSMs). Both performed very well, but the 20g spooled a little faster. Too close to be concerned about though.

 

kevin, as a reference, doesnt your evo green flow 49 lbs or so per minute?

 

Yes, the highest recored value was 48.9 lbs/min. I'm sure this is where FP and BR got the name from, very similar airflow numbers to those two wheels.
