20g turbo

[97_eclipse_gst]

I have been looking for a new turbo for the past few months and i just about have enough money. I have been looking at the evo 3 16g and it seems really goood but its max power is around or below 400hp. Now my friend has a 20g and is about to upgrade his turbo. I can buy his for 800 and it only has around a 1000 miles on it. I looked in the past threads and couldnt find anything and ijust want to know what i would need or change to fit the bigger turbo. I have all of the supporting mods and i am about to get dsmlink. But would i have to change any oil lines or anything for it to work properly, because i know it is an exact bolt on but there are always small problems that will get in the way. Also if anyone knows how much slower the spool time is from the 20g to the evo 3 16g. Thanks for any input

This is not from personal experience, however I have been researching 20gs/50trims/gt30rs gt30s blah blah blah etc.


The thing you have to keep in mind is that 20gs come in several different flavors.

For a turbine wheel you have a clipped or unclipped TDO5, clipped or uncliped TDO6 or (you really wouldn't want to clip) the TD06H

The exhaust housing can be 7cm 8cm or sometimes larger (rarely)

The compressor cover is a TD06 with a TD06 20g compressor wheel (hence the name 20g)

Similar to how a garret turbo can be made, a "50 trim" is a 50trim compressor wheel in a T04 E/S/ housing with a T3 turbine housing and a .48/.63 A/R (sometimes called stage3 stage 5 etc)

From what I've read, the 7cm housing with a TD05 wheel is the fastest spooling and is basically a 16g spool speed. However the exhaust side is restrictive so clipping/porting is very beneficial. Typicaly figure less than 500 rpm slower than an evo316g

Step up to a 8cm housing and TD06 wheel and you add maybe another 500 rpm max.

Figure out what your buddy has exactly, and then make the decision from there Realize that 660s will not cut it on a 20g that is "maxxed out".

Spool time is almost exactly the same. The EVO III has already surpassed the 400 WHP mark. Yes, this is from personal experience.

$800 for a used 20g seems kinda steep. You could buy a brand new E316G for around $550. You could even buy a Bullseye 50-trim for like $700. Like drivemusicnow said, find out exactly what kind of 20g it is.

20g's are old school, For $800 now a days you can find something alot better. I am not putting down the 20g, So no one needs to come in here bashing. I am just saying for that amount of money, You have alot more options, On a brand new turbo.......

That may be true, but 20g are the ultimate as far as proven performance. Look at the DSMtimes list. dozens of 20gs in the 11s and 10s. really not too many 50 trims.

if you're looking for 400 awhp, I think a TD06/TD06 20g is a good option. (7cm with clipping, 8cm housing without)

That said, I'm having a tough time deciding between a 20g setup and a t3 50trim setup.

Amen. I agree 1000%. The beauty of the 20G is that it hits like a ton of bricks. Use it on an AWD stroker and you'll have an exceptionally potent street car. Besides, off the shelf, no one makes a turbo as good as Mitsu. I've beaten the living piss out of my 16G for the past year at sustained boost levels of 26-28psi and it still has no shaft play. I'd go TD06 20G in a heartbeat.

Mitsubishi turbos are better than FP turbos?? I thought the FP Green was a better turbo than a 20G.

It depends on what you are refering to when you say better. I say butts are better than boobs, but that may be different for someone else.

I chose a 20G for reliablitly and it is easily one of the most documented performers in the turbo world. I KNOW it will go low 12's high 11's with out breaking a sweat in a full weight DSM. On top of that becasue Mitsu turbo's are made for cars, or trucks in this case, that drive a ton miles it will be all kinds of reliable. Will it go as fast as some other turbo's that are larger and newer, no but that is a given. Again it depends on what flavor of 20G you have but what I said above still remains true.

Whats the difference between the tdo6 and tdo6h thanks

The 6H turbine wheel is larger the the 6. The FP Green is a Mitsu hybrid turbo. It starts with the Mitsu turbine housing (7 or 8 cm), center section & 6h turbine wheel then they bolt up a garrett comp wheel & cover. They also add a heavy duty thrust bearing and some other goodies. So as far as reliability goes they should basically the same.

In comparison, I've driven a friend's car which previously had a FP Ported Big 16G installed, but has now been upgraded to a 20G. The 20G spools a bit slower and doesn't have the "rear-ended-by-a-Mack" feel that his old 16G had, but once it spools it pulls HARD to near redline. Tuning has been a lot more crucial on the 20G, also. It was pretty much a bolt-on swap except new slim cooling fans had to be installed to clear the location of the wastegate actuator on the 20G. Regardless, I'd buy one without hesitation. Bargain a little more with your buddy; $800 seems a little steep for a used 20G, even if it has very low miles.

Remember, I said "off the shelf". The Green is a hand built Mitsu-Garret hybrid and is an amazing piece of equipment as is anything FP builds. The flow is equivalent to 50 trim territory and if I could afford one, I'd grab it, but a 20G is more in range.

See what I mean?

 

[v2ner]

Both the Green and the "classic" 20G have proven themselves. I've had good luck with the both of them. It's been 3 years now and the 20G is still runnin strong. I sold the Green...only to go big. At 27psi the Green pulled more and yes, spoolup on the Green was a bit slower than the 20G but not much at all. Both are excellent choices but not for $800 used.
