Tough choice, but from what I've learn, at 19 psi you'll probably be making the same amount of power on both turbos. The 50 trim will probably shine at higher boost on pump.
Is the TD06 a 50 trim? I know the Green is, but I wasnt sure about the TD06 20G. What trim is the TD05?

Thanks,
Nathan
 
I dont think there has ever been a back to back test on a dsm that i know of. but a few months back fp built a tdo5h/20g turbo for a subaru, then fp built a tdo6h/20g for the car. the 6h wheel was the clear winner . car made like 25-30 more whp both on pump and race fuel.

fastest 6h = 145mph curt brown
fastest 5h = 130mph john sheppard

if the times page doesnt reflect the 6h/20 as a better turbo its prolly cuz there are 50 5h/20s built for every 1 6h/20

But what was the clip on the TD05H? If it werent around the 20* clip range, its not an equal/fair comparison.

This thread from NABR helps explain some things.

The Green is a T04E 50 trim with a tdo6h hotside. The usual 20G comes in either tdo5h/tdo6/tdo6h hotside. Obviously the Green is bigger than or equal to the 20G on hot and cold sides. The debate on the 20G is the spool vs top end on the clipped 5h wheel and the 6/6h wheels. At 19psi both these turbos and their combinations should give you similar power. Once you start boosting higher exhaust back pressure and efficiency will come into play. You should consider what your goals are and go with that. All these turbos has been proven to produce a good amount of power so you can't go wrong with either, although the 50 trim is known as the pump gas king.

I wasnt looking at the td06h.....but thanks for the info though.

However, now I am kinda wondering is my 190lph fuel pump will be enough to carry the td06 20g or the green. Is a 190 good enough to push enough fuel for 19-22 lbs? If not, then I am not going to bother getting the green, and will simply get the TD06.

Thanks,
Nathan

I have a rewired 190 and have run 29 psi on the 20g without knock or signs of running out of fuel. This was on 117 racegas too. ;)

Sweet. I really didnt want to change that out again. I cant stand the gas smell in the car hanging around for 2 weeks.

Right now I am leaning towards the TD06 20G, but we will see if more people chime in to voice their opinions.

Thanks again,
Nathan
 
The reason I leaned towards a 20g was because I already had a 16g in my car. The cost of upgrading my 16g to 20g was more than $500 less than buying a green. Now I know that the green makes more power, but looking at the fastest times list I see that 20g and fp green's are in the same vicinity of times, with the fastest 20g actually having a faster time (barely) than the fastest green. This to me supports Buschur's statement that the 20g is the biggest turbo any STREET driven car will ever need. I would suggest that anyone shopping for a bigger turbo that already happens to have a 16g consider having it upgraded to 20g for less money than buying a new turbo. I happened to come across my 20g from a local DSM trader ad for $650 with only 3k on it. I then got $300 for my 16g, so I consider that to be quite a bargain!!
 
A local made 370whp on td06 20g and stock intake mani.

Green has made 430whp in dre's car and sk0t grays (with liebels tuning the EMS) @~26psi from what I can recall.

Approaching 400whp you're getting close to the limits of a stock 7 bolt.

I think the big issue is pump gas vs. race gas. Most of the 11 sec 1/4 times out of any type of 20g were on race gas, while a green has gone 11.5@119 on 93 octane.

IMO, if you're a pump gas whore go with the green, but if you prefer better spool for daily and pumping in some race gas for racing like a real man, go with a 20g.

Damn dude, why do I have to be a whore?
I dont use race gas that often because I drive a whole lot and dont feel like spending the extra money. But thank you for your comments.

A local DSMer was using this TD06H-20g before me and he was running 25 psi daily on pump with no knock. Let me say the car was totally badass but it's not something I want to do with my car on an everyday basis. :p
 
The TD06H/8cm/50 trim Green I had in my Eclipse pulled very nicely at 20 psi. Unfortunately I got rid of the car (but kept the Green) before I could turn it up any higher. If I were to go back on my Green purchase the only thing I'd change is to go to a 7cm exhaust housing. The 8cm spools up somewhat slower than the 7cm, and I've heard from many reputable sources that the 7cm housing with the TD06H wheel in it really isn't that much of a restriction at higher boost/RPM levels. In the end I'm VERY happy with the Green and can't wait to get it on a Mirage hatch over the winter. If I were to go with a 20G it'd definitely be a Buschur. SBR may be a bit cheaper, but how can you argue with the success and power that their turbo has had? Just my $.02...:cool:
 
excellent points being said. please continue with this discussion. i too am looking b/w a 20g 5 vs. 20g 6 and green.

one question i have is, it seems a 20g 5 is more better spool wise while a 20g 6 is better up top.

now how much of a spool difference is there b/w either turbo?

i'd be using the 20g on a daily driver with occasional track time and look to run no more than low 12s kissing 11s. ive driven a FWD tsi with a buschur 20g and omg that was scary..haha.

id opt not to clip the 20g if i got it from SBR. im not looking to walk down supras. lol Pump gas is the ONLY option as im one to have my good friend help tune and just leave the settings after im done.

but anyway, not trying to jack your thread, just want more points and what not to be tossed out.
 
a good friend of mine has a td06-20g and i run the green (7cm). his name is 64/2k (he's on this board) and has put down 391 hp on race gas and 24-25 psi.

my turbo is obviously capable of the same, however, i have not been able to duplicate his numbers yet. my best whp to date is 365 @ 19 psi on a mix of 110/91 octane. i tried to turn it up but the car kept breaking up on the top end....thats another story though.... we have a dyno available pretty much any time we need it, so we'll both be back soon....

first off, if your interested in a 20g and worried about price, get a td06 hands down. however, if i could have ANY 20g it would be buschur's....its just as proven as the green. the price, however, is just too much in my opinion.

jason's 20g gets full boost around 36-3700 rpm, and my green hits 19 psi by around 3900.

hope this helps...

thanks for the reply...

made up my mind, tdo6 20g from slowboy more than likely or fp...spoke to rob and his said for my goals that a 20g 6 and a green would have a little difference at the psi level i would be running my car at...pz
 
91eclipsegsx16boy , are you talking about mike running the 11.50 on the green? cause i just got off the fone with him not too long ago and he went 11.50 on a pump gas green w/ stock bottom end and still shut it down the last bit of the track due to head problems (ie pushing antifreeze @ around 7k+ in 4th) I know for a fact that he could go 11.40's w/ ease, and probaly get 11.30's w/ some skill :p


P.S. mike, if you are reading this, i hope i got everything right (i know i did, but just in case)

P.S.s. here is the link to his webpage http://www.hometown.aol.com/myeclipseruns11s/ just to show you what limited parts and some good tuning can do with a stock bottom end. BTW, ill catch you as soon as i get out of school :santa:
 
if u guys dont mind id like to throw in the pte 50 trim turbo to be compared to these 20g and greens. extremepsi.com has them with internal gate, which im a fan of keeping for sure, with install kit shipped for 999. sounds like a good deal to me. what u think?
