Well I spoke to couple places and turbochargers.com sells the TME turbo for $699, but is turbochargers.com a trust worthy place to buy stuff? I heard a few horror stories about them.

 

On a new turbo, sure... a rebuilt? that's where I've heard the horror stories...

 

How about Blouch Turbos?

 

I just don't want to order TME turbo from them, get like TME 20G turbo whatever you want to call them, because $699 is pretty cheap for a TME.

 

Short summary. If you like the White Rabbit Evo 8 version, you will love it in an Evo 9 version. The Evo 8 WR was always built with the Ti/Al wheel as was the TME. The WR Evo 9 turbo with the Ti/Al shaft spools as fast as a TME, in my testing at least. And the WR Evo 9 at high boost pressures makes fantastic torque and power also..

 

What about those of us that buy into the hype and seem to always have spare parts lying around?

I have a BR-20G-9 going on my car this week. Now if I could only find a use for this TME-based WR, I'd be all set.

 

Shiv I don't know why you can say that the 20G-IX is in a lesser league than the TME.

The 20G-IX from turbochargers.com has a version with the titanium aluminide turbine.. which is really all that the TME has to offer.

Couple that with a bigger compressor wheel AND cover... wouldn't this result in big power gains along with quicker spool-up?

BTW there are two versions of the 20G IX.. one with the regular inconel turbine and one with the titanium turbine with costs of $975 and $1350 respectively.

The 5 blade or 6 blade design? TME based or USDM IX based? If its the 5 blade im pretty sure its just a WR compressor wheel in a IX turbo with a new (more marketable) name behind it.

Also, input from anyone here on the questions I posted in this thread would be appreciated.

So if you have an Evo IX, what would be the best bolt on turbo upgrade? The TT 20g?

 

If I had the time, I'd put this to music, you know, "The Ballad of the 9 20G"

Everything's there: The characters, the melodrama, the bittersweet ending, may be put it to the tune of the Beatles "Rocky Racoon" or something.

(BTW I'm NOT knocking anybody involved, espeically DB)

 

Both were designed to approach the same end. Maximize what little efficiency envelope remained on the exhaust side of the turbo by going to a better wheel design. FP's WR while not as widely accomplished power wise has shown itself to be reliable in the least. Now that the Buschur name is behind the same developments its possiblities have become relevant news again.

If I had an EVO 9 id simply do a TBE/Tune and take solice in the fact that the 03-05 guys have to tear into every part of their warranty to make comparable power on straight pump.

 

And I am one who happens to have the Buschur EVO-9 20G with TiAl wheel. My unit has the 5-bladed compressor, which was installed after the fact by F.P.

My previous turbo was a TME. I installed and dyno tuned the 20G-9-T less than two weeks ago. The only other mod made at this time was an upgrade from a JDM-MR BOV to a Forge adjustable unit. Nothing else was changed.

So, what are my comments?

First and foremost, let me preface this by denoting that I am hearing a whistle that I've never heard before. It sounds like it keeps pace with the compressor, and actually starts while the manifold pressure is still in vacuum, but moving in a positive direction. If this whistle is a leak of some sort, I do not know. If so, that's good news given my results. If not, then I'm not very impressed.

Onto the nitty gritty . . .

- As compared to the TME, the 20G-9-Ti spools some 250-300rpm slower.

- As compared to the TME, the 20G-9-Ti made an additional 10whp or so at the hp peak. . . although we're forcing the 20G-9-Ti to hold an additional 3-4 psi above 5000rpm.

- As compared to the TME, the 20G-9-Ti was down significantly on torque until ~5000rpm. . . but we're forcing the 20G-9-Ti to hold an additional 3-4 psi above 5000rpm.

Now here is what's interesting, around 4000rpm, with the TME and 20G-9-Ti *both* at 25psi, the TME gave some 50ft/lbs greater torque with no significant changes in AFR or timing.

How can this be?

It could be that I have a leak (whistle?), which is causing the 20G-9-Ti to run harder to reach the same boost pressure. We tried raising the boost from 25 to 28 psi, and saw zero increase in torque, which may support that theory.

In summary, the jury is still out, but before I invest more time and money into it, I am actively asking for anyone else with A/B dyno results to come forward as soon as you get them so we can compare.

 

I saw this under hot topics so thought I'd read it. I had no intention of chiming in.

Superhatch,

Not sure who you are, some of your facts are straight, some aren't. That is all I want to clear up.

Turbochargers, long ago, maybe even in 2003, tried to build a turbo that would work for the EVO. The sent it to us. It used a Ford Powerstroke compressor wheel. This was their attempt at making a bolt on turbo for the EVO. It sucked, they came apart, they failed. HORRIBLE attempt at a turbo. Non of this was public, they sent it to us to test for them. I got tired of them failing and finally said to them that we needed to make a TD05H 20G turbo just like the DSM's turbos that we built, sold and had such great success with. I spent thousands of dollars getting a wheel CNC'd, non of them worked out well because of the poor machining that was being done. TC found a shop that actually makes compressor wheels for some large manufacturers. He then sent an actual Mitsubishi 20G compressor wheel there and asked them to make an exact copy of it except reverse rotation. So to say it isn't a 20G, as you did, isn't true. The best desciption of it is a reverse rotation 20G as it is an exact copy. We have ran this compressor wheel with the TD05H turbine wheels in the DSM's for the last 10+ years with huge success. Even John Shepherd swears by the turbo and says to this day it is the best turbo on a street 4G63. My car Talon, after John bought it, was driven to a 10.72 at 131 mph with this turbo. I was only capable of 11.05 at 127 with it. These results are going to be repeated with the reverse rotation turbo, you can bank on that.

I don't know when FP started their WR wheel. We said we were working on one first but that doesn't matter.

Turbochargers has NEVER had ANY EVO9 turbos in their building unless I shipped them there. 1 brand new unit I bought from Mitsubishi before anyone else experimented with one and then 7 more that I bought from FP and had sent to TC to have converted to 20G's.

Then Robert at FP wanted me to try his WR. Which I had only ever seen on 1 car ever, so I never said our wheel outperformed his as I never tested one until about 2 months ago on my own. Anyway he built a special unit for me, different turbine wheel mods and used the EVO9 turbo for the base as I was having good luck with them. When I got the turbo I tested it against the 20G wheel. The results were the same. HP/torque and spool up were basically identical.

To this day TC does not have EVO9 turbos in stock. They ordered 100 units, as that is what I asked them to do. In the meantime I had tested the FP turbo, modified for us, and found the performance and such to be the same so I used them. I told TC that when he got turbos in I would take them from him again. Until then I would use FP for the turbos. TC decided that since I wasn't ordering from them I was done using them. That's BS, I wasn't ordering because he had no product. I think it was his way out of our deal of me exclusive on them. I did all the work on the turbos etc.

That's the majority of the story in what actually happened.

Thanks for your time. Shiv, hope you don't mind me posting this here.

50ft/lbs less? Let's hope that's a boost leak.

 

5 Blade
TME based

It's an original WR, made from a Ti VI TME turbo.
