Wow with all this said the 6 blade wheel is not a "custom" unit. It is a stock replacement wheel off a truck with a tdo6 on it (cat out of the bag). It is a very common wheel. Now the 5 blade unit made by david is custom and if you wanted it, it can be had in a few months since he only owns it for that much longer (unless he paid for the mold by now then he gets to keep the casting mold all to himself and we will never see one for the srt-4) There is also the white rabbit wheel but they seem to be having issues with it. I didnt read this whole post so if I am double informing you sorry.
yup, like you and i spoke on the phone about...the 20G-6 blade is from turbochargers.com, but is from a non-american truck, with mitsu TD06...
...the 20G-5 blade was designed and built for david buscher through another fellow/company, robert from forced performance...
...so john (hope the surgery recovery is going well)...if you manage to get hold of the 20G-5 comp wheel, then i'd like dibs on one...since i'm being all information trafficing & such ~ LOL
seriously though, i have been doing some other reading on the comparisons, including about the pressure differntial issues of the 20G-6 at higher boost levels (27-28 psi)...and corrisponding increase of IATs...
...if this is the sole issue of the 20G-6 vs. the 20G-5...then perhaps it would be relatively easy to get a casting made of a 20G wheel made, with everything identical, just 5 blades instead of 6??

...do you think is possible?

Yes very possible, just you need the $15k for the enginerring and molding cast, then you have to pony up for a minumum 100 wheels. But since we are taking a current cast then we might be able to get the initial cost down to $8K. I would do it if I had the funds but I can not run out and start competing with David and TCC for the stg 3 and evo 9 stuff just yet. 2 years from now it will be much more different to get somthing like this done but right now I am stuck with my current log of parts and getting the SS turbo off the ground.

yes, for sure...i had/have no idea of the production costs...so even at that,. it's quite an investment
it's to bad dave didnt respond when i asked about the 5 blade use on a S3 cartridge...
...as he did say, he's quite full / busy with just doing Evo stuff!
I dont know if he's doing well though...at $1300 each conversion (includes the seperate turbo shops work and balancing)...
...he is still making likely $400-500 per unit, and likely has done (is doing) about 40-50 untis by now = $16000-25000...then minus $15000 in R&D/casting = only about $1000-10000 difference!
he will do it for you...if you ship him your crap. he will NOT give information or the wheel. makes me curious as to why he is being so secretive. if it was as good as he says it is, more info might be available. belive it or not, evom is harder to get GOOD info from than here

that's right...he was only willing to have the turbo shipped to him, and be it at what ever expense was necessary since it would be a "custom" job...
there certainly hasnt been clear info provided on the board (evom)...and try and just find a good dyno comparison

the white rabbit turbo is, from what i hear, a nice upgrade for the evo. it keeps stock spool and a slight increase in power on pump, but really shines on racegas
its all about the dollar, not the sport. and places like vishnu and AMS who dont make money on it refuse to get involved. too much drama between shiv and david.
my emails with dave were that given his protecting an obviously proprietary product, that there was (could be) an interested market within the SRT4 community, should he choose to take advantage of that...
...with offering of an upgraded S3 TD05 install of his 20G-5 comp wheel
when i tried to get a bead on cost (because i was not about to spend $2000++ and supply a core also) ...i could not get anywhere...basically he was just not interested
a white rabbit is just about the same size as the 20g and its a 5blade. you can get that one from forcedperformance with no issues...other than $350 or so upfront.

...interesting!!
the white rabbit comp wheel is supposedly about an 18G size...I havent seen one, nor know the sizing...
...it'd be interesting to know more on it's spec's & availability! (hint)
If it's *about* an 18G in size then *theoretically* it's supposed to flow just a hair short of a TDO5 20G but was designed to fit into a machined 16G housing. In the DSM world there isn't much value given to the 18G as it's never really been shown to perform better then the Big16G. The big16G costs less & is more readily available so that's also a factor.
Now maybe the white rabbit or what ever it's called is a bit different but I'd be willing to bet that the Evo 8/9 16GC wheel flows just as well at for a fraction of the cost. Although I'd love for someone to prove me wrong.
As far as the 20G wheel goes... I'm wondering if that much extra flow will cause issues with the PCM kicking it out of HOM?

it might...we'll see yet
i have a 16G6 also, so may be able to yet compare...but i am fully expecting there to be a noticable lag over the S3 15GK (or even of a 16G)...with the 20G in place
having said that...like i have said before, if there was a back to back comparison of the S3-15Gk to the same with a 16G6 wheel...i would be surprised to see much, if any performance increase with the 16G over it
where i expect the 20G to work is the upper rpm, and racing gas...
...who knows, i may end up going with the 16G finally, if i find the 20G to much of a lag-munster.
I have a friend that wants to give me his stock 03 evo VIII turbo and I was curious what all I will need to run this turbo. I was told I can upgrade the hot side wheel to a 10.5 and make it even better.
I have a DTEC fuel computer and stage one ECU and stock injectors. My other mods are listed below. Do I need a new exhaust manifold? If so do I need the mitsubishi evo manifold or the mopar stage3??? Any other info would help. Is this a descent upgrade for my car?

Before you start a custom turbo install like this one, you need to do some more reading & reasearch. I'm not trying to be a jerk or anything but this isn't exactly a bolt on affair. If you don't know what parts you'll need then you also probably don't have the skill required to do the install anyways. I'd hate to see you get in over your head & be frustrated because things aren't right.
I'll help point you the right direction. You can use the S3 exhaust manifold but they're very hard to come by & usually not cheap. You can also use a custom manifold that's made to fit the Evo divided exhaust housing. or you can use the Hahn's Racecraft manifold & their turbine housing to bolt up to the Evo turbo. But at that point you might as well just buy the whole Hahn's turbo kit & call it a day.
