Sounds good to me.. Similar to what I am doing.. Though I purchased the ti Turbo (TD05HRA-16G6-9.8t) and am adding a ceramic coated 10.5t housing to it... There's not alot of material to port on the turbos, however a little blending and port matching of the inlet/outlet will do wonders.

 

so would i have to get an ems unit after installing a 10.5t or would the stock ecu be able to adjust itself?

 

Stock ECU should be fine, it's just that you'll see more improvements through a reflash, XEDE, UTEC, or AEM.

 

I also think there is some mis-understanding going on of the Evo 6 turbos (and please correct me if I'm wrong). What forced perfromance is selling is really the Evo 6 version...a 16G ti wheel with a 10.5 hotside. The TME is a 15GK2, with a 65mm compressor wheel versus a 68mm compressor wheel on the 16G. I think I have this right. People have just generically been refering to the 16G ti w/ 10.5 hotside as a TME (when it's not). And again, someone correct me if I'm wrong.

 

Hey, I know FP is pretty deceptive-they sell remanufactured turbos for 3000gt VR4s and aren't very honest about it. Their 13g turbo isn't a true 13g turbo...

 

The ECU won't really adjust itself-I have a td05hr 15gk2 9.8t, and my car runs so LEAN until about 3500 RPMs beacause it spools up too quick-I have dyno sheets....

 

TME breakdown
td05h=turbine wheel size
r=reverse rotation
a=titanium turbine wheel
15gk2=compressor wheel size
10.5t=scroll(nozzle) size
TME 6.5t turbo=td0h5ra 15gk2 10.5t

the TME 6.5 turbo is a compromise-I have a steel 15gk2 9.8t turbo on my EVO, and it spins up fast, but loses breath at redline-I think the solution is the 10.5t sized turbine housing. It doesn't make any more power than the regular 16g6 wheeled turbos, in fact it makes a little less, as the 15gk2 wheel is smaller. A TME 6.5 turbo probably makes equal power to a 9.8t steel 16g6 wheel sized turbo, that's found on the US EVOVIII, but simply spools up faster. How do I know? I have dyno charts.

 

Oh yeah, and the 15gk2 wheel isn't really sized that differently-the inducer has a different cut/shape and is smaller than the 166

 

I figure if you remove your turbo, a 50 Trim with a BB center should go on, but thats just me. The TME turbo allows the extra flow of a larger exhaust housing, and uses a lighter center wheel to give the same spoolup as there is a now a LARGER exhaust area which means less Exhaust Gas Velocity to spool the turbo which means lag. WHat can you do to compenstae for this?


1. Lighter componetents, such as a Titanium wheel
2. Pullys, crank pullys, added SO much spool to my turbo it was stupid, full boost dropped from 3500 to almost 3000 even, sick.


Its a great upgrade, but unless you get the turbo WAY cheap and can do the work yourself, Ii see the Money spent not worth it.

 

I was not trying to "call them out". Simply, they may want to change their add as it is incorrect, and people could be mislead. I'm not apposed to doing business with them at this point. As a matter of fact, In my OPINION, they have the hottest setup for everyone less the drag racers... until others start marketing the same set up.

 

Let me get this straight. You replaced a crank pulley and the other pulleys and youre spoolup dropped by 500RPM's. Highly unlikely. DO you have Dynographs to prove this?

 

I am sure that the reflash added to this. But I added a Pully and a flash to tune it properly. The bottom end before with my 272's was kinda shaky, boost would hit at 3000 but not hit 21PSI til about 3500. I added a reflash with the pully, it woke teh car up, boost hit a lot harder and sooner. Pullys really do great things for your car IF IT IS TUNED properly, mine was leaned out to properly take advantage, but from a 1000 rpm roll if I nail it, lag , lag , lag, hmmmm, THWACK at 3000RPM's with my 21PSI spike, it builds slowl at 2500 then just increases exponentially. Also smoothed out my top end nicely, I suggest getting one.

 

Guys, the GSR version of the Tommi Makinnen has a 15GK2 compressor wheel but the RA version ( rally spec) version of the Tommi Makinnen has the 16G compressor wheel ( HRA titanium of course). In fact Evo 5,6, 6.5 in the RA version shares the same titanium turbo series and by far the biggest of them all utilizing the 16G compressor wheel. Starting from the Evo 7 the 9.8T housing was introduced for quicker spool up but titanium was offered once again only in the RA series. IN the Evo 8 JDM only, the titanium HRA series was offered both in the GSR and RA series, only drawback once again is that the 9.8T housing is retained. I recently made a swap to a 10.5T housing on my titanium turbo (JDM evo 8) and the difference is 1) slight later spoolup maybe around 300 rpm later 2) doens't hit as hard on full boost 3) top end pull is significantly better up to 7000 rpm , used to die off pretty quickly at 6500 4) the EGT has gone slightly lower , suspect slightly richer mixtures
Going for another dyno session to fine tune the mixture on my AFC to see if any more power is made, previously made 360 whp at 22psi...

 

Not bad... impressive .

 

Yes, to quote myself...
