I am not sure which one to go with. Can someone please tell me what are the positives and negatives to this choice please.

 

The TME turbo comes w/ a 10.5cm2 housing, but the shaft and turbine wheel are made out of titanium.

Going from a 9.8 to 10.5 cm, you'll be sacrificing a little spoolup for better top end. With the lighter titanium parts, you should gain back your lost spoolup.

 

Thank you! As a followup question, does the 03-04 Evo 8 turbo have the Ti internals?

 

well, I have a friend who just installed the TME turbo and he spooled 400-600rpm sooner than the stocker. I recently installed the 10.5 hotside and I spool around 200rpm slower than the stock turbo. Either way, both the TME turbo and the 10.5 hotside are better flowing and can produce very good numbers.

 

Now I'm curious about how a TME turbo would perform if you slapped a 9.8cm2 exhaust housing on it. Maybe you'll get 800rpm sooner spool!

 

Anyone know where to get the 6.5 RS TME turbo besides FP?

 

Although this has been posted before.. the 6.5 TME turbo is different than the FP hybrid turbo.. the 6.5TME has a slightly different compressor wheel..

the TD05HRA-16G6-10.5t is basically what your getting from FP.. and its an amazing turbo for the money.

You can get the TME turbo if you look around for it.. However its very very expensive. the Hybrid is a great compromise, and runs really well.. Everyone who's bolted one up (or even just the 10.5 housing on a stock Evo8 turbo has had encouraging results with it. But the key is to optimize what you have if you want to use a turbo like this.

 

Can you please elaborate on optimizing what I have if I want to use a turbo like this.

Thanks a million!

 

Search for a few threads about the titanium turbo.. I've posted quite a bit about it on several forums..

 

Yeah, my buddy and I (he's the evo owner) have been reading your threads and he is going to have all supporting mods (TBE, Intake, Exedy Twin, Cams, Gears, XEDE, BOV, EBC, Fuel Pump, and Custom Tuning). From what I am reading many people with this turbo are going with aftermarket ex manifold and/or injectors. Does his setup seem like enough or does he need other mods?

thanks, I really appericiate the help!!!!!

 

I have a JDM 03 Evo 8 equipped with a titanium turbo TD-05HRA- 16G-9.8T. With an upgraded Tomei ECU, HKS 272 in/ex, 3inch exhaust, ex manifold, downpipe, I made peak power very early in the powerband. ( 370 whp at 22 psi) To early in fact for my liking, power comes in hard at 3000 rpm at an instant and seems to peak at 5500 rpm and tapers off quickly after that. Made a switch to a 10.5T hotside, spool up is significantly slower, power comes in less harder at a later rpm ( 3500 to be exact) but peak is extended another 500 rpm at 6000rpm and tapers off only gradually towards 7000 rpm. Feels like driving a slightly bigger motor due to slight slugishness of the response now. Will need to retune the AFC to slightly fine tune the mixture. Running richer judging from lower EGT readings..

 

I really appreciate it too, since I am the evo owner blingkus kahn is talking about. Let me know if there are any important mods that need to be done that I am not doing. I will be setup with all the stuff blingkus mentioned, plus obviously I will be getting the 6.5 TME turbo as well. Thanks guys, you help is always appreciated.

 

The jury is still out on the exhaust manifold.. I have a stainless manifold and O2 housing however.. I think you can improve the low-end torque a little with that manifold and improve spool a little, but there's currently not enough data on it yet.

 

I have gone through the entire induction and exhaust system and addressed each component.. I've also got some cheater mods that I don't really want to talk about until I've tested them.

 

I wonder how durable the titanium turbos are compared to the steel units? Didn't Mitsu only use the titanium turbos in the RS and RS2 models of the EVO6 and the steel units in the GSR? Those cars did have anti-lag on them though. So in our case, we shouldn't have to worry about durability since we don't have anti-lag.
