I have been hearing about the IX turbo, and it sounds like a wicked turbo. I went from the stocker, to the TME which is awesome to say the least. If I were to consider the Evo IX Turbo, as a replacement for my TME, would there be enough gains (horsepower and spool )in doing this to justify the purchace? Is there any comparative dyno graphs with close to my mods? Or is it still too early to tell. Thanks again in advance, for listening to my idle ramblings.

 

I cannot speak for the Evo9 20G, but I know of someone who had a TME and went to the 20G and could not make more power. He sold the 20G and went back to the TME. The Evo9 based 20G may be a different story.

 

Thanks for that EvoTech! I will scratch the 20G off my list. (that one really wasn't on my list anyway) Someone knows the definitive answer on this. We'll just wait and see who coughs it up!

 

The EVO9 has the larger housing.. It would definately be a step up.. but i'm not sure if the cost would justify the gains. I would say you will definately pick up some TQ but up top HP wise I'm not really sure.

Bump for a good thread

 

Thanks justchil, hopefully this will help someone "on the fence" as to what turbo to get. Of course it will help me also. Thanks again.

 

I personally could not justify spening 1500 on a new turbo for a theoretical 20-30 hp. I would and am considering Buschurs 35r..

 

I see what you are saying, but some think the HP, and the cash is worth it, to get to those horsepower quicker, with more of a crisp response. I guess it depends on what you want to use it for. Drag racing, GT35R is great. for road racing, auto-Xing, I dont think you want the lag! I am also looking at the GT35R's, but I think my issue is deciding what I want to do in terms of racing.
I might get complete underside upgrades, ie "A" arms, control arms, etc... and work on sticking the car to the track, and deal with the HP.

 

I have the 6.5 TME also, and based on the dyno charts I've seen posted here of the new IX with turboback exhaust (which should help spool), I don't think the new IX turbo can outspool the 6.5 TME. All the IX's seem to start to peak torque wise around 4000 rpm. My TME is well before then, but you can look at your own dyno chart to see how yours compares to the IX's posted here. Vishnu has a couple posted, and there are others.

The IX turbo looks to outflow the TME on the top end, but I don't think you'll gain anything on spool.

How about rebuilding your 6.5 TME with a 20G compressor wheel? It would be cheaper than buying a new one, and you'd be getting the best of both worlds.

This setup is prone to compressor surge though.

 

I think the 35R would be awesome if you can afford to upgrade drivetrain and build a stroker

I will have my E9 20G on within 4-5 weeks but I'm coming from the stock turbo. I should have a better idea then.. although I'm coming from the stock turbo not the TME (which I almost bought)

 

That's a good idea! You could get the ti/al wheel the BR has for it.

It would be kind of expensive but here are some rough estimates

200 for the ti/al wheel
800 for the turbo upgrade
100 something for the install kit for evo8
175 upgraded actuator?
??? Lower I/C pipe solution?

 

I think the compressor surge was the worst on TME upgraded 20g.

 

Good info again, I guess I have to look, or better yet, due to my computer ineptness, could someone post the graphs here? I am trying to see the "bell" curves, and if there is any difference in overall HP. if there is, how much? Also what is the seat of the pants comparison of the TME, and the TME with the 20G compressor wheel. noticable? or negligble. Again this may be too early to tell, but I would like to see the raw numbers, with the combinations abovewith equal or close to equal mods.)

1. TME
2. TME with 20G compressor wheel
3. Evo IX turbo

Is there a gain to have some of the fins "clipped"? on the TME.

 

why don't you consider the 9-20g. It maybe more expensive, but it looks like it is going to be a sick upgrade for the evo 8.

 

Who has it, or is getting it, and is it a complete replacement for my TME, or parts I add to my TME? how much is it, and is there enough gains to justify the cost (In your opinion)

 

Buschur.

There are about 3 good threads about it floating around, here is one of them https://www.evolutionm.net/forums/sh...d.php?t=172380

Their 20G-8 had compressor surge problems, all fixed in the 20G-9. There are also threads david made about roll-on power, proving that the 20G-9 will spank a GT35R in a 3rd gear roll on.
