I would say a TME that is converted to a DBB FP White. The other option would be an HKS turbo. The faster than stock spool and the potential for 450+whp is a deadly combo.

 

I could agree with you Batty on the new HKS BB turbo. But, the other thing isn't going to happen: A DBB FP White small HTA comp wheel mated to a TiAl TME turbine wheel....ain't gonna happen.

 

I agree it is very UNLIKELY but if you wanted the best repsonding turbo around I am sure you have it done. It wont be cheap but it will be responsive!

 

I agree. But then you might as well throw on that Mag compressor wheel from the British IX RS turbo which self destructs.

 

Thats why I spec'd the FP white. I have heard that compressor wheel spools faster and makes more power than stock and is tough as nails using FP's 2000 series billet AL cpmpressor. I would say that for a lot more money that would be an HKS killer. A BBK lite with TiAL turbine and DBB would be prob just as sick. Just those options would be in the 3K range. 1100 for stock turbo, 1K for the conversion to White or BBK Lite and then another 800 or so the make it DBB. I wonder if FP would make a white using a new TME core for close to the same price? I also wonder if that turbo would be surge happy? There is such a thing as a too fast spooling turbo. Using the 84mm ported shroud would be nice on these fantasy auto-x turbos.

 

The FP white rabbit was a TME with a green compressor wheel. I had one. It spooled like my stock 9.8 turbo but made another 20-30 hp on pump gas over the stock VIII turbo. I agree that the stock TME turbo is definitely not a 100 whp boost.

 

Perhaps you are unwilling to take specific data information from FP, or just don't know. Let me quote directly from the FP description of the T.M.E. turbo, which they sell:

"Our AEM EMS datalogs show a .3 second boost recovery to 25psi during shifts while producing in excess of 370whp through the stock intercooler! So, FP tested the TME turbo, and this data is directly from their testing datalogs...

With any reasonable mods, like an intercooler than is more efficient and has less pressure restriction than the stock one, the TME will put out well in excess of 400 HP, with lightening quick spool. That's 120+ HP over stock configuration.

The OP wasn't looking for the ultimate custom hypothetical combination of parts that might make a better autocross turbo, he was looking for one that is available and works. The TME is a great example of one. The FP GreenHTA would be another, if you wanted more power and were willing to give up a little on the spool end of the equation.

 

I'm not saying it's not fast, but my other cars are all NA...
The Evo is fast once it gets going, but the moment of lag feels pretty slow by contrast. If I ever wore out my stock turbo, I'd want to do something about the lag. It's more bothersome on the street than in autocross, but sometimes it shows up on those turns where they put a zillion cones around the pivot cone, and limit the available turn radius.

I think some of the lag, in street driving, is probably a software issue. I think manufacturers are using these electronic throttles for emission control, and not anything that helps the driving experience. I assume all the aftermarket computers and tunes correct that, but I see I'm not the only person on the forums looking for mechanical solutions to speed up the spool.

 

Yeah, that's what I remember reading on their web site, and I thought it was pretty impressive. They got even faster spool with the 9.8 square cm turbine inlet, but maybe they ran out of those. They don't mention it any more on the web site.

Regardless, Mark Daddio had about 360hp at the wheels the year he ran the TME turbo. I think it sounds like a pretty impressive unit if it fits your car.

 

I'm pretty sure Daddio was tuned on 100 octane, so not that impressive by today's standards. A TME is just a faster spooling stock turbo with better transient response. The faster spool produces more torque down low and therefore a little more HP below 4000 rpm, but most of the powerband is unchanged. There are many TME dynos on EvoM during the 2003-2004 period. Check them out. They were popular back then with Vishnu crowd. TedB ran one as well with meth.

 

The TME turbine is worth about 150 RPM faster spool, from what a local to me noted when he went over to a "TME9" turbo. I contacted FP about building an FP White with TME turbine and they recommended against it as they have seen high failure rates on the TME turbines. They said the shaft separates from the wheel and it is merely a matter of when it will happen and not if it will happen.

As for auto-x on large turbos, you can auto-x just about anything. How competitive you want to be is a different story. I've auto-x'd a 10second honda with a T70 on it. The car actually did pretty well as it was a high compression setup and weighed 2400 pounds so it did as well as the N/A hondas when off boost then did about 100mph on the straights where every other car only got to about 60mph. Of course, it had lousy brakes as it was a drag car so standing on them at 100mph got interesting. The 1000 lb rear springs and 200 lb front springs to help on a drag launch also made the car a hand full. Drop throttle on corner entry then stand on it and you could do a smokey FWD drifing burnout with the tail hung wide.

 

People talk about FP White like it's really responsive, but I don't see one for the Evo X.
Has anyone heard if FP is going to make one?

Or, is there just no demand in the Evo X crowd?

 

I think FP tested the stock X compressor to 47 pound/min, which is the same as the FP White. No reason to replace the stock compressor with it when it offers no higher flow.

 

My answer to this, if you have to ask then you need to run a stock turbo.

The stock turbo can do 400hp/400tq and there are few people that can actually handle that power let alone more and actually be faster with it.

Now if the question is, How big of a turbo can I run and still be competitive autocrossing...that's completely different and from the prospective of not a dedicated autocrosser.

 

Why bring FP into the discussion? That's like bringing your bigger brother along to back you up in a schoolyard scrap.

There is no way that an VIII TME turbo is going to put out 100 horsepower more than a stock 2005 VIII 16G USDM turbo, all else being held equal. No way! I am willing to bet a couple of grand on this. Actually, I'd bet more, except I am currently broke.

Just think about what you are saying, man. Surely you know that you are wrong. Probably you just pushed the zero key one too many times(10 vs. 100). You are arguing strictly for argument's sake, right? It was a typographical error, no?

I am really surprised. You've been on these forums as long as I have and have more Mitsu experience and savvy than I do. That's for sure!
