Apparently there was a flier handed out at SEMA 2012 giving us a heads-up about a new turbo being made by Mitsubishi Heavy Industries (they are the ones that make the turbos) for the EvoX. I did a little research on this unit specifically and it looks like it flows a "hair" faster than a BB FP Green. Yet, the MHI turbo is still a Journal Bearing. Numerous vendors claim to have this item in stock and it is selling for $1599. I am still waiting for an official review with full bolt-ons as I am particularly interested in something less powerful than a red, but yet a cheaper solution than a green that still almost guarantees me to break 425whp without the necessity for aftermarket manifolds (mapef2). In other news, I also learned that MAP is also creating an EF2.5 which I have no real information on. It was recommended by an employee there to run cams, but who really knows how the MHI vs EF2.5 will stack up against each other on the dyno. I eagerly await results!

Nice! cant wait to see the pwer it puts out with bolts on compare to fp green

 

I'll have EF2.5 results next weekend.

It's "recommended" to run aftermarket cams with any upgraded turbocharger. Why? Because you'll make more power. I personally refuse to give up my perfect drivability so I chose to stick with the stock cams on my EF2, and have chosen to do so with the EF2.5 too.

 

^ r u running the manifolds

 

-Mil.Spec ported intake manifold
-Mil.Spec 64mm ported throttle body
-MAP ported/coated exhaust manifold

 

^ hellova extra stuff. wanna see graphs without those mods

 

To give you an idea of what they're worth, here's what those mods did on my stock turbo car:



The gap will be larger the larger in size turbocharger you go.

 

I also see you are running 27psi. Was the pricetag of 1.5k + adding another 2psi you spent worth about 10whp/15trq and the opportunity to break 400 on an EF2? Did you ever think to yourself "why didn't I get a green and be done with?"

 

$1500? 2psi? Honestly, what are you talking about?

I'm running the exact same peak boost with the EF2 as I did the stock turbo (before and after the manifolds). I can also ensure you that I did not spend $1500 on the manifolds and throttle body; even full retail price wouldn't land you anywhere near $1500. Even if I had, the gains are solid and proven. It costs money to maximize setups, which was my goal before upgrading the turbo.

Regarding your EF2 vs. Green comment, Cobb, who has a lot of experience with FP turbos, estimated my car would land right around 390whp if I were to add a Green (which I had already purchased from them). Instead, I sold the Green, got an EF2, and hit 400 flat. How exactly would a Green benefit that equation or have saved me any time and/or money? I'm not attempting to say the EF2 will make more power than the Green since I have not personally done that test, but it's a very safe bet to say they are very equivalent turbochargers in terms of power output. A good friend of mine down here has a very similar equipped car as mine, only with a Green, and him and I are always right in the same ballpark in terms of power for any given mod level.

 

Such a waste in journal bearing form.

 

I've actually been quite impressed by the EF2.. Prolly more so than the Green. Always great numbers. Plus there are quite a few people that have had oil leaks with the FP turbos.. apparently.

But let's keep this thread on subject! I'm really interested to hear about this new Mitsubishi turbo. Where can we purchase it from?

So, it's basically an OEM quality turbo just with bigger guts? I realize that this is what stock frame turbo's basically are, but the aftermarket parts usually aren't up to OE standards..

 

How's that? Journal bearings have proven themselves to be very reliable over the years in numerous OEM and aftermarket applications. I have 25k miles on my EF2 and my above mentioned friend has about 45k miles on his Green and neither has shown any type of bearing wear issues. Heck, look at how long some DSM turbos, both stock and aftermarket, are lasting. It's not uncommon to see a 20+ year old DSM turbo still alive and kicking; 30+ if you want to count the StarQuests from the 80's.

If you're having journal bearing failures chances are another problem is the cause, not the bearings themselves.

 

Thanks to Kamak Dyrnamics..

 

The compressor cover looks very similar to FP's, which makes sense since Robert flew out there to help them with it. I wonder if they'll be including the cast 3" inlet as well? I'm sure it will be a very capable turbo.

 

The FP turbos were all JB's and there are people with two and three failures from thrust loads. With BB these thrust loads are virtually limitless and hence why they rarely fail.
