New APEX AX5782 single turbo
Anybody know anything about this ?
My buddy just told me they have the kit about to be released in Japan. It's about the size of T-78/T04R w/ ball bearing.

That's an interesting and helpful statement.
Seriously, You're in Japan, do you have any info on the AX5782?

I have to say I agree with your statement.
I like lots of the Apex'i ****, and have wanted RX6 Turbo kit for my FD for sometime. Now that the GT3540 kits are out, I have been rethinking my choice. If the New Apex kit offers everything the new GT3540 kits offer power and spool wise. I would like to know more about it.

Thing is, we still can't have their turbos rebuilt here in the states which is why I'd still lean towards the GT series. None the less, I'm with Glassman, I'd still like to find out more information on it. Funny thing, I was looking through some old Japanese RX7 stuff and they've been using the GT series Garrett's over there since the mid to late 90's! WTF? Why has it taken FOUR+ years to discover these things if they're so great?

Here's some translated tidbits about the AX75F82. I believe the AX means abradable seal. This is translated off their Japanese web page using Alta Vista.
"Individual technology of the apex bears the special material where
" ????? " wonderful charging efficiency actualization
In order to pursue further compressor efficiency, with the apex special material " AIRICK of individual development (the ?????)" you adopted for the compressor housing. Because of this by the fact that you bring close to zero not to limit the tip/chip clearance of the impeller, charging efficiency is raised rapidly. In addition, even the occasion where 10001 impellers contacted minimum clearance is maintained by the fact that it can shave the ?????, there is no either worry where the material powder gives adverse effect to the engine.
Is proud of high airflow the new design compressor which
In 1 basis in power of MAX640ps correspondence
At the same time high efficiency in order to acquire high airflow, the compressor housing makes the new design of ????? specification, assures the decrease of inhalation resistance by the fact that entrance diameter is designated as phi 100. In addition, besides the fact that both impeller form is optimized, turbine housing size adopts the A/R25 of single entry type. Installation form of the entrance and the exit gives the compatibility of the other manufacturer, easily replacement is possible. The performance which is superior with 2000 - the 2600cc of the reciprocating E/G corresponds to the output of the 400ps - the 500ps with the 550ps - 640ps rotary E/G."

Notice they mention 640ps for a rotary :-) Here's more...
"The 640PS corresponding NEW turbine " AX75F82 " suction less kit more and more appearance!
At all the Japanese GT championship series where ultra-advanced technology shaves exceeding the AX turbine which is proud of the installing ratio No.1. The AX technology was succeeded, long-awaited kit setting was added to the high power single turbine " AX75F82 " which pursues the new tuning territory. As for kit in T/C itself private SUS manifold, water cooling west gate attachment. In addition the necessary parts which exclude the suction section on the basis of D JETRO conversion are set, installing is made easy. As for the T/C itself the new design compressor housing, in addition to the special material ?????, by the fact that decrease of optimization of impeller form and inhalation resistance is assured, not only sharp standing rising quality, improved even to peak power, and intermediate torque was superior in transient quality, intense acceleration efficiency is actualized. In addition, turbine compressor size loads the A/R25 of the single entry which is superior in matching at the entire area. With the advantage of high airflow, it is possible easily with tuning of cam exchange level to designate high power as the hand. Furthermore, " the suction kit for the AX75F82 " utilization in L JETRO specification. "

I asked about that turbo kit and they said its similar to the T-78. It will be coming over and price is around that of the Greddy T-88 kit. I will get more info soon.

The AX75F82 uses a 64mm compressor wheel with the abradable seal. The kit comes with a turbine housing equal to a 1.00 A/R. The turbine wheel shares the sames measurements as the Garrett P-Trim. It also uses a standard T04 footprint with a divided inlet.
On a ball bearing turbo like the AX53B60, the abradable seal is extremely effective in raising compressor efficiency AND increasing boost response at any turbine speed because there is no shaft play. However, the abradable seal isn't as effective with the standard sleeve type bearings because of shaft play.
We haven't tried this turbo on a Rotary yet, but we've tried it on a drag Honda engine and it made 624hp @ 1.7kg/cm^2. It's a very nice turbo, excluding the price, but it didn't make as much power as one of our T04X^2 with a 66mm compressor wheel. Of course that should be the case with the bigger compressor wheel, but the T04X^2 outresponded the AX75F82 by 150rpm while making 652hp@1.7kg/cm^2 on the same engine. It also costs about $800 less at retail. Results may be different on a Rotary, but we don't think anybody will want to drop their chips on a turbo kit that's probably going to retail around $6k so we haven't bothered testing it.
Just thought I'd let you guys know a little bit about the turbo. For all you that want to flame me out there because obviously this was a test conducted in-house, believe the results if you'd like. Don't believe them if you don't want to. Just don't waste your time attempting to flame me because I'm simply going to ignore it anyway. You guys were asking about the turbo so I thought I'd fill you guys in on the turbo and our results in testing. Hope this helps.

I know there's people that appreciate the info so that's why I post it. On the flip side, there's people that will attack me for just about anything I post, which is why I rarely post. Since I come from a shop, I'm bound to get flamed because my posts are always critically analyzed. Sorry for being so defensive, but I have to be.
We are A'PEXi's number one customer in America. In fact, we account for over 40% of their annual sales. That's probably why we got a couple of sample turbos when we requested them. We haven't tried to order any for sales, but I'm sure it would be on back order if they are on backorder in Japan.
