That looks like an English translation of the T04Z HKS release brochure.
What's interesting is the AX75 graphs.
The AX75 is the big A'PEXi turbo for the FD3S.
The AX75 is NOT an ball-bearing center.
I dunno how A'PEXi managed to get this non-BB turbo to respond so well.
The AX75 uses a Garrett T04 turbine footprint, so it fits a lot of the T04 turbo exhaust manifolds available.

AX75F82 is a bit smaller than both the T04Z and T78 though.
If we go by inducer size, it is 64 mm vs 67 mm for T04Z and T78, hence less potential although I'm not so sure how the turbine section of AX compare to the other two.
What's really interesting is the fact that the T04Z outspooled the T04R by 1.8 second in 3-4 gearchange. But when I looked closer, they compared the 0.81 A/R T04R to the 0.61 A/R T04Z. Bastards.... of course the T04Z spools quicker. Nice marketing there HKS.

so would the . 81 a/r divided be too small for a rotary? i know some ppl use the .81 q trim on a t66. or would a rx7 be better off with the 1.00 a/r divided? mainly for street driving.
Thanks
Thanks

The AX75 maxes out at around 500hp at the wheels.
The T78 should do better.

There are two kinds of AX75. The big one the AX75F92 is bigger than the T78 almost the size of the T51R-KAI and the amazing on this turbo is that it's using a new technology called Floating metal instead of ball bearing and believe me it's MUCH faster spooling than the dual ball bearing. Also it is using the abraided technology so it has the best clearance between the fan and the housing which makes ii one of the most efficient turbo ever been made.

If so then all the race teams in the world would discard ball bearing turbos for these new wonderful floating metal bullshit right ?
Please back up your claims with some accurate data...

As i said it's a new technology, expensive turbo, and you won't find it in many cars. Actually the only car i've seen it, is the Apexi Drift Car and it's not the AX75F92 it's the smaller one.
I'll be able to back it up and post some dyno graphs as soon as i get it installed on my car

"Floating metal" eh? To me that name suggests a plain bearing (i.e., the metal floats on a layer of oil), unless they've come up with a way to run a magnetic bearing in a turbo
Do you have any links to a description of the this new bearing technology? I ran Apexi's website through babblefish and the translation only seems to suggest closer impeller tolerances, perhaps via an abradable seal.

I agree with artowar, I think floating metal is just plain bearing technology.
racer1, please do that. Also, where do you get the kit from ? Direct from Japan ? How much is it ? Please post pics before and after.

Actually i am buying the kit direct from Apexi Japan and what i've posted is what they've told me on our phone conversation before placing the order. It will cost around $5000.

Interesting marketing by APEXI. They sold you on standard journal bearings by calliing them "floating metal" technology. Unless you can back up your claim with an article or something we would have to presume your car is also powered by unabotanium alternative fuel. Which I heard is the heat on Cyprus.

Apexi seems to like to develop their own products, so perhaps they've actually come up with something new that does work better than ball bearings. That would be good news.

back to the t04z. would you guys think the t04z .81 a/r divided exhaust housing would be good on a stock/mild streetport? or it would be too small?
thank you
thank you
