lol.. funny

I hate to break it to ya, but all sources (even from Apexi themselves, as I had posted in links one page back) say that the turbo is NOT ball-bearing. The only turbo's Apexi has suitable for 13B's that are ball-bearing are the Rx6 series.

This is not exactly correct. The smaller ax series are also ball bearing, just not the 82/92. I still doubt if this info is 100% correct however. If he has the turbo, could it be that it is indeed ball bearing. I know reted stated in the other thread that he had messed around with one personally and that it was not ball bearing. I guess Jason needs to shed some light as he has it and knows what to look for.

Here is where I got my info

^^ Thanks for the correction!

Oh yeah?
I think you were taking crack at the time.
I got to mess with the first one brought into the U.S., and it definitely wasn't ball-bearing.
I've also messed with a Turbonetics 60-1 BB and a Garrett GT3540 and GT2530's, so I know what a ball-bearing center is supposed to be like - do you?

We are talking about an AX7x turbo right and not the smaller AX5x models?


-Ted

Anybody care to take a guess at spool times for the AX7x series turbos? I know its a stab in the dark, but would be comparable to what type of turbos?
Or better yet a dyno sheet of the 500+ Japanese Apexi Drift car :eek:

Ill let you know in about a week, the engine is just being broken in right now then its getting tunned and ill post the results

Main distributer for Apexi in Australia (Access) said that they were indeed ball bearing.
When I explained that on the Japanese site it stated "floating metal" He replied "Mate, they are ball bearing"
BTW not saying they are or arn't, just very disapointing if the main distributers dont know what they are talking about.

i've been keeping an eye on this thread to see what turns up. There seems to be conflicting information. who knows how old those spec sheets are? Maybe they used to be bushing and now are BB and everyone is correct. I thought Jason received one. He should be able to say for sure what he received.

Whats the scoop, Jason?

You can read it yourself...

This is the current info posted on the A'PEXi Japan website.


-Ted

I have linked the same info. Since I have personally never put my hands on one, I am not saying it's one way or the other. Would be nice if someone else who has a new one arriving could reaffirm once and for all.

Mike

The 13B rotary engine that powers the A’PEX USA FD drifter was originally found in a JDM 1997 Mazda RX-7. Although the internals of the 1.3L remain relatively untouched, power output was greatly increased thanks to the full assortment of A’PEX products, including an A’PEX AX7582 turbo kit. At the heart of the kit is the AX75F82 ball-bearing turbo with ‘Airick,’ a patented design by A’PEX that ensures maximum turbo efficiency and output thanks to the special material embedded in the internal compressor housing.

^^^^^^ couldn't have said it better myself..then again kind of sounds like you copy and pasted that out of SCC magazine from a couple months back...either way its a sick turbo

Throw the dyno sheet up. :bigthumb:

FWIW, on the US Spec Apex'i drift car, they have recently dumped the AX7592 and switched to the RX6 for drifting. My friend calvin now has the AX7592 that was on that very car

is it the same calvin that was at d1.. calsonic i think was his name. i am using the rx6 now and was wondering if i could buy just the ax7582 and keep my manifold.

You cant use the RX6 on the AX manifold since it uses a T4 flange and the RX6 is a T3.

I had posted a dyno graph of that turbo a few weeks ago. Its probably on the 2nd or 3rd page.

Jason

ahhh thanks for the info jason.

And where was this taken from?


-Ted

I believe Airick is just Apexi's name for an abraidable compressor housing. Basically the first few turns of the comp wheel will shave that material off of the housing, giving the turbo a zero clearance tolerancy, and better efficiency. However, the downside is its expensive, and if the turbo were to go out of balance or get some foreign material in it, that abraidable housing will wear down further, totally ruining the whole concept behind it.

I saw that dybo run, thanks. But there are suposedly 3 others running this turbo and would like to compare notes. Especially sombody running the AX82 not 92.
So post them up yall.

Yes, it's the D1 calvin. He is sponsored by apex'i so he got the turbo off the US Spec D1 drift car.

Any updates from anyone?

my friend just made 387rwhp @ 1 kg with this turbo kit at xs engineering two weeks ago

would love to see a dyno sheet on this overpriced turbo kit....sounds yummy

waaaaaaaaaaaaaaaay overpriced haha

Hey artguy, are you in SF now???
