Apexi AX7582 Turbo Kit.
Ok ppl. After a lot of search i was impressed that i didn't find anybody using this state of the art turbo. Although many ppl are using the RX6 which actually is only $400 if i am not mistaken cheaper than the AX7582. Does any one got a review or is using this turbo?
Last week we spoke with Apexi and they told us that their drift car driven by Youichi Imamura has the kit AX7582 with their P25 hot side and they make 500rwhp on the 99spec stock engine stock ports. I am really impressed and i still don't know why nobody of you is using this turbo. :confused: |
Come on guys, nobody knows anything about this turbo?
|
Never heard of it. The newest magazine out here(Hawaii) had the apex drift car on the cover with a write-up inside. Maybe i'll go by the store and see what the turbo in the car is and any info on it for you. 500RWHP sounds nice!:)
|
Picture of the AZ75F82/92 turbo, I've see it and it's about as big as a T78! It's power capability doesn't warrant the cost IMO.
|
Doesn't Apexi use Hitachi turbos? I've always wanted to know.
I talked with the driver of that drift car about what turbo he had and he had no idea what it was. He said that he just drove what they gave him. I was very unimpressed with his knowledge. He was just eating up the spotlight by signing autographs at Nopi. Garrett |
never heard of that one ...hhmm ....garrett i belive is right i they do use hitachi turbos ,...right???
|
they use IHI turbos, thats a hybrid of two other models, if i not mistaken, twin BB though.
|
They use IHI turbos as far as i know.
Garrett if you are talking about Youichi Imamura who drives the white FD, maybe he just didn't want to tell you what was under the hood man, because as far as i know he is a head engineer if i am not mistaken in Apexi Engineering and for sure he knows his car;) |
how much does that turbo go for?
|
The AX75 kit for 93+FD goes for about $4500.
|
He really seemed to not know. He was a good guy, just didn't know what kind of turbo they were using. I talked to him for quite a bit about racing away from the crowd. He didn't come accross like a head engineer. Looks are very decieving with that guy.
Garrett |
Are you sure he was Youichi?:)
Anyway lets stick to the subject....Anybody knows or is using this turbo?? |
I heard the owner of HYPERSPORTS (Travis) is using it on his white FD, can anyone confrim this...RETED? :D
|
88fc3sw/HX83 does he has a username in here? Anybody can contact him?
|
Ask RETED, because HyperSports is located in Hawaii
|
I'd like to hear more about this as the info becomes available. I think I'll stick with my plans for the GT40R, but information is power and one can never have enough of either!!

Ax75f82
the Ax75f82 is impressive but still not the top of the line (Ax75f92).
Claims that it can go up to 630hp. The A/R is 25 mm. the exhaust manifold data is SUS304 ö60 t=3 i dont know what it means but i think it uses a t3 flange?????? im not sure...(1 big sqare hole and 4 very little ones on the side) it came up on a discussion one day with my friends. He actually saw an rx-7 done by garage prestage in japan. Their fd was running on 850cc injectors and set on 1.3 running at 430 hp. I never heard of anyone using ax75f82 running above 500 hp. All fds that i researched using this turbo is running 1.2 or 1.3 at 430-450 hp with 850cc injectors. maybe u can squeze more but if you insist on AX75f82 then just stay at that level for now on. If i have the money? buy this turbo kit. IHI is famous for making reliable turbochargers. Anything that is inside ferrari f40s and nissan r390s will have my vote. As for youichi imamura, he is a funny guy. If u see his antics in option videos then u know he is not to be taken seriously. He used to drift in a beat up charcoal black ae86 and was driving for the bride sponsored civic in super taikyu. Then when apexi came, then he started using turbo cars such as altezza(with apexi turbo in it) and rx-7. Maybe he just did not want to get into the specifics, he dont have to know anyway. he has a team dedicated to him so he just let his team know how he wants the setup to be. |
If this turbo is bigger than the RX6 then raising the boost above 1.2 or 1.3 bar would be no problem at all. I know for a fact that IHI turbos are reliable. They make some of the best "drop in" turbos for the WRX community. I have seen unreal dyno numbers from guys using the IHI turbos. One of them is my very good friend running the IHI VF34BB. He put down 419awhp @ 21psi with stock internals with his '02 WRX. I know that the WRX is a totally different car than our 7's, but I was talking about the IHI turbo more than the car. Ok, I'm done rambling now.

Here is a translated link for all the specs on all the apex turbos. the ax series uses a t4 flange and the 25 is a code for the a/r which has a mm designation but not sure how it compares to a/r. I am not sure what the code break down is but I bet it is a .96 because I have heard that the P27 is a 1.06. The p27 is the largest they make but remember that this is relative to the frame you are using. A t25 with a 1.06 is different than a t4 with a 1.06.
btw: after pulling my apex rx6b, I measured the exhaust flange and it is about the size of a t25 but the wheel is a lot bigger. I wonder why they use such a small flange? mike http://babelfish.altavista.com/babel...01_turbine.htm |
mmmmmmmmm
dang it, i thought .9 a/r is big enough already
is your exhaust flange divided into 2 square holes or just one? |
just one.
I noticed the link did not work. Just go to altavista.com. Click on transrate and then pick japenese to engrish. type in www.apexi.com and go to the japenese site. When ther go to the turbo section and click on thr link for the rx7. there will be two squares at the bottom left that say data. the one on the right has all the specs.. mike |
Ok ppl some more info.
I just ordered yesterday a kit for FD3S (after we got an answer from Apexi) with the AX75F92 with P27 hot side. This turbo has inducer 92mm (T51R-KAI has 94mm) so they are almost the same size, P27 hot side has A/R 1.06 and Apexi claims that the technology used on their bearings Dual Ceramic BB makes their turbos the fastest/smoothest spooling turbos in the market. More details when i get the kit on my car. I will post some numbers and dyno sheets as well. The whole setup will be. My 99 spec motor stock ports for now, Apexi GT spec FMIC, PFC wih commander, 1600secondaries, Apexi internal fuel pump, Apexi FPR, Cusco twin plate clutch with flywheel kit, koyo radiator,and all the stuff needed for a single turbo FD. I'll let you know about the proggress. |
Racer1, are you sure this turbo is BB. The spec sheet on the japan website says it is "floating metal" not Ball Bearing as listed for the rx6 and smaller ax series. You are correct about the inducer being 92mm but they show the exhaust as p25 which is .98 a/r. I figured out how that works, just divide the mm designation by 25.4. Ie: a p27 is 27/25.4=1.06.
It is definately a t4 flange. This turbo should moves some serious air. The major on the exhaust side is 74.1mm with an exit of 70mm. The compressor housing is 17.8mm or .70a/r hope this helps others. |
Michael Filippello yes i am 100% sure that it's dual ceramic BB. As for the exhaust this turbo comes with P25 but it's optional to put P27 so i've ordered a P27 with A/R 1.06
|
sounds good, just wanted to make sure everyone gave you the correct info. On a t4 footprint you would be ok with either a/r. .96 would spool a little sooner.
I wonder why the japaneese website got that very important detail screwed up regarding the BB issue. That is the problem with websites sometimes. You find conflicting data on the same webpage. let us know how the turbo works out. I bet the down pipe is bigger than my rx6:) mike |
oh and btw, you know that the trick thing about the AX series is that they are abraided turbos. This means that the compressor housing is made with a material that is worn away to a perfect fit when the compressor is first spun up. They can make the tolerances much closer, 0 actually and let the wheel polish itself in for the least needed clearance. This means no blow by and if the compressor ever wobbles or gets a little play, it just machines itself a new path maintaining the closest possible fit throughout the life of the turbo.
|
Well thats something i didn't know. Thanx:)
|
That sounds nice, I wonder why more companies don't use the abraided technology. That sounds like it would be the ticket. That also might explain why the Apex'i turbos are more expensive. But hey, gotta pay to play right. Racer1, I'm very excited to hear about this turbo once you get it up and running. Please keep us all tuned.
Zach |
Anyone know the cheepest place to order one?
|
according to apexi it isnt released yet, i spent a good 20 minutes on the phone with them earlier today
|
It's not available to the "public", but if you're a dealer, you can get it...what a bunch of crap!
|
I know an Apex'i dealer if anyone wants one that bad. Just PM me and I'll set you up with him. He's a really good guy and runs a FIRST RATE business.
Zach |
well Im a dealer as well, and I was told I can pre order it, but itsnt ready to be shipped yet
|
Apexi needs about 1-2 months to deliver it. And they told us once it is ordered from IHI the order cannot be canceled.
|
About how much is the kit retailing for if you are a dealer? ( I know a dealer or three)
|
Abraidable compressor housings are the shiznit! But, unlike what was said earlier, as the turbo wears out and wobbles the tolerances get WORSE, not maintained. Chances are the looser tolerances still will be tighter then a standard non abraidable turbo, and a plus would be if it ever got really bad, your compressor wheel wont grind itself to death, but who runs a turbo to that point anyway? I'm pretty sure that the 96-99 FD3s had abraidable twins. Seen it in a MAZDA rotary history book when my buddy was buying a Rx8 at the dealer.

Links to back up 3rd gen having this abradable featurhttp://www.ttrex.com/RX7History.html and

Mike, thanks for the info. That would explain the huge price difference between the '93-'98 turbos and the '99-'02 twins. Now I just have to wait and see how the person that ordered the Apex'i unit likes it once it arrives. Everybody keep your fingers crossed. This might be a killer find!!
Zach |
If anyone wants one of these kits let me know.
I can special order it. Jason |
Jason, I email you concerning the fact that I cant access me pms, please respond if u get the chance
|
Jason, do you have a price for the kits?
Jim |
Apexi answered today that the turbo will be ready for shipment in 2 weeks. I'll keep you updated. :)
|
I will have a price on Monday.
Jason |
I can't wait to see the price. But at the same time, I don't think that I want to see the price. I have a bad feeling that it's going to be ungodly high. Gotta pay to play though!
Zach |
The price i got from my friend(dealer) is $8000 for the turbo kit + GT spec IC kit + suction kit + PFC with commander.
|
Suction kit? I'm not familiar with what that is. Could you explain it to me please? Thanks in advance.
Zach |

What makes them so impossible to service? Just unavailability of parts?
|
Im sure any IHI turbo repair shop can do the job, IMO.
|
Its the availability of parts for the turbo.
