apexi dont release compressor maps, like hks.

theres probably not a great deal of information as not many people use them. people prefer to use a proven and well used combination, as you can see what results youll get and it takes out the guess work.

the rb25 turbo upgrade thread covers most of the common turbo's so you would be mad to go out on a limb and choose some not tried turbo and be disappointed with the results

[mad082]

or you could do something not tried and end up with good results. just because the majority do something, it doesn't always make it the best.

Just google "apexi AX53B70 turbo" plenty of info out there

from what I understand, better response then a HKS 2535 and more allround power too.

if I had the cash to buy a brand name turbo - my money would be on this turbo

[Munna1]

Sounds good tangles very interested in how they would compare to the GTRS turbo.

cheers

[SimonR32]

from my experiences with owning this turbo, but on a rb20 and research into them on a rb25

they are nearly as responsive as a hks 2530 and around the same power as a gtrs

ultimate low mount for this kind of engine in my opinion

seen one make 238rwkw on 10psi with a nearly perfect torque curve

[GtstCoupe]

that is good power 10psi , yeah i woundlnt mind going something different and it is a more complete kit with all gaskets etc, but the gt-rs may come with then but they may come with them, looking to also find a power figure ,but i s kinda hard to find for the 25det heaps for sr20 etc

[Primordial]

I've got one of these running on my car..

Mine is putting out 225kw at 14psi, but i'm running a very safe tune (rich) and i've got some other issues that need sorting out (need hiflow cat and cams). These turbos have AWESOME response. Everyone that has tuned/driven my car is amazed by how meaty the mid-range is. Power capability of the turbo top out at about 270kw I think. There are a number of guys using the same turbo on SAU actually.

Bunta - has just had one installed - 240kw untuned

Phat6 - http://www.skylinesaustralia.com/forums/in...howtopic=120898 - Just sold his GTS-T with this turbo which pulled 240kw.

This thread has some more info: http://www.skylinesaustralia.com/forums/in...&hl=AX53B70

I'd definitely recommend it!

Dyno Graph:

[paulr33]

its nosing off past 6k

i dont reckon it would go past 250kw

[Primordial]

yeah i've heard that it runs out of huff around the 260 mark, but also heard that some people have managed more. with the way that dynos can be incorrectly calibrated though it'd be easy to overshoot the 260 mark

[GtstCoupe]

tho 260kw + response = goodsetup , it is sounding good ,how did you find installation Primordial ,allgood parts etc

[Primordial]

i bought the car from japan and the turbo came with it, so unfortunately I cant help you there

[GtstCoupe]

ahh yeah i just finished reading you threads ,wasnt bunta running like 20ish psi or something like that to get his figure, might have read wrong

:-)

[Primordial]

Nah Bunta was getting 245kw on 1.1 bar (16psi)...

"Finally got the results back from tuner...245rwkw VERY conservative tune and 1.1bar of boost not sure of the torque figure as I have not actually seen the graph yet, The tuner wants me to run it on this setting for a month or so to make sure everything is coping then he is confident that a bit more boost and a more agressive tune will get another 20rwkw roughly! So there you have it! Somthing to compare too at last!"

[R33_KRAZY]

hey i have this turbo,

but am yet to install.... very interested to see as 2 what people say about it... i decided myself to go out on a limb to see what they are like as there made by apexi i figured they would have to be preety good...

all help apreciated here...

[Tangles]

One of the lads in the sa section suggested that he was pulling 300rwkw with one of these, a whole lot of mods tho (maybe including engine rebuild) I believe.

Fact is, Id love one of these turbos, but I could never afford a new one, and after months of searching for a 2nd hand one I sorta gave up. Im going to use Slides turbo for around 3 to 4 yrs, and then relook for one of these apexi turbos for my awd stagea.

[Munna1]

Anyone know where a new one can be purchased from? and how much they?

What is the turbo based on? ie hks is garret based

cheers

[Primordial]

They're based on IHI turbos (Subaru use IHI for OEM turbos I believe)

[Munna1]

thanks Primordial.

Found this page

http://www.apexera.co.jp/carlife/pro_apexi.../ax53b6070.html (use bablefish to translate www.altavista.com)

I worked out from the pdf that it would cost about $2,588 before delivery.

Anyone who of any other places this turbo can be purchased from?

cheers
