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

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

:)

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

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

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:

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 :)

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

Quote:

Bunta Wrote:

"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!"

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...

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. ;)

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

    • Unfortunately haven’t taken pics yet after it was finished. All the edges are hemmed nicely, just had to cut holes for the gear shifter and seat bolts and seat belt bolts in the rear. The molds seem like they’re done with steam and a layer of glue on the underside to hold a bit of shape but still soft enough that it’s a good fit when it’s all pressed down.
    • When's the rear mounted turbo kit coming? Needs dose and V8 chop idle lol.
    • I was very unimpressed with how the car came up from the A pillar forward, before I hit things (twice). It all has to go. It had to go, but now it has to go... more. So we finally found the very first Shennanigans with the entirely perfectly setup engine that had no problems being pulled apart to improve on 'was perfectly fine'. Cam bearings looked a bit... stock. Which isn't entirely bad given they were stock and this is a ~20 year old engine. So new cam bearings are on the way because it's somewhat difficult to get to this stage to do it later, and it will trash the block. It was quite unusual that it wasn't done when the perfectly new-looking VCM cam was originally installed by [unknown] What IS unusual is the cam that was installed there was advanced SIX degrees. As to why there is no way to know.. however it could have been @Dose Pipe Sutututu's mate who wanted a larger cam sound but also wanted it to come on earlier to be more usable. This is my dyno sheet with the previous setup - This cam is not supposed to peak until 7000+ RPM, according to VCM. This is what lead me down the whole 'my heads/intake setup is running out of puff and can't support the cam' line of thinking to begin with. Anyway too late now - New cam is in! It could be rather funny if this smaller cam acts like a larger cam because it isn't advanced six degrees. In the spirit of everything is working amazingly - the COMP cam required no dialling in whatsoever. It was about 0.5 degrees advanced, which seems pretty bang on. Any adjustment either way would be further out. I'm told as a chain breaks in it ends up regarding back about 0.5 a degree as the chain breaks in, making it bang on. In the spirit of everything was previously working amazingly - The timing gear that was taken out turned out to be was an N-Motion double timing chain kit, with adjustable cam gear (which is how it was 6 degrees advanced) and all looks entirely perfectly new. It also had a Torrington bearing, which was one of the reasons I ended up getting the Cloyes kit which they used in the C5R 24 hour racecar - Because I couldn't confirm what was in the engine when talking to Tony Mamo. I did believe however it was a Double chain kit of some kind... but found no supporting documentation or evidence for it.
    • I recently did this to my R33 with the full set from Car Mats Direct, they can't do the vinyl anymore that's advertised on the website due to a supplier issue so I ended up with the Black Loop Pile which looks great. I went all out with rubber sound deadening sheets from Repco and also added the sound deadening foam layer option with the carpet. Makes a world of difference and got rid of all the weird smells in the 29 year old interior. It was a bit of work but I'd 100% recommend it, Car Mats Direct had awesome customer service and quick postage. Replaced my seats with some sporty ones from Autotechnia while I was at it, feels like a new car.
