Hey,

I was just wondering if anyone knows much about apexi turbos? I just found (after 6 months owning my car), that I have an aftermarket apexi turbo!! I never noticed as it's a low mount, and tucked away behind heaps of stuff! :/

Does anyone know whether they are a good turbo or not, compared to the likes of Garrett etc.

I'm trying to find info on apexi turbos but i cant find much at all.

Any help would be appreciated! :D

You must have thought that the stock turbo on the R33 was pretty good!! It sounds to me like it would be a AX53B70 P25, I have one of these to go in my R32 with an RB25. I have not fitted it yet but the previous owner made 236 RWKW on only 12psi!!! The only other result I have seen from an RB25 is 268RWKW at 1.2 bar (But stay tuned mine is going on in around 2 weeks :D ) . I was told when I was looking around that this turbo is roughly equivelent to a HKS 2535 but in reaality it seems to have better response and a better top end. So in short yes it is a very good turbo! What other mods do you have cause your car should be obviously faster than a stock turboed car!!! I will attach some pics of my turbo (May help with identifying!)and the dyno graph from the old owner!

Holy craaap thats awesome! :/

When I bought the car (from a private importer, i'm the first aus owner) the guy said "yeah it's got a stock turbo in it"

Other mods that came with it:

Apexi Power FC + Controller

Apexi Boost control kit for PFC

Apexi GT Spec Intercooler

Apexi Strut braces front+rear

Apexi N1 Spec Coilover shocks

Apexi Exhaust

I got it dyno'ed today at UAS at 185.2kw @ 0.9bar, and the guy said "Its in DESPERATE need of a tune (like 13-14 AFR all the way thru the range.. waaay too rich)" He also said "Has it got an aftermarket turbo?" when I said no, he said "Are you sure!? cos you have a VG30 Air sensor on there... plus different IC piping, so it looks like a bigger turbo has been on there at some point!" Hence, why I decided to look!!

I cant see the red tag unfortunately.. I wont be able to see it unless i dismantle half the engine bay! I may just do that for peace of mind

Thats great! what a bonus! Haha

I'm gonna get it tuned and boost it up then!!

Well bunta I hope all goes well, good luck with the install. please keep me posted on your progress! :D

Thanks for the info

do these turbo's fit up to the standard exhaust manifold and dump pipe flange?

my mates r32 rb20 came over with this turbo (ax53b70) and a stock manifold and stock dump/front pipe so its a direct bolt on 380hp turbo.

    • Each province differs a bit but we only do mandatory vehicle inspections here for heavy vehicles (Think Ford F350 and up). Those inspections are done by mechanics that are approved by the government. Besides that, it's a free for all as long as the car looks stock.  I asked because I love seeing how engineering differs from country to country. Here in Canada, all designs must be stamped and signed before they can be brought to fruition. (I.E Bridges, structures, Electrical panels, machines, literally everything shy of a wooden table) This can only be done by a professional engineer or professional engineering technologist. Both are protected titles, but the latter having more of a limited scope in what they can stamp. To become a professional engineer, you must complete a 4-5 year bachelors degree in your field of engineering, be part of an engineering order and undergo 4 years of apprenticeship, testing and mandatory continues education. Same story for engineering technologists, but a 3 year associates degree in some form of engineering technology will suffice. If you do not comply, or pretend you're an engineer or technologist, off to jail you go. If you stamp a design that fails, off to jail you go. If you stamp a design that fails and kills someone (I.E Bridge collapse) Off to jail you go for a very long time, your family will be ridiculed on the news, neighbours will surround your home with pitch forks and your dog will disown you.  Same for specialised trades... Example Electricians must undergo 1.5 years of post high school education, 4 years of apprenticeship, testing and hold proper licences. It's for the best, but then we also wonder why we're so short on engineers and tradesmen haha
    • Not currently, I'm at the school where we teach people to build bridges and other fun things that involve making, or breaking things
    • I have a friend who has used Chequered Tuning and CMS. Went to CMS when Chequered had a long wait time which is kind of the norm (for good reason). Was very happy - I'm pretty sure the very simple thing you're asking will be simple.
    • lol that caught up a year quickly! good to see you on the track again, hoping to do it myself one day
    • Nah he was mega organised, the sort of guy that put (almost) every tool back every day, it made trying to work out where things were up to possible.  My shed needs a swedish death clean, I would have >20 part done jobs, its particularly hard to collect all required parts for a job ahead of time when you can't just pop into a shop and grab things
