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.

Sure do, If you buy new you get al the lines you need too! Unfortuneately I bought second hand and I am missing two water lines. But for what I paid for it I dont care!

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
