Apexi Ax53b70

[libardi]

Hey guys ive recently bought my first R32 GTS-t, ive had a good look under the bonet and found this turbo (Apexi AX53B70). ive just had the engine though a compression test and it failed miserably so im looking for a new RB20, but i was curious if this turbo is worth while re-using or should i go for something different?

or can any1 tell me a little more about it?

so far all i can find is that the turbo is rated at 380hp for a SR20

cheers

Apexi turbo's are rare turbos nowadays being discontinued. That turbo according to my turbo chart is actually rated to ~320bhp. As a pair rated to 600hp according to nengun. http://www.skylinesaustralia.com/forums/in...st&p=980165 lists the turbos stats, trim size etc

it's a good turbo. keep it on the new RB20. you should be able to get a decent RB20 from a wrecker for $600 or so. the apexi turbos are a good thing. that size is a good match for the 20 too.

oooooo please tell me you bought my old car haha

are you in perth? does it have buddy club wheels and suspension?

awesome turbo, very responsive and will make just over 300rwhp

[SimonR32]

o yeah and if its my old car its rated at 380hp and its a AX53B70 P25

what were the compression test results?!?

I had one of these turbos on my R32, made 256rwkw on 18psi but that was on a rb25 and was full boost by 3200rpm. The tuner was impressed by the blend of response and power

[Bunta]

oh and dont over boost them! I upped the boost on mine and snapped the shaft...which is relatively common if you run more than 20psi apparently

They got ceramic turbine wheels. They snaps off at where the turbine wheel joins the steel shaft. Do not over boost those things. And its pretty interesting how they decide to sacrifice reliability for response.

Doesn't the Mspeed R34 GTR use a pair of these? Interesting if they have any issues with high boost.
