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 ) . 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!
I must admit that if I was looking for a park and somone had parked across two parks I would be pissed, Of course I wouldnt key the car but damn it is almost an open invite to people of low morals
It is nothing to worry about, as long as you dont mind the soud it is fine! It is to do with the design of the core or the piping, Almost all of the older ones whistled though someone told me the newer ones didnt as much
I guess the hybrids didnt get the nickname "the Chineese whistler" for nothing, It is ghey and annoys me (Came with my new car) and I will be changing it to a better brand! The HKS cooler on my old car never made funy noises!
