Hi all.I am about to put a apexi ax53b70p25 turbo on my 33 with a tomei fuel reg.Cant afford new injectors or afm for at least another year due to having a mortgage and two infants.Do you reckon ill see any improvevement over my current setup of stock turbo,powerfc,front mount,fuel pump,etc.Currently running 260hp at the rears on 12 psi.I kmow the turbo will thrive on bigger injectors and a z32 afm but it is not an option at this point in time.

It'll be an improvement until the AFM runs out.

You'll make around 210-230rwkw or so without having to change out the AFM once you get it retuned.

AFM/Injectors tend to run out pretty close to each other so you might find it might be around the same, if not as you said you have the FPR just in the interim~!

i made 250rwkw on 16psi with this turbo on a rb25, with 55cc, z32, etc.. great response but the actuator stuggles to hold boost above this..

i also made 220rwkw on a rb20 with this turbo also but was somewhat laggy.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
