I have recently chcecked haw much the stock injectors can handle. 0.7 bar is a maximum preasure on a T28 turbo with no fuel system upgrade except walbro fuel pump. It leens to 12,5:1 at 6000 rmp. The maf shows 4.95 volts and u cant ad any more fuel.

So if it maxes out at such an early stage how do the S13 owners manage 270bhp @ 1.2 bar?
It is worth noting that higher boost will result in higher fuel pressure so to some extent a reasonable fuel ratio can be maintained.

s13 ovners have 370cc injectors compared to 270cc in the s12's Yesterday i have instaled s13 injectors and remaked the MAF its now 60mm wide not mear stock 45mm. MAF that big will leen out whrew whole ragne of rpm's but will allow me to tune it more precise in the higher boost range.

The s13 uses the same air flow meter and that doesn't max out at 0.7 bar though. Its good for airflow up to 270bhp.
Worth noting that increasing the bore of the afm doesn't create a linear difference, but a logarithmic difference
