So I've done my research and figured out that when building an FJ20, the best thing to do for low power is to get a set of S4 Rx-7 turbo injectors, but as is the case when building a car, they showed up and something's wrong.
these pictures should illustrate:
stock:
new:
and the hole that they have to fit into:
so as you can see, the gap in the intake manifold is 9.8mm diameter, but the width of my new injectors is 10mm. Theres a counterbored hole above the 9.8mm one that the O-ring sits in, so what im thinking...
Should it be fine for me to drill out the lower part of the hole to 10mm as long as i leave the top part the same so that the O-ring still fits?
Cheers.
