Brake booster question

[Phoenix7]

I'm looking at the FSM and they don't seem to be different in pressure (if I'm reading right) it says they all (NA and TII) create 312psi of pressure for 44lbs of force from our leg.

I left the stock GTUs booster for the TII swap and never had problems. A local guy has the Wilwood kit and had to disable the ABS because the fronts kept locking up in his TII. Dunno what kind of power you're looking to make out of the streetable 20B-NA though so you may need the brakes in the end you know what your needs are.

What did you upgrade the master cylinder with?

how far along on ths build are you? Looks like there are quite a few GTUs' on here. Don't forget to make a thread about your project.
