Since your Fuel Pump is broken adi, best replacement choice is either one from of the following cars:
Celica ST 3S-GTE
VR4
4G93T GSR


Now that u have the fuel pump sorted out:
Fuel pressure for 4A-GZE should be around 36 to 38PSI for Daily use and above 40PSI for COMBAT MODE.

Fully modified 4A-GZE for racing purposes should use 45PSI to 50PSI (if the injectors are not upgraded). BUT if you change to bigger injectors, lower pressure (below 45PSI) will give better results or else you gonna flood your engine with unburnt fuels.

Hope this helps.

My 20V uses 4A-FE Fuel Pump all the while and never had any fuelling problem (on the road and on Track). So imagine using 1JZ-GTE for 20V, it's like feeding a baby with milk using baldi hahahahaha. But the key is to have proper sized Fuel Line and Return Passage, and proper pressure. Bigger Fuel pump need lower pressure.

Hope this helps.

Mazda RX7 turbo (FC3S)
Toyota Supra (MA70,7MGE/GTE)
