I did all the work on this S13 myself. I decided to build the KA24DE because of its large displacement, its iron block, and because it was already there.
To this date I've installed:
-Z32 N62 MAF
-GT28R Ball-Bearing Turbocharger (.60 Compressor, .64 Turbine)
-HKS Sequential Blow-Off Valve
-3in. Thick FM Intercooler
-Walbro 255 Fuel Pump
-370cc SR20DET Fuel Injectors
-Nismo Fuel Pressure Regulator
-Apex'i SAFC
-MSD Ignition
-NGK-R BKR6E Spark Plugs
-ASP Underdrive Crank Pulley
-SS Turbo Header
-XS-Power Dump Tube and Downpipe
-Apex'i N1 Dual Exhaust
-Auto Meter Boost and A/F Ratio Gauges
-Flex-A-Lite Electric Fans
-ACT Clutch
I have also adjusted:
-base timing to +16 BTDC
-max boost to 10psi
-base fuel pressure to 40psi
I have to update the pictures. I removed the engine cooling fan in favor of dual 12" FALs, installed an ACT clutch, and a Z32 MAF. I'm also about to install Tokico HP shocks and springs.
