I'm currently running a stage 2 hahn turbo kit on my 420a. I'll give the rundown of my setup.
Super 16g turbo
Stock injectors
Walbro 255
BEGI AFPR rising rate fuel pressure regulator (adjustable static fuel pressure and rate of increase)
Wiseco low compression pistons (don't know the exact numbers)
Forged eagle rods
stock ecu
Greedy Type RS bov
MSD coil and wires
EGR and EVAP delete
Autometer mechanical boost gauge
Autometer electric fuel pressure gauge
Autometer narrowband A/F gauge (doesn't tell me much need wideband)
I'm currently running 8psi which runs decent but sometimes sputters when coming on to boost slowly, maybe need missing link of FCD? I want to know how much boost I can run safely on the stock ecu. I know megasquirt is the best option but it's out of budget as for now. I know I need larger injectors but what are the largest I can run on a stock ecu? I have heard of 550cc working great but wanted to double check. I also need a wideband of course before any of this, which I am working on. Thank you guys!
