i just bought a mp45 all in one sc and intake it has a 2.6 pulley and how big of injectors should be used it has some lsj but i think they are high imp and i need low imp. i have a 96 2.4 ld9 z24 a 255 walbro will be enough for the fuel? i was doing turbo but switched to sc what needs to be done to the evap system? it also has rsm 62mm throttle bodie and stock pulley.plan to meth inject and possibly add my n20 kit before thottle bodie. how does one switch over to 97 ecm and run hpt? thanks

Part number for 97-99 Cavalier ecu is 16228016. There are always a ton for sale on ebay. You'll also need the wiring harness. I was able to get mine off ebay, but I think that's hit or miss. Check your junk yards. The walbro 255 should be fine. I'm ordering part number 25163473 today for my fuel pump upgrade. It's basically the same output, and it's a little cheaper.
