Hey. Forget about running a complete 7mgte under 5m electronics. There are many things that don't work, even the stock 7mgte injectors won't work as is with the 5m electronics. Remember, the head is completely different. Really, one of the mk2s biggest faults is its efi system. It works ok stock but it comes with a stupidly restrictive afm thats a PITA to get rid of, and there is no aftermarket tunning available for the ecu. No replacement chips, no rom burnging nothing, but there is that stuff for the 7m ecus. Now having said that, a 7mgte instill is alot more work then a 5/6mgte install due pretty much entirely to the wiring. Another option that is a better route if you dead set on avoiding the wiring is to use a 7mgte bottom with a 5m head, then you get a turbo spec bottom with your 5m electronics. You will have to buy new pistons however. But really, just do it right and go 7m all the way. There are people out there you can pay to make the harness for you, then its all plug and play and no painful and potentially dangerous tuning.
