I agree with everything said, im doing this conversion to a drift only car, never will be registered so im not worried about down time, dont need everything working (like speedo).. this has just been a learning thing... going to a v8 would have been a lot easier then mucking about with all the electricals though.....
So far im running the rb20 looms and have not changed any pinouts however i have read that two pinouts on ecu for injectors needs swapped which i havent looked into yet, however as mentioned a lot of useless info out there. also a lot of good info so ALOT of research is needed.
