Which EJ engines will drop in with little to no modification required? Will any NA EJ22 or EJ25 drop in without modification or changing the ECU or wiring harnesses? What I have learned so far is that the difference between early years EJ22 and 97+ are that early models have HLA, are non-interference, and have dual port exhaust. 99+ have revised blocks and heads. Swapping y-pipes should not be a big deal, so will an early EJ22 swap in without changing anything else? Because my bro and I live in Cali, swapping in any engine older than the model year of the car may be a problem. I also heard that EJ25 may drop right in and work with the factory EJ22 ECU.
Somebody please break down which NA EJ motors will be the easiest to swap in and which modifcations will be required to do so.
2nd part of this question- Where should I look for a motor? I called Japanese Engine Importers and none so far can get me a 99 EJ22, but they are willing to sell me a rebuilt long block for $2k.
