Thanks! There is more info than what I have in my notes about the EJ hybrids but what I just posted is pretty much what I have been able to collect from my notes & from other builds. I'll do what I can this coming week. Phase 1 USDM stuff doesn't have much to be tossed around. We only have 3 types of EJ25Ds & 3 types of EJ22s as opposed to about 20+ other EJs that exist in other countries, so I don't know too much about them.Originally Posted by chuckthefuk
It isn't hard to convert a 22T block to run on OBD2.Originally Posted by couchfuzzy
If you're putting 97-99 25D heads on the 22T, you must keep your wiring so this will mean keeping the 25D knock sensor (since knock sensors for DOHC & SOHC are different) & retaining the 25D wiring harness.
Cam & crank sensors are all the same & so are the crank gears.
All you have to do is swap over all of your 25D stuff to the 22T & it will run, without throwing a check engine light if you do everything correctly.
Keep the 22T water pump but get an 11mm oil pump to ensure that the heads & crank get oil at all times.
Also, get a piggyback ECU, more aggressive fuel injectors, & better fuel pump to compensate for the extra air pressure from the turbo.
