1jz-gte swap in 87 supra

I'm going to break my own rules and just answer with "search". This has been covered very well in the past.

I believe the 1JZ-GTE is missing the EGR system and is tuned differently than a USDM 1JZ equipped vehicle would be. Technically, if they know what they're looking for you'll never pass quite simply due to the lack of the EGR system.... but you'll seldom hit a tech THAT thorough and knowledgeable. Just install the system as close to stock as possible and in the worst case if you fail emissions you may just need to add a fuel controller and tweak your ignition timing to pass. It shouldn't be a big ordeal though or you'd find a lot more info about it when you search for information on the swap.
