Alright guys so I’m not new to any of this just to the 2jz. I’ve researched soo much and haven’t really found what I’m looking for. Mainly just generically close. I bought a JDM 2jzge complete motor and wiring and stock ecu I believe out of a 01 is300. (Has coil packs)Was a auto. My plan is to drop the motor in a older Supra or a Toyota pickup,corolla,Cressida. Haven’t decided yet but all I’m looking to do is a mild 300-350hp build in the most modest simplest way. I have a Ebay manifold and a holset hx35 already. My biggest concern is the wiring. Should I swap to a 2jzgte ecu or should I keep the stock and use a midrange piggyback? I plan on running a r154 if that helps. Any which of way I need to go I would love to simplify the wiring in general. Just leave the basics. Researc research research I know. I’m about researched out! Just someone make it simple and straight forward for me! Thanks!
