im finally in the position to get a 1jzgte (jzx100) with r154 for my is300 in which i plan on swapping in my vehicle next year. i have been doing quite a bit of research to gather as much information as i can before i actually do the swap in my car since ill be also doing a manual conversion as well. i plan on using the link ecu with the boomsling as well just for ease of use and tuning ability in the future. from my research i havent seen many people do this particular swap into their IS's and im curious to why. from what Ken Gushi mentioned in his video i should be able to use my stock engine harness from my GE on the GTE motor, does anyone know if that is true? or is that possible with the link ecu? ill be also emailing link ecu to clarify some things as well. any info would be great and i have read some and or most the post regard such swap but i cant find things that mention "i swap a jzx100 with r154 into my is300". i do plan on keeping this a living post once i get my motor to record the process as i go along with this adventure. ill just say this isnt my first time doing motor work since i have a fully built turbo integra (that i built) sitting in my garage. but working on honda's is crazy easy when compared to this or maybe im just trippin, lol!
