After much thought on what to do with my SC400 engine-wise, I have decided to pull the trigger on a 1GZ-FE to make an SC500.
Jimmy at JPR Motor Inc. recently had a 1GZ in stock but by the time I decided to go for it, he had sold it about week earlier. (I bought a RX7 Turbo II swap a few years ago from him and he has always been a good source for quality JDM engine/trans parts) Thankfully, Jimmy was in Japan last week and found one for me some 3 hours north of Tokyo. This one is coming with the trans, wiring harness and the two ECU's and should be here mid April.
Initial plans plans are to swap it in bone stock with the auto trans and try to keep the stock intake manifold setup. It appears to be dual mode (intake flapper valve) and I have seen these good for 30-35 ft-lbs. on IS300 2JZ VVTi's. I do not mind getting a custom hood made but we will see how much room there actually is to determine which way I go on it.
Engine management wise, I'll be using my existing AEM Series 2 EMS and a custom harness which will allow me to run the engine sequentially for fuel and wastespark for ignition. (it looks like it has two sets of the 2JZ VVTi coils and igniters so is wastespark from the factory) I will also be controlling the trans through the AEM and will be retaining the DBW throttles using a custom AEM DBW controller. (I designed the DBW controller on AEM's STi plug and play ECU's when I still worked there and had the forethought to design the controller for use with 2 throttles, glad I did that now) And, of course, controlling the VVTi.
Later on, Stage 2 will be the installation of a Getrag 6 speed, Stage 3 will be adding a pair 3076R's. (most likely) Stage 4 will be a fully built motor.
Overall, I can't wait to hear how this thing is gonna sound.
