I just went through your whole thread as I am stock piling parts for my RB25 swap. Thank you for all the time you put into this! I will definitely use this as a guide.

I'm going to shoot you a PM regarding that package deal. This method seems a little more intense which i dont think i can handle. I'll stick with the AEM S2. Let me know how it works out. I have to look into the CAS disc, i hadnt heard of the need to replace that. I hope there is nothing else that would have to be done.

I would like avoiding that $1700 expense but to my understanding you have to go with a aftermarket ecu if you plan on getting more power out of the rb25. Can the stock ecu be tuned? I plan on at least swapping out intake manifolds and exhaust manifolds so I can run a top mount. Would I be able to run the stock ecu with those upgrades?

So I'm thinking about getting an AEM s2 but get the car running with everything bone stock. Is that possible? I'm thinking I should do this since I do plan to make upgrades in the future but I don't want to have to swap ECUs and mess with the harness in the future( I'm planning to buy a wiring specialties pre made harness) I plan on upgrading injectors and manifolds and turbo so I can run a top mount.... BUT the money isn't available for all that right now. What do you all think?

I wouldn't trust anything other than McKinney mounts. Everything else you can opt to cx racing, I wouldn't cheap out on the mounts. They're too important. I actually ordered my McKinney mounts, driveshaft and throttle cable last week.

I thought the lights were all connected to the ECU together with the engine harness. Is that not correct?

I have a tranny off of a turbo 280zx. I'm not sure if it's good or not. Got it off a car that wasn't running.

Thanks for the info buddy, it greatly helps. I'll most likely go that same route and try and find a shop to wire up lights and stuff.

How do you like the pre-made harness? I assume those are literally plug and play. I was comtemplating going that route to keep things a little cleaner. The car is going to be a show/weekend car so I need to make it street legal. Head and tail lights are a must for me.

I've been a long time lurker of Hybrid Z and now that i am looking into doing an RB25DET swap into my 280z it's time to introduce my self. I have a 77' 280z with some minor cosmetic modifications (flares, low, wide wheels.. you know the basics. Now it's time to work on the motor, but i need some help. A lot of it! On to the noob question... If the OEM ECU is replaced with the RB25DET ECU how does the wiring for the headlights, tailights ect. work? Is the wiring harness for all that separate from the engine harness? This picture below is telling me otherwise. I am relatively mechanically savy so i will be attempting to do all the wiring harness using the great info from this forum's members. I'm trying to gather as much information as i can before jumping into this. Any help is greatly appreciated!
