Looking into making my '01 Prelude SH-AWD. I need to do more research myself really but I thought I'd post up an inquiry into how the systems work, control module wise, power flow wise etc.
I'm looking into using the J series 3.5L V6 and the SH-AWD drivetrain from an second generation KB1 chassis RL.
I'll have no problem pulling the project off, its just a matter of money and info I need at the moment. I'm looking to create the best Prelude I can given I have a salvage KB1 Acura RL, creating a sort of RL/Prelude frankenstein.
I know the SH-AWD system can send as much as 70% of the power to the rear and up to 100% of that rear power to the outside rear wheel.
How does it operate under normal driving? I know its mainly FWD but whats the power distribution front/rear?
Is the front differential open?
I will likely go supercharged with a rotrex, would it make most sense to run the motor on a stand alone ems?
What computer modules run the SH-AWD system and how do they tie into the engine ecu and body modules?
I'm likely going to want to run some custom electronics that will allow for different programmable settings for the rear and center differentials, does anybody have details on how the internals of the modules work or what parameters/sensors /ins and outs there are?
What are the harness layouts/connectors for the engine harness, body control modules, transmission control modules and SH-AWD control modules?
Does anyone have access to technical data or repair data for the RL? Schematics/Pin-outs etc.?
Heres what I'm expecting to use from the RL:
If I use this I will modify the subframe and/or body of the Prelude to mate the two and likely run RL springs/shocks along with fabricated mounts for RL upper control arms.
-Power Steering Rack
-Rear Suspension/Differential Subframe
-SH-AWD Rear Differential
-SH-AWD Automatic Transmission
-Transmission Control Module and Wiring
-Paddle Shifters and Wiring
-Gauge Cluster (For retrofit into the Prelude)
-Front and Rear Brakes (Aluminum 4-piston Calipers with 12.6" Rotors and Aluminum 1-Piston Calipers with 12.2" Rotors)
-Front Headlights (For retrofit into Prelude w/ or w/o Active Front Lighting System) HID Projectors/Ballasts/Bulbs
Any input/advice/info is greatly appreciated, I'm looking to find that 5% of people that have alot of experience with RL's and the SH-AWD system or maybe your new to the scene and have nothing to add but want to follow along on progress, either way, thanks guys.
