You can use the P12 CAS or the Mazworx sensor and a solenoid relocation kit to work on the RWD bottom end. This has been done many times in several RWD applications. You also need to use the VVL metal head gasket with the VVL oil pump with a modified pickup.
I like this build. The SR is a great motor, I've been messing with them over 20yrs. and still feel they are one of the best motors out there. If you ever feel the VVL version you would fall in love.
Keep up the good work.
My brothers all had D-slots on their 510s back in the 80's but I prefer the look with the Panasports.
I always liked this car. Whenever you google 510 wagon this car shows up. I have it as my screensaver as an example of how our goon should look when it's done.
I like the fit of the panasports with the stance.
Have you tried to put the RWD tranny on there yet?
The bellhousings are totally different. I work on both engines all the time. The flywheel, clutch, starter, motor mount, oil filter location, water hose locations and bolt patterns are different.
Internally they are the same but the castings are different.
