Yeah W11's are 8CW cranks while RR is 4cw, the pulleys are slightly different, but they still might work. I'm worried about my RR crank separating too, we get crank pulley separation on Subarus all the time, I switched to a solid aluminum one for that reason. Too bad all of SR20 options are super light weight and underdrive it, the light weight is the real issue though.Ok. Mainly the crank pulley. Only thing I thought of just now was that's a W11 DET. I have a Roller Rocker with a T25. Pulleys are different I think. I pinpointed my crank pulley having separation. Thought it was Ps pump cause the noise reason I found steering rack leaking lol.
The steering rack on mine has 130k miles on it, I've always used ATF (like cap calls for) so it should be fine for a while long. Biggest issue is people using off the shelf power steering fluid, which destroys our seals. I ruined my PS pump, PS high pressure line, and steering rack seals on my G20 by using off the shelf power steering fluid, I learned, now it's ATF only! :-D
