Fantastic car jsalova. A while back I was searching turbo and SC M110s and saw yours on youtube. I wondered if the M90 was too much, thinking an M45 would've been kinder to the engine, though perhpas on the small side. So it's great to hear that yours has stood the test of time. I can't imagine it would be easy to drive sedately, the temptation to plant the accelerator every time you go out, even if just popping up the road to get some milk, must be overwhelming
Koan mentioned your transmission and I'm curious to know if you've had issues there. I remember reading some fella's misfortune of going through a couple of auto gearboxes in a non blown W123 by just adjusting both camshafts by 4degrees advance, creating a huge change to low end torque. With an M90 and ground cams plus the rest of it, it makes wonder if there's potential for failure there. but then again, three years on and still going strong..... great stuff.
Saw that M119 transplant too Nathan.
