    Just picked this up a E30 Sr20Det because I had an itch that needed scratching I luv old skool Beemers and turbocharges so both together wot's not to like, it absolutely nuts

    But it's got a nasty vibration which i thought was the Lambda probe touching the servo, or its exhaust maybe gearbox mount but its definitely engine feedback.

    How much trouble is it to move the servo with the engine in ?
    Is there a smaller servo besides the clio or has anyone gone remote servo?

    im building a ca18 e30. I have gone the Clio route. with the std manifold all I have had to do it relocate the o2 sensor to the side of the down pipe instead of the back of it.

    did all my servo stuff with the engine in the car

    Did you move the servo over to the left ?

    I’ve built two E30 sr20det and on both builds I’ve moved the standard servo over these are some build pages on here somewhere that I did to show this also make sure the propshaft that has been made is balanced correctly matey

    Read your threads, nice work buddy very neat and tidy! The propshaft will be coming off as a matter of course to check it but the vibration is definitely something touching the shell its engine feedback.
    I thought it was the lambda probe hitting the servo as the servo has been smacked with a hammer to give clearance, that's why it needs swapping out and moving

    Right ok definitely move the servo over as it’s too close to the exhaust manifold for my liking you don’t want to be on full chat and you stamp on the brakes and it goes to the floor because it’s boiled the brake fluid or melted the diaphragm inside the servo also I move the lamda sensor down the pipe also to help with clearance as even once you’ve moved it over the sensor is still very close

    What engine mounts/rubbers have been used ?? I made my own mounts and used Mk1 Escort Mexico rubbers as the old bmw ones are prone to tearing under the force of launching the car

    From what i can see the mounts are here on the forum pre bought, tubular construction and very similar if not the ones produced by slide motorsport with the rubber mount between the two halves. The chatp said they were solid mounts but to me solid mounts are like the old MK 2 World Cup Crossmember mounts, just bolted straight in

    I didn't move the servo. I prob have a good 2" from exhaust to servo.

    I'm going to hear rap the exhaust and put a heat bag on the servo and master cylinder
