    Default ST215 manifold/throttle body in 185

    ok guys I may have a st215 manifold and throttle body but I have a few concerns.
    can the stock throttle cable be made to work with the 215 throttle body?
    can a gen 3 tps be used on the gen 4 throttle body?
    is the plug for the ICV the same as gen 3? (as I cant get a wiring loom or tail so need to use gen 3 stuff.)

    other option is use a gen 3 throttle body and sensors.
    my concern here Is it opens down instead of up so will this change the flow of the manifold greatly?

    what have people done?
    cheers guys

    you can adapt your gen3 TB to the caldina side feed intake .. There is a slight difference in the gasket - and face but its not hard to modify ..

    For a St205 , you can just use a caldina throttle cable - and just swap over the backing plate that attaches to the firewall ( where the cable pops thru ) the distance dofference shouldnt be that great a difference between 205 and 185 , though i can see you needing to tweak it up a little more than just bolting it up like i did
