    Hi guys. I am about to go down to the scrappy this week to hunt for a bigger throttle body for my M50B25TU block. My plan is to get a throttle body of something like an e34 530 to 540. But Im not sure wat body would fit my manifold and not require a remap after. course a remap would be good but the ecu would be able to adapt to a cirtain point as far as i know.
    what are your views on this?
    What I also was thinkin of is to get another m50 manifold and bore the inlet out to accomidate a larger size body. any ideas?

    Cheers guys

    While being on this topic. Could anyone explain to me what the coolant pipe actually does that passes throught the Throttle Body housing?
    In my eyes, I see that the temperature of the air is measured by the thermostat in the air box and then if the air is too cold, the coolant is passed through the TB to warm up the air going in to avoid the chance of a lean mixture thus avoiding engine damage?
    Am I on the right lines? Anyone know this?

    Cheers

    Stops the TB from freezing up in cold weather. Probably not needed in the UK but that's up to you to decide!

    yea, sounds like a reasonable explanation. But been talkin to RicerRocket mates and his 350Z has the same stuff to an extent but aparently its to prevent ice paticles in cold air from going into the engine.
