    CQ85 exhaust manifold OR type89 exhaust manifold

    The exhaust manifold on this 2.5 RE2500 (kv) engine has a type 89 version.

    will this match up to the 3 branch downpipe on my type85 CQ? or will i need to use my current manifold?


    Question two: if the type 89 manifold fits, what manifold has the best flow out of the two?

    To my untrained eye, the type 89 looks more 'ROBUST' imo, but the typ85CQ manifold looks more 'tubular' and less 'angular'.

    are there any 'flow bench' tests on this? cheers.

    Hey mate,
    The NG manifold will not fit the 3 pipe down pipe.
    I dont know about flow but i know that the KV manifolds are prone to cracking, hence the flexure in the NG manifold, which will not crack.
    I have the 2 Pipe downpipe from the NG off the car. If you need it drop me a PM just give me postage cost and ill send it to u??

    Alternatively, if your manifold does not have any small cracks, it may just be easier to stick with the KV stuff, saves swapping the downpipes, and plugging the Lambda hole.

    Any other questions regarding the engine etc, i'd be happy to help.

    Hope its going well.
