    So i guess i should of said from the start but was avoiding it its a ebay turbo so i dont really want to push it too much because my luck itll **** up, maybe that might change your mind on the fueling or should i still invest in bigger? It is a ecotec

    Ok cool so ive seen that some people say that all the piping has to be the same length for the manifold, is this true? Ive got a design which will have 1 a bit shorter is that ok?

    At the end of the day its not a race car where you need to squeeze every last kw out of it. I would make them so its easy to work on the car. eg don't have to remove the manifolds to change spark plugs ect. just my 2 cents.

    Plenty of log manifolds and factory cars that don't use tuned length that are producing bucket loads of power. I somehow don't think you're going to reach the point at which it would make a difference with a China turbo and and a stock Ecotec bottom end with Ecotec compression.

    A little bit shorter is ok but how much shorter are you talking it can make one cylinder run a different fuel ratio than all the rest .

    Should be fine once you build a collector your plans might change on where the pipes go
