Kevin Bacon 5 Posted April 10, 2003 No you just need both halves of the 50mm manifold. You would be wise to replace all 4 brass injector seats & seals, the 4 plastic guide tubes and all 8 injector seals whilst the manifold is off as they are prone to leaking and the plastic tubes usually break with age. You'll find the engine pulls harder to the redline with the bigger manifold, at the slight expense of bottom end torque. Kev 94 Corrado VR6 Quote Share this post Link to post Share on other sites
