Quagmire Posted September 3, 2008 Share Posted September 3, 2008 Has anyone got 3.9 manifolds from a Range Rover or Disco on a 3.5 in a 90? Are there any clearance issues if i use these, and is there actually any palpable benefit over the older style 4into1 manifolds? Just working everything out before i do the conversion.

tacr2man Posted September 3, 2008 Share Posted September 3, 2008 I have a 3.9i in my 110 with the efi manifolds, no probs, it was a v8 3.5 from the factory , so dont know if that helps you was yours a factory V8 90 ? Its a job to say if they help re power to any extent as the engine was more powerful anyway. Whether its worth the hassle with a 3,5 is debatable. A proper multibranch manifold in stainless probably would be JMHO HTSH Quote Link to comment Share on other sites More sharing options...
Quagmire Posted September 3, 2008 Author Share Posted September 3, 2008 It is a 2.25 from the factory- the 3.5 is currently being built to go in sometime over the next month or two. I have later 10 bolt heads to go on the block, and as these are more free flowing (bulleted valve guides, wasted stem valves and larger ports) it would be a shame to strangle them with an early exhaust if the later design is better.

paul stage1v8 Posted September 4, 2008 Share Posted September 4, 2008 I am using the 94 disco front pipes and manifolds in my 110, but had to use the disco crossmember to get clearance for the front pipes, they tuck up nicely between the chassis rails Quote Link to comment Share on other sites More sharing options...
