Guest VTI-S Posted September 6, 2009 Share Posted September 6, 2009 Hi everyone, I would greatly appreciate you sharing your knowledge with me:DC2 Type R Stock exhaust manifold onto a B18C41) Is the above a cost effective upgrade for a B18C4 ?2) How does it compare with other manifolds?3) Believe it is 2.5" and a 4-2-1, is that correct?4) Obviously I will need a custom cat etc. - roughly how expensive would that be, in anyone's experience? (I'm not being lazy with this question, I just need to make sure I'm not being ripped off)(Sorry if this post is in the wrong section), Many Thanks Link to comment Share on other sites More sharing options...
Moe Posted September 6, 2009 Share Posted September 6, 2009 the ukdm manifold is 2.25", the 96 spec jdm is the 2.5" 421 and the 98 spec jdm is the 2.5" 4-1. the 98 spec jdm is a very good manifold and cost about £250ish depending on condition.the b18c4 manifold had a smal collector so going bigger will usually benifit it Link to comment Share on other sites More sharing options...

Guest VTI-S Posted September 11, 2009 Share Posted September 11, 2009 I just won a DC2 Type R UKspec manifold for £55 delivered off FleaBay. Seems good condition, no dents/scratches.Is this the going price? Have I been ripped off?I needed my exhaust changing anyway, so thought it would make sense to change manifold at same time. Might go for two tailpipes, one either side. Link to comment Share on other sites More sharing options...
Moe Posted September 11, 2009 Share Posted September 11, 2009 that seems about right. its the JDM ones that are a bit more expensive Link to comment Share on other sites More sharing options...

The only other mod I currently have is a K&N, but have got a full SS exhaust & decat planned as well.Also, is my stock B18C4 manifold a good upgrade for a B16 engine? Thinking of putting it up for sale to our 1.6 little brothers on pistonheads or something.Thanks Link to comment Share on other sites More sharing options...
Moe Posted September 22, 2009 Share Posted September 22, 2009 Every car is differant so cant really say how much power you will gain or lose. The B16's use a a cast iron manifold were as the b18's use a tubular one, so there might be a gain even the slightest, plus its alot lighter Link to comment Share on other sites More sharing options...
