Janspeed exhaust

Post by Spud » Sun Oct 28, 2012 10:54 am

Hey everyone I have quick question, i have just brought a full janspeed exhaust for my vitara but I forgot to check if it will fit mine I have a 1.6 8v and the listing just said it was for a 1.6 so my question is does the 8v and 16v engines have the same manifold size and exhaust fitment??

You may be lucky as I can't find a Janspeed system for the 16v, so hopefully they only made it for the 8v ??????????

Looking at the manifolds, I'd say that the 16 valve manifold is much better port matched and looks like it's a higher flow manifold in general so probably wouldn't need replacing unless it was for a stupidly tuned engine, in which case the manifold would cost a fortune.

The 8 valve manifold on the other hand is far from port matched and would have bad flow characteristics for cylinders 1 and 4 so I can see that being replaced for a better one just for general use.
There's three ways of doing things:

The right way,
The wrong way
And my way, which is like the wrong way but faster.
