Title: r-tech question? porting exhaust manifold pre remap
Post by: blade4real2004 on 12 February 2012, 14:20

hay nick just a quick question are you able to explain what needs doing to the exhaust manifold in detail for porting for a k04-001 upgrade before the remap?

The collector needs cutting down by around 45% and the runner on number 3 needs to be enlarged.  You just want to make it flow better and get rid of all the sharp edges ect...

I dunno.... :laugh:

Its a case of good judgement...........  so I took sh@t loads of mine and it held up fine for 300bhp and closer to 400bhp with NOS and no nasty cracks..
