is it worth getting a pm70 ported as i have just done a fresh rebuild and fancy trying it ....it has just over 13bhp on the dyno how much will it make a difference
Plus you question is worded really badly. Are you asking if you should get someone to port it or should you give it a go? Either way it normally makes more sense just to buy a more powerful kit when it comes to 70's.
you can port a polini sport to corsa type performance if your handy with a dremel.... and have the right set up
