Is it worth trying n/a mods like porting the head, cam and exhaust extractor and if the parts are relatively easily sourced.I have a 95.5 mm stroke crank that I have had lying around for the last 10 years ,hence the normally aspirated route.Going Turbo... fair bit more to source and replace?.
Anyone's thoughts.
Its not worth wasting your time with an na engine when there are turbo engines available.
Easier to just get a s4 or s6
Your timing is good...manual s4 that might be up for sale soon
