as said cossie engines aint cheap but how reliable is that zetez doing 9's and how much work money has gone in to.
keep a cossie at stage 2/3 and you will have no problems with it provided you have right cooling and oil issues addressed.atmo cossies i know of a few atmo cossies that have shit them selves on lots of occassions but they are not aways talked about,zetecs wont give huge power etc imo althought for 170hp are cheap to replace if they pop.i can see the duretec standing the test as still newish and already hitting near the magical 300(some over if on the right rollers haha)pintos and crossflows have been around for ever as well but if built right make very good and very reliable power.look at tobys,ht racing,hpe,aston etc.horses for courses still.although all the atmo boys love talking about the blowing up of the cossie turbos.a duretec is my next port of call for sure
