A thicker head gasket is an easy (but not proper) way to increase durability up to 0.8bar...It is wise to decrease the compression ratio down to 8:1 to be safe...But by decreasing the compression ratio to that number you get more turbo-lag..
The right way is to replace factory pistons with forged ones (custom made by any well known company ex. acralite). You can "order" them to give you a compression ratio of high 8:1 or low 9:1 to increase trottle response and decrease turbo lag....
the total cost incl. blow off valve, whole exhaust system -not only the downpipe- intake (taken from a lancia 1.6 or bravo 1.6), gauges bla bla bla ,is up to 5000Euros...
If you include forged pistons the price goes up by 1000Euros but the apllied pressure can be increased up to 1.3bar....
In addition it is essential to replace the stock gearbox with a stock punto gt one..2 screws need to be modified..I ve smashed 2 of them stock 1.6 stilo's gearboxes...:biggrinsanta: (4 gear is extremelly weak) :biggrinsanta:....




could you also give me the cost for doing the turbo conversion on the 1.6 engine [told you I will keep you busy didnt I :biggrinsanta:
