The Novarossi N12T1 now called the Sturm is a good and very affordable engine. With the .21 clas they are running the Novarossi ISON21 as stock engine but that same Serpent fanboy is now an OS fanboy and wants to add the new low budget OSMAX R21 on the list. I wonder if OS is also comming with an .12 low budget version.
Roelof, I do not know where you get your info, but the issues some had with the .21 picco based pss engine do not translate to the .12! We have run it together with the nova sturm in this years national championship and found no issues at all. If anything I have had less with the picco than with the Nova!
Also the bottom end of the picco pss is quite a bit better than the Sturm. Although the latest batch Sturm has a revised crankshaft which improves the bottom end a bit.
To summarise. As an engine to learn your car, for practice and even for racing, both the sturm and picco pss are very well suited. There are some offers on a package for sonic pss with pipe combo for around €220. Which is very good value for money!
