I do run the N21-5T but I do modify them. Out of the box it is already a good engine and after some modding they are as good as any other more expensive engine. The basic engines are made a bit slower through timings, a smaller hole in the crankshaft and missing optical things like a silicone insert.
Roelof i understand you exactly.......
. I need my friend some pictures of your modding. Really if it possible i would be grateful.
About the differences i realised that there is somewhere fake specs on behalf on NOVA.
I mean it is not possible to add at a basic engine some exotic materials and technologie of NASA and still it produces the same HP and RPM.
Something else that i realised is that the expensive motors have installed carbs with single needle on the contrary with basic engines that have two needles.
Could someone explain me the the benefits pastic vs aluminum carb?
