1.6 CY engine, mechanical head, little porting with bigger valves. VNT20 with tube header, 2,5" exhaust, gasser intake manifold. 10mm pump and 28psi (1,9bar) boost. Pictures are couple posts above. This is pretty much all you can get with 10mm pump. Dynoed today. 151hp/286nm at wheels. That`s ~165 crank hp
I've personally seen one run for more than 5 minutes at 161hp. The head is certainly not the weak link, rods maybe, but not the head.
There are factory TDI 1.9 engines that make 150hp in Europe.
