positive is the torgue by driving and pulling down the gaspedal
negative is that the gear and specialy the first gear is now short verry short

you have to shift fast otherwhise you get the engine running in what they say overkil? dont now the exact word
fuel consumption is messerated in metric from
4.3 > 100 km avg
to 5.1 > 100 km avg
but it`s probely my right foot and the big smile and showing of to other drivers that a small chevy (can) beat them

.overall good investment and relative cheap 300€
rest of the car/engine is stil factory
this engine is most common in opel overhere and there is a huge aftermarket for that brand
