Are these motors any good?I am searching for the right motor and have sooo much to choose from,Axial spec 1s,Ofna Force,Dynamite,Picco,I have a stock Monster GT 4.6se,the stock motor finally gave up after almost 2 years ! I am stuck trying to make a decision on which to buy,I dont have a buttload of cash to blow,but I would like to have a reliable motor that will be easy to tune,and have more horsepower than my stock associated .28 any info would be gratly appreciated !
