Ive been deciding between a quality stock rebuild (apparently the closest quality rebuilder is a whole state away), A jasper remanufactured (cant find any real reviews/experiences with the 2F), and A MAF Hi performance rebuild. I have searched here extensively and havent really found any amplifying info on the MAF, except for the fact many people hate Man a fre for their lack of customer service. I have read the article on Pirate 4x4 about that one guys bad experience with his secondhand maf engine. It seems many people wont differentiate between MAF and the people (Martin Davidson?) that do the engine rebuilds. Martin Davidson, from what ive read, seems to be very familiar with the 2f and know what they are doing. I have talked to former ARB rep Chris wood, and he has nothing but good things to say about his engine. I have also talked with Albert at man a fre (responds within 24 hours every time) and he says he has customers with over 150k on their rebuilds. I know a machine shop can do the rebuild cheaper, and i understand i will have to run premium fuel. Im fine with that. Im just stuck between a rock and a hard place. I really want the ease of a dropin rebuilt hi po engine, but the couple bad reviews have me second guessing myself, however i do know that complaints are louder than praises on the internet- and ive really only read 2 complaints (on the engine). Does anyone have any amplifying info on this engine, hard facts, or experiences that can help sway me one way or the other?
