I went to Nippon for my motor because of the feedback from numerous other mx6.com members who'd used them. I PM'd a few of them and got all their feedback and wasn't able to find 1 that had a negative experience. And as far as going to Corksport their prices were way too high for not a lot more. I have an eprom chip for the ECu so corksport would have just been a waste. As far as installing, I'm really glad I did it myself as that is THE REASON that my engine bay and engine look as good as they do. Hours of standing in the big hole scrubbing at all the hoses and painting everything. The only way you get your engine bay to look like mine is to pay some guy a couple grand or spend a couple days/weeks doing it yourself. It seems like a waste to go through all the trouble of swapping motors and then having it look like ass.Adaman said:just out of curiousty how many of you have dealt with a1? Hey dave why did you go with nippon? You could have gone to corksport for a few hundred more, and that even included a reprogrammed ecu?
