I dont have time to reply right now cause I am at work but I will when i get a chance later. Some of the comments on this thread are accurate, some are relying too much on what magazines say, and others is just plain ignorant BS. But it sure is funny to watch and see someone make such a comment to the affect of "Yeah sure I can build a new custom turbo system for under $3,000. lol. And then it seemed like they thought that they didnt need anything like a higher flow fuel pump, or bigger injectors, MAS tuned for the injectors, or reprogrammed EEC or chip, Let alone new built tranny if they planned on running fairly high boost. And we havent even dug into the engine itself if ya want to go that far. One thing i dont like to head is the whole buy a race car instead of trying to make an explorer fast! I say to each his own. And my take on it as I am sure what Bill & Dan Rotolantes and Dominics are is that we want something different. Most of us already own fast cars. We also want a sleeper fast truck too. To be able to ride around in comfortably and eat the occasional cobra or SS that comes along. I just hope that before anyone starts a project they take whatever they think it will end up costing and the time it will take and take those numbers x at least 1.5-2. Cause that is most likely where it will end up being. Heck it cost me a little over $6,000 for my supercharger project when i had my 2000 5.0 explorer, and i hadnt even got the chance to buy the locking rear end or the higher stall T/C. That would have tacked one another $1,500-$2,000 depending on if i went with TCI or Precision or such for the T/C and if I went with an Eaton electronic locker or just an LSD. Oh well i guess I kind of did get caught up and replied anyways. This stuff is really really really fun and very addicting, at least it is for me. But you had better have the mindset, knowledge, patience and money to make it all happen or you will turn out to be another one of those guys selling their half finished project truck on ebay for half its worth.
