OK, I have just read all 13 pages of this thread..........and here's my .01 worth (probably not even worth .02). There is a lost variable that has not been directly mentioned. You can't just swap the motor! There are gonna be many more issues to deal with making a different motor mate up with your car. These will all add to the cost. I admit, I am one of those "never layed eyes on a 1J" guys. I will probably stay 7M for the simple reason I am not in an endless HP spiral, and will be happy with 350WHP or less (I think). Hopefully I will at least get to see some 1J's as I plan to start making it to some of the bigger meets.
Ideal..........wouldn't the 50HP and 4-5lbs of boost be solved by simply adding a BIC DDP. And, is the stock 1J 280HP at the crank or wheels?
As for Bigaaron...........If you people want a 1J, and don't have the confidence to do it yourself........take your car to Bigaaron
