WHOSYA DADDY WHOSYA DADDY!!! LOL sorry...couldn't resist that one... :{D
anyway.... Welcome to our happy little corner of the net, and to our Club. There are TWO BIG fridge'S in the corner with anything you can think of in them...help yourself...of course only take what you can LEGALLY have. (stash)
make yourself at home on one of the big fluffy couches, kick your shoes off, put your feet up on one of the tables, yes we are allowed to do that, mom don't care....and take it easy.
oh...btw....every once in a while a food fight breaks out...so you may not want to wear nice clothes here.
Welcome!! (stash)
as for your questions.....YES you CAN squeeze a 19 in there...but OMG the sidewall is a tiny thing.....its like riding on rubberbands, as Miss Mazda mentioned....get ahold of Rishie...he can give you the specifics as to what will work and what won't.
As for a Turbo....well you can expect to end up putting out about the same HP as the Mazdaspeed Pro with a mild turbo setup....pushing about 6-7 PSI....check out the forced induction section, there is lots of good information there.
