In about a month or so I am going to do one or the other. I absolutely HATE this POS T45. The only positive thing is that is hasn't broken yet. I am trying!!! I have driven a 01 with the 3650 and there is a WORLD of difference. I mean night and day. Smooth as silk compared to this clunky POS. I have a buddy who can get one real cheap and will put it in. I figure around a $1000 for everything. Or I can get the heads ported for around $600, another $500 or so for the labor to swap em, then I am gonna need a cam re-grind which I believe is around $250??, then 24 lb inj. and re-tune. So probably around $1500 for 30 or so rwhp. What do you guys think I should do?
