so far i love working on mine..dont regret anything at all...ive already dropped the tranny twice, installed timing belt and water pump just to name a few.
The most frustrating thing i ever had to do wasnt on a mr2
i was helping a buddy replace his timing belt on a 420a on his eclipse and to get the passenger side motor mount bolts out to remove it you have to either drill holes in the frame or drop the motor.
and being on the side of a highway in dallas i have to cut some corners
Now it has a shiny hole in the frame.
sucked.
