I have a 99' chevy prizm LSI. Im currently under construction... so bear with me here... so far for the additions to my car... I have added a new Dual headunit.. 220 watts.. I have added 6"X 9"s into the back window where you could normally only fit rounds. I then recovered the back speaker boxes and covered the back window with material.I painted all of the doors black (interior)and did blue accents. Im looking for door inserts though for the electric windows and locks. if anybody knows... tell me. I painted all the cranks, and handles blue also. I put my front drivers side door through a plow last winter tho... so i need a new one.....
As for the engine.. i've kept it stock except for the new zoom clutch i put in, its runnin about 130 whp with a little matenance and some cleaning/working and its at a little over a ton... I recently swapped out my dash cluster for a corolla because i wanted a tachometer and a decent set-up. The install worked out to be around 20 minutes. but it was a pain without a tilt steering wheel. I also changed out my dash lights to blue and disconected my center council lights. I swapped out my clutch also. I flet it needed a new one, and when i took out the old one i founf it was scuffed badly and worn. I put in a stage 1 zoom clutch. The install took a few days and had trouble with the engine mounts. The clutch is real nice now. I grabs and im real fast off the line.
I jus got new seats covers from APC racing also... black with blue accents... its both front and rear seats.. with front headrests... i junked the back headrests and it looks a whole lot nicer now. I just got a new gear shifter and shift boot also. blue... following the theme of course along with some racing pedals. I jus gotta get around to some small matenance stuff including doin some of the painting for the seatbelts and other random things.
