also and good tricks on getting bit more power out of it i dont mean major work stuff like port n polish or cams just little bits for now i know on my old polo gt there where loads of bit you could remove / blank off smooth out to get some small gains any ideas welcome
and drill the air box dont work  as i found when it wont run lol |
Not worth removing the rev limiter unles you change the cams etc as the later 5 cylinders in the series 3 cars ran out of puff after about 5700rpm anyway. well worth removing the CAT on the exhaust, perfectly legal on an 89 car. ALso as stated, decent fuel, decent plugs and leads decent filter and taking a chunk out of the bottom of the airbox should not make any difference to running/ starting unless you pulled something off in the process. Chopped the bottom of mine and added a stainless chute to guide cool air in. Good luck
