cheap engine mods?
 

hey im poor and i got a 1990 Mazda Protege LX and i was wondering if you have any ideas for cheap mods for the engine

intake adapter and cone fitler rx7 vaf swap, muffler will help u can make ur self a cold air intake extension like this one http://www.mazdaracer.com/images/pro/VAF+CAI.jpg and then u can dress it up a bit

how much of a difference do you think the cold air intake would do?

18º total ignition advance. I got 8whp more on the dyno over the OEM 10º setting.

try engine dress up look it up man good luk
