i have a 2.3. with not even a cone filter! lol. so i have no reason too. lol. its all suspension work.
for going fast, i have my 626gt touring, with a JDM fully built turbo FE-DOHC, on standalone, lsd, the whole shibang. also a turbo probe gt. those are my two toy's for going fast in a line, 6 is for corners, and just looking good. then i have a beater 92 ford explorer, and a 89 probe lx. and of course a turbo dodge colt GTS hatchback. but thats so far from being done, its really not even worth mentioning yet. lol
