:-: pls HELP wid non-turbo 63 :-:

[t r e n t]

...i had a 4g63 non-turbo transplanted in place of a stock 1.3L CYCLONE engine. i probably wont be able to acquire a turbo kit for it, so i wanted to ask you guys for help. what would be the best and most effective mods or upgrades to get serious HP from an all motor 63. so far, ive only added an adjustable fuel pressure regulator and had the flywheel lightened... any info would be greatly appreciated, THANKS!
