So, i like to think of myself as a pretty mechanically inclined guy so i want to try my hand at doin engine mods.
in the past, on my street cars ive always done porting and polishing on intake and heads, so im sure ntro engines would be a breeze.

my question to you guys is, do you know where i could find any info on learning to mod nitro engines. ive got a few engines lying aroud that im pretty much gonna throw away anyway, so they are gonna be practice engines.
im not interested in takin my engines to anyone that does mods, i want to learn it myself.

thanks for the help
