My engines break really fast for example viper with mihon's venom engine kit is so much broken that after 1 minute ride on a test track i have to pay over 4000$ for fixing it...and no i do not put any crazy rpm or nitrous on it just normal ride...so what may be the reason? Does it change anything that the engine doesnt fit the chasis 100% perfecty and i had to change its position a bit (bit it doesnt touch the ground anywhere)?
Probably, durability is set too low for certain parts. You can change it in the javas, but i don't know if mihon released them.
