What are some cheap engine mods that i can do to get more hp and a lot of smoke for a 12v?

 

Put a bag over your air filter, or cut an intercooler boot. Lots of smoke for little money.

 

Manual or auto? Stock clutch or trans can't handle too much power. Here's a link to get you started https://www.dieseltruckresource.com/...3.html?t=78573, but remember anything stock behind the engine won't last.

 

Lots of smoke means unburned fuel and wasted money, so your post is confusing. Why do you want cheap engine mods if you have money to waste?

 

Smoke seems to be a status symbol in some circles.
Guy at another CTD website asked how to get more smoke and someone told him to turn his airfliter upside down.
The guy actually tried it and reported back that he didn't get any more smoke.
