u could do a 62/65.. they have sales on them all the time, round 1k

 

I have ran one of thoes and I really liked it a lot. spooled very quick and had tons of low end grunt, but I ended up getting rid of it because on the top end ( round 2800) it would choke. I pulled many trailers with that charger and loved it, def a good choice.

If you can live with a little more lag the 71 wheel will offer your more room to grow. I have never ran propane so I do not know how the truck will react.

If you do wanna get a new charger the 62/68 would work great for you

 

62/65 is the size on the compressor and exaust housing?

 

the 62 is the inducer size of the compressor wheel and the 65 is the inducer of the exhaust wheel

 

so does the housing size affect it any way? and i forgot to mention about getting a set dvs

 

yes the housing effects how well the turbo will spool up and how well it will do in the upper rpm range. There are many choices out there, the most common on the s300 based chargers are 12 cm, 13ss, 14 cm, and 16ss.

For what you want I would go either the 14cm or the 13ss if you have the money for the 13ss.

 

what is a 13ss?

 

13 cm housing made of stainless steel insted of a cast housing

 

expensive.. thats what it is

 

works very well tho
