Is the smeding diesel s300 swap for a duramax worth it?

[@janamaro5894]

Yeah, some people said "Smeding Diesel is a piece of junk, don't buy it from them it's made from another country!!" Well, it's made of materials for building turbos, manifolds, and components. Google rating Smeding Diesel 3.9 out of 5. It sucks, It happens to me, their shop, and the customer who bought Smeding's products.

I’ve had my kit for a few months and no problems with it people tf out of it

[@janamaro5894]

​@@Brandon__52502 exactly, I won't bashing everyone. Because, they are great products and good customer service.

I got 20k miles on mine, i didnt prefill it or break it in. Still goin

[@Brandon__52502]

Not bad at all

[@tristanwilson5957]

did the s300 swap on my 6liter same thing no instructions but pretty simple as long as ur not a rookie lol looks good tho

[@Brandon__52502]

Thank you. Yeah as long as you have a general idea of how these engine work doing this swap isn’t hard just a couple things that will confuse you. If they sent instructions with pictures i think a lot more people would buy the kits. That’s why i made a video of how to put it in.

[@masonmckiski3790]

When you put the turbo inlet back on did you use a different v band clamp or a bigger one I’m currently trying to figure that out my stock one don’t fit both turbo side seems to be bigger than stock

Who’s tunes do you have? I just put a 366 on mine and doesn’t nearly smoke as much as yours

[@Brandon__52502]

I have dans diesel on mine. But i also have a bigger turbo and a few fuel upgrades and a stock stall conveter so mine doesn’t spool fast on the brake and smokes to get up into the rpm’s. Truck spools fast as hell and smoke clears up past 2k rpm

I have motorops tuning with a smeding s366 in my lbz. 45 over injectors and piping kit. Little to no smoke. I miss rolling coal lol
