I have a really nice 96 Suburban 2500 2wd with the 6.5 TD. I can't stand the price of Diesel and all the engine noise. I was thinking about selling off the 6.5 TD and swapping in a LSx. Would it be any harder or easier on a diesel truck? I have the 4L80E trans, will that work or should I just get the trans that comes with an LSx motor?
Thanks!
Sell off the whole truck and buy a NBS truck. You can do it but its going to be quite a chore. If you've got a lot of patience and deep pockets, it won't be too bad. Unless you drive a 50k a year you'll not do much better on fuel costs in the long run if you factor in the conversion costs.
Oh yeah, the TD has a different bellhousing shape on the transmission to engine mount if I remember correctly.

The problem is a NBS is well over $10k and I only paid $3500 for this one and it's near mint. Also I don't really like the look of the NBS suburban. I would most likely buy a wreck and just swap everything over. I'm just wondering if there is anything specific to the diesel that I need to watch out for...
It shouldn't be much different other than the fact that the diesel used a lift pump from the fuel tank to the injector pump, no intank fuel pump. The fuel pressure on the lift pump was only about 15 PSI. I can't remember if theres a return line to the fuel tank. The conversion is quite possible to be done. One nice item is that you already have the hydraboost power brake setup.

Maybe you could just convert it to fry oil.

Diesel prices aren't the major factor. I can't take the noise any more and the power is not that great. I think a nice LQ4 in there would be much more fun. If I could get 14-15mpg on the highway I would be happy.
I hear ya! I bet 15 would be the limit with a heavy vehicle and that 4L80E trans.Originally Posted by cj93z

With the noise that makes, why not just pull the carpet up and put down some dynamat or something to lower the volume. They make some you can stick on the firewall and under the hood, too.

Have you ever driven a diesel? I don't think the dynamat would help too much. When the windows are open around town is the worst....
1995 K2500 4X4 diesel. Yeah, I've owned one. I hate them money pits.
