[85 Sunrader 4x4 Diesel Project]

I'll be using a Toyota 5-speed, probably an R-151 turbo tranny that I have in a parts truck here. They have a nice low first gear that will be perfect for the Sunrader. Mercedes seem to go for a premium out here on the west coast, very occasionally I see them that cheap though.

I'm curious of transmission temperatures and coolers in sunraders. Also whats the ratios of that R-151 tranny?

If I have stock nissan automatic, what temperatures should I be expecting? And how can I cool it if I wanted to? Aftermarket kit for that?

Your going to replace one of the most dependable v6's out there with 140 hp with a diesel that puts out like 63 hp. I don't get your reasoning

What year is your Nissan Sunrader and how long have you owned it. I try to keep track of them since so few were made with the v6

Yah, not happy with the options. And really the SD22 was probably never going to happen for me because of the hp. Thats why I'm curious about the Mercedes engine. Since there is not much room in there it's hard to come up with a good diesel replacement. Looking for better MPG.

I've owned it for about 3 years. 18ft. I'm curious about other nissan owners out there.

That looks great. And I'm currently looking into replacing nissan v6 gas engine in my sunrader with the SD22 nissan diesel engine. But now I'm curious about the 300d engine now. Which 300d engine are you planning to use?

Also interested in performance with a automatic transmission? Or should I also convert the sunrader over to a manual?

Cheers,

I'd like to find some way of repairing the floor that doesn't involve removing the shell and cab from the frame.

You'd be surprised how much room there is under the hood of a Mercedes converted toyota. It's a little tight front to back but there's plenty of room on either side. Here's my buddy's truck:
