Rear mount turbo or 5 ton with nhc 250

[Pandawelding]

I have read around on the forum and have found plenty of info on turboing the 5 tons with the nhc 250 engine but i have not found any info or anything on anyone else trying to rear mount a turbo behind the cab. I have seen a lot of comments about reworking a bunch of stuff under the hood or having to build a bubble for the hood to clear but it looks to me like a decent alternative would be right behind the cab. I have a 939 wrecker that we replaced the crane with a cargo bed on and there is a nice gap between the bed and the cab and there is wide open access to the exhaust and intake plumbing.looks like it could be done with minimal plumbing fabrication and a few oil lines to me. I know that it wont be as efficient back there and i probably wont be able to run an intercooler but all im looking for is a little extra power for going up hills with a load and that sort of thing. Anyone tried this or know of anyone who has. Anyone have any input on this idea.

Alot of fab work for not much to gain. On a 809 series where the engine bay is small and full of stuff is one thing.

I have an aftercooler and turbo for sale in the classifieds. I also have a radiator/oil cooler/intercooler setup that fits the 939s with minimal modification.

As far as the turbo on a 939 it is easy to do it all under the hood due to the hood height being reasonable. The cross tube clears just fine as well. It would be extra work with no reason for it.
