Fantasy Diesel v drive Saltere or Pirata build

GM automatics have the same bolt pattern as a Velvet Drive?

Check out the Cummings 4bt! Its basically a 5.9 with the back two cylinders chopped off. 4btswaps.com! These guys love putting diesels in anything. I'm sure if someone started a companion thread they would jump right in on this topic.

Just a heads up, i will be dropping a 5.9 cummins from a dodge ram into a sunsport or a beast starting this fall, i am a marine engineer in the Canadian navy so i have a pretty solid understanding of how this stuff works, i will be using a p7100 pump cummins form a 1995 ram,with a upgraded 3200rpm gov spring (2600rpm stock) and maybe water/meth injection(depending on amount of smoke under load) will be using a custom air to water intercooler and a 1:1 72c velvet drive (same as the big block boats) as it is more stout than the 71c and should be able to handle the roughly 700ft lbs of torque, for a propeller i will be using a 14x20 acme as this should yield similar performance to the stock engine and prop. wakeboarding speed will be at 1800 rpm which is in the 6bt's sweet spot for torque and fuel economy. exhaust will be accomplished by bringing the down pipe from the turbo and splitting off to the two exhaust pipes with mixing pipes integrated into the y, unlike many marine diesels though i will be using a hot manifold and hot turbo, so they will be heat painted and kevlar wraped to prevent fire, the engine doghouse will be adequately forced ventilated at all times to also prevent fire. i will be using a full guage set including egt's, head temp, and turbo boost to keep eyes on all necesary information. as for how to bolt the trans to the engine? just get a sae#3 setup of flywheel, flywheel housing and starter, then a sae#3 to velvet drive adaptor to finish it off, still trying to find a damper plate that is cheaper than the 659$ vulkan torklfex but im sure there is one avail somewhere. the best thing is the fuel economy, at 100% load the cummins can only flow 44l/hour at 2000rpm, vs a 351 fords 150l/hour at top speed. Only reason the project hasn't started yet is because im leaving to go sailing for the summer on the coast. I will be making good copy;s of all my engineering diagrams i have created if anybody wants to take a look and maybe offer some added input, and if anybody does own a 86 sunsport i need some measurements.... height from hull to prop shaft coupling, width between two engine mount stringers and length of engine hole / length of prop coupling to front of engine housing.

So where is home??

The Cummins powered P pumps suck...... Only got 700 000km on mine !!!

[scotro95]

Ottawa, i see your from windsor... and 700km's... nothin to be ashamed of lol, better than a 6.0 power joke. or just about any of the v8 diesels.

Please make this happen & keep us updated. I love engine swaps...

Sold my old boat today to free up some capital to use on the project, already looking at boats but probably not going to jump on anything till i get back in September... stay tuned for a build thread once it gets started, my goal is to document it and make it simple enough for any motor head to do.
