Title: Lsx for jet application
Post by: jayare92 on January 29, 2015, 05:04:28 PM
Has anyone used an lsx in a jet application? Ive heard of alot of people talking about it. But since these motors have been out for some time now im surprised we dont see more in boats. they put them in everything else. Haha

We put an LS3 in a Rogers.  It hauls the mail.  I think it's a pretty trick little setup.  Nice and light.  Pretty robust.  Good power.

I've been wanting to do one for quite awhile...

A little L33 with a turbo (or 2) would be awesome!

Flusher, what kind of headers are those?

That is awesome! What all did u need to make that motor work? Im assuming they dont sell very many parts to put those into a jet boat. Id love to do something like that in the future. What was the overall cost on a project like that? Way lighter motor, parts everywhere for those also!

They make everything you'd need that's jetboat related. LS pto, headers, and railkits are all available.

A carb manifold and an ignition controller and your pretty much there.

Might have to fab some water inlets.

I made the rail kit and PTO.  Water inlets/outlets are 3/8-18NPT tapped into the front engine plates.  The MSD was literally plug and play.  I heard that the crate engine that ended up in it was ~$9K and about 100 horsepower more than that which was featured in the Roadkill episode being filmed at the TPM.
