too show how bad ssds is it cost me 5k to rebuild my motor after a marine injector tip blew off. thanx ssds. and as a way too go give dave kennedy a call. Im not saying hes better than Heath but he is cheaper and his parts are lasting.kennedydiesel.com but you cant go wrong with Heath diesel. they have the right parts for your 6.5 and they know what they're doing. and there chip gave me 75 more HP I was blown away. but anydody besides ssds is great.

Okay, you used the words "free" and "horse power" in the same sentence. Those are two diametrically opposed terms

I'll assume you turned the pump up when you installed (or somebody did) the Banks. After that, nothings free. The Banks exhaust is about as good as your going to get and your not going to put more than 10 psi through the turbo.

Now, if you want to spend some cash you could mount a Holcet turbo on the Banks manifold. Its a custom job and not easy but you can get 35+psi. Of course, if you do that you need head studs and crank girdles. Fact of the matter is your never going to get more than about 330HP out these 80's technology engines (and that is with a fair bit of work!)

Most folks are happy with the Banks Turbo kit. Decent power, reliable, easy to install. If you want too much more than you have, your going to have to move up the technological ladder to a Cummins, Dmax, etc.

Good luck!!

there is a company called diesel depot that built a motor for a guy named bill heath who owns a very good 6.5 diesel aftermarket company who runs at the bonneville salt flats doing high speed runs. he is also turning 5,000 rpms so they know they make a good motor.
here is the link. i hear there not great with answering the phone so be patient and maybe e-mail them and call them a few times.

Free mods would be to remove the snorkel out of the fender if it is still in there, that's a big one. Also, open the entry point into the airbox a bit.

If you want to go huge, just ask!

a nice add to the system is propane injection - it lower egt's,increases mpg 1 to 3 mpgs
& you can run it when you need it - run full time it uses 1 gal propane to 10 gal of
diesel roughly
