    Josh – The factory will not sell just the engine block that is why they are so hard to find. A long block or a complete engine is all that you can get, we will however remove the new cylinder heads from a long block and sell it as a short block. Anyone you find selling only the engine block is not selling you an OE part!

    how much would you guys charge for just the block for this motor? very hard to find for a decent price

    With the correct internal engine components, turbo charger and increase in fuel delivery you can get about 300 horsepower out of the newer 6.5L diesels. This set up is great for the guy that does heavy towing with his vehicle, it is not a stop light to stop light race vehicle however.

    The aftercooler should add 10 to 12 hp especially in warm weather. It will also reduce engine temperatures 10 degrees.

    Do you have any experience with 6,5 td and adding a intercooler. would this do anything with the performance. i have a 1994 suburban, with 3,5″ exhaust,no catalysator, and marine injectors.
    Thinking of adding a performance chip(upgrading the ecm eprom) 40/80 hp.

    thanks

    Yes, we do offer a P400 with 18:1 compression and has new pistons and rings. It adds $800 to the price of the engine.
    Rods, pistons, and rings are a balanced set.

    Do ya’ll make a p400 with 18 to 1 compresion for trucks? I want to run my hx35 at 15 or so pounds of boost.

    Brock,

    Thanks for your question.

    I got some input on this from Matt this morning and this is what he said:

    If the truck has a standard ECM and injection pump it should be around 195-200 HP

    If the ECM and the pump have been calibrated the horsepower could be up to 250.

    It’s the ECM and the injection pump that determine the horsepower of the engine and not necessarily the turbo.

    i bought a 98 sierra 2500 with your P400 long block in it. just woundering what the flywheel horsepower and torque with a GM-8 turbo would be on your motor ? thanks

    The P400 is designed to be a vehicle engine. A vehicle engine is operated at varying throttle/rmp for city/highway use and a marine engine is operated mostly at a wide open throttle/rpm. The difference is in the pistons. The P400 has 21:1 pistons and higher compression than a marine engine which has 18:1 pistons. If you convert a P400 engine to a marine application you won’t get the horsepower you think you’ll have and you’ll have a problem keeping the engine running cool enough.

    If you have any further questions, call us at 616.530.1298 or send e-mail to Matt@PeninsularDiesel.com.

    Thanks for your comment.

    Looking for a diesel alternative to my small block powered 1980 Chevy 3/4 ton 4X4. I want good power and better economy.
