    Question D16 Rebuild

    Hi Guys,

    I'm looking at rebuilding the engine in my 98 EK1. Its a D16Y4 and its just done over 250000 km's i'm just looking for suggestions for what parts i should run in it. I'm looking to replace rods pistons, apparently i read somewhere (on here or turbod16.com) that this is the weakness in these motors. i want to build it to either turbo or even supercharge. But this wont be till later.

    So basically i'm planning on buying another D16 Motor and rebuilding it then doing the transplant. so i'm after ideas as to what go fast bits would be good for the rebuild.

    head to www.fjdistributors.com, they have a cheap turbo rebuild kit for $300US. comes with a set of coated negative dome pistons, all bearings, a metal head gasket, new water pump, and every gasket you'll ever need.

    the d16 rods are sturdy for NA, but not too sure about boost. fj distributors also have a set of I beam rods that are extremely durable, reasonably lightweight, and come with arp rod bolts (a $300 extra if purchased separately).

    they can also supply turbo kits.
    Current Performance Modifications to ED6:
    not telling, but it involves a semi-quad carb setup, and lots and lots of compression.

    > this is the weakness in these motors.

    Rods usually break at the 200Hp point.

    Oiling in the D16Y is not optimal for high Hp applications.

    Some simple solutions are:

    * porting the oil pump
    * shimming the oil pump relief valve.

    Better solutions include

    * installing a D16Z pump, (it's wider and hence more volume)
    * Morosso oil accumulator (My recommendation, not echoed by any1 else)

    There are pluses and minuses with all these solutions.

    > Semi desk block guard

    There's a lot of controversy regarding block guards. Do your research.
    IMHO they're not necessary/desirable.

    Basically its going to be an everyday driver, but i also want the power under foot when i want it.

    So i was thinking about going High compression although from what ive read this isn't desirable in turbo applications.

    Maybe plan B. Will build this motor tight and transplant it and rebuild the existing one to be better for the turbo application.

    I have a friend who has a set of Eagle H Beam rods and wants to know if i want to buy em. Are they good? he told me they are but this is the first rebuild of a honda motor, so i'm a little unsure.

    Piston brands? whats good and whats nasty?
    What should i avoid in this rebuild?

    Eagle H Beam rods are good stuff but you'll need to notch the block for those bad boys

    Match em with some Vitara - 75.5mm YCP Pistons plus ACL race bearing

    Then your starting to get somewhere, for boost that is

    I have read some good reports on the Nippon Pistion Sets. SeverAMV mentioned fjdistributors in his post above which resell em. Has anyone had any first hand experience with em?

    Will the H Beam Rods fit either set of pistons or is the pin a different size?

    If it was up to me, I'd say spend your money on a B-series conversion.
    But that's just my opinion.

    But, if you're going to turbo a D-series & you're serious about building something properly,
    Don't cut corners & don't use the cheapest parts you can find.
    Back engineer the whole thing from your final power target.
    Do it once & do it right.
    Most of the parts you'll need will be out of the US, so you can certainly shop around & get some good deals.

    And PM Weq,
    I don't know if he'll share his experiences with you,
    But if he does, you would do well to listen.
