2000 sd 7.3 build up tips

Bluemule · Dec 6, 2014

I've got my hands on a 2000 sd motor with 30,000km on it from a wrecked truck. I plan on dropping it into my obs which at the moment has a hurt motor. The mods I already have on the bad motor that I plan on swapping are. T4 s468, 300/200 ff, studs,pushrods,beehive springs, complete fuel system, stealth pump [got gen 3 on standbye maybe] and idm plenums. I was just wondering if you guys have any tips for me before I get started on prepping the motor, since I plan on this being the last motor I put in the truck hahahaha.

Thanks,

Maybe a fluidampner.

I was thinking about that. They just help the motor with vibrations?

You'll have to use the manifolds off the OBS engine for the install. I'm perty sure the passenger side SD manifold is diffrent.
Also I second the fluid damper&#55357;&#56397;.
Check , make sure the SD engine has fordged rods. It's a toss up. Prob does.

What's "hurt" on the old OBS motor?

Bad compression

I bet it's bottom end related seeing as he had 300/200's and a 468 on it. That combo has been hell on motors, it seems like.

OP, who's tuning are you using?

Forgot to hit send before the OP posted about compression. :morons:

Matt is one of the best tuners at keeping higher HP builds in good shape. I love his tuning. Was it live tuned? How many miles on the original motor after the big mods?

Bluemule · Dec 6, 2014

Wasn't live tuned, I wish. Supposedly around 100,000 miles

How's the "new" SD motor on compression?

OBS-Addiction97 · Dec 7, 2014

So 100k on the original motor? That's a short life, even with the mods you have.

Bluemule · Dec 7, 2014

Not sure on the new motors compression just yet, I'll be checking that on Monday when I get going on it. When the truck was bought from the previous owner it " supposedly" had a reman motor with roughly 90,000miles. So on that note who really knows how many actual miles where on it.

If you really want it to be the last motor you put in you wI'll be building the bottom end....

Should I pick up a f250 or 350?? I'm leaning towards the 250 any ideas on what to look at??

Take your old engine out, scatter it on the bench, put a $1600 rebuild kit in it with MAHLE pistons, have a GOOOOODDDD machine shop machine it and check everything, forged rods are tougher than you think. Deck the block, put some new cam bearings, bore it, freeze plugs, and a good hot tanking will be your best bet, to be honest you have the ARPs already, and all the other goodies, have the heads checked out too, put some injector cups in and clean up and lap the valves in.. THIS way you KNOW what you have... Then BALANCE IT for abuse and then add the fluiddampner...

If you want to drop some coin, call swamps for a set of heads and a cam

Unless you plan on towing A LOT, I'd do an F250. Why pay the extra $$ on those two extra wheels, plus the fuel you'll use with the lower gearing?

I'd invest in a good scan tool and use it during your test drive. That will help you identify any weaknesses in the truck you might buy.

Balanced and blue printed is the way to go on the bottom end.

If you're going to drop some coin, get Swamp's built long block.

Holy smokes that seems like a lot of work haha. It's probably the best bet tho if I want to do it right. Only problem with that is I've never done work so extensively before. And finding a good machinist that knows what there doing would be a bit tricky.
