    N/A IDI Turbo Conversion

    If your pulling heads off, it’s common to cut off 5 thousandths from the head surface, making sure they are within specs. Decking block is mostly done when entire engine is being rebuilt. Not necessary when putting new HG’s on

    N/A IDI Turbo Conversion

    It depends on your ability & if you have a cherry picker. I had both heads off (in frame) in about 2.5 hours. Had them back on & engine running in 4hrs. That was second time doing it in frame so it was easy for me. An engine hoist is a must. It really comes down to how far you want to go with...

    N/A IDI Turbo Conversion

    Every 6.9 & 7.3 that I have seen that has not been opened up has had weeping headgaskets. That is the #1 problem with these engines imo. Blowing headgaskets. When I bought my truck, headgaskets seeped coolant & oil for years before I put new gaskets on during turbo installation. Long story...

    extra cooling.

    That’s pretty slick. Looks like clutch is electronically activated. Far better than an actual electric fan and probably a hell of a lot better than what our rigs have stock. Most semi rigs have something similar

    extra cooling.

    Hmm, well I bet a 4 row champion would be even better in your application. Wouldnt go with an electrical fan. They are junk and don’t move enough air for these beasts. I would say one of the best things that can be done for a 7.3 is removing those rear corner freeze plugs in cylinder heads...

    extra cooling.

    Anything below 240 is acceptable when going uphill or towing for these engines. Got original fan clutch in it?

    N/A IDI Turbo Conversion

    If you are referring to head studs, this may be true with a 7.3 idi, not a 6.9. Your on borrowed time when you turbo a 6.9 without headstuds. At the very least, headgaskets and bolts should be replaced if your not going to use studs when you turbo engine. One of the weakest links with these...

    How to clean a rusty axle

    Holy smokes that’s some rust there. I’ve never seen a shock that looked like that. Man I bet you need a torch to get those bolts loose

    How thick is the exhaust manifold ?/Pyro probe Q

    Dab some grease on the end of drill bits. It’ll help catch the metal shavings from falling into the exhaust system while drilling. If your running N/A, I wouldn’t even worry about it. The exhaust will blow all the shavings out the tailpipe.

    N/A IDI Turbo Conversion

    You heard wrong. That’s all a bunch of made up junk whoever you heard that from. You can turbo an N/A engine without any problems. However, it is strongly advised that you replace headbolts (preferably ARP) & headgaskets when making the swap. These engines Achilles heel was definitely the...

    egt and water temp seems too low

    Nope I wouldn’t touch those bolts. Probably better off to leave them as is.

    egt and water temp seems too low

    You overtorqued those headbolts. If ARP says 80ft lbs, that’s what it should be. Wrenching them down only ruins the bolts, doesn’t benefit head gasket clamping force either. They would know since they kinda engineered them.

    New to me 94 IDIT rescue.

    AEM is one of the best from what I've heard. Had one on my idi when it was turboed. My Jeep came with a K&N cold air intake and I want to eventually put an AEM dryflow on it. Not a big fan of K&N filters because they don't filter well unless you have a sock on it.

    It will be quicker off the line than if you had 3:55's. Cool build!

    New to me 94 IDIT rescue.

    Spectre brand air filters are junk. A member on here ran one for a while until he discovered piles of dust in his intake system. Change it with something like an AEM dryflow filter

    New truck need help 1994 7.3 IDI Factory Turbo

    Nope. At this point, if it runs good & isn't making any unusual noises, forget about it and run er.

    New truck need help 1994 7.3 IDI Factory Turbo

    If your engine is turboed it also went thru that. Probably boogered up the hot side wheel. I bought a turbo a few years back with a gp tip that had passed thru it. Ugly lookin stuff when that happens. Could have been prevented if the PO spent another $2 on motorcraft glowplugs. Sometimes it's...

    Engine Preluber

    I think a freshly rebuilt or new engine should be oil primed before it's first initial start. After that, engine oil will leave a thin film behind, offering protection until oil pump catches up. And after an engine breaks in, metal parts have worn together which means friction is drastically...

    Return line rail

    I've always used return line kits from Russ. Hell, I've even reused the caps & changed out the viton o-rings and never had a leak. Good quality kits won't leak & should last at least a decade

    I'm new so please don't yell at me!

    Buy a set of D code stanadyne injectors from Russ aka typ4. They are way better than any autoparts injectors, and even better than delphis. I've had them all and can tell you stanadynes are the best.

    how to time

    Very simple answer. You don't time it without any timing tools. Just like you don't change your oil if you dont have any motor oil
