      Pistons and rings are enroute. I've got a melling oil pump and pickup on order. Engine hoist and stand, mounts, seals, arp rod bolts, bearings and maybe a crank if mine isn't in spec. are what's left followed by the machine work tear down and rebuild. I'm going to see if I can borrow a hoist and stand before I buy. I'm anxious to get it done but I have to wait to see if I'm moving. If I am it's not going to happen until that's all said and done...maybe summer or fall :/

      Stock size yes, if my cylinders are out of spec I'll have to send them back to exchange for an over size and have the block bored. We'll see.. I'm really hoping I haven't run it long enough with the blow by and that the block has worn well over the years... Won't know until it's measured. I really just prefer to have the parts all on hand before tearing into the engine so it goes back together as quickly as possible.

      I did order the m328. It should make a huge difference with the oil cooler I'm running and the plumbing for that and the turbocharger and should help keep all the new top end parts better lubed than the stock ones ever were.

      It will be awesome to have the build done and turn the key for the first time.
      I'm almost at the point of admitting I've lost to myself and doing a full size drive train and SAS while I'm at it lol. But I really hope I don't this hobby is getting pretty expensive.

      Yeah I tried but the FedEx delivery manager system has been down. You could see the bike tracks in the sand all the way up to the door and back across the yard again

      Probably not even that. Jerk probably just has it sitting in a junk pile out behind his meth trailer

      Been dealing with the holidays and a back injury so still looking like summer before the rebuild will happen. I've got an overhead chain hoist that my buddy and I are going to mount up in his shop. So now it's just a matter of time.

      Hey guys, I'll be leaving Tatooine soon and the truck will be going into my buddies garage 1st week of April and the new heads are going to the shop for the machine work. It's a good shop so their busy and expect a 2 week turn around. But ill have the engine pulled and bottom end done by the time I get the heads back and by May I'll have it back in action. Going to improve up pipe and wastegate pipe design while I have it out to fix some clearance and flow issues as well as rebuild my snorkel intake to have removable fittings and improve reliability. Starting to get pretty excited again...
      one un related thing I'll Have to do while I have the time is brace the rear frame. My swing out carrier is bolted to one side and the end of the frame flexes in a twisting motion. It's not huge at the frame but at the end of the carrier it droops 6+ inches and that's without the tire or fuel cans. Im thinking of spanning the frame tails top and bottom with 1/8" flat bar and just welding them in.

      Also splurged for a roof top tent (RTT) so I'll be welding the cross beams for that together while im at it.

      I cut some c-channel steel that will ride over the factory mounting rail as the mounting base and used 1/4" hex bolts and T-nuts to secure to the rails.

      1 inch square tube will serve as a riser from the mounting plates to the 1inch square tube cross beam keeping it low pro on the roof and very strong. It only needs to support 150lbs but i feel much better having it stronger to take all of the dynamic forces the RTT will add duringfreeway driving and trail use. Once it's all welded together some rubber plugs will goon the ends. The overhang is so I can add additional beams in the future for additional rack carrying capacity.

      Then I will have to figure out some sort of method to lock it all down as RTT theft is on the rise due to the rising popularity and pricing making a market for used ones.

      I'll throw some pictures up for those who like pictures and will be documenting the engine build in April as time permits.

      [​IMG]
      Base mounts bolted to the rail marked for welding.

      [​IMG]
      Mock up of the rack. The rear OEM cross bar will go away. The tent will fit snug between the lights and the lift gate when open.

      Future plans for onboard air and a pressurized water system with microbial filtration in the works.

      I will be looking forward to engine building pics too.

      Well after reading this novel of a post for the last 9 hours while at work (12hour shift) I'm just in awe. I love the build man. Crazy you started this 2 years ago. I want to built a turbo setup for my 98 second gen that is also red and a 4x4. Probably use this thread as a reference for just about everything. I also have 3 other first gens as well. A stock 93 5 speed and a lifted 10" SAS 94 5 speed on 35s soon to be 37-38s. Plan on also building a high compression performance NA motor for my lifted one. NA=extra long term reliability lol. I also just started a on board air setup and a 10gallon stainless steel pressurized water tank (for long trips drinking water). I'll be following along and hope to have my own build threads soon. I'm from Oregon, been following EF for a while but haven't posted much till now since rick got on my case.... lol. What state are you in? I really wanna see your explorer lol. Hope you bonk a tweaked over the head with the new crankshaft!

      Glad the info will be of help to you that was the whole reason started documenting.
      I'll be back in Wa within the month.

      Some things I'm changing besides the high performance engine build is my wastegate location. I need to make sure it's not contacting anything as the pipe got stress fractures from vibrating/smacking into under high torque the d35 axle tube. Turbo doesn't work so well with a leaky
      feed pipe.

      An aftermarket front bumper will probably be in the future to move the winch forward and allow a larger intercooler if needed. The desert in so cal showed me that heatsoak with the intercooler was my biggest enemy even at 8 lb, performance would severely suffer in the heat. But, the electric fan running all the time as a draw through was a huge help.

      If there was something I could do different it would be scrapping the a.c. system (keeping pump for onboard air) and having a custom turbo manifold made to place the turbo a little higher from the shock and frame.

      Food for thought to improve off of what myself and others have done. Sounds like you've got a lot of project ahead of you. And done right, which I think I'm finally getting around to, as well as keeping boost and tunes conservative, should be just as reliable of an engine as the next 4.0l... always hoping heads don't crack...

      @jd4242 hey, do you remember the spring rate that milling to a height of 1.6 gives you? My machinist is starting you work out a plan for the heads this afternoon.

      The 988 springs have the rate on them and install height specs..summit or comp has the specs..

      232 lbs open pressure
      Install height 1.6
      Open height 1.1
      Seat pressure @ 1.6 install height 117 lbs

      Thank you very much. He doesn't have the box yet as another shop is bringing the parts to him.

      No problem. .the spring seat and the valve seal nipple/pedestal dont need much milled but both need a little removed..make sure they do the seal nipple pedestal also though,the retainer will hit the seal and smoosh it if not..

      Got a lot of wrench turning done. Won't hear my the machinist until next week.

      The engine is out and torn down. I'm working on the lifters tonight and already replaced the rocker arms with the new melling ones. I'll be digging into the bottom end tomorrow after I get the timing cover off....turns out the head gasket (cheap cardboard junk) blew into one of the oil jackets and was pressurizing the crank that way. It's pretty clear that whoever I paid to do the heads 3 years ago took some shortcuts with some of the other things I am finding like water and oil jackets sealed closed with silicon sealant...major progress over the last week and a half though and the project will go on ice another month until I get the heads back and can put everything back together in June.

      Are you talking about some sealed off on the gasket or heads??
      Tried to look back but couldnt find it,your new gaskets are the blue felpro super duty right?have you already got the arp head bolts?

      So they were sealed off in the gasket with sealant but also had to pull sealant out if the jacket. Looked intentional though.

      I did get the felpro superduty ones and the ARP Studs.
