    Rebuild my own engine?

    I'm going to rebuild my own engine. I'm not scared to make that statement here, because these forums are all about doing it ourselves, right?

    I'm confident I can do this, I've actually rebuilt an engine before (and it still ran after!). I grew up around my dad re-building things, worked in construction, and am quite handy.

    Are there any good resources out there for this? Shopping lists? I have a general idea of where I'll need to start. Some idea of the things I have to send out (machining), etc. I need to build a solid shopping list and balance what I want with what I can afford.

    I did it myself. Currently finishing up the first car motor ever.. Shop list? I would just make your own. Make sure you get a forged crank in there if your putting any power into it . Id do all the stuff associated with 120k maintenance just because. Oil pump, water pump, timing belt, tensioner and pulleys. Check clearances according the the rebuild manual.

    Very helpful:

    I only bored the block, decked the block, polished the crank, and balanced the assembly. I did go with aftermarket rods and pistons. I didnt touch my heads because I couldnt really afford it time or money wise.. But I would have pulled them all apart and replaced valve stem seals at least and had the heads decked so they are flat..(Waiting till I can afford 727 cams )

    Lots of knowledgeable people on here should be able to help you out more than I can.

    I definitely want to do forged crank, pistons, etc. I do want to make as much power as possible, within my budget. As for budget... it's more a money over time equation than anything. I can go crazy with this the more time I'm willing to drag it out. My monthly income is comfortable, but have some domestic issues being resolved right now Which also means I have all kinds of time LOL.

    I would pull the engine in there now, and rebuild that, but I need to be driving it. I figure I can find a good block, then start from there. Get the pistons and crank, etc, bring it to a local guy here for the machining. Then start building the other things. I've seen some great deals on "lightly used" pistons from different forum posts, so I'll probably go that route vs. buying new. Why not if I can save a lot of money?

    So, to start:
    block
    pistons/rods and all parts associated (bearings, caps, bolts, etc) (stroker????)
    forged crank, all the seals to go with it
    send all that for any machining, cleaning.

    Then start on the heads, valves, etc. Once the engine is together, start getting the accessories. Water pump, radiator, shiny pretty hoses, shiny valve cover, etc.

    oh, and then the fun stuff like new turbos

    A pair of 19T's wouldn't hurt any. Then you would need to get minimum 550 injectors that would no doubt require a fuel pump upgrade and a hot wire kit. See how easily it can get out of control when one thing leads to another.

    Ask me how I know that.

    The most important thing is to take your time and do it right which it sounds like you will do. Find a good shop with references to do your block, balancing, ect. Use OEM parts and follow all specs and you should be fine.

    Great suggestion for the OEM stuff, thanks! Those are the things I don't know that I'm looking for advice about. Not to insult the young and responsible folks, but sometimes age does have it's advantages. I have a lot more patience and will happily wait an extra month if I need to get something done right or spend a little more money.

    The turbos on my car are pretty much shot, I believe. So a turbo upgrade is in order, but I don't want to go overboard initially. I'll be spending a lot of money on the engine itself, so some things will have to just wait. I just need to find a good middle ground there. I'm really not sure how much I'll be able to salvage off my current engine. It runs, but I just have this feeling of impending doom like it's ready to just die any minute. It's old, and wasn't well taken care of.

    There's only one shop in N. Texas that I would trust and I have to drive a long way to get there. There is a big difference between our engines and a small block chevy. We have very tight tolerances. I would definitely get referrals for a proven shop.

    Most powerful 13T car in the world @501awhp, PTE 780CC injectors, AFPR, E85, Greddy Profec B, 3.5" Granatelli MAF, MAFT, SS Headers and O2 housings front, 3SX downpipe, CRX racing FMIC, Dejon intake pipes, Ground Controls, Maximal adjustable rear control arms, Maximal TC Brace, Poly front and rear mounts, Vacuum Reduction, EGR block off plate, Hot Wired Walbro 255 and inline Walbro 255, Southbend stage 3 clutch, Slotted and vented rotors, SAFCII, Turbo XS BOV, 3SX FP hotwire, Seatle Short Shifter, Jackhammer timing gears: Best 1/4 mile 12.33 at 114.9 mph 1.79 60ft.

    Plus a lot of shops dont have the tools to balance the small V6 cranks. Also you need to make sure they have a way to machine our 2-Step flywheels.

    We have a few Mitsu "specialists" in our area. Atlantic Motorsports, UCS Performance (though I know Greg can't do the machining, he knows people who can) and Auto Velocity. I'll definitely make sure to have them all recommend someone to do the work, and see if there is a consensus on who is best around here. I wouldn't have known that "just any machine shop" couldn't do this.. thanks guys! I'll see if I can document my entire process and write a few DIY's on each step.
