Building a 2.7 - Budget?

[zipdoa]

Wondering if anyone has a comprehensive (EXCEL!) list of what was purchased/replaced/labour etc for building a block, I'd love to see some examples.

I'm doing a stock block K04 setup this summer, but in the meantime I'm sourcing an '05 BEL and will take my time building it over the next year. Probably go 770 or similar on E85.

Share the knowledge! Motor removal and disassembly/non-critical assembly will all be done at home.

Budget build list:
H-Beam Forged Rods
Rod Bearings
piston rings/cylinder hone (optional if original rings/bores are in good shape)
don't touch the oil pump, main caps/crank/main bearings/main bolts
ARP Head Studs (optional)
Head Gaskets
Exhaust/intake manifold gaskets
Any other maintenance items you feel like refreshing (TB/water pump, top-end gaskets/seals, etc)
This is about $2k in parts to do it right. Or about $800 if you cheap out and go bare bones.
Labor prices vary a lot, I would suggest finding a local shop and talking to them.

I've got a pile of videos on Youtube covering my recent build. Not sure if you'll find it helpful but I have a few DIY's in there too:

Budget wise.. it'll really depends on your requirements for performance, longevity, reliability, and how much attention you want to pay to "while you're in there" stuff and non-functional enhancements (paint/powdercoat for parts, carbon engine covers, bling!).

Are you looking for a budget for the stock-block K04? Or the BEL? Even a simple K04 build can add up quick (ask me how I know lol). There are a million o-rings / gaskets / seals / fasteners that add up. I should have my order invoices from the build if that will help you? Sorry it's not in a spreadsheet! I should have a spreadsheet for the big stuff, somewhat not relevant to your BEL build, though.

Order invoices are helpful - just to skim over and build a list for myself.

I have a well sorted 01.5 S4 avant that I'm manual swapping this summer. I'll be doing an B7 0A3 swap and OEM+ upgrades on the motor while it's out (K04's, Intercoolers, entire RS4 intake setup up to the heads).

Through this coming winter, I'd like to build an 05 BEL block for big turbos, so I'll be starting from the ground up. I imagine every seal/gasket etc will get replaced, and all the goodies will be powdercoated.

MAINLY what I'm interested in is the cost of all the non-big ticket items (basically every nut, bolt, gasket, washer, seal, etc) that are required to do a really good job of a rebuild. Not too concerned about rods/turbos/pistons etc.

Check out this post by DolphinV8. It's EXTREMELY helpful.

BEL and BF APB are the same blocks fyi. Minus the crank lock pin plug. But I'm assuming your only concern is the main webbing, which is the same between the 2. It's the early AE APB blocks that people tend to avoid when building the bottom ends.

a AE APB are good if you add a girdle to it to make it more "safe"

For the extra $100 bucks it costs to start with a BF block, it just makes more sense.

I actually have a sheet saved to plan my build, ill try to remember to post it when i get home.

It has a budgeting tool and timeline estimator built in.

Got bored lol

Bumping this - adding rods to my build. I'll be running K04's, and want to do the minimum possbile while keeping a 'good job' in mind, including balancing the rotating assembly. What is recommended while the crank is out? I was thinking rod bearings, ARP head bolts, ARP main bolts, not sure what else. I think stock pistons will be fine?

All of this is unnecessary for a k04 car. When you go bigger than that, then yes but it's debatable.

When you open the block, it immediately triples the cost.

Haven’t read the full thread. But you don’t need head bolts. Arp mains are a good idea because of cost/ availability

The only thing K04s need are a good running block, and damage free heads

I’ve had genuine ones on my car for the last ~100k miles now, and this summer will mark 5 years. Stock APB

The more you overthink it and the more misc crap you toss at it, the higher the chance that something goes wrong

Less is more… full engine rebuild with big turbos sounds good on paper but in practice it seems like 80% of builds end up parted out or abandoned. The ones that make it to the “well sorted” category tend to have a lot of money and time put into them. It will cost way more than you think and even if it doesn’t you’ll end up spending a lot more than you wanted to originally because of creep syndrome or while we’re in there itis.

It took about $50k ish to get mine fully built with TTE880’s, so pretty similar level to the 770’s you’re talking about. Of that, probably $6-7k was the block build alone with new 2.8 heads and valves. That also included full transmission swap, suspension, wheels, brakes, etc so not just the engine. I almost didn’t make it to the end because there were so many problems at one point… there’s a quote I think from CELison or someone else about a spider web of problems you should look up. If I didn’t have AMD Motorsports close-ish to me the build would never have seen the light of day because after a while both me and a good local shop were pretty stumped.

Spreadsheets are great but they have a way of going out the window mid build.
