Engine Rebuild Costs

[Rich]

Hi Chris, Rich again, in the time it took me to write my long response a few others popped up.  I have just spent many months of researching this same project and I am not sure how much spare time you have on your hands, but my strong recommendation would be to contact the writer above this, redshred, and buy his engine tonight, I must admit, it is very tempting for me to grab it, for the parts, time, energy and the end product you would be getting, it would be worth it, IMHO

I am just finishing up mine... I spent $500 getting the block bored, decked, and cleaned. Spent $300 decking the head and getting the valves ground, valve guides changed, etc. Another $300 for odds and ends from the machine shop, such as getting parts chemically cleaned and getting the crank+rods fixed up. I believe I spent around $1000-1100 at the machine shop. I then spent another $1000-1400 on parts... So well under $3000 for everything. All labor done myself, though... approximation... This is in the pacific northwest, where I would consider costs to be moderate.

...and those are good prices for machining.  What did you use for pistons?

I ended up having terry take care of it. I have not gotten it assembled again yet but the work looks great. Had him do the head and the lower end. I’m switching it to fuel injection and still have some other things to sort out on the car. Thanks for the suggestions and offers.

Got some used 10.5:1 pistons from someone here on the FAQ

If it's just machine work you're looking for, any competent engine shop should be able to handle it, you'll be on the hook for disassembly/reassembly though.

 

Here in Detroit, there's no shortage of domestic V8 engine builders.  BMW specialists?  Not so much.

 

I brought mine to a shop and gave them a printout of the BMW manual specs to go with all the parts.

 

Cost:  $860

Pressure Test Block + Head - $110

Degrease Block - $100

Bore+Hone - $150

Polish Crank - $50

Engine Balance - $250

Valve Job (including valve/spring installation) - $200

 

I spent ~$2500 for parts, including IE forged pistons and longer H-beam rods

 

I'm still assembling it, just slowly, too cold outside right now.
