2.8l stroker thread

[nando]

thought I'd detail the progress of my motor. I'm still waiting on pistons and i need to have the machine work done. I also picked up a ring compressor and a ring installer tool - pretty cheap, less than $25 for both.

the basic specs of my motor:
81mm 325e crank
86mm Metric Mechanic 10:1 pistons
S50 rods
2823cc / 172ci

I started tearing down my block today. the outside is pretty nasty but I was very happy with what I found inside:










I was amazed when I pulled off the head, 218k and the cylinder walls haven't even *started* to wear yet. the factory cross-hatches were perfect, and not even a trace of a ridge at the top of the bores. judging by the condition of the engine and the rest of the drivetrain (the T-case, diffs, and all driveshafts were immaculate), this car couldn't have been driven very hard. too bad the car itself was a total rust bucket..

the cyl. head was also in good shape, although there is definitely a coolant leak somewhere - the head bolts were wet when I pulled them out. Hopefully it was just the headgasket and not a cracked head or block (although I'm not going to use this head anyway).

still have to pull apart the bottom end, after that it's off to the machine shop to have it cleaned up, decked and bored.

Wow, the PO didn't break that car in too well. Thanks for the pics, i'll definately be watching this thread. Do you think you can include pricing info too? Also, what engine management route will you be using?

Ive been waiting all year for this.

[nando]

pistons just came, these things are beautiful!

the pistons are MM designed, but made by:


price for the motor right now is $3200. that includes new pistons, rods, bearings, machine work, oil pump, AFPR, ICV, oil pressure/temp gauges & senders, every gasket, and many new nuts/bolts, and more. still need to add rod bolts. I'll post a final price list later when I have all the parts here ready to go.

I'm going to break it in with the stock computer/chip, but later I'll go with an SMT7 piggyback, ditch the AFM and add a WB O2 sensor.

Detailed step-by-step motor build-up write-up please.

[NC325iC]

haha build up write up

sorry, im sleepy

[Sean]

With 221,000...my cylinders looked the same too, Nando! I was amazed! :O

You're makin me jealous with those pistons! lol Those things are daaman sexy!

Definately a messy block. Mine wasn't quite as messy. I'm too lazy to post everything I've done so far...soon though. ;)

Where'd you pick up the ring tools? Sears? I need to pick up a set too.

Can't wait to see the outcome! :)

What head will you be using?

[Jarvis]

So is that the motor from Fielding's car?

[nando]

got the tools at shucks, nothing special but they'll get the job done. I'm going to be using the head that's in my car, just rebuilt it last year.

yes it is! it's ugly looking but all the drivetrain peices were in great shape. and I still owe you money! need to send a check asap, but I keep getting sidetracked.

Ohh - you're rebuilding a different motor - that way yours won't be down.

Smart thinking man! ;)

[nando]

yeah, don't want to miss any of this seasons autox, I'm in the points lead right now :D

[e304me]

well have the block pressure tested and replace those freeze plugs

[nando]

of course! I wouldn't spend $1200 on forged pistons and then neglect $50 in parts/labor. ;)

Yea...then I'd have to go out there and throw my extra block at nando for being stupid.

Or try. lol

This will be done right - it'll probably be the hottest IX EVER! :D

Holy crap I had actually forgotten about that!

Sounds like the ix is gonna be sweet when you're done. Any specific hp/tq #s you're shooting for?
