e30 M60B40 5-speed!!

[artoo93]

This build will be finished come hell or high water as I need my car fixed!! As much as I love riding the Harley, some days I just want to sit in a car and drive without worrying as much of some idiot pulling out in front of me. Also the days when it hits 95 with 90% humidity can make wearing my riding gear completely unbearable!!! Hopefully make more progress with the long weekend.

Subscribed because i like pictures and regular updates. Hopefully this build doesnt fall through

[artoo93]

We got the m6x swap kit when you are ready!

Already got the motor mounts and pedal mounts from you! Just about got everything cleaned up so I can get the pedal mount installed. Just trying to clean up the bird nest of wires in that area!!

Jean - Plan on one after I finish the rebuild and also I want to do one at the break-in oil change and at the first regular oil change so I can compare numbers and share my findings with the group. I didn't get to do a real good check before I broke down he motor but I did do a hand crank one and all the numbers were real close to each other. I had one cylinder that seemed low but I used compressed air to check and it held 75psi with less than a 5% drop over a 24 hour period so I called it good. Of course now that will be a moot point as I tore it all apart but we'll see what I get when I'm through. I'll update more as I progress on this.

artoo93, do a compression/leak down after it's put together, very curious how it ends up working.

JGood - with 4.4 you probably won't even have to touch the bottom end, other than rod bearings.

I will find the info I have on the AN-30 compound and let you know. There is a lot of information out there for rebuilding Alusil engines but mostly dealing with Porsche engines. Pretty much the same block material and there have been a couple of guys that have done what I am doing. I will update as I do more.

[JGood]

Interesting stuff! I don't know anything about this type of work, but I'm anxious to see how it works out for you. Sounds like it's not that big of a deal to clean up these cylinder walls after all. Maybe I'll give it a shot if I ever get around to doing a 4.4 bottom end.

Any additional info, tips, etc... you have would be appreciated!

[Vtec?lol]

Looks good. does that compound you're using bring silicon to the surface? I'd be worried about a good seal or the rings digging into the aluminum.

Well I finally got a chance to do a little work on my block tonight. Only had about 30 minutes between other tasks!!! Here is what the cylinders looked like before doing anything to them:



After:



This was just the first step. I used a regular triple stone hone with very fine steel wool wrapped around the stones and a red scotch-brite pad wrapped around that. Ran this combination in my 1/2 inch hand drill with just a little bit of WD-40. I will do the other 4 cylinders hopefully sometime this week. I will clean all the cylinder walls and then use the AN-30 Silicon compound to finish them up! For that I will be using felt wrapped around the same honing stones. So far so good!! Now I just need to get the rest of my engine parts to include new rings! I have gotten some of work done on the car itself as well. Got the core support out and the new one arrived so now it is time to work on that as well. Dash is out and getting rid of every extra wire that is not needed aka ABS!!! I also spent some time sorting our the wires under the hood and split the harness in two to route the wires down both sides of the engine bay to make the removable core support easier to deal with. No wire harness running across the front to hang up on!! Hopefully either this weekend or next I want to get the Garagistic pedal mount installed with my pedals and master cylinders!!! I'll post more as I show more progress!!!

[artoo93]

I will be using AN-30 Silicon compound to clean up the cylinders. I had looked at getting sleeves for the block but that is just out of my budget! I've been doing a lot of research/reading and have a good friend that has done a lot of this work so that is a blessing. "Hone" with a green Scotch brite coated pads and then final coating with the AN-30 and felt hone pads. We'll see how it goes!! I'll be well documenting this part especially.

You can't re-hone them like you would normally with an m10/m20/m30/m50 etc...

right, using the acid etch is what makes it a different sort of job.

I was under the impression you couldn't hone Those cylinder walls

you can, you need to do an acid etch first though.

You may be talking about boring though, which is a bit tight, as there isn't much room between cylinders.
