god damn, its about time josh :)

Crank scraper a good idea if you are going to track it. Prob not a bad idea even if you do the parking lot cone chasing.

Oil starved bearings do bad things. Ask me how I know . . . .

YES! Please make this a required item. I have the same setup youre building if youve got any ?s. And I'm still planning on going S52...fwiw.

Check out this place for a crank scraper. They seem to know what they are doing:

What do you plan to do for software?

Maybe it's just me, but I think you are going to put a good amount of money in to this thing, and be disappointed with the result. The cost vs. power-gain ratio will be high if you do a proper rebuild.

He probably meant crank.

So the knife edge would be a waste, eh? Good to know, I don't want to spend money where it isn't needed. Should I still do the crank scraper?

Yes I did.

Woot for leaving work early to get wasted on Cinco de Mayo.

Thank you for being redundant.

[AndrewBird]

lol. I didn't even notice the place you posted was the same place I was talking about.

Oh well, at least now he doesn't have to google it. :)

I am probably going to do a MarkD chip. Not following what you mean by "proper" rebuild. What's wrong with how I'm planning to do it?

what was mounted there on the driver's side of the block above the oil pump drive shaft? I've never seen studs in that location on an m20 block

Its not that your doing it wrong. I think hes just saying with the build your planning, your going to spend a lot of money and not get much hp gain.

Alternator bracket maybe? I was trying to figure out the same thing when I first looked at the pics.

thats the studs to mount the cold start valve for the OLDSKOOL distributor cars--e21/non kat 320 e30s and such.

I'm going to get the engine I want, with the mods I want. I can change more things later, but initially, I'll have a fresh, really quick M20. I think I'll get pretty good power out of it. I'm really not going to have to spend all that much on parts. Mainly what I need for the engine itself is headers, an i head, seta pistons, and an i harness/ECU. Then I just need a more appropriate diff, and I'm going to have a full exhaust done.

So Mike, if I'm not going to be using the hella old cold start valve, can I just hack those studs off? I was looking at a couple other blocks I have sitting out back, and neither of them have those studs.

Talk to some of the LOCAL engine builders. See what they recommend as far as machine work goes. Honestly, I would build a "loose" engine and make as much power as possible via a custom tune/stand alone.
