Build Thread?
-
How far should I go with this motor re-build? Do I really need to do the main and crank bearings? or is that just extra money and time and work for something that really isn't a wear item anyway? Same question with piston rings, I would assume piston rings would be a decent idea, but is it really needed? I know I need to do a valve job and an MLS Gasket and ARP studs, because I am going to boost prep the motor while I am in there anyway, and if I can source s50 cams those would go in at the same time I think but who knows anymore. I picked up a laptop the other day after selling my desktop to TJ, so that was a good amount of money that could have been used in the swap, but you kind of need a computer to sell things efficiently, and realOEM does not work on my phone
All in all, progress is being made (kind of)

I guess, if I were in the same position (which I will be eventually as I rebuild the wrx motor), if you have the cash and the part isn't crazy expensive, i'd replace it.. The peace of mind + knowing you're hoping for big HP #s = I'd replace just about any moving part that you can.
-
Good price? It's almost another 600 dollars lol.
-
Odd, I had thought it was a ton more.
-
Soo....
-
Picked up those bad boys for my pops!

For what car? The porcshe?
-
Yeah.

Boost prep idea went out the window, especially when a headgasket and ARP studs are 450 without shipping, I just got an OEM head gasket and studs for 50 dollars..... so thats a thing. Getting the head rebuilt by a local guy, full valve job and deck. Did an awesome job on another m50tu. Motor parts have been ordered and motor disassembly will start... tomorrow?

So I pulled the head off of my e34 M50TU to get the head rebuilt (valve seals were not the best on the exhaust of cylinder 3). So I had planned on just rebuilding the head, and slapping it back on, that is until I saw the cylinder walls. I shall let this picture do the talking.
They are glass, not cool at all. The picture makes them look a tad bit scratched but they are not.
So I need to do something about that, and I feel as though I wont be able to re-hone those because they have a fairly good lip where the piston stops its travel so I can tell its fairly worn(fairly clear in the picture). I am thinking that I cannot get away with just re-honing and new rings, but am I wrong? Or do I have to bore over .25 and use new rings (which is freaking expensive) Anyone have any insight on this? Obviously I would like to keep this fairly cost effective.
Any help is appreciated, and I am open to all options here!

False you can, up to a .50 over. It's pricey though.
-
yeah you can just hone them out if they are still round and the bores aren't hourglassed. just use a blade hone and go slow
-
I need to measure it all first to make sure I can safely do that.
-
Pelican sells them, so I will assume that they are not that bad. But if I need to go oversized rings I will end up with a new motor....
-
So it looks like the 318 will be sold! Good or bad I do not know, but it gives me the money I need for the swap car.
Guy that will be buying it is a good guy, has great taste, and will take care of my baby. It is amazing that You can get so attached to a car. But I know that its going to good hands.
