Build Thread?
-
Got some parts from kurt this weekend, some random trim, a set of ellipsoids, an ix booster and some other small stuff. At this point I am just trying to figure out how far to go with the motor rebuild.
-
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.
