So I'm taking a break from the engine work for a minute. Here is an update of tonight's activities:
Buffed the gasket residue off of the head surface, one of the techs and I took a straight edge and feeler gauges to it and found that it is not warped at all, so great news there, and less work later.
Then took the straight edge to the turbine outlet, found the one problem spot that I knew existed (because there was exhaust residue on the hood :vash: ) and got it straightened out.
Told my buddy that I needed to take the EGR elbow off the manifold since I'm plugging it (don't have the valve, might as well finish the delete), walk off to get a tool I needed, when I hear him grunt and then say "Oops." The elbow didn't exactly turn, so the fitting in the manifold sheared off. So now I have to remove the manifold from the head and get the turbo off so that we can extract what's left. Oh well, can't complain about free help from a master tech.
In any case, when I'm done with my break, I'm taking the pistons out of the MSM motor, and then I'm quitting for the night.
Pictures up later this evening maybe.

This project must be surrounded by shitty luck... I pulled the pistons and rods out of the MSM donor block just a few minutes ago, everything went fine. Start cleaning everything up and find that one of the pistons has two small chips on the corners of the dome, definitely not usable. Fuck!

My CAT forged rods got here today though, so that helped the bad mood I was in on the way home from the shop:

So what are you going to do about pistons now? Forged? Or cheap used ones. I think somone here had some for free...search for sale section...

RotorNutFD3S 08-08-2008 11:21 AM

I'm going to find another set of used OEMs. The free ones on here are already gone, Ben had tried to get those for me. I have a lead on some 9.0:1 out of a '96 though.

Got the pistons in my hand. The damage on #3 piston looks like detonation to me.

This motor looks like it was run HARD. The block is great though for someone's rebuild.

wildfire0310 08-08-2008 04:10 PM

hey Eric

Steven I think still has the pistons and rods. Now that you have the forged one you don't need to worry about the lack of end caps. You could at least check out his pistons. If anything I will try and get him to bring them to the meet tomorrow and I will look at them for you and take some pictures.

Call or text me about it if you want.

BTW the rods look bad ass.

zarish 08-08-2008 04:43 PM

RotorNut man get this ASAP. Sell your rods to someone and just pick up a 99 head. This is a really good deal for $300 dollars. Hurry its gona end soon. This block already has je pistons,paulter rods,arp main studs,turbo drain installed,turbo feed installed, head gasket, timing belt, pulleys, water pump, oil pan. everything in the picture is included.
If I my car didn't have a 1.6 I would have bought this thing.

Ben 08-08-2008 05:31 PM

hmm, it's local but I'm not sure if a 94 block with 25k hard boosted miles is worth that kind of money. I think he's on a better path with billet OP gears, forged rods, coated pistons, and MBSP. Built and balanced FTW.

RotorNutFD3S 08-08-2008 05:52 PM

Brian, Stephen just called me back on them. I'm going to see if I can make it to the meet tomorrow, inspect them, and buy them. Just take Britt's Miata. Thanks though!

Yeah, that's a damn good deal considering the price of the parts, but Ben makes a good point. Also, he told me the seller has some bad history that I think I will avoid. And the pistons look like crap, black in the middle and white on the edges, it's been dogged.

Ben 08-08-2008 06:01 PM

That's the motor from the guy who ripped off Bruce (olderguy) and some other people. That motor he sold to somebody and never shipped, don't remember who though.

Bad karma there.

Thanks man! LagunaRoadster is selling me the pistons out of his '96 motor. If there is anything wrong with them, which there shouldn't be, I'll give you a call.

Eh, figured you'd read the thread and see. But oh well. They are very nice, can't wait to put them to good use! Thanks again!
