Epically epic. Can't wait til you get it all back together!

Your buddy should get a set of personalized plates, though

I know of one other Jalpa in the PNW- an acquaintance of mine has a red one. He's in Bellevue/Redmond area.

I bet that visit helped motivate you!

A red Jalpa? Now that's exciting to hear of another running around. They're so hard to find these days. Running or not running, just finding one is a pain. That's exciting to hear there's another one around here. Tell him if he ever wants to do a PNW Jalpa meet sometime when mine is done to get in touch. Would love to meet him!

The visit was incredibly motivating. Chris has a quicksilver exhaust on his jalpa and it is absolutely intoxicating to hear.

LOL! Not a bad idea. I do want custom plates, and I have no idea what I want to do.

You and me both! I'm excited to play with MS3 since I've been limited to experience with MS1 this entire time. I've only heard good things so far and I'm glad I'm going to stick with something I'm at least more familiar with.

This is such a fantastic build. OMFG.

I'll bet this car will appreciate pretty significantly, too. Seems like everything Lambo and Ferrari is skyrocketing at the moment.

I love seeing a car of this significance in a humble suburban garage. Awesome.

Well, I've hit a snag. Machinist called me on saturday. He finished honing the cylinders. Unfortunately, 2 of them have some deep pitting from everything sitting in the cylinders for so damn long. He said by the time we bore it out the material would be a bit too thin. I was ready to send off one of my pistons for R&D to get them made, and he said "WHOA, wait, we need to figure out what we are going to do here because this is going to make the difference between oversize and stock size." and I went, "E36 M3."

He recommends 2-4 new cylinders/liners depending on how the last few hone out (he has 2 more to do). Thing is... these puppies don't sit in the block like most engines. I can't just bore the block out and drop new liners in. Instead, the cylinders are more like a Porsche, where the cylinder itself isn't part of the block and is removable. But... also kind of not.

There is a smaller diameter on the bottom and a larger diameter on the top, and then it slides into the actual block and seals with a gasket, along with the pressure of the comp gasket between the cylinders and head to make a total seal. So... they're a wet cylinder/sleeve.

My dilemma is:

A. I order new cylinders/liners from lamborghini. These are special order. So if anyone has them in stock I'll be lucky. Otherwise, if not, they special make them, and slap 15% on top of that for each part.

B. I get custom cylinders made from some place that makes custom "sleeves" (even though technically these are cylinders, I think it could be done).

These are an odd setup and I haven't worked on an engine with wet sleeves like this, so I don't even know where I'd go to find a place that would do this. Anyone have any engines that they've dealt with where they've done this?

As you can see, not a lot of material to work with here.

Could you have the sleeves spray welded and then machined? I guess I don't know enough metallurgy to know if that's a viable option.

Grasping at straws here, but the Triumph TR4 engine had Wet cylinder/sleeves. You might contact a performance Triumph Engine builder for advice.

That's a good question, and I do not know enough about metallurgy either to answer that. If someone is able to chime in on that though, that'd be interesting to know.

Good idea, I'll give them a call today. My machinist gave me a few numbers of different places he's had sleeves done in the past, but those are just sleeves, not wet cylinders. I'll give them a try anyway.

Thanks guys.

Alfa's have a similar setup to the one you describe. Might cross check with some alfa specific places too...

If they are similar to porsche they arent nikisil lined are they? (i.e. not machinable?)

I see they have a flat rate repair service, I'll give them a call and see what they can do. If they can be saved, that would be amazing.

I wasn't aware of that. Never worked on one but i'll poke around and see what I can find. That's good info, thank you.

No, these are not Nikasil lined. Some of the other motors were, but not the Jalpa motor.

Lots of general aviation aircraft motors use similar sleeves/cylinders (though not wet), maybe one of the companies that repairs those can work on yours?

I want to say a lot of heavy duty diesel stuff uses wet sleeves. You might find an answer in the smaller marine diesel stuff, like a sailboat engine.

You guys are all an enormous wealth of information. This is easily one of the greatest forums on the net. I love this community. Thank you for all the help and advice. I'm going to dig into these posts and see what I can find out. There's a solution out there somewhere.

Considering Lamborghini made a lot of tractors and heavy equipment, it would make sense logically that they would adapt some of that technology to their road cars.

Serious technical question, because metallurgy is an interesting thing and alloys and expansion are not something I am really good with.

Is it a bad idea to reproduce 3 of the sleeves/cylinders and use them with the stock cylinders? Will it potentially cause a problem with the expansion rates being different? Will it be enough to worry about? Do I really need 8? I trust my machinist, but I am also not sure if something like a sleeve/cylinder is that big of an issue in this case, i'd be more concerned with the expansion of pistons.
