Sweet.
You know to not let the machine shop acid/caustic dip the block, right?

I did not! Thank you for the help! How should I ask them to clean it, or should I do it myself?

Exciting!

I would really appreciate some commentary about your dealings with megasquirt when you get things up and running. I am going to be watching this thread.

I will do my best! I am probably going to go with a DIYPnP made by WhodWho, I've heard a ton of good stuff about his boxes. Plus it saves me the trouble of making my own!

What are the short skirt b25 pistons out of? The m20b25 or the m50b25?

I recently rebuilt an 885 head. All new valves, new Febi rockers, 272 billet cam, the works. Then tossed it on my 2.7L flat top bottom end and thus created the 2.7L budget stroker that put down 150whp/148tq when it wasn't even tuned. It was fine for a while but I've recently noticed that the rings seem to be letting go of some oil and I decided to rebuild my bottom end. But not just ANY rebuild, I am building it to 2.8L!

Build specs:
M52 crank
130mm eta rods
Short skirt B25 pistons
Hoping to eventually run MegaSquirt

This weekend I tore down the spare engine that I will be getting my bottom end from. This way I can build a 2.8L while I can still drive my car.

Can you tell I was cutting corners? :)

Me thinks there was oil in the coolant...


Also got the rods and pistons out yesterday, but forgot my camera. Going back today and I will get some pictures. Really hoping to be able to drop off the block at a machine shop some time next week so I can start the assembly process.
