Thanks OP! Order and received six.

Thanks!

Thanks!

Thank you!

Agreed. Or dig around your garage and find something to slip over the spark plug wires to act as a sheath. Another alternative...zip tie the plug wires together, then secure the zip tie holding the wires with another zip tie secured to something (bracket, bolt, etc....). This provides a bit...

Cams and harmonic balancer installed with voodoo friction washers. Everything appears to be in time. The engine turns over by hand and I don't feel or hear (or feel) anything terrible. The +90 degrees on the crank bolt is a bit of a bear by myself but I got it. Next up - porting the intake...

Yup! I picked up timing tools from Amazon. This is my first time timing and engine and I can't say I'm thrilled about the process of timing an MZR. To your point, having the engine on the stand should make it "easier".

The MZR 2.0 and 2.5 have variable valve timing on the intake side. Attached are some pics. Given this is my first engine swap, I'd be out of my depth swapping in a V8. That said, I'm open to forced induction in the future. We'll see....🙃

Indeed. For the swap, I need to use the oil pan from the 2.0 to clear the cross member. With the 2.0 oil pan, the balance shaft assembly simply won't fit. I'll be using a Fluidampr harmonic balancer to help mitigate vibration.

We've got updates! New rear main seal installed. Balance shafts deleted. Balance shaft delete plug installed.

New harmonic balancer/pulley arrived today. Snagged this as dropping the 2.5L into the Miata requires deleting the balance shafts to use the 2.0 oil pan which is needed to clear the cross member. A fancy balancer seemed like a good idea as I'm planning to run a lighter weight flywheel and I'd...

Shhhhhhh! Don't tell my wife...already in my long-term plans.....

Nope. Rigging up an ECU, fueling, etc... would be neat, but I don't have infrastructure outside the car to make that happen. Going to install the 2.5, pray, and turn the key.

Coffin on wheels! ;) Yeah, I'd love to test drive a Miata with a V8.

Exactly! I'll be in about $3 to $4K with this swap. I'll post some of the fun bits I pickup on the way. And for the record, I deleted the expense column from my spreadsheet as sometimes it's better not to keep track of these things. LOL

Top Tip! Thoroughly clean your $320 junkyard motor before digging in! I mentioned "surprises" in my initial post and here we are.... Pulled the oil filter housing off today—smooth move, right? Well, not exactly. Turns out there was a nice little ridge of dirt, sand, dust, debris, etc.. where...

Ahhh, yes. The cleaning wonders of old school multi-port fuel injection.

@Ronsant - Welcome to the thread! My 2.0 failed with ~123k miles. Your 2.0 with 8k miles will likely serve you well for many, many years. Drive and enjoy it!
