This is darn pretty good. Looks like the low end power is limited due to cams but it opens up nice and smooth later on! Imagine puting this motor in a brand new miata lol! You wouldn’t even feel the loss of power in low rpm due to curb weight;)

If ya don't mind me asking, how much was the build? And obviously this wasn't done for efficiency lol but what kinda mileage are ya gettin?

Over 15k counting parts and labor is my guess

Nah not that much at all. Reusing my stock block and heads I think the whole motor cost a little less than $12k including all parts and labor for assembly. I pulled the motor myself so didn’t pay for any labor other than putting the engine together. Way more than $20k into the whole car itself, but that’s with T56 swap, coilovers, fuel system, seats, etc. Here’s a pic from when I pulled the motor. Make sure to drain your transmission fluid beforehand :headbonk:
As for MPG, no realistic number for you there. I’ve been beating on it pretty good since first start and already has a track day under its belt in the few weeks it’s been up and running. Probably like 6 or 7 on E85 thus far.

Nice!! I like the pic. And if your worried about mpg you shouldn’t be thinking about building a motor and adding hp in my opinion. You need to be driving a Prius. MPG has NEVER been a deciding factor in a build.

And you saved a shit load of money by doing a lot of the work yourself. Otherwise I’m sure you would’ve been upwards of 15k

Holy hell people still do their own work? LOL I thought people only cried about dyno numbers anymore!!Nah not that much at all.

LOL I do both!
Another interesting thing from reviewing the datalogs. The MAF is peaking at 66lb/min on that pull to 8100 which seems like a whole lot to me. I looked back at my logs from when I had the Paxton @ 10lbs and the MAF was reading 74lb/min. I made right around 700 on E85 with that setup so I'm even more confused now. 8lb/min = 170HP evidently. It seems like its flowing plenty of air. In any case I'm gonna send the manifold off to Brett Barber to be ported.
Just a thought, the dyno pull was done with my second batch of high zinc break in oil in the engine. Does that have more friction than a normal synthetic maybe and the engine was having to work harder to spin? I might take it back to the dyno now that I'm back to synthetic just for fun and see what happens.

Time to play leaking valve seals or piston rings!
Here’s what every single piston looks like.
And here’s what every single intake port looks like. The tops of the valves are wet with oil so I’m guessing valve seals? What the hell man...

Got a good catch can setup on it? What kind of tension rings did you put in it? Leakdown it. Depending on the tension of rings, and the catch can/breather setup, that might be the way they look.

Here’s my catch can breather setup. I thought it was pretty good but if you see room for improvement I’d appreciate the input.
Not sure about the ring tension since I let the builder spec those. Bought a leak down tester yesterday so I’ll use it today and see what I can find. I’m still not sure how blowby would result in oil on top of the intake valves and all up in the intake ports. The catch can is vented and does not return to the manifold
