the boring but meticulous 2.7i

Here's a pretty engine picture.

Awesome!

Nice, what do you think of it?

Well done!

Post up some first impressions on the drive characteristics.

So what's your recipe? I am just about to start an M20 build myself!

Congrats on a fine finish, looks great.

Haven't driven it much; so far I've noticed that it has eta torque but doesn't stop pulling after 4500. Sounds fierce, loves to rev. Now I know what people mean about M20s being rev happy :)

I'm having idle troubles, though. Specifically, cylinder 6 misfire. Upon cold start, it idles ok for ~20 seconds, then starts misfiring. It revs smooth, pulls hard, and starts almost instantly, but at idle cylinder 6 is missing. Hoping it's the plug wire I spliced to get the cylinder ID sensor on it; ordered a new OEM one. The resistance matched the other plug wires but it could be arcing at the splice. C191 pins check out for continuity.

Exhaust symphony
Start, idle, and rev

Input appreciated, I'm kind of a noob!

Another pretty engine picture, and a before picture. Some difference, huh?

I think going from e to I cleans the bay up nicely. Your bay definitely looks cleaner/tidier than the swap I just finished lol.

Update: turns out my valves were way too tight. Adjusted them to 0.012.

This thing is a fucking animal. I got it up to 90 and it was still pulling hard. For all those who hate on flat-top piston builds: 8.4:1 compression is plenty. Even with a 2.93 it's a hoot. Can't wait until I get the 3.25 LSD in it. Wooooooooo!

You need a 3.73 :)

Good job man!!!

I'm in the process myself on building a full 2.7i build. Pretty much got all parts together, just been procrastinating... Hehe

This.

I have a 3.25s in mine and it is too tall.

Why do people hate on flat top builds?
Would the "i" pistons on e rods be better?

I feel like pretty much every time someone asks about a 2.7i build, someone always says it will be garbage because of the lower compression, even worse than a 2.5, you can't do it without SETA pistons, etc.

It's awesome, haters gonna hate. Skewing information for probably the best mod you can do to an eta.

I'll see how I like the 3.25, this car is mainly going to be a high speed highway cruiser but I guess if 3.25 is too long I can always source a 3.73. Wanna keep some semblance of fuel efficiency. It's fun enough with the 2.93 that I'm not terribly concerned about it.
