Thought I could beat the system....

Fixed.

I like your new diagram. 
The 12v while cranking is usually sent to the unloader relay chassis side.

ooo, pretty diagram. youll be rewarded by not having a spaghetti mess in the end and troubleshooting will be systematic instead of guesswork. you can put the time in now, or the time in later, but the time gods must have their fill.

I do love the printed labels on the Megasquirt  DIY harness

Exactly.

[HipMF]

Pretty sure e21s don't have an unloader relay, so that's easy.

Also considering getting a label printer for doing wire labels.

I have wire number labels, but I don't think they'll hold up well enough. I've heard clear shrink tube is a thing and works well for protecting labels...

Wow I need to log in more often. This is sweet!!

[The Full Banana]

Printable heatshrink labels with clear heatshrink over it to protect it worked great on my harness.

Digital version. Needs validation. Any volunteers?

Picked up a dozen tamales and some pastor meat for tacos at Abarrotes El Primo in Sun Prairie before heading up to the shop this morning. May have reached a new high water mark as far as shop cuisine is concerned.

damn that looks good.

Of course this would happen on a weekend I'm gone!

Do you have a recipe for this creation? It looks restaurant quality.

Thanks. The meat from El Primo is pre-marinated. All I did was fry it in a hot cast iron pan on a camp stove.

I have made my own meat using the recipe from Serious Eats, but that one is braised in the oven. You could probably use the same marinade and just fry the meat instead of braising it. Al pastor is traditionally made on a vertical spit like gyro meat, so it's not really something you can do at home.

I'm just now finally getting the hang of heating tortillas properly...

I need a cast iron pan. Tortillas are a major part of the taco experience.

I have one piece of 2" in my charge piping. Unfortunately it's too small to fit over the die of the bead roller, so I had to improvise. Worked pretty well.

Also spent way too long working on a bracket for the wastegate actuator now that the turbo is re-clocked.

Also got the driveshaft installed and some other small things. Basically anything to avoid working on wiring at this point.

Internal gate huh. what turbski is that you are running?

TD04HL-15G from a Volvo 850 R

From the beginning, my goal has been to get the car down to 10 pounds of mass per horsepower. The car will probably only be used for autox and cruising, so I'm more concerned with throttle response and spool time than I am with trying to impress people with big horsepower numbers. I'm planning on a finished weight around 2300 or 2400 pounds. This turbo makes around 235hp on a stock 2.3l Volvo motor at low boost pressure, so I feel like it's a good choice for this application. As seen above, peak efficiency of the compressor is around 4500-5000 rpm on the 1.8l; not good for a race car, but if we're being realistic, that's a good place for it to be given the way I plan on driving the car.

Interesting tidbits: Since the Volvo engine is almost 30% larger, I'll have to run a higher boost pressure to get the same number of horsepowers. Looking at the compressor map above, we can easily see that generating the same flow rate (hp) at a higher boost pressure puts us in a much better place on the map than we would be with the 2.3l at high rpm. On top of that, higher boost pressure naturally means higher back-pressure in the exhaust. Exhaust back-pressure is always a Bad Thing (don't let anyone tell you otherwise). However, if we're stuck with a particular exhaust restriction, then increasing the pressure differential across it will increase the flow rate through it. TL;DR: The same turbo will generally be capable of making more power on a smaller engine than it would be on a larger engine.
