Not always great looking though. I have a similar tank on the engine that replaced the air oil separator.

That's really interesting, I had never thought to look for used nascar equipment.
What's the purpose of the aeration? Faster cooling?

The aeration isn’t by design, it’s due to oil basing through the fast moving turbos. It’s a bad thing

Oh got it, I read your post incorrectly. I didn't think aeration was a good thing but I didn't want to question lol. Keep us posted!
Btw, did you find a wire to use for your turbo oil pump? Or are you gonna use an aftermarket timer.

Question: Are you going to put a little scoop or something over the turbo holes to try and direct some cool air towards the intakes? It might not be much, but I can see them sucking in some warm air. Might not be a big deal, but it might be something to think about.
Also, that exhaust setup is going to look and sound MEAN.
Random thought; is yours still registered for road use? This will be the most fun errand runner ever.

I need to figure out a way to get some cold air in there, although its a track car so it'll probably be getting plenty of cold air at 100mph+ just with the openings.
It is actual registered and insured for the street but hasn't been on the street in a long time. It attracts way to much attention for me. Next year itll be 25 years old and registerable as classic in VA so that allow me to bypass the state inspection which it of course would not pass.

OK one more photo because I'm just so pumped about how this is turning out. And yes it'll be wrapped like the rest of the car

If the spacer is the issue, you might be able to fabricate one based of the bell housing and specific clearance you need. Here's what I just found on eBay, but not sure of the thickness...

Yep, 1990 Lotus Esprit SE Turbo. It runs and drives, no real problems. I sold my 911 and bought it last week. Its a hoot to drive at any speed, I never considered these as mini-super cars but the year this was made (1989) it was faster to 60 than a Countach..also the exact same width and 6's longer than the lambo. Whether or not its 90s supercar territory it definitely scratched the itch for me.

and baby approved!

thanks! I have not driven it yet, I live in the city and it certainly not street legal so the first time I'll drive it will be on the track...which is terrifying. It will go to the dyno before the track so thats a bit of a trial run
