Thanks! We'll try to keep getting Goblin videos out! Have a couple extra projects this winter so they'll be mixed in. I'm sure it'll be good once the "new" engine is built and put in!
Nice! A local guy to me that we autocross with (Dsteinhorst with the pink Goblin on the forum) did a supercharger setup on his 2.2 but he hasn't built the motor yet so he's still running low boost. It's actually the whole supercharger setup off my car from when I swapped to turbo!
@WOT club when you build the engine, can you do a in depth breakdown of the build. Machine shop stuff oil clearance piston to wall clearance and gapping the rings. That would be great!
I don't think I'd say that. The donors are much more expensive and then you also have to deal with direct injection. If I did it again I'd still get a supercharged donor and turbo it.
It would be interesting to see an engine swap to some other GM motor in this build, as I know some of the GM High Feature V6s share transmission bolt patterns with the Cobalt and I imagine an engine side mount could be made, if they aren’t the same already.
Based on our assessment it got too hot so under hard boost the stock ring gap wasn't enough and it blew the piston to bits. It won't have a whole lot, just aftermarket pistons, new rings(gapped a bit more), and ARP head studs. We probably should have checked engine #2 over more before stuffing it in the car because it's a blowby issue and we should have found that before going through all of that hassle for nothing.
It was around 18lbs if I remember correctly. The problem, that was discovered after the fact, was that the intercooler pump stopped working so the intake temps were skyrocketing which also caused the coolant temp to go up drastically so there was quite a bit of extra heat expansion happening in the cylinders.
Beautiful build 🏎️🏎️💨
Thanks!
I enjoy the goblin videos! I'm sending mine for powder this week. Hope you get the boost situation figured out!

@WOT club after I get mine running I plan on doing a full engine build of the 2.2l and supercharging can't wait!!

I'll see what I can do!
So your saying just get a turbo donor cat to start?
I don't think I'd say that. The donors are much more expensive and then you also have to deal with direct injection. If I did it again I'd still get a supercharged donor and turbo it.
That thing is so sweet! The hard work will pay off! 😁

I'm not sure that it'd be worth the effort. Everything was designed around the Ecotec so you'd have to do some sizable modifications I'd imagine.
Really digging the wheels who makes them?
The wheels are from Kansei. I hadn't heard of them before getting them for this car but they seem like a pretty decent quality wheel.
Good vid! What was the root cause of the cylinder failure? What upgrades is engine #3 going to have?

@@WOTclub wow. The rings blew apart the sleeve before the rods let go. How much boost were you running?

Boost to hight 50psi injectors
Imjeter fule real size timeing ECU
Who tuned it for the turbo, or did you just have a zzp base map?
It was dyno tuned by Capital City Performance in Madison, WI.
Nice
Thanks
what happens when theres no more donor cars
No more Chevy Cobalts?? Seems unlikely that we'll run out of those but I suppose then they just build a kit for a different car.
